Touch ic problems iPhone 6plus
So i got a iPhone 6 plus today with the grey bar on top indicating that the touch ic was going bad, or not soldered well. i have replaced the cumulus chip and now i have no grey bar, but the touch is a little less responsive near the letter U if you were texting. or trying to slide backlight brighter 3/4 of the way it stops.
Do you think this is a problem with the chip i replaced or is this caused by the mason chip?
