This morning I woke up to see a system update for my phone and I accepted. This S4 has been a stable rock with no issues since I got it 8 months ago. However the 4.2.2 update I got this morning is causing my phone to get super hot, freeze, and shut off often. When I look at the status bar across the top, the GPS icon is flickering on and off, on and off, on and off and eventually the phone locks up. Not only that but a separate issue was about half of my icon shortcuts are gone. The apps still exist but the icons are gone. The major problem though is the GPS issue. I was able to navigate through and turn off the GPS and now the phone seems fine. However, I use the GPS often so this is not a long term fix. My phone is not rooted and I don't have any backups so I'm not sure if I can rollback to 4.4.1 or this doesn't exist. Does anyone have any information about the GPS as it related to the 4.4.2 update and how to fix this problem? Thanks!
