Which Galaxy devices support Galaxy AI — and what’s different on S26

What is Galaxy AI? It&rsquo;s Samsung&rsquo;s built-in set of artificial intelligence (AI) tools for select <a href="https://www.att.com/buy/phones/browse/samsung/">Galaxy phones</a>, <a href="https://www.att.com/buy/tablets/browse/samsung/">tablets</a>, <a href="https://www.att.com/buy/wearables/browse/samsung/">watches</a>, <a href="https://www.att.com/buy/accessories/browse/headphones/samsung/">earbuds</a>, and Samsung apps. Instead of opening a separate AI app, you&rsquo;ll find Galaxy AI inside calls, messages, photos, notes, search, productivity, and daily alerts.

Some features run on the phone, and others use the cloud for more demanding tasks, such as generative photo edits. For most people, Samsung Galaxy AI can mean faster translations, cleaner photos, sharper notes, and smarter help in the apps they already use.

Galaxy AI is built into the foundation of supported Galaxy devices and Samsung apps. It can help with everyday tasks, such as translating a call, summarizing meeting notes, cleaning up a photo, and finding content in supported Samsung apps. Its value depends on your device, apps, and how often these tools can reduce steps in everyday tasks.

<h2 id="galaxy-ai-isnt-a-separate-app--heres-what-makes-it-different">Galaxy AI isn&rsquo;t a separate app &mdash; here&rsquo;s what makes it different</h2>

Galaxy AI isn&rsquo;t one app you download. It&rsquo;s Samsung&rsquo;s name for artificial intelligence features built into One UI, the Galaxy operating system. It&rsquo;s also built into Samsung apps such as Phone, Messages, Samsung Notes, Voice Recorder, Gallery, and Samsung Internet.

You don&rsquo;t always have to open a separate assistant or type a prompt. Galaxy AI can show up based on what you&rsquo;re doing. For example, translation can appear during a call. Note help appears inside Samsung Notes. Photo tools sit inside Gallery. Search can work on the screen you&rsquo;re already viewing. That can mean fewer steps, less app switching, and more help handling tasks while you stay in control.

Galaxy AI doesn&rsquo;t process every task the same way. Some features run right on the phone, which can improve speed and privacy. More demanding tools, like generative photo editing, may use cloud processing to finish the job.

Samsung described the Galaxy S26 series, launched in February 2026, as its third generation of AI phones. The company said the phones can handle complex tasks in the background, so users can focus on results instead of the technology.1

Galaxy AI works best when it helps handle everyday tasks and reduces the number of steps you need to take, such as making calls, editing photos and videos, and organizing notes.

<h2 id="the-galaxy-ai-features-youll-actually-notice">The Galaxy AI features you&rsquo;ll actually notice</h2>

The Galaxy AI features most people notice first are the ones built into everyday phone tasks: calls, photos, videos, notes, messages, and search. In general, they fall into four areas: communication, photos and videos, productivity, and search.

Because the tools appear inside familiar apps, they can be easier to learn. You can translate a call, clean up a photo, summarize notes, or find content in supported apps without moving everything into a separate AI app.

<h3>Communication and translation</h3>

Live Translate provides real-time translation during phone calls, and the person on the other end doesn&rsquo;t need a separate app. Interpreter helps with in-person conversations by showing translated text or playing translated audio. Language support varies by region, device, carrier, and software version.

The Galaxy S26 series adds Call Screening. When an unknown caller reaches you and you&rsquo;re unavailable, on-device AI can answer, ask for the caller&rsquo;s name and reason for calling, and save a recording and transcript for review.2

<h3>Photos and videos</h3>

Photo Assist helps edit images in Gallery. You can move or remove objects, clean up backgrounds, adjust scenes, or describe changes in plain language. Samsung labels images when generative AI changes the photo. This helps show when AI altered or created part of the image.

Samsung also extends Galaxy AI into video and creative design on the Galaxy S26 line. Advanced Audio Eraser can reduce or isolate background sounds while you watch videos, including some videos in third-party apps. That can make dialogue or key sounds easier to hear.

