While I'm sorry you also have the same issue
@Scott191 I'm glad i'm not the only one as a random intermittent fault will be so hard to get the dealer to do anything about!
Ah interesting I hadn't realised the USB-C port also works for AA / ACP, thought it was purely for charging. Will find a suitable cable to give that a go and see if it improves things.
I am unable to tell specifically if the front vs back speakers cut out unfortunately as i'm unable to tell which directions sounds come from very well as I'm 100% deaf in one ear 😅.
There was one occasion where the bass from Android was very "tinny" and completely fine on iPhone, but that seems to be the Android phone's problem as a reboot of the phone resolved that.
I also had an issue where the GPS positioning of the car on AA was off on the next street (i.e the car was drawn parallel to the road i was actually driving on) but voice commands were still 100% accurate to the journey I was making. I assume that was an issue with the car's internet connectivity as the GPS time was also off by 1 hour at the time. Issue seemed to go away after I left a specific area.
