I have just installed an Android screen in my BMW I am finding a couple of issues, when just running the Android app I keep getting the screen go darker and a white bar appears at the top of the screen and it will not go away, I have tried swiping it both ways and up and down and nothing happens.
When I run it in Carplay mode with my iphone XS I find the GPS very weak, I can get my location then travel 1/4 mile and it loses me and takes miles to find my position again.
 The screen does have 4G connection and also it connects to Iphone Hotspot
