DJI GO Android v4.3.0 - signed out of app resource use
I signed out of the app to see the resource utilization.
Why is SwUdpService and timer-0..4 + amapLocCoreThre running when signed out of app?
Why is two location listeners active (1m and 900ms) ?
Every 5,0s: adb shell dumpsys cpuinfo | grep -A20 dji.go satellite: Sun Sep 23 08:38:33 2018
