Using an USB OTG cable, I have connected my Samsung S21 with USB-to-Host port of my keyboard. The display shows me that a new USB connection has been established. I could event start my Music App which has been capable to establish a connection (Midi protocol). All this I have done within one minute but then my S21 crashes (black screen), so even no shutdown.
I have tested this another S21 (failed) and iPhone (success).
I have
- changed the USB cable
- activated developer mode
- tried different keyboards
At least it has been possible to connect a USB memory stick 🙂
It seems that this is an S21 design issue
Any help, thanks in advance
