    Clear App Cache/Data:

    NOTE: If one of your apps doesn’t work as intended, crashes, freezes, 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 app data stored within the app will be removed, including login and credit card information, settings, user profiles, save files etc. To avoid losing personal app data, clear ONLY the app’s cache.

    1. Go to “Settings
    2. Access “Apps
    3. Select the desired app
    4. Tap “Storage
    5. Tap “Clear cache” to clear the app’s cache
    6. If this didn’t solve the issues, try tapping “Clear data” (check WARNING above)

    Wipe the Cache Partition:

    NOTE: If your device crashes, freezes, or 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 problems by clearing the phone’s cache partition. This can solve the issues like a factory reset, without losing personal data stored on the phone’s memory.

    1. Turn the device off
    2. Press and hold “Home” and “Volume Up” at the same time, then press and hold “Power” too
    3. At the Android screen, release the buttons and wait to gain access to Android Recovery
    4. Once in Recovery, 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” and press “Power
    7. Highlight “Yes” and press “Power” again
    8. Once done, ensure “Reboot system now” is highlighted and press “Power

    NOTE: If clearing the cache didn’t help, you can visit this thread for instructions on how to factory reset the phone instead.

    Reboot to Safe Mode and Remove an App:

    NOTE: If you have installed a third-party app that causes problems and prevents you from removing it, you should be able to uninstall the app from within Safe Mode. In this mode, all third-party apps are disabled by default.

    1. Disable the phone
    2. Press and hold “Power” past the model name screen
    3. At the Samsung logo, release “Power” and quickly press and hold “Volume down” instead
    4. Once the phone finishes rebooting, release all the buttons. A Safe Mode watermark should be visible in the lower area of the home screen
    5. To uninstall an app, first open “Settings
    6. Then go to “Apps
    7. Select the desired app and tap “Uninstall
    8. Once done, exit Safe Mode by rebooting your device as you would do normally, by pressing and holding “Power
