Troubleshoot when your LG G4 doesn't turn on

Last Updated: Aug 03, 2016

This article helps troubleshoot your LG G4 not turning on

You may have this issue if your LG G4™:

  • Doesn't turn on
  • Starts to turn on but restarts or shuts down before it turns on completely

Try each of these steps if your phone doesn't turn on.

  1. Verify that your LG G4 has a sufficient charge.

    1. Connect your original charger to your phone.
    2. After a few minutes, try to turn on your phone.
  2. Verify that your phone, charging port, and battery contacts are not damaged.

    1. Carefully inspect your phone to be sure it's not overheating, swollen or damaged.
    2. Carefully inspect your phone's charging port and remove any debris.
    3. Remove the battery.
    4. Carefully clean and inspect the gold contacts on both the battery and on your phone.

    Caution: If your phone is damaged, do not complete the remaining steps in this guide. Make an appointment at a convenient Sprint Repair center.

  3. Verify that you are using a compatible charger.

    You risk severe damage to your phone if the charger isn't the same voltage, amps, and plug type as your original charger. You can purchase compatible chargers on sprint.com and at any Sprint Store.

  4. Attempt a forced restart of the phone.

    Note: If performed correctly, a forced restart will not erase any information from the phone.

    1. Press and hold the Power key for 30 seconds.
      • If the phone starts to power on, release the Power key.

    If your LG G4 does turn on, verify that it is running the most recent software. Check for software updates.

  5. Attempt a hardware factory reset.

    Note: A hardware factory reset will erase ALL information on the phone! Any information that is not backed up online or to the SD card will be PERMANENTLY LOST.

    Perform a hardware factory reset.
