See if an app is causing the problem

If your problem goes away in safe mode

A downloaded app is likely causing your problem. To see which app it is:

  1. Restart your phone.
  2. One by one, remove recently downloaded apps. Learn how to delete apps. After each removal, restart your phone normally. See whether removing that app solved the problem.
  3. After you remove the app that caused the problem, you can add back the other apps that you removed. Learn how to reinstall apps.

Still having slowness issues?

Consider resetting your phone to factory settings

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

IMPORTANT: A factory data reset will remove all data from your phone. 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, we recommend backing up your phone.

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