If your phone has not been exposed to physical or liquid damage, the problem might be due to software glitch and this can be fixed on your end. First, charge your phone to make sure that it has enough battery life. After charging your phone, soft reset it. To do so, press and hold the volume key for at least 45 seconds, then wait until your phone restarts. But, if the black screen problem started after you downloaded an app, then it is also possible that the downloaded app has caused the phone to be stuck on black screen. This can be corrected by starting your phone in Safe Mode. Starting your phone in Safe Mode will only allow pre-installed apps to run while the phone is on. If the problem is corrected after starting your phone in safe mode, then the app has caused the issue to arise. Being said, you need to find out what this app is and have it uninstalled.
