After getting the new update I noticed an issue with my touch screen not responding to a certain area. I was in setting trying to turn my wifi on/off but it would only respond either airplane mode or bluetooth on/off. If i scroll the screen any at all touching the same area works fine. I also noticed it doing the same under my group contacts. Trying to select family it would only select coworkers or friends group. While on my home screen and in most apps it seems to work fine. I've tried a factor reset and also recovery. Any suggestions as to how I could fix this would greatly be appreciated.
