After new screen replacement display screen is behaving erratically
I run a small iphone repair service..
I bought a iphone 5 front screen with LCD off ebay for £29.00.
Since the repair the customer has noticed that the display screen is behaving erratically by opening and closing apps by itself, making random calls, ending calls, and typing passwords is the most difficult of all as it decides to make it up .
Is this because the screen is of low quality?
It seems to be ok after i have fitted it then starts behaving weird?
Please can someone help me
Thanks
