Clear App Cache/Data:

NOTE: If one of your apps doesn’t work as intended, freezes, crashes, takes up too much storage inexplicably etc. you can try solving these problems by clearing the application’s cache or data.

WARNING! When you clear an app’s data, all your personal app data stored within the application will be deleted. This includes login details, user profiles, save files, settings etc. To avoid losing personal app data, clear ONLY the app’s cache.

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

Clear 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 resetting it, alternatively you can try fixing these issues by clearing the cache partition. This can lead to the same results as a factory reset without losing personal data located on the phone.

  1. Turn the phone OFF if necessary
  2. Next, press and hold “Volume UP” and “Home” at the same time, then press and hold “Power” as well
  3. When the Android screen appears, release the buttons and wait for access to the Recovery menu
  4. Then, navigate the menu by pressing “Volume down” repeatedly and 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
  8. Then highlight “Yes” and press “Power” again to confirm
  9. Once the process completes, highlight “Reboot system now” and select the option

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

Reboot to Safe Mode and Uninstall an App:

NOTE: In case you have installed a third-party app that causes issues and prevents you from uninstalling it, you should be able to remove the app from the phone while in Safe Mode, where all third-party apps are disabled by default.

  2. Then press and hold “Power” past the model name screen
  3. At the Samsung screen, release “Power” and quickly press and hold “Volume down” instead
  4. After the phone finishes rebooting, release all the buttons and you should be able to see a “Safe Mode” watermark in the lower area of the screen
  5. To remove an app from the phone, first open “Settings
  6. Go to “Apps” and select the desired app
  7. Tap “uninstall” and once done, exit Safe Mode by rebooting your device as you would do normally
