I have a curious issue. After BT box power off, the power / display on button (r6 new) does not work anymore. I cannot power off / enable display if I press the button. I can power off the device with soft power off via app only.... power on via button is working fine.... but after restart the device I have the same issue.... the screen will shown only after plugin the usb cable.....a whole factory reset does not fix that problem! Any idea?
In addition no power menu (on / off / restart) shown after press the button key while device is up and running. The reset function does not work in this case.....???
After fact. reset FW update done -> without access...

...in addition, double tap to wake up the display is working....curious....
... it seems the power button lost the android software power function...it seems anyone change it...without root....any idea to fix that issue?
