.....that there is a loose electrical connection to the backlight display or a a defect in the circuit board for that feature. I suggest you take to a phone repair center. Is the phone still under warranty ??
Hi!
My Samsung Galaxy Ace seems to be working fine except that the backlight doesn't work. It used to come back on with a few hits of the phone, but now has gone all together. If anyone has any ideas as to how I can fix this (myself), I'd really appreciate them.