Creative Studio lets you generate drawings, stickers, wallpapers, and shareable cards from a sketch, photo, or text prompt.

<h3>Search and productivity</h3>

Galaxy AI can help you find content in supported Samsung apps. With AI-powered Gallery search, you can type a few words into the search bar to find specific photos in your Gallery. In Settings, you can type a question or describe what you need, such as finding a document on your phone.

Galaxy AI can also help organize everyday tasks and reduce the number of steps you need to take.

<ul>
	<li>Note Assist in Samsung Notes can summarize, organize, and reformat notes.</li>
	<li>Transcript Assist turns voice recordings into searchable text.</li>
	<li>Writing Assist can help with spelling, grammar, phrasing, and tone in supported apps.</li>
</ul>

Together, these tools show where Galaxy AI can be most useful: helping you finish common tasks with fewer taps, less app switching, and less manual cleanup.

While these tools can save you time, the same feature set isn&rsquo;t available on every Galaxy phone. It&rsquo;s important to check which Galaxy AI features are available on each device.

<h2 id="the-galaxy-ai-features-running-in-the-background">The Galaxy AI features running in the background</h2>

Some Galaxy AI features work quietly in the background. Samsung designed these features to make supported phones feel more helpful without constantly reminding you that AI is involved.

Now Brief creates daily summaries based on information already on the phone, such as calendar entries, messages, app notifications, weather, and travel details. Instead of opening several apps, you can see reminders, schedule items, reservations, and timely prompts in one place.

Now Nudge, available on the Galaxy S26 series, brings that idea into more specific moments. For example, if a friend texts asking for photos from a recent trip, the phone may suggest matching images from Gallery.

Samsung describes this direction as agentic AI, meaning the phone can suggest or take limited action based on context while you stay in control.

Which Samsung devices support Galaxy AI? Feature availability varies by supported Galaxy S series and Z series models.

<h2 id="which-galaxy-devices-support-galaxy-ai--and-whats-different-on-s26">Which Galaxy devices support Galaxy AI &mdash; and what&rsquo;s different on S26</h2>

Galaxy AI launched with the Galaxy S24 series in January 2024 and has since expanded through software updates. Galaxy AI is supported on compatible Galaxy S series and Z series devices launched after January 2024, with select features expanded to older models such as the Galaxy S23 series.

You don&rsquo;t always need the newest Galaxy S series or Z series phone to use select Galaxy AI features. Samsung has expanded select Galaxy AI features to older models to make AI tools available to more users around the world.

Availability varies by model, market, carrier, app, language, and software version, but many supported devices can access features such as Live Translate, Note Assist, Writing Assist, Photo Assist, Audio Eraser, and Transcript Assist.

The Galaxy S26 series adds features that may not be available on older devices. Samsung and industry reports identify Advanced Audio Eraser, Call Screening, Creative Studio, and improved Photo Assist as major S26 additions.3&nbsp;The S26 generation also brings improved Circle to Search to help you &ldquo;shop the look.&rdquo;

Samsung also says on its Galaxy AI page that &ldquo;Galaxy AI basic features provided by Samsung are free.&rdquo;4&nbsp;New or enhanced features may cost extra, but the baseline Galaxy AI experience on supported devices doesn&rsquo;t require a subscription.

The S26 line may offer you the most complete Galaxy AI experience, but older supported phones still get many of the everyday tools people are likely to use most.

So, what is Galaxy AI in practical terms? It&rsquo;s Samsung&rsquo;s built-in set of artificial intelligence tools for supported calls, photos, notes, search, media, and daily prompts. It isn&rsquo;t one app or just a chatbot. It&rsquo;s a collection of features across supported Galaxy devices, with the S26 models getting the most advanced tools.

