Cannot use Android Auto with new S21 Ultra

[userVy6j27xX6N]

Im having the same issues with my new s21 as a lot of other users. S21 cannot show Android Auto on my car display. It worked before in my car  with usb to usbc and my Huawei (!!) S20. After changing to Samsung S21 Ultra, suddenly it does not work. What a bomber, im soo disappointed. Thought Samsung would be better integrated than Huawei.... and I see currently no solution for this problem. Samsung...PLEASE help us ??

You should have waited for the update to be more stable

Hi. I just bought the phone and connected to the car, and it cannot connect. It has never been connected.

Did you go through the projection setup on your radio and is the S21 listed in the car radio's Projection Manager?

[userVy6j27xX6N]

Yes, on the radio. And the s21 is also connected via bluetooth to the car aswell, but I think that is not the reason why it works OK now for me. It works because I bought a new cable, which apparently did the trick - usbc 3.1 to usba 2.0. My 'old', original Samsung cable (usbc to usba) which worked very well with my Huawei P20, apparently does not work with my S21 ! I don't know why. And Samsung support was of no help to me after 60 minutes in the chat. They kept referring me to Google, even though I stated a lot of times, that I thought it was somehow the cable making the trouble. I also tried similar, samsung cables I already had, and also, they did not work with S21.

Yes, most of the time it is the cable.

Which is strange. Because nothing happened meanwhile to the old Samsung cables - both cables works with my Huawei and my car - like before. But does not work with the new S21 Samsung.  Only difference I know of, is a newer version of Android is running on the Samsung S21, than my older Huawei. And then of course, "old" Huawei new Samsung hardware.

Pretty common nowadays.  I don't know if it's the particular USB chip they use or what but I am also a Motorola guy and when the Razr came out nobody's AA worked.  Moto actually recommended going to like a 6" cable.  Turns out that because of the data transfer you need a quality, certified cable no longer than necessary for your purpose.

Do some cheap cable work?  Sure, but it seems quality cables always work.

If you like convenience and spending money, AAWireless on Indegogo works flawlessly for me and no cable. And when I say flawless that's what I mean, perfect since Sep 21 when I received it.

I have the same problem! It's frustrating.
