Fix an installed Android app that isn't working

If an app installed on your Android device is crashing, or won't open, respond, or work properly, try the troubleshooting steps below. After trying each, check whether it fixed your issue.

If a Google app that came with your device seems to have problems, those problems could be caused by another app later downloaded to your device.

Tip: If the app that isn’t working is an Instant App, try these troubleshooting steps instead.

Note: Some of these steps work only on Android 8.1 and up. Learn how to check your Android version.

Step 1: Restart & update

Restart your device

To restart your phone, press and hold the power button for a few seconds. Then, on your screen, tap Restart Restart.

If you don't see "Restart," press and hold the power button for about 30 seconds, until your phone 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 app.
  2. Near the bottom, tap System and then System updates. If needed, first tap About phone or About tablet.
  3. You'll see your update status. Follow any on-screen steps.

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.

Force stop the app

Clear the app's cache

Clearing cached data can free up needed space by removing temporary files. This is a short-term solution. Over time, cached data will build up again.

  2. Tap Apps & notifications.
  3. Tap the app. If you don't see it, first tap See all apps or App info.