Online shopping lets you browse for deals anywhere, compare products, and get items delivered straight to your doorstep. While buying your items online is convenient, safe online shopping is important.
Purchasing online can expose you to data theft and scams—some sites may take your payment but never ship the items. Stay safe while shopping by:
<ul>
<li>Using secure websites and payment methods</li>
<li>Regularly monitoring your transactions</li>
<li>Watching for red flags (scams)</li>
</ul>
Keep your financial and other sensitive information safe from bad actors with a few helpful online shopping safety tips.
<h2 id="shop-only-on-secure-and-trusted-websites">Shop only on secure and trusted websites</h2>
Start with trusted retailers that prioritize security, reliability, and a positive customer experience. New or unestablished sites may have fewer security resources—or may simply be untrustworthy.
Look for sites that use Hypertext Transfer Protocol Secure (HTTPS), which helps protect your personal information. HTTPS encrypts (scrambles) data sent between you and the site, making it harder for others to read without a decryption key. You&#8217;ll typically see “https” in the URL or a padlock icon in the address bar.
Online scammers often create sites that look legitimate to defraud shoppers of their money. Type the URL carefully because malicious pages can mimic legitimate shopping platforms. Double-check the spelling, or use bookmarks or a search engine to reach the site.
Even if the connection is secure, check contact details and reviews before you shop. If you encounter an online shopping scam, report it to the platform and the appropriate authorities.
Before shopping anywhere, ensure that you’re protecting your devices and accounts.
<h2 id="protect-your-devices-and-accounts">Protect your devices and accounts</h2>
When shopping online, keep your computer and <a href="https://www.att.com/blog/4-tips-for-improving-your-phone-security" target="_blank" rel="noopener">phone security</a> settings up to date by regularly updating your antivirus, operating system (OS), and apps. The latest versions include protections and security fixes against new threats and scams.
Use strong, unique passwords (a combination of letters, numbers, and special characters) or passphrases for all your accounts—and store them in a password manager. Turn on multi-factor authentication (MFA) to keep your accounts safe.
One-time passwords (OTPs) and authenticator apps add a second step, making it harder for anyone to access your accounts.
Use network-level security, such as firewalls, to block malicious sites and scan your home network for vulnerabilities. Run reputable antivirus and antimalware programs and actively monitor your devices for suspicious activity.
Consider fraud-monitoring apps and to scan the web and alert you if your identity is being misused. Choose <a href="https://www.att.com/internet/" target="_blank" rel="noopener">reliable internet</a> with built-in security tools and the right <a href="https://www.att.com/blog/what-is-the-att-activearmorsm-mobile-security-app" target="_blank" rel="noopener">security app</a> to alert you to data breaches, help block scam attempts, and add protection across your favorite shopping platforms.
This is crucial for keeping your identity, accounts, and payment methods protected.
<h2 id="use-safe-and-secure-payment-methods">Use safe and secure payment methods</h2>
When you shop online, use a credit card rather than a debit card. If there’s an issue with your order—the wrong item, failure to deliver, or card fraud—you’ll have more ways to recover your money. For scams or unauthorized purchases, credit cards let you initiate a chargeback through your bank.
Save digital receipts and order confirmations. You may need them if there’s an issue with your purchase or if you need to contest a charge with your bank. Monitor your transactions regularly to catch problems early. The sooner you spot a fraudulent transaction, the faster you can report it and start recovering your money.
Even if you use secure payment platforms and credit cards, hackers may still access your payment information if you shop on public Wi-Fi.
<h2 id="avoid-public-wi-fi-when-shopping-online">Avoid public Wi-Fi when shopping online</h2>
Always use private wireless connections rather than public networks to reduce the risk of data or identity theft. Private connections help ensure your payment details and personal information stay protected.
On public networks, hackers may intercept unencrypted traffic or set up look-alike Wi-Fi networks to harvest data.
Wait until you’re home to make online purchases to avoid the dangers of unsecured Wi-Fi. If you must shop on a public network, take proper Wi-Fi security precautions and use a virtual private network (VPN) to protect your location, identity, and information.
Thanks to the benefits of a VPN, it’s generally safer to use a private wireless connection than a public network.
When you focus on security and other best practices, online shopping has plenty of advantages. That’s why staying sharp is crucial to staying safe online.
<h2 id="shop-smarter-and-safer-online">Shop smarter and safer online</h2>
Safe online shopping means using secure sites, making payments through trusted processors, and browsing on protected devices. Protecting yourself from fraud, scammers, and identity theft starts with a reliable <a href="https://www.att.com/wi-fi/" target="_blank" rel="noopener">home internet connection</a> and dependable <a href="https://www.att.com/wireless/" target="_blank" rel="noopener">wireless services</a>.
With us, you can get both. Pair your services with <a href="https://www.att.com/security/" target="_blank" rel="noopener">AT&amp;T ActiveArmor</a> to experience the best online shopping protection possible.

