Edit: However - the phone reboots after a few minutes on a wireless charger in a car. I thought it might be android auto but this requires a bit more testing to rule this out. It's not waze at any rate. The phone reboots after some time in a car. It's not the wireless charger, or waze, or android auto, or bluetooth.
It also gave an error camera not working when trying to use a camera in an external app (eg firefox and google translate) but I solved this by installing gcam (google camera)
Firefox keeps crashing and is pretty much unusable. Edit: Brave crashes often as well
Edit: I can't get Google Translate to translate texts
Edit: The camera app often won't open
Any help is much appreciated, as long as I am not near a wireless charger this is a vast improvement on xiaomi.eu for stability!
