Last Updated: Nov 18, 2014

This article helps troubleshoot your LG G2 slowing, freezing, or turning off unexpectedly.

You may have performance issues if your LG G2™:

  • Performs slowly
  • Freezes
  • Turns off or unexpectedly restarts
  • Displays error messages
  • Is unable to install or update applications

Try each of these steps to see if it helps improve your phone's performance.

  1. Perform a soft reset.

    A soft reset restarts your phone and does not erase any of your content or data.

    1. Press and hold the Power key until your phone restarts.
  2. Use Sprint Zone to determine if your phone has low memory.

    1. Access Sprint Zone.
    2. Swipe from Right to Left to open Device Diagnostics.
    3. Tap Storage.
    4. Refer to Available in the Overview section to determine if your phone has low memory.
  3. Clear the application cache.

    • Clear the application cache on your applications to free up space and improve performance.
    • Be sure you clear only the application cache and not the application data.
    • When you clear the application data, it removes your personal settings and info such as login information and high scores.
    • Clearing the application cache doesn't remove your personal settings or information.

    1. From the home screen, tap the Menu key.
    2. Tap System settings.
    3. Scroll to and tap Apps.
    4. Swipe to the All tab.
    5. Scroll to and tap the preferred application.
    6. Tap Clear cache.
    7. You've now cleared the application cache.
  4. Close or uninstall applications.

    • Some apps run in the background when you are not using them.
    • Also, some apps consume more energy than others.
    • Some apps come pre-loaded on your phone and you can't uninstall them.

    1. From Device Diagnostics, tap Power Usage.
    2. Tap Battery Usage.
    3. Tap the application you want to close or uninstall.
      • Close (turn off) an application: Tap Force stop.
      • Uninstall (remove from phone) an application: Tap App info, Uninstall, and then OK.
  5. Verify that your LG G2 is running the most recent software.

    1. From Device Diagnostics, tap System Updates.
    2. Tap Device Software.
    3. Tap Check now.
      • If an update is available, follow the prompts to install.
