For the first all other apps work in the background e.g. Navigon, es folder player, blitzer.de are working fine all together running in background.
And i changed the power saving settings for kurviger from autimatic to manually running in the background. I even do not do this for navigon.
There must be another event triggwr this.
Btw. I did manually switch ti look screen, u did not wait untul the programm switch off the screen
However in my Huawei p10 the power settings are a little different (also german). But I found those huawei issues on the web.
Tested locally and worked fine now.
Regards and thanks
