After doing a reset all settings to get rid of some bugs I've exoerienced on iOS 8.1.1, I experienced something else. I tried to swipe up to access my camera from the home screen and nothing happened. I tried a few more times and nothing. I tried swiping down for notification center and nothing. It didn't resond on the home screen or within apps. The funny thing is it worked when my phone was locked. I did a reboot and it fixed the issue. Later that day it happened again. I decided not to reboot and just wait and see if it corrected itself. After a few hours it started working again. Anyone else experience this? I'm running 8.1.1.
