Troubleshoot a device that restarts on its own or crashes

If your device keeps rebooting itself, or crashing without restarting, one of the steps below may fix the issue. After following the steps for each recommended solution, check whether it fixed your issue.

Restarting constantly? Your device may be stuck in a "boot loop." Skip to "Still having restart issues?" below.

Note: Android isn't the same on all devices. These instructions are for devices running Android 6.0 and up. Learn how to check your Android version.

Troubleshoot your device for random restarts

Check for Android updates

System updates can bring improvements that may fix your issue.

To check for and install system updates:

  1. Open your device's Settings app Settings.
  2. Scroll to the bottom and tap About phone or About tablet and then System updates.
  3. You'll see your update status. Follow any on-screen steps.
Check storage & clear space

You may see issues if your device's internal storage is full or almost full. To free up space that your device needs to work properly, you can remove unnecessary files and clear cached data.

To check how much storage your device has:

  1. Open your device's Settings app Settings.
  2. Under "Device," tap Storage.
  3. See how much storage you have available. Your device can start having issues when less than 10% of storage is free.

If you're running low on storage, learn how to save space with automatic storage and deletion and manage storage and memory.

Troubleshoot apps on your device for random restarts

Check for app updates

App updates can bring improvements that may fix your issue.

To see and get updates for your apps:

  1. Open your device's Play Store app Google Play.
  2. Tap Menu Menu and then My apps & games.
  3. Apps with available updates are labeled "Update."
    • If an update is available, tap the app and then Update.
    • If multiple updates are available, tap Update all.
Close apps you're not using

In general, you don't need to close apps. Android automatically manages the memory that apps use.

But to completely shut down an app, including any background services that it may be using:

  1. Open your device's Settings app Settings.
  2. Tap Apps.
  3. Pick the app from the list.
  4. Tap Force stop.

Tip: To help identify apps that cause problems, make a list of which apps you force stop.

See if an app is causing the problem

The problem could be caused by an app that you downloaded. To see whether a downloaded app is causing the problem, you can restart your device in safe mode.

Safe mode temporarily turns off all downloaded apps.

To restart in safe mode:

  1. Turn on safe mode. Learn how.
  2. After you're in safe mode, wait to see if the problem goes away.

If your problem doesn't go away in safe mode

Restart your device and skip to the next section.

If your problem goes away in safe mode

A downloaded app is most likely causing your issue. To find out which app it is:

  1. To exit safe mode, restart your device.
  2. One by one, uninstall recently downloaded apps. After each removal, restart your device. See whether removing that app solved the problem.
  3. After you remove the app that's causing the problem, you can reinstall the other apps that you removed.

Still having restart issues?

If your device still restarts itself after trying all the common solutions above, you may want to try these advanced troubleshooting steps.

Remove cases and external batteries

If you’ve put a third-party case, external battery pack, or other accessory on your phone, try taking it off during troubleshooting.

Make sure that external accessories don’t cover your phone’s sensors or touch its buttons.

Consider resetting your device to factory settings

To remove any processes on your device that may be causing the issue, you can reset your device to factory settings.

IMPORTANT: A factory data reset will remove all data from your device. While any data stored in your Google Account will be restored, all apps and their associated data will be uninstalled. Before you perform a factory data reset, learn how to back up and restore data on a Pixel phone or Nexus device.

If an app that you downloaded caused the issue and you reinstall that app, the problem could come back.

Learn how to perform a factory data reset.
