Touch screen sometimes facing Ghost touch & Unresponsive right side
Hello..
I have bought an Iphone 6 Plus (USED), but the thing is, after 3 days, I found that the Touch screen sometime act weirdly, 30% of the right side of the screen doesn't work, Ghost touches and the touchscreen become unresponsive in some places in the right side of the screen,also a multi-touch may occur however the left side is working perfectly,
Also when i tried to shake my Iphone I heard something like the battery is out of it' house or something, I guess the previous owner had a low quality repairing service that cause this, I mean could this happen as a result of a bad connections between the LCD and Board ? should I try to reconnect the Display?
Could it be a Touch IC Fault ? or just display issue ?
Thanks very much.
Is this a good question?
