This article helps you troubleshoot low internal memory issues on your CAT S48c

You may have low internal memory issues if your phone is:

• Displaying low memory error messages
• Unable to install applications
• Freezing or unresponsive

These steps help identify and resolve the underlying cause. After completing each step, test to see if the issue is fixed. If not, continue to the next step.

Low memory issues can arise when you have too many applications on your CAT S48c or when you need to clear your application cache.

1. Determine if your phone has low memory.
   
1. From the home screen, swipe down the Status bar.
2. Tap the Settings icon.
3. Tap Storage.
4. Refer to the Storage used section to determine if your phone has low memory.


2. Uninstall unused applications.

   Sprint recommends that you uninstall unused applications when possible. It helps free up internal memory and can improve device performance.

   Uninstall an application.

   Note: Your CAT S48c comes with some pre-installed applications that you can't uninstall.

3. Move applications to the memory card.

   By default, your CAT S48c saves all applications to internal memory. To free up internal memory, you can move some applications to the memory card.

   Note: Be sure your memory card has enough space to handle the transfer. You can also consider switching to a higher capacity memory card. Some applications must remain on internal memory. If an application on the memory card malfunctions, move it back to your CAT S48c internal memory.

   1. From the home screen, swipe down the Status bar.
   2. Tap the Settings icon.
   3. Scroll to and tap Apps & notifications.
   4. Tap See all apps.
   5. Scroll to and tap the preferred application.
   6. Tap Storage.
   7. Tap CHANGE.
   8. Tap the SD card name.
   9. Tap MOVE.

4. Clear application cache.

   Each application has a cache of temporary files that may be taking up memory. Try clearing the application cache from your larger applications to free up space. Continue to clear the cache on the rest of your apps. You may not be able to clear the cache for every application. Rarely, an application may not function as expected afterward. Be sure you clear only the application cache and not the application data.

   If you clear the application data, you remove your personal settings and info such as login information and high scores. If you clear the application cache, you don't remove your personal settings or information.

   Clear the application cache.

5. Perform a soft reset.

   A soft reset deletes any temporary files and can potentially free up internal memory.

   1. Turn the device off by pressing the Power/Lock key.
   2. Tap Power off.
   3. Wait 10 seconds.
   4. Turn the phone back on.

Note:To optimize device performance, be sure your CAT S48c is running the most recent device software. Check for software updates.
