So ever since the Android 15 stable release USB OTG doesn’t seem to work. Nothing happens upon plugging in the OTG. The same thing works on my laptop and my secondary device. Yes, extend compatibility is turned on from the settings. The same device worked fine back on Android 14.
I’m hoping some dev could look into it on their test devices.
USB is formatted as exFAT. I’m pretty sure kernel has exFAT drivers. NTFS doesn’t work either.
