Mine and my wife's S6 (2 months old) has developed a terrible sensitivity issue. The phones do not respond unless we continue to tap on a letter or number. I can hit any icon on the phone and it's as if it doesn't recognize it. I have cleared the cache, rebooted, tried Safe Mode and everything short of a factory reset. Very frustrating. I was reading on Android Central and the same issue has been discussed since last April. Has anyone found this issue to be present on their phone? If so, have you been able to get the phone to be more responsive?
