Android Auto Constantly Disconnects

[lattemaker]

Hello all! I am having a problem keeping my S21 Ultra connected to my car via wired Android Auto. I can't for the life of me figure out why. At first I was *seemingly* making up that it was happening every time I turned a corner or hit a bump in the road that it would disconnect. Therefore I tried a total of four different USB A to C cables and it still continued to happen. I've tried clearing the cache/memory for Android Auto and it doesn't fix it. I have pretty much narrowed it down to the S21 because it got so bad that for a recent road trip where I needed GPS I switched back to my iPhone 12 Pro Max....I never had one disconnect. So I know its not my cars input plug, and I know its not a cable issue for the S21. It must be the phone itself. I have done everything that I can think of except for a complete erase and restore of the phone. I'd rather not have to do that but I will if anyone things that has a serious chance of it just having a bug or some corrupt file that restoring it would fix.

Any ideas?

Thanks in advance!!!

If it matters the car is a 2020 VW GTI.

It's a known issue with the S21 that Samsung was supposed to fix concurrent with the July security patch. I don't have an Android Auto capable car so I haven't been able to test.

I use android auto in a 2020 kia with no issues.

Curious to know how many more people are experiencing this. It seems like from what your saying its a software issue but it does not effect everyone? It just sucks, I'm still using my iPhone due to this issue...I know that's a first world problem to have but its just as annoying to not be able to use a $1200 phone for such a silly reason.

You have car play and Android auto ?

The Android Auto fix is included in the latest July update for the global, Exynos, models in the AUG4 release, (a later update than the U.S. devices are receiving for July). See this SamMobile article...

Yes. All I have to do is switch out the cable from USB-A to lightning for the iPhone and USB-A to C for the S21.

Thank you for the link. There is one thing that caught my attention though. The article says that some users are experiencing crashing when they go to unlock their phone...Once I plug my phone into the car I just leave it in a little storage cubby and its still disconnecting. I thinkkkk what I might do is just bite the bullet and for a fresh factory reset of the phone and see if that works. I was trying to dodge doing that but at this point I think it may be worth a shot...???

Ok make sure the head unit up to date for AA as apple uses different interface and why you not experiencing issues with it

I had this happen a few times in my car. I have only been back in town for a few days where I have my phone plugged into my car. I haven't had it happen again yet. Like other people have mentioned the July update was suppose to contain a fix for this. It may be worth it to do a factory reset. You can always backup your device via smart switch on a computer. Unless it is a Mac that has Big Sur, Samsung is lazy and won't update smart switch for Big Sur.

Try this cable from Anker 3.0

This happens to me occasionally as well, in a 2021 Subaru outback with a pixel 4a 5g. The audio pauses briefly them returns 5-10 seconds behind where I was. Is not store frequent though.

Is it disconnecting or freezing? I was having an issue with my Note 8 freezing and it seemed to happen over bumps or after around 10 min consistently. I tried all the suggested fixes then noticed that under connected cars my car was there twice. So I deleted the cars, then re added it. Then turned off "add new cars when connected" or whatever it says. Hast frozen since. Yours might be a different issue but if all else fails you can try this.

Its disconnecting. And that may have been the case. I went ahead and did a complete factory restore of my phone but have not had a chance to see if that fixed it yet. If it hasn't then I'm going to be lead to believe its either a problem with my car or phones USB port. If that is the case I will make a claim to Samsung to get a warranty replacement. I don't believe its my car's port because my iPhone which I've used a lot with my car never disconnects and never has any problems with its wired connection.

I had that issue with my Jeep Renengade. Drive a 2020 Charger now. No issue stays connected. Now I have s21 ultra

Mine would frequently disconnect when I uses the cable that came with my phone, even though it was brand new. Switched to a different USB 3 cable and it rarely disconnects now. There have been so many AA issues though, so I'm still afraid to update every time an update comes out!

This, from SamMobile...

Galaxy S21 Android Auto fix pushed back to September

"Samsung has pushed back the update to September, as seen on the official Google support forums. It also states that the fix will arrive as a standalone update, and not bundled with the September security patch. It effectively means that Galaxy S21 users are stuck with a buggy version of Android Auto for nearly a month more.​"

So, there you have it!

I would suggest you buy a new car and try out how it works

Tbh, it happens with me (sometimes) on my Toyota Highlander as well, but i always blame it on faulty cable, so all i would do is plug out and plug it in again. I am still on June security patch so not sure if July patch resolves the issue.
