Well I have 2 mistakes. No sound and no camera. Camera I can still understand because the difference between 3 and 3+ is the camera module. In the unofficial build of /e/ the problem seems to be solved already as well as in Google’s Android. But that I have no sound either via Aux Bluetooth or directly via speakers surprises me more. Since I found the problem only after the above steps, I thought it helps to mention them, otherwise we are looking in the wrong place.
