How to Update Tablet Firmware

Why firmware updates matter

Firmware updates deliver security patches, performance improvements, and bug fixes. On Android devices, the Android Open Source Project publishes security bulletins that detail vulnerabilities and the patches that address them. Installing updates as they appear helps keep your tablet protected against known threats. Updates also improve compatibility with apps and accessories, and they can extend battery life by optimizing power management.

Tablets are small, light multifunction devices with touch screens, as described by ENERGY STAR. Like any computer, they rely on software updates to remain secure and efficient over time. Always accept update notifications, or check manually on a regular schedule, such as once a month. For a broader look at operating system updates, see our article on tablet OS updates: Tablet Software Updates.

Check for updates on Samsung tablets

Samsung tablets run Android with One UI, Samsung's custom interface. To check for updates, open Settings, tap Software update, then tap Download and install. If an update is available, follow the on-screen instructions. You can also enable automatic downloads over Wi-Fi in this menu. Samsung recommends installing updates promptly to keep the device secure.

If your Samsung tablet is a Galaxy Tab model, the software update option resides in the same place. The exact name of the menu may vary slightly with older versions of One UI, but the path is consistent. If you are unsure, use the search function in Settings and type 'update'.

Check for updates on Lenovo tablets

Lenovo tablets run Android, often with a close-to-stock interface. Go to Settings, then System, then System update, and tap Check for updates. Lenovo may also push update notifications to your device. If you have a Windows-based Lenovo tablet, such as a ThinkPad, use Windows Update instead.

Lenovo provides updates both for its Android and Windows lines. The system update mechanism follows the same logic as other Android devices, so you can also look under Settings > About device > System updates. Keep an eye on the notification shade for update prompts.

Check for updates on Microsoft Surface tablets

Microsoft Surface tablets run Windows, not Android. Updates are delivered through Windows Update. Open Settings, then Update & Security, and click Check for updates. On newer versions of Windows, the path is Settings > Windows Update > Check for updates. Windows will download and install firmware and driver updates automatically when available.

Surface devices receive firmware updates that can improve battery life, display behavior, and hardware stability. Microsoft recommends keeping Windows Update enabled so that critical patches and optional firmware updates are installed promptly.

Prepare your tablet before updating

Firmware updates require a stable power source and adequate storage. Connect your tablet to a charger, especially if the battery is below 20 percent. The USB Power Delivery specification, maintained by the USB Implementers Forum, allows a single USB-C cable to carry both data and power, so using a certified charger that supports your device's power profile ensures a consistent power supply during the update process.

Back up important data before installing a major update. Though firmware updates rarely erase personal files, a corrupted download or interrupted installation can lead to data loss. Use the backup tools built into your operating system, or copy files to a computer or cloud service. You should also free up storage by deleting unused apps or files if the update requires additional space. For detailed backup guidance, see How to Back Up and Restore a Tablet.

Troubleshoot stuck or failed updates

If an update fails to install, first check your internet connection. A weak Wi-Fi signal can interrupt the download. Restart the tablet and try again. If the update continues to fail, boot into safe mode or recovery mode depending on the manufacturer, and clear the system cache if that option is available. For persistent problems, contact the manufacturer's support. See our guide on fixing a failed system update: Tablet System Update Failed.

After a successful update, give the tablet a few minutes to optimize apps and databases. If you notice battery drain or performance issues after an update, restart the device once more and check for additional updates. Some manufacturers release follow-up patches to address post-update issues.

Updates and device security

Firmware updates are a critical part of protecting your tablet from malware and exploits. The Android Open Source Project publishes security bulletins that list vulnerabilities and the patches that address them. When a manufacturer rolls out an update, it often includes these security patches, along with system improvements. Keeping your tablet current reduces your exposure to known threats. For more on security features, see Tablet Security Features.

For tablets used by children, updates are equally important. The Federal Trade Commission's Children's Online Privacy Protection Rule, or COPPA, gives parents control over what information websites can collect from their kids. While COPPA does not directly regulate firmware, regular updates help ensure that privacy protections and security controls stay current on devices used by kids. Always update a child's tablet as soon as a new version is available.

Check updates on other tablet brands

The steps above cover the three major ecosystems, but most tablet manufacturers follow a similar pattern. For any Android tablet from brands like Xiaomi, Blackview, or ONERugged, look in Settings for System or About Device, then find the Software update or System update option. On Fire tablets, updates are delivered through the Settings app under Device Options and System Updates. For Windows tablets, Windows Update is the universal path.

Regardless of brand, the principle is the same: keep the firmware up to date. If you are considering a new tablet, factor in the manufacturer's update track record. Some brands provide longer support windows than others. Check our buying guides to compare models: Best Android Tablets in 2026, Best Windows Tablets in 2026, or Best Samsung Tablets in 2026.

What to pick for your use

Questions

Will updating firmware erase my data?

In most cases, no. Firmware updates preserve your personal files and settings. However, a major version update could require more storage and reset some system optimizations. Always back up your data before updating to be safe.

How often should I check for updates?

Check manually on a regular schedule, such as once a month, and install updates as soon as the device prompts you. Security-critical patches are often bundled into monthly updates.

What if my tablet is too old to receive updates?

Older tablets may stop receiving updates when the manufacturer ends support. You can continue using the device, but it will be more vulnerable to security threats. Consider upgrading to a newer model if your device is several years old. See our Best Tablets Under $400 in 2026 guide for options.

Can I update without Wi-Fi?

Firmware updates are large and can consume mobile data. Most tablets allow updates over mobile data if you disable Wi-Fi, but it is not recommended. Use a stable Wi-Fi connection to avoid incomplete downloads.
