Why does screen flicker bad like jitter studder shake virus for tabletVideo here https://youtu.be/yVZgJov8G1c
Answer to "My tablet wont boot or charge"The problem could be you battery or io port if you don't feel vibration. Its possible that the screen might not work too.
Answer to "Why isn't the touch screen responding?"Did you drop it. the digitizer top glass might be cracked and broken or the cable could have been damaged or unplugged. I have a crack screen and touch still works. There's an app called phone tester but u need to be able to touch. Unless there's USB mouse support?
