+**(169) Why does the app not start automatically?**
+
+FairEmail requests Android to start the app when the device starts up.

+Some Android versions, such as EMUI, have settings to enable or disable auto starting apps.

+For example for Huawei/EMUI, please [see here](https://dontkillmyapp.com/huawei) for a guide.
