Clear App Cache/Data:

NOTE: In case one of your apps doesn’t work as intended or takes up too much storage inexplicably, you can try fixing these issues by clearing the app’s cache and/or data.

WARNING! When you clear an app’s data, all your personal data stored within the app will be deleted, including settings, user profiles, high scores, save files, credit card and login information etc. To avoid losing personal app data, clear ONLY the app’s cache.

  1. Open the apps drawer
  2. Open “Settings
  3. Tap “Apps” and select the desired app
  4. Go to “Storage” and tap “Clear cache
  5. If clearing the cache didn’t help, tap “Clear data” (check WARNING above)

Wipe the Cache Partition:

NOTE: If your phone freezes, crashes, runs out of storage inexplicably or otherwise doesn’t work as intended and you’re considering factory resetting it, alternatively you can try fixing these issues by clearing the phone’s cache partition. This can lead to results similar to a factory reset without losing any personal data stored on the device.

  1. First ensure the phone is powered off
  2. Next, press and hold “Home” and “Volume Up” at the same time, then press and hold “Power” too
  3. At the “Android” logo, release all buttons and wait up to a minute to gain access to Android System Recovery
  4. In the Recovery menu, press “volume down” repeatedly to highlight “wipe data / factory reset
  5. Press “Power” to select the highlighted option
  6. Press “Volume down” to highlight “wipe cache partition
  7. Press “power” to confirm
  8. Use “Volume down” to highlight “Yes” and press “Power
  9. Once the cache partition is wiped, highlight “Reboot system now” and press “Power

NOTE: If clearing the cache partition didn’t solve the problems, you can check this thread for a guide on how to factory reset the device instead.

Reboot to Safe Mode and Remove an App:

NOTE: If you have installed a third party app that causes issues and prevents you from removing it, you can try removing the app from Safe Mode. In this mode, all third party apps are turned Off.

  1. First turn the phone Off
  2. Press and hold “Power” past the model name screen
  3. At the “Samsung” logo, release “Power” and immediately press and hold “Volume down” instead
  4. After the phone finishes rebooting, release “Volume down”. NOTE: a “Safe Mode” watermark should be shown in the lower area of the home screen
  5. To remove an app, open “Settings” and go to “Apps
  6. Then select the desired app and tap “Uninstall
  7. To exit Safe Mode, press and hold “Power” and tap “Restart” to confirm
