Until now, everything I tried failed. I deleted all Huawei Apps I could find, and stopped all those other Huawei Apps that one can not delete. Did not change anything!
The best I got was 2:55 hrs with Orux when driving in my car. But the next day using Strava I only got 15 minutes. Same with Googlemaps, stopped talking to me after about 1 hr with the screen off (with screen on all Apps work fine for hours!!).
You never know before, when the tracking will stop. It may be 15 minutes or 3 hrs. Never longer!
There is no solution but to buy another non-Huawei phone!
