"Unsupported Device" strikes again

[NJMike]

I have a Galaxy A23 5G. For the past few years since I've had it, I have always had a pretty much perfect experience with using Android Auto in terms of the initial connection.

Recently, however, I have noticed it has been throwing me the Unsupported Device error, which I have to unplug the USB and plug it back in. To my knowledge, this happens with any cable I use. My previous Galaxy A11 had this problem, although pretty much every day.

I have ensured that all my settings were fine, that my apps were up to date, that nothing is set to Optimized in batter saver, etc.

I am still having this issue, does anyone know a fix? It is very annoying.

Hi
Have you checked the charger port is clean from any debris?

I haven't done that in a while like in a few months probably. I will try that.

Yeah definitely, I get lint sometimes from my work pockets and periodically have to clean the ports

I think this may have worked? Haven't had it happen yet. Though I also wonder if itsbecause I am getting rid of the headunit's disclaimer screen before connecting, as I noticed that when I do so, the AA icon appears on the headunit screen almost instantaneously. Before, I would just plug my phone in as soon as I turned on my car and would allow for it to automatically put me into AA. I wonder if it has anything to do with that.

Yes getting rid of the disclaimer will speed up the process

It started happening again today as I got in my car to drive to work.

I don't know how much any of this would help, but here is my set-up. The USB is coming through my glove box, I don't know if this ever has anything to do with connectivity. But it was how the Geek Squad installed it.

I see you have an aftermarket head unit, that USB cable u need to follow behind the unit see if it's fully seated as any pulls can pull it out from behind the Head unit

Yeah that was always something I was afraid if as well, though sadly I do not have the expertise enough to go about disassembling things to get back there and see.

Since I'm in the Auto industry when I install a unit for myself or family and they have these loose USB cables I like to make a port like factory so you never see the cable just plug it in that way looks clean and professional

And I make sure the cables, if not hardwired to the HU, are secured in a way that they do not pull out or disassemble from vibration (tight electrical tape wrap, zip ties, etc)

Yes

I discovered something today: If I leave the phone plugged in instead of unplugging/replugging after the Unsupported Device error, it will eventually reconnect on its own after about a minute; this feels to me like it isn't actually an issue with the USB, but with the app itself.

So would anyone know how to make the AA app more responsive instead of it being a dice roll whether it decides to work right away?

AA has been problematic over the years , trying previous version, beta version or wait untill updates are out has fixed it in some cases
