Have you tried a different cable? That's usually been the culprit for me when I have connection issues. And an alternative you may consider is to just connect your phone to the car wirelessly. My 2022 A4 does this superbly.
There is no issue to connect via Bluetooth, but I cannot use the Google Maps without the cable, so I need to connect via cable. the strange thing, that it works for some phones and for others it does not work!Have you tried a different cable?

I am not sure, but my phone is on the latest iOS version, in addition it works perfectly on my other car Toyota RAV 4Are all the phones using the same version of iOS (both the phones that cause the flickering and those that don't)?
It is 2022, I cannot use the Google maps wireless, it says I have to connect it to a cable.What year is your A4? I can use Google Maps wirelessly in my 2022. Meanwhile, if some phones work and some phones don't work, it could be a phone problem - which may be as simple as lint buildup in the lightning plug receptacle (a wooden toothpick is my tool of choice for cleaning this, never use metal).