Online shopping safety tips

With a quick swipe, you can do almost anything on your phone—snap photos, store important files, connect with <a href="https://www.att.com/blog/staying-connected-with-your-long-distance-family" target="_blank" rel="noopener">long-distance family</a> and friends, and more. It’s more important than ever to pick cell phone features that match your needs and lifestyle.
Whether you’re after advanced cameras, ample storage, long battery life, or fast data speeds, there’s a cell phone feature for you. Start by asking yourself:
<ul>
<li>Which functions and capabilities matter most to you?</li>
<li>What would make life easier or more convenient?</li>
<li>Does your current phone have everything you need, or is it time to <a href="https://www.att.com/blog/upgrading-to-a-new-phone-heres-how-to-prepare" target="_blank" rel="noopener">upgrade</a>?</li>
</ul>
From there, check out these 10 must-have features to make sure your phone has everything you need—and then some.
<h2 id="10-must-have-cell-phone-features-to-look-for-before-you-buy">10 must-have cell phone features to look for before you buy</h2>
With countless options out there, focus on the features that fit your life.
Nature lovers may want a rugged phone that can handle water, impacts, and severe weather—like a <a href="https://www.att.com/buy/phones/browse/sonim/" target="_blank" rel="noopener">Sonim phone</a>.
If you love traveling and taking photos, then an advanced camera on the latest smartphone might be just what you need.
Whatever your needs, start with a fast device and a bright, clear screen that can handle your day-to-day activities.
<h2 id="1-a-high-resolution-display-for-crisp-visuals">1. A high-resolution display for crisp visuals</h2>
Your screen is how you see and interact with everything on your phone—so it’s helpful to pick the right display.
Start with screen size. A larger screen makes it easier to see fine details and to tap on apps or fill out forms. Keep in mind: larger screens usually mean a bigger, heavier phone.
Also, consider refresh rate, measured in Hertz (Hz), which tells you how many times the picture on your display is updated per second.
Higher refresh rates make motion look smoother for more fluid scrolling, streaming, <a href="https://www.att.com/gaming/" target="_blank" rel="noopener">gaming</a>, and more.
Check out display technology as well. Many modern phone screens use Liquid Crystal Display (LCD) or Active-Matrix Organic Light-Emitting Diode (AMOLED) technology.
AMOLED (common on higher-end phones) typically delivers richer colors, higher contrast, and deeper blacks, making it ideal for streaming, gaming, and multitasking. LCD screens tend to be bright outdoors, affordable, and have a long life span.
<h2 id="2-long-battery-life-and-fast-charging">2. Long battery life and fast charging</h2>
Using your phone a lot can drain the battery quickly. Constantly charging can be inconvenient and even impractical at times.
Look for a phone with extended battery life to last you through the entire day. Some newer devices can last up to two days on a single charge, depending on use.
Battery capacity is measured in milliampere hours (mAh). The higher your battery’s mAh, the larger its capacity and the longer it typically lasts.
Actual battery life depends on factors like usage, environment (extreme cold and extreme heat can decrease battery life), and charging habits.
