Since the update to version 1.9.2 ME, Locus got this behaviour:
Open Locus again, then hit the back button. Confirm that you want to quit Locus. The GPS icon disappears. Screen off, screen on and the GPS stays disabled.
- start Locus
- Enable GPS
- Hit home button, so Locus goes to background without quitting it
- After a small amount of time, you'll see the system GPS notification icon disappearing and GPS being disabled (good! Locus isn't active and I have the setting "Disable GPS" enabled)
- Hit the power button (screen off)
- Hit the power button again (screen on)
Open Locus again, then hit the back button. Confirm that you want to quit Locus. The GPS icon disappears. Screen off, screen on and the GPS stays disabled.
