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.

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)
