[Xiaomi / ZTE / others?] Synchronization is never run
Applies to: Xiaomi and ZTE devices (maybe others with "autostart" restrictions, too)
It seems like Huawei, Xiaomi, ZTE and maybe others have added some modifications which are not available in default Android, and which prevent DAVdroid from synchronizing.
To get it working, you have to
- add DAVdroid to "Autostart" (required for automatic sync)
- check DAVdroid permissions (should be requested by DAVdroid automatically)
- disable "battery management" for DAVdroid (required to run sync regularly)
See the screenshots (taken on a Xiaomi device) for more details. The screens make look somehow different on your device.
If DAVdroid doesn't sync after a reboot, please check those things again.