Beyond capacity, look for extras like <a href="https://www.att.com/buy/accessories/browse/chargers/fast-charge" target="_blank" rel="noopener">fast charging</a>, which lets you power your device quicker. Plus, with compatible wireless <a href="https://www.att.com/buy/accessories/browse/chargers" target="_blank" rel="noopener">charging accessories</a>, like <a href="https://www.att.com/buy/accessories/Chargers/att-qi2-magnetic-charging-pad.html" target="_blank" rel="noopener">wireless charging pads</a>, you can conveniently power up your device without plugging in.
<h2 id="3-powerful-camera-system-for-great-photos">3. Powerful camera system for great photos</h2>
The right camera lets you capture all of life’s special moments in crystal-clear quality. The days of blurry, fuzzy pictures should be in your past—so it’s worth comparing camera systems.
Learn the basics about filters, <a href="https://www.att.com/blog/what-are-megapixels" target="_blank" rel="noopener">megapixel</a> count, autofocus, and aperture (lens opening that controls how much light reaches the image sensor). Then, you can move on to more advanced features.
Check out multi-lens setups (ultrawide, telephoto). With more than one lens, you can focus on subjects at different distances and under various lighting conditions for enhanced photos.
And don’t forget low-light performance features. These are perfect when natural light isn’t on your side. Use night mode to brighten up photos you take in the dark while keeping the details crisp.
What about video? Look for intuitive editing options and stabilization to help you achieve polished results you’ll be proud to post and share.
With the right features, you can achieve silver screen-worthy photos and video right from your phone.
<h2 id="4-5g-connectivity-for-lightning-fast-speeds">4. 5G connectivity for lightning-fast speeds</h2>
For quick wireless connectivity, <a href="https://www.att.com/blog/why-you-should-care-about-5g-emerging-trends" target="_blank" rel="noopener">5G</a> is the latest standard. With 5G, you typically get faster speeds than 4G, which is great for basically everything you do on your phone.
You’ll notice the difference downloading large files—like movies, apps, or work documents—since 5G generally downloads faster than 4G.
Love streaming content? Thanks to 5G, you can stream 4K Ultra High-Definition (UHD) more smoothly with less buffering and higher quality.
Are you a gamer? If so, you know how lag can lead to a choppy, frustrating gaming experience, especially during online play.
5G reduces latency for a more responsive connection to gaming servers and smoother, more continuous online play.
Most new smartphones are 5G-ready, so you shouldn’t have to go out of your way to find one.
<h2 id="5-ample-storage-and-ram-for-performance">5. Ample storage and RAM for performance</h2>
The storage space you need depends on how much you want to keep on your device (i.e., on your phone rather than in the cloud).
The most common storage capacities for modern cell phones include 128 gigabytes (GB), 256 GB, 512 GB, and 1 terabyte (TB).
To balance local storage with the cloud, combine your phone’s internal memory with <a href="https://www.att.com/features/att-personal-cloud/" target="_blank" rel="noopener">AT&amp;T Personal Cloud</a> to access your files anywhere.
In addition to internal storage, you also want to pay attention to Random Access Memory (RAM). RAM is the memory your smartphone uses for active apps, browsing, and games.
With more RAM, multitasking feels smoother, especially when you have several apps open.
<h2 id="6-regular-software-updates-and-security-patches">6. Regular software updates and security patches</h2>
When purchasing a phone, it’s important to choose a manufacturer and operating system (OS) with a reliable track record.
An up-to-date OS can deliver regular updates, security patches, and bug fixes to keep your phone running smoothly and securely.
