  • Clean the charging port of the phone using a can of compressed air. Make sure that any dirt or debris stuck in this port is removed.
  • Fully charge the phone using its wall charger.
  • In case the phone does not charge then try using a different charging cord and wall charger. You should also try charging the phone from a computer USB port in case charging using the wall charger fails to work.

Once the phone has sufficient charge you should try turning on the device.

Most issues such as this can usually be fixed by doing a soft reset. This is usually the first thing you will have to do when the phone is unresponsive however this will also work in this case as it will refresh the phone software. This is done by pressing and holding on the power button for a few seconds until the device restarts.

Check if the problem occurs in Safe Mode

There are instances when an app you downloaded can cause this particular problem. To check if this is the case you will have to start the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.

  • Make sure that the device is off.
  • Press and hold the Power key past the screen with the device name.
  • When ‘SAMSUNG’ appears on the screen, release the Power key.

  • Safe mode will display in the bottom left corner of the screen.

Wipe the cache partition of the phone

There are cases when the temporary data of the phone software can get corrupted which can result to issues occurring on the device. The best thing to do in this scenario is to wipe the cache partition of the phone from the recovery mode.

Perform a factory reset

One last troubleshooting step to consider is a factory reset. This will revert the phone back to its original factory condition and will usually fix the problem in case is is caused by a software glitch. Take note that this will erase your phone data.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Home key, then press and hold the Power key.
