Gps Activation

Apr 2, 2017
I'm having a strange behavior with gps-based apps. Waze, Here WeGo and google maps. These apps have all permissions, I disabled ram optimization, miui cleaner, but the apps only have gps acess when I reboot. After sometime, if when the screen goes off, these apps can't acess gps anymore, even the gps icon doesn't apper in the status bar...

Any clue dudes?
