@mv i just have the same issue, my phone (volla phone) seems to be remote controlled (i had dekko2 and navigator openned, and it tries to open terminal typing a password ...). I shut down it and reboot and it seems ok now. I'm on the stable channel, never change.
I also faced this last weeks some freeze with the touch screen that need to reboot the phone, and the bluetooth with the car (toyota touch and go 2) doesn't work anymore (i have to shut down the bluetooth of the car to avoid connection, otherwise when i'm not in the car i lost sound and micro when calling ....)
