GPS battery drain issue and resolution!!!!
This may have been posted already but I figured out how to stop my GPS from toggling itself on. If I turned off my GPS it would turn itself on and say searching for GPS, or turn itself on when I would be on a call or be in an area with no signal. Even after rooting, installing twrp and flashing Clean Rom 1.1 (THANKS SCOTT) it was still there. Looks like it was the carrier IQ causing the issue. I've done these three steps and haven't seen it since. Step 1: Settings>Location access> check 'Wi-Fi & Mobile network location' then uncheck 'GPS Satellite'. Step 2: On your device go to Settings>apps>runnings>Android System> IQServices> Stop. Step 3: Download 'Disable Services' app, open the app and go to android system the uncheck IQServices. I read that if you reboot your phone it could come back on and you'd just have to do the same steps to turn it back off. Also I heard that AT&T can turn it back on but at least you know how to shut it off. Let me know if this helps
