How to fix the Android Black Screen of Death

If you’ve ever had your Android phone go unresponsive or
black on you while in use (and still on) then this is one
variant of the Android black screen of death (different from
when the Android phone is bricked and totally dead). In
this very scenario we’ll be discussing, you’ll see lights on the
soft keys (Home, Menu and Back) which indicates that the
phone is still on but the screen will be totally black, no key
or buttons responding.


What could cause the Android Black Screen of Death?


This error usually points at a slow, hanging or lagging
android (see http://www.gistpluz.com/2015/06/how-to-easily-make-android-phone-run.html?m=1 ) so
you might want to consider the following:



Launcher problems: The launcher in use might be
experiencing some problems


Buggy applications: Some apps might be encountering
errors or have used up the phone’s resources


Screen protector / guard: If these interfere with the
phone’s sensors then this could be a problem


How do I fix the Android black screen of death?

If you have such an issue on your hands then try the
following:


Leave the phone for about 30 seconds then try waking it
up with the power button


Remove the battery for 20 seconds then slot back in and
power up the phone

Uninstall any recently installed / suspicious apps

If the phone is running or a third party launcher, revert
to stock launcher or use another

Remove any casing, screen guard or protector

If all of the above don’t work then boot into recovery
mode and do a factory reset


Flash the stock ROM if a factory reset doesn’t help
