touch screen unresponsive to touch
i got my friend's iphone 6, which had its screen broken and the frame kind of bend. and its home button was missing. for a long time it was in the drawer, because of error 53. Today, when i finally put ios 921, it restored completely.
After i put everything back, screen seems to work fine, for a while, then suddenly the touch is gone. I rebooted the phone, adjust the lcd connector, sometime the touch will come back, some time it will not. but even if touch comes back, it goes away within a short time.
If i leave it alone for a while, the touch will come back. but will be gone again.
Any help will be great!
