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 recommended solution, check to see 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.

Step 1: Restart and 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.
  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.
Update the app

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 Play Store.
  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.

Step 2: Check for a larger app issue

Force stop the app

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.

If you continue to have the same problems with the app after you've force stopped, you may need to contact the app's developer. Learn how to contact a developer.

Clear the app's cache

Clearing cached data can free up needed space by removing temporary files from your device. This is a short-term solution; over time, cached data will build up again and will need to be cleared.

To clear the cache for the app:

  1. Open your device's Settings app Settings.
  2. Tap Apps or Application manager (depending on your device).
  3. On the list, tap the app.
  4. Tap Storage.
  5. Tap Clear cache.

If you continue to have the same problems with the app after you've cleared its cache, you may need to contact the app's developer. Learn how to contact a developer.
