Some devices (especially Huawei, Xiaomi, Samsung, OnePlus) have a very aggressive energy-saving mode. Due to this, background processes are quickly terminated. Therefore, it is necessary to disable the energy-saving mode for this app. Please note that further settings may also be necessary depending on the device.
