Keep your tablet's Android version and security patch current

Android tablets receive periodic OS upgrades and monthly-ish security patches that fix vulnerabilities, improve battery behavior, and add new multitasking or One UI features.

What you should know

  • Found under Settings > Software update (One UI) or Settings > System > System update on stock Android.
  • Tap Download and install to check for and apply a pending update; tablets typically need at least 50% battery or to be plugged in.
  • Security patch level and Android version are listed on the same screen under About tablet > Software information.
  • Larger tablets often lag behind phones by a few weeks for the same OS version, since updates are staged per device model.

Keep the tablet connected to Wi-Fi and plugged in during installation — interrupting a system update partway through can leave the device stuck in a boot loop.

Why it matters

Security patches close vulnerabilities that can be exploited over Wi-Fi or through malicious apps, and many app updates eventually require a minimum Android version — falling behind can silently break app compatibility.

Best practices

  • Turn on automatic system updates in Settings > Software update > Download updates automatically so patches install overnight.
  • Back up important data before a major Android version upgrade (not just monthly patches), since a full version jump changes more system behavior.
  • Check available storage before updating — large OS upgrades can need several gigabytes of free space to download and stage.

Common problems and fixes

Update download stalls or fails repeatedly
Switch to a different Wi-Fi network, clear the cache for the Software Update / Google Play services app under Settings > Apps, then retry.
"Not enough storage" message when checking for updates
Free up space under Settings > Battery and device care > Storage (or Settings > Storage) by removing downloaded files, offline video, or unused apps.

Tips and tricks

  • Updates queued overnight while charging on Wi-Fi install automatically on most tablets if "Auto restart at scheduled time" is enabled in the same Software update menu.

Frequently asked questions

Will updating erase my apps and files?

No, a normal system update preserves your apps and data — only a factory reset removes them.
