Same problem here as others are reporting. Galaxy S20FE, since the latest update, when plugged into the charger it initially pops up with 'Fast Charging' then the fast charging function disappears after a few seconds.
I have also had the phone randomly beeping whilst charging the phone, as though the charging is being repeatedly turned on and off.
I tried to use USB C headphones today (I have 2 sets which always worked). No such luck any more.... I get weird ticking noises through the headset and the phone repeatedly tells me that a USB device is connected and then disconnected.
I have also had a few spurious 'moisture in the USB port' alerts in the last week.
I have turned the phone off and meticulously cleaned the USB port with contact cleaner. It has made no difference. Very annoying.
C'mon Samsung. Going by other reports of the same issues you have messed up your latest software update. Please release a patch for us to fix these issues ASAP!
All of a sudden my z fold says slow charge then won't charge at all. I tried all the chargers I've been using. I did a soft reset and it worked until I unplugged it and then wouldn't work again. I found that it does work with one certain brand new charger I bought on vacation last week. I don't think its the port. I did update while on vacation. Please send fix.
So, I found an update available on my S20FE today (22nd August). I have downloaded and installed it.
And...... The USB port appears to be working properly again. USB headphones work as they should!
Hey samsung there is still a firmware issue with the kernel and packages. I viewed the logs and there is a package that locks out the charging port. When it goes through the process to check wattage and remove the block it fails to mount to the correct path thus NOT removing the block.
Here a month later and I'm also having this issue with both my Zfold 4 and now my Tab S8 Ultra. Pulled out every charger I own and sometimes I can get it to work on one but not the others, then if I switch it around to another or power off and on, sometimes it will work. A Charger that works totally fine in the phone will for no apparent reason not get recognized on the tablet.
I never got a water warning, the charger just never registers at all. Please fix this, my devices are paperweights or painful and there's no in between.
