Troubleshoot issues related to low internal memory on your HTC EVO 4G

Last Updated: Apr 09, 2013

This article helps you troubleshoot low internal memory issues on your HTC EVO 4G.

You may have low internal memory issues if your device 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 arise when you have too many applications on your HTC EVO(TM) 4G or when you need to clear your application cache.

  1. Verify you have available memory using Sprint Zone.

    The Sprint Zone application can help identify the cause of low memory issues.

    1. Access Sprint Zone.
    2. Tap Help.
    3. Tap I Need Help.
    4. Tap More Diagnostics.
    5. Scroll down to Other Diagnostics to view information on Memory and Internal Device Storage.
    6. Tap Memory to view applications and processes that are currently consuming system memory and storage.
    7. Try closing an application, and if you no longer use an application, uninstall it.
    8. Test your device to see if the issue is resolved.

  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 HTC EVO 4G comes with some pre-installed applications that you can't uninstall.

  3. Move applications to the memory card.

    By default, your HTC EVO 4G 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.

    Move an application to the memory card.

    Note: Some applications must remain on internal memory. If an application on the memory card malfunctions, move it back to your HTC EVO 4G internal memory.

  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. Press and hold the Power key, and then tap Power off to turn your HTC EVO 4G off.
    2. Remove the battery. After 30 seconds, reinsert the battery.
    3. Press and hold the Power key to turn your HTC EVO 4G back on.
    4. Test your device to see if the issue is resolved.

Note: To optimize device performance, be sure your HTC EVO 4G is running the most recent device software. Check for software updates.
