I have the Note 10 it'll fast charge wirelessly but not with a cable and it will not transfer data by cable either. I've done two factory resets and I've checked the settings fast charging is on I've tried turning it off and on as well as the wireless charging off and on and it just does not want to work. It was fine up until about a couple months ago I can super fast charge and now I can't even just regular fast charge every time you plug a wired connection in a default straight to just the slow charging.
I've posted about this 3 times and called Samsung twice about it. Only regular charge and Super fast charge works on my S20 Ultra. Same thing with my friend who has Note 20 Ultra. Happened after I updated to May/April firmware