In addition to a reliable OS and manufacturer, choose a mobile device with built-in privacy tools. Routine security checks and alerts for suspicious activity can help keep you safe as you browse, shop online, message, and use apps.
<h2 id="7-water-and-dust-resistance-for-peace-of-mind">7. Water and dust resistance for peace of mind</h2>
It’s easy enough to accidentally drop your phone in the sink and get it wet. If your device isn’t at least partially water-resistant, even a small spill can mean a costly repair or inconvenient replacement.
The Ingress Protection (IP) rating measures your phone’s durability against external particles. This two-digit code (e.g., IP67 or IP68) shows how well a device resists dust and water.
The first digit (0-6) rates dust resistance, with 6 meaning dust-tight protection.¹ The second digit (0-9) rates water resistance. A 9 means a phone can withstand high-pressure, high-temperature water.
Regardless of your phone’s IP rating, it’s still best to keep your device dry and clean to prolong its life.
<h2 id="8-biometric-security-for-quick-secure-access">8. Biometric security for quick, secure access</h2>
Many apps use biometric authentication for login purposes and identity verification. Biometric authentication is any type of verification that uses a biological trait, like your fingerprint or facial recognition.
To keep your device secure and protect your accounts, choose a phone that offers fingerprint scanners or facial recognition software.
These biometric options can be more secure—and they’re often quicker and more convenient than passwords.
With just a tap or a look, you can quickly unlock your phone and other apps.
<h2 id="9-special-tools-like-styluses-or-foldable-screens">9. Special tools like styluses or foldable screens</h2>
New devices are constantly pushing the envelope to offer more useful, advanced cell phone features than competing models.
Two extras that can make your phone more intuitive, fun, and convenient:
<ul>
<li>Styluses – A stylus lets you pinpoint small areas of your screen, navigate accurately, and draw or take notes with precision. Some phones (like <a href="https://www.att.com/buy/phones/motorola-moto-g-stylus-2025.html" target="_blank" rel="noopener">Moto G Stylus 5G</a>) come with a stylus. If not included, consider a universal stylus compatible with your phone.</li>
<li>Folding phones – They’re compact when folded and open to a larger screen, making them convenient for surfing, streaming, chatting, gaming, and multitasking.</li>
</ul>
These accessories are a great way to optimize your phone, whether you use it for school, <a href="https://www.att.com/blog/remote-work-setup-for-beginners" target="_blank" rel="noopener">remote work</a>, or entertainment.
<h2 id="10-compatibility-with-your-network-and-lifestyle">10. Compatibility with your network and lifestyle</h2>
At the end of the day, your personal preferences are the leading factor in determining what features you need in your phone. Make sure your device is compatible with your carrier’s network and bands (e.g. 5G).
Be sure to consider other coverage features. For instance, if you travel often or use your phone for both personal and work reasons, you might want Dual SIM or eSIM support, which lets you use and switch between two phone numbers.
Or if you consistently connect your other devices to your phone’s wireless network, you’ll want built-in mobile hotspot support.
<h2 id="choose-the-right-phone-features-for-your-lifestyle">Choose the right phone features for your lifestyle</h2>
The cell phone features you need ultimately depend on your preferences and lifestyle. You might care most about screen size, screen responsiveness, storage space, or ruggedness.

