1. Force reboot your phone

Before trying anything else, try performing force reboot of your phone and see if the booting issue resolves. This action is like having battery removed from your phone for it to shut down and restart. Most often, this can fix most smartphone problems including booting issue.

  • When the device logo appears, release both keys and wait until the device restarts

If the phone is still unable to boot after doing this, then proceed on to the next solution.

Safe mode is an alternative booting option you can use on your smartphone. It helps you to identify and understand issues with your device. The safe mode basically works by temporary disabling all third-party apps and running only native applications on your device.

  • Safe mode will show in the bottom left corner of the screen
  • Release the Volume down key when you see Safe mode
