I recently found my Note 10+ has stopped recognising the bundled AKG USB C headphones.
A USB device is detected and the phone seems to be attempting to charge it.
I have tried switching the "USB controlled by" setting to "This phone" but it immediately switches back to "connected device".
I have tried booting into safe mode and wiping the cache to no avail.
Any advice appreciated.
Have you updated your device recently?
There was an update to the USB Audio driver a few days ago after which the headphones worked fine.
A system update landed yesterday, I think that may be the cause of the problem.
Does this occur with the device in safe mode?
The system cache partition stores temporary system data. It's supposed to allow the system to access apps more quickly and efficiently, but sometimes things get cluttered and outdated, so a periodic cache clearing can help make the system run more smoothly.
Follow these steps:
- Turn off the device.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the Android logo displays, release all three keys.
- An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
- Press the Volume down key several times to highlight wipe cache partition.
- Press Power key to select.
- Press the Volume down key to highlight yes, them and press the Power key to select.
- When the wipe cache partition is complete, Reboot system now is highlighted.
- Press the Power key to restart the device.
Your phone will take a little time booting up after the cache partition is wiped off of its contents as it will rebuild or recreate those caches. Don’t be alarmed if the phone gets stuck on the logo for a minute or two after this just don’t turn it off so that what was deleted will be replaced successfully. So, wait for your phone to become active. Don’t worry, this procedure is very easy and safe to do. You won’t damage your phone just by wiping the cache partition.
I've tried this again (having tried this before posting). Both times there was no delay either whilst installing system update (the message appears and disappears too quickly to read), or as the cache is wiped (near instantaneous).
The phone reboots even more quickly than it would normally after a powering off.