Must-have cell phone features

With everything you can do on your smartphone­­­­­­­­­—<a href="https://www.att.com/blog/how-to-manage-personal-finances-with-tech" target="_blank" rel="noopener">manage your finances</a>, schedule appointments, and share files—think about all the sensitive data it holds. So, how can you protect data on a mobile device?
If your phone falls into the wrong hands, you could face:
<ul>
<li>Being locked out of your accounts</li>
<li>Having your identity stolen</li>
<li>Your sensitive information being used against you</li>
</ul>
Safeguard your sensitive data from getting into the wrong hands by creating strong passwords, using biometrics, installing a trusted security app, and more. These simple steps don’t take much time—and can save you time, money, and hassle.
<h2 id="importance-of-data-protection-on-mobile-devices">Importance of data protection on mobile devices</h2>
Our <a href="https://www.att.com/buy/phones/" target="_blank" rel="noopener">phones</a> have become our 24/7 companions, which means you likely have your whole life stored on your device. Your phone holds sensitive information like:
<ul>
<li>Messages to friends and family</li>
<li>Emails and professional communications</li>
<li>Financial documents</li>
<li>Photos and videos</li>
</ul>
You’ll want to keep it all protected because if your information gets exposed, a bad actor could:
<ul>
<li>Open credit cards, bank accounts, or home and auto loans in your name</li>
<li>Steal your social media, email, and other accounts</li>
<li>Impersonate you online</li>
<li>Use private information against you</li>
</ul>
While phone manufacturers constantly create new safeguards to make their devices more secure, hackers are getting better at bypassing them. To keep your data protected, it helps to be proactive.
<h2 id="set-strong-passwords-and-enable-biometric-authentication">Set strong passwords and enable biometric authentication</h2>
Start by using unique, strong passwords for your accounts and your phone’s lock screen. Be sure not to use easy-to-guess passwords like 1234 or 1111 that make it easier for someone to get into your phone.
Choose a long password that’s at least 12+ characters. Also, use a combination of letters, numbers, and special characters to enhance your overall security.
Consider passphrases, words or phrases that are difficult to guess. They tend to be more secure than passwords since they’re typically longer and more complex.
Even with the strongest password or passphrase, don’t reuse them for multiple accounts. This can leave you vulnerable during data breaches. If a cybercriminal gets access to one account, they can use the same password for your other accounts.
On top of passwords, lock your phone and apps with biometrics like facial recognition and fingerprint scans. These add an extra layer of security to your phone.
<h3 id="facial-recognition">Facial recognition</h3>
Instead of typing a password or PIN, use facial recognition to unlock your device, handle payments, or open certain apps. Since your face is so unique, it’s harder for a scammer to copy and use to access your device and data.
<h3 id="fingerprint-scans">Fingerprint scans</h3>
Fingerprints are unique to you and are usually difficult to mimic. For extra protection, pair biometrics with a strong passcode.
Biometrics are among the most effective mobile device security features currently available. They’re also convenient and can be used with other authentication measures to better protect your data.
<h2 id="use-multi-factor-authentication-mfa-wherever-possible">Use multi-factor authentication (MFA) wherever possible</h2>
Multi-factor authentication (MFA) uses two or more verification steps to protect your accounts. This can include a combination of several security features, like:
<ul>
<li>Passwords</li>
<li>Prompts on verified devices</li>
<li>One-Time Passwords (OTPs) sent via text to your registered number</li>
<li>Facial recognition</li>
<li>Fingerprint scans</li>
<li>Security questions</li>
<li>PINs</li>
</ul>
MFA helps because a password alone isn’t enough—a stranger would also need access to your device or a second verification step. MFA is an essential privacy measure for sensitive apps and anywhere you keep personal data, such as cloud storage services.
Even with MFA, consider other ways to keep your phone locked and private from others.
<h2 id="enable-your-devices-auto-lock-and-screen-privacy-settings">Enable your device’s auto-lock and screen privacy settings</h2>
When you’re out in public, it’s easy to set your phone down and forget about it for a while. If it’s unlocked, you’ve given strangers free access to your device and its information.
Set a short screen timeout that locks your phone when you’re not using it. Once your phone is locked, someone will need your password, face, fingerprint, or some other security measure to breach your device.
Shoulder surfing—when someone secretly looks at your screen to obtain passwords or other information—can also be a major concern in public spaces. Use a privacy <a href="https://www.att.com/buy/accessories/browse/screen-protectors/" target="_blank" rel="noopener">screen protector</a> to shield your data by obscuring your screen when viewed at an angle.
In some cases, others are helping to secure your device without you having to do anything at all.
<h2 id="keep-your-operating-system-and-apps-up-to-date">Keep your operating system and apps up to date</h2>
