[Q] Screen flickering problem topic

Hello guys I'm pretty new with samsung
I have a GT-N8010 and there's significant screen flickering problem!!
I searched for some info
Afterwards, i tried to force stop and uninstall some 5h1t app from the device but the problem is still here

The problem was quite minor in the first few month, it raerly happen and could be recover immediately by turning off and on the screen again. But it was not tolerable these days as it wont recover by that and keep getting more and more serious like crazy colour changing and i cant easilly find a way to stop it :'(

What should I do to fix it??
I dont care if I have to root it or something, just hope i dont have to format the as i use the S-Note for copying lecture notes and i dont want to lose them (maybe i should backup with Kies to prevent that)

Yes, the main function of this 10.1 is to copy notes and it cant even serve well here, hope if someone could help me

(I have some experience on flashing different roms and mods on Sony devices, so maybe i can handle some on samsung as well)

[Q] Help! Screen flickering and blue stripe down side topic

Well my 3 year old was using my xoom tablet as his Nextbook tablet is being sent out to be repaired(so this is the second one he has broken!). I believe he has dropped it and now we are getting a screen that is flickering and is showing a blue stripe down the left side. The screen pulls up and I am able to swipe around but its very touchie. Not responsive at times. I did a hard reboot(vol up + power) and no luck. I also reset the whole tablet. I've also plugged in the tablet to the tv via hdmi and it works fine using a bluetooth key board. So my question is will replacing the screen make this tablet fully functional again. I don't believe the software has any issues. Thoughts?
thanks for any help!!!!
