Clearing the App Cache:

NOTE: Assuming that one of your applications is not working as intended, it crashes / freezes etc. then you could be able and fix these problems by clearing the app's data and / or cache.

WARNING! Keep in mind that clearing an app's data will result in the deletion of all personal data stored in the app. This includes settings, user information, high scores, profiles, credit card information etc.

NOTE: Clearing an app's cache will not delete any personal data, so it's highly recommended that you try fixing the issues by clearing the cache first, before going through with data clearing. To do so:

1. Tap the "Apps" icon while on a home screen
2. Tap "Settings" > "More"
3. Tap "Application manager" and access the "All" tab
4. Select the desired app and tap "Clear cache" > "OK"
5. If the process has not fixed the issue(s) with the app, tap "Clear data" > "OK"

Clearing the Cache Partition:

NOTE: Assuming that your phone is not working correctly and you're considering applying a master reset in order to fix these issues, you should try solving the problems by clearing the cache partition first. Unlike a factory reset, clearing the cache will not result in the deletion of personal data stored on the phone's internal memory. To wipe the cache:

1. Turn off the smartphone
2. Press and hold the "Home", "Power" and "Volume Up" buttons at the same time
3. Once the phone vibrates once, release the "Power" key but continue pressing the other two physical buttons
4. Once the "Android System Recovery" screen appears, release all the hardware keys
5. Press the "Volume Down" button to navigate to, and highlight "wipe cache partition"
6. Select the highlighted option by pressing "Power"
7. Once the cache partition has been wiped, the "Reboot system now" option will be highlighted
8. Press "Power" to reboot your device

NOTE: If clearing the phone's cache partition has not helped with solving the issue, you may want to apply a master reset. To learn how you can factory reset the Samsung Galaxy K Zoom, visit this link for a full guide.
