Hey guys , so i got a brand new S3 In december 2013 , i dropped it an it broke :'( ( both touch and LCD ) I got them replaced by a authorized service . It worked fine 2 months , Two days ago some problem appeared, Touch screen stopped working propperly , it worked only for short periods of time. Now if i press really hard on the right hand corner (Above the return arrow) it works Perfectly ( as long as i keep my finger there) but sometimes it works fine after reboot but in the end it stops (No signs of cracks or damage) , i had CM11.
What i've done until now :
-Deleted CM11 and added 4.1.2
-Took it appart and checked the ribbon ( fine)
-Hard reset
- Dummy file generator
P.s : Everything works on it buttons , volume rockers ..
P.p.s for more info ask me , thak you very much :-\
P.p.p.s Before the freezing screen flashes a bit .

Welcome to Android Central
This is a hardware issue. If you dropped it and it stopped working properly, you're going to have to get it replaced again :-\

If the problem just "appeared" (you didn't drop it again, or something), it should be under warranty for 90 days, so try bringing it back. (Check your paperwork first, though - some shops only warranty parts for 30 days. Some only warranty for 30 days - parts, labor, everything.)
