Fix an Android device that won't start or turn on

If your Android phone or tablet isn't starting, won't turn on, has a black or blank screen, or turns on but immediately turns off, try these steps to fix the issue.

First, try holding down your device's power button for 5-7 seconds. This usually restarts a device.

Step 1: Troubleshoot your cable, charger, outlet & case

  1. Use the charger and cable that came with your device. To check that the charger and cable are working, try them with another device.
  2. Check that the cable is securely connected to the charger and to your device. Check that there's nothing in your device's port, like dust or lint.
  3. Plug the charger into a wall outlet. To check that the outlet is working, plug in something else, like a lamp.
  4. Check that no accessories, like cases or battery packs, cover your device's sensors or press its buttons.

Step 2: Troubleshoot your battery charge

Within 1 minute after you've plugged in your Android device with a working cable, charger, and outlet:

  • If you see a battery icon, your device is powered off and is charging. You can restart right away.
  • If you see a red light, your battery is fully discharged. If the red light is flashing, there isn't enough power to turn on. Charge your device for at least 30 minutes before restarting.

To restart your device, press and hold the power button for a few seconds. Then, on your screen, tap Restart Restart. (If you don't see "Restart," press and hold the power button for about 30 seconds, until your device restarts.)

Note: Battery icons and lights can vary by device. For your device's details, contact your device manufacturer.

Step 3: Troubleshoot your screen

If you don't see a battery icon or red light after you plug in your Android device, the issue could be with your screen. If the device can get calls:

  1. Press the power button for about 30 seconds.
  2. Wait about 2 minutes.
  3. Make your device ring. You can call it from another phone or use Find My Device. Learn how.
  4. If your device rings, learn how to troubleshoot your screen.

Step 4: Troubleshoot with advanced steps

Option 1: Troubleshoot by connecting to a computer
  1. Unplug the cable from the power charger.
  2. Check that your computer is on and connected to a power source.
  3. Connect your Android device to your computer's USB port with the cable that came with your device.
  4. Wait 10–15 minutes.
  5. Disconnect and reconnect the cable from your device within 10 seconds.
  6. Within 1 minute:
    • If you see a battery icon, your device is powered off and is charging.
    • If you see a red light, your battery is fully discharged. If the red light is flashing, there isn't enough power to turn on.
  7. Charge your device for at least 30 minutes.
  8. Press and hold the power button for a few seconds.
  9. On your screen, tap Restart Restart. If you don't see "Restart," press and hold the power button for about 30 seconds, until your device restarts.

Note: Battery icons and lights can vary by device. For your device's details, contact your device manufacturer.

Option 2: Troubleshoot using your device's buttons

With your device plugged in, press and hold both the volume-down button and the power button at the same time for at least 20 seconds.

  • If you see a red light, your battery is fully discharged.

    1. Charge your device for at least 30 minutes.
    2. Press and hold the power button for a few seconds.
    3. On your screen, tap Restart Restart.
  • If you see an Android robot and the word "Start" with an arrow around it:

    1. Press the volume-down button until you see the option to "Power off." Press the power button to pick "Power off."
    2. Charge your device for at least 30 minutes. 
    3. Press and hold the power button for a few seconds.
    4. On your screen, tap Restart Restart. If you don't see "Restart," press and hold the power button for about 30 seconds, until your device restarts.

Note: Battery icons and lights can vary by device. For your device's details, contact your device manufacturer.
