Chosen Solution
I replaced my screen on my iPhone 6. The keys Y and the ) key don’t seem to work. When I press either of those keys I get the keys beside it. Any suggestions? - Tom
This is either bad screen, or (more likely) a teeny bit of some kind of plastic or something stuck on one of the pins of your digitizer connector–either on the board or the screen. Check for that. If not, then replace the screen to solve. jessa
fault comes from touch digitizer. you may have to replace it display as LCD and touchpad both come together as a module.
I took the Iphone apart disconnected the battery first, then the 4 connectors to the screen. I then reset the 4 connectors to the screen and finally the battery. The keyboard on the screen now works perfectly!
As others mentioned I would try a new screen first, but then also try cleaning out the digitizer connection with some canned air to make sure all the pins have good contact.
Had similar problem with one of the phones. I solved the problem by constantly pushing(massaging) screen. Worked well for me.
Same thing happen to me. It is an original screen and there were a few letters not working. So annoying. Luckyly it was just a missconection of one of the cables. Took them out, blowed in both sides, pluged it back in and it works fine ! Thank you everybody:)
