Using a Huawei Mate SE (BND-L34) running EMUI 8.0.0 and android 8.0.0.
I'm using a few applications to record my GPS tracks as I ride a bicycle. OSMAND, GPS Status and Maps.me to name a few.
The problem: when I lock the screen, the GPS radio stops maintaining the 'fix' and apps that track or record my position hang up sometime soon after locking the streen.
I've already done the following, which did improve the situation:
- Apps & notifications
- Settings (bottom icon)
- Special access
- Ignore battery optimisation
- Push "Allowed" and select "All apps"
- Select "[ANY ABOVE APPS]" and mark "Allow"
This makes it so that for a few minutes after locking the screen, I can unlock the phone and find the GPS will show me in the app where I am, and has recorded successfully.
However after a few more minutes, I unlock the phone and the GPS is in a location from many minutes previous and stopped updating the location.
I have ALSO tried using an app like GPS Keeper Lite, although this did not solve the problem.
I have a feeling that the phone is doing something to save energy but I don't know where or how to solve this.
Any help will be greatly appreciated.
