I installed the OTA for kit kat and my phone lost touch control as some other threads are stating. I tried everything, odin , side loading and nothing worked so i went to device center with my active that is no longer under warranty. As soon as i told the representative that i have the active and i did kit kat update he said "and your touch screen doesn't work?" He told me they had tons of people come in today for that issue. I always look on xda first when i have a phone problem so i just wanted to write this post to warn people not to do ota because this could happen, and also for people dealing with this it is a known issue and the device center knows about it.. This guy was awesome btw he even swapped out my battery and gave me the new back cover. Its the little things in life:laugh:
