How to fix a Samsung Galaxy S21/21+ that is not turning on

If your phone doesn’t turn on, there are several things you can try.

It's all about the power

Before doing anything else, you must ensure that your phone has enough power. So, it is advisable to start by connecting the phone to a charger. You can leave it for a few minutes and then try to turn it on. It is best to use the original charger. If you are not using the one that came with your device, make sure you have a compatible charger.

Take some time to inspect the charging port. If you notice any dirt or debris, clean the dock and then charge your device. Make sure the cable and the charger are not damaged in any way.

Reboot and try again

The next thing you can try is the force reboot. This might solve the issue if the phone turns off due to a firmware crash. It is pretty simple. What you need to do here is press and hold the Volume down key and the Power key at the same time. Hold the buttons until the Samsung logo appears, and then release them.

If nothing changes, connect your phone to the charger and leave it for a few minutes. While the phone is still charging, perform a force reboot one more time.

Factory data reset

Before taking the phone to the Samsung Service Center, the last option is to do a factory reset using the hardware keys. It is time to repair or replace the device if that doesn't resolve the issue.

Keep in mind that factory data reset erases all data that is not backed up, so only proceed if you are okay with that.

To perform a factory data reset, follow the steps below:

  • First, press and hold the side buttons and the Volume up buttons at the same time
  • The smartphone should vibrate
  • Next, you will see the Android recovery screen
  • When the screen shows up, release the buttons
  • Navigate and select the option “Wipe Data/Factory reset” with Volume keys
  • Next, you will have to press the Side button to confirm the action
  • Again, use the Volume buttons to select the option "Yes" and the side key to proceed
  • Please wait for the factory reset to complete
  • Finally, select the option “Reboot System Now.”
