Digitiser problems after screen replacement
I replaced a screen assembly on an iphone 5 after the old one was smashed, and the person who I fixed it for just called me up today saying that the touch screen is acting all weird and basically having "ghost touches" on the screen, but its apparently its only happening along the bottom of the screen, so when using the keyboard when the spacebar is pressed it will continue to hold the spacebar down.
What could be causing this screen to appear to be faulty? Does the phone just need a hard reboot (hold home and power button until it reboots) or a restore? or could it actually be a fault in the screen?
