Screen is completing froze, won't power off! What shall we do?
This is on a Samsung Tablet
as a last resort you may have to reset it to the factory default, but only do this if it still stays frozen after 48 hours (2 days) because resetting causes it to erase all apps, programs, backgrounds, files, ect.
Remove the battery....wait a minute and put it back in.
That happened to me once, I took the batterie out and then back in.
Power cycle take the battery put hold the power button for like 10 seconds then put the battery back in a restart it.
