i recently bought a samsung galaxy note pro 12.2 and it's been working fine for a couple of months, haven't had any problems with it. yesterday i left it to charge and then woke up to use it this morning and the screen wouldn't light up but then i pressed the lock button instead of the home button and it lit up just fine so i left it for like 30 minutes and when i tried unlocking the screen it wouldn't light up again so i pressed the power button for 15 seconds and now it keeps restarting itself. all that shows up is the screen that says samsung galaxy note | pro SM-P901 then the screen with the samsung logo and then restarts all over again doesn't even start the tablet and i can't even turn it off! it's been doing that for at least the past 15 minutes someone please help!!!
