On AAWireless devices which have been bought on or after 1 September 2022 we only provide support for phones on the official list of Google: https://support.google.com/androidauto/answer/6348019?hl=en#zippy=%2Candroid-auto-on-your-car-display-wireless. This means we do not support Huawei phones.
On Huawei phones randomly the screen can become black, with only the bottom bar shows.
We have no solution for this issue unfortunately. It's a phone side issue.
