I replaced the screen of a Samsung Tab A 8.0 T290. Touch was working fine. Client said there was an update and updated it. The touch stopped working. I ordered a new screen thinking the one I installed was defective. Same issue, the touch was not working . Client claims he contacted Samsung and Samsung would have said the firmware recognized it was not an original screen and locked the touch. anyone heard about this? Is this something new that Samsung does? I replaced it on another tablet same model and no issues whatsoever. please advise. thanks
I did a rollback of the Firmware and it fixed the issue
I have this same issue on one of my kids’ tablets that has a replaced screen. Rolling back the firmware to the previous version fixed it. Looking over the system logs from before and after the firmware update and seeing which devices are recognized, I suspect they left a driver out of the firmware either on purpose or by mistake. Somehow I doubt Samsung would do this on purpose as I wouldn’t expect replacing screens on one particular model of tablet to be a big source of revenue for them but you never know.