Developers are constantly searching for security loopholes in their code and patching them via updates. That makes the latest versions of operating systems (OSs) and apps safer than ever. These updates address issues like bugs, weak spots in older software, and add more advanced security features.
To enable automatic updates, look for the Software Updates or App Updates in Settings and toggle them on. When it’s time for an update, your phone will automatically take care of it.
For extra security, you can turn to trusted security apps to keep your phone as safe as possible.
<h2 id="use-a-trusted-mobile-security-app">Use a trusted mobile security app</h2>
The right <a href="https://www.att.com/blog/what-is-the-att-activearmorsm-mobile-security-app" target="_blank" rel="noopener">mobile security app</a> can protect your phone from an array of online and offline threats. Choose an app with key features like:
<ul>
<li>Malware scanning to search for and eliminate unauthorized software on your device</li>
<li>Theft protection to lock or return your phone if it’s stolen</li>
<li>Tracking services to find your device if it’s taken or lost</li>
<li>Phishing and scam security measures to protect you against bad actors</li>
</ul>
Pick a trusted mobile security app with a solid track record. Avoid apps that overpromise and offer little protection. And those threats are lurking everywhere, whether you’re at home or out and about.
<h2 id="protect-your-data-on-public-wi-fi">Protect your data on public Wi-Fi</h2>
When you’re away from your home network, you still need to be able to access the internet. Public Wi-Fi is convenient, but it can pose serious cell phone security risks. Other individuals may be able to see your activity on public networks and capture information you view, send, or log into. Hackers can also set up fake “free Wi-Fi” networks.
<h3 id="vulnerable-public-wi-fi-examples">Vulnerable public Wi-Fi examples</h3>
Vulnerable public networks exist anywhere there’s Wi-Fi and crowds, such as airports, restaurants, hotels, and other crowded places.
Be wary of networks in these places and, if they seem suspicious, use your mobile data instead of risking your personal information. Follow key internet security tips, like using a <a href="https://www.att.com/blog/benefits-of-vpns" target="_blank" rel="noopener">Virtual Private Network</a> (VPN) to help encrypt your traffic on that network.
Because a VPN encrypts your connection, your data is less accessible and more secure.
<h3 id="protect-your-personal-hotspot-with-a-strong-password-and-vpn">Protect your personal hotspot with a strong password and VPN</h3>
Even if you use a <a href="https://www.att.com/buy/connected-devices-and-more/" target="_blank" rel="noopener">mobile hotspot</a>, hackers may be able to see your internet activity if they gain access to it. Set a lengthy, strong password to prevent unauthorized users from connecting, or use a passphrase. Change it regularly. Also, consider using a VPN when using your hotspot in public for extra protection.
Another way to protect your data is to use encryption tools to ensure it doesn’t get into the wrong hands.
<h2 id="encrypt-your-device-and-stored-data">Encrypt your device and stored data</h2>
Encryption helps keep your device and its contents safe by converting data (like emails and text messages) into unreadable code. A key is needed to convert the code back into readable data.
Most newer phones come with built-in encryption capabilities. They scramble your data to ensure that only the person with the correct password, passphrase, or biometric information can unlock and unscramble the data. Set a screen lock to make encryption more effective at protecting your data.
Even with the best practices, you still need to regularly back up your data to keep your information protected.
<h2 id="back-up-data-regularly-and-securely">Back up data regularly and securely</h2>
Using <a href="https://www.att.com/features/att-personal-cloud/" target="_blank" rel="noopener">cloud storage</a> lets you save what’s important to you on a remote server instead of locally on your phone. If your phone is ever lost, stolen, <a href="https://www.att.com/blog/how-to-replace-a-broken-phone-making-the-best-of-a-bad-situation" target="_blank" rel="noopener">damaged</a>, or compromised, you can still access your memories and pertinent information.
Turn on automatic backups for your photos, videos, documents, and other files to protect your data. If you lose your phone, access your saved files by logging into your cloud account on another device.
And if you can’t recover your phone, there are other important steps to take.
<h2 id="set-up-remote-lock-and-wipe-features">Set up remote lock and wipe features</h2>
If your phone is stolen but has a lock screen passcode, the thief may try to guess a way in. To stop them, follow this <a href="https://www.att.com/blog/dont-panic-a-lost-phone-checklist" target="_blank" rel="noopener">lost phone checklist</a> to:
<ul>
<li>Temporarily lock login attempts after multiple wrong passwords</li>
<li>Increase the lockout time with continued failed attempts</li>
<li>Erase data after too many tries (if your device supports it)</li>
</ul>
Turn these features on in your phone’s security settings to protect your data in case you can’t recover your device.
Keep in mind that protecting your data and phone is an ongoing process that you must constantly keep an eye on.
