EMUI 9+ devices

Huawei is extremely inventive in breaking apps on their devices. In addition to all the non-standard power management measures described below, they introduced a new task killer app build right into EMUI 9 on Android Pie.

It is called PowerGenie and it kills all apps that are not on its whitelist. You cannot add custom apps on their pre-defined whitelist. This means there is no other way to fix proper app functionality on Huawei than uninstalling or disabling PowerGenie.

Unfortunately this is a system app and can only be fully uninstalled using ADB (Android Debug Bridge)
