I have tried the following to connect to my PCs and Android Auto. I am positive its a phone setting, not cables or drivers:
Approx 10 cables inc A-C and C-C new old and specific Data and OEM cables.
I have used Developer/ USB debugging
Diagnostics that confirm USB connection
Samsung USB drivers
Reset the phone
*#0808# MTP + ADB
Un-installed Android-Auto re-installed
All I get on the phone is "Slow Charging" notice
Is there anything I am missing?
I have tried all of that (several times) the notice Transferring files/Android Auto. never appears on the phone, This is what I suspect is missing or the reason I cannot connect to Auto or PC thanks for replying
am having the same issue, not connecting, only showing slow charge. I have not been able to connect in days. Tried two brand new cables.
I still haven't been able to fix direct USB connection however after trying out several wireless connections via a 3rd party suppliers, I can highly recommend AA Wireless https://www.aawireless.io/ it worked within seconds and still have not had any problems.
I suspect the USB connection is a phone problem and driver and will only be fixed in future updates (not good at all Samsung!)
The last time this happened I changed the the USB option from transferring files to USB tethering and it was able to connect. I am going to try that today and see what happens.
It's kind of annoying to be working on one part of my trip then suddenly not working anymore. 😕
