I have sc600t for android 10,
- echo mem > /sys/power/state on debug uart and removed usb and other connection and enabled airoplan mode.
echo mem > /sys/power/state whenever we are sending device in suspend state.
device is automatically wake up.
even we find all wakeup source from /sys file using find ./ -name wakeup. and disabled it. still device is auto wakeuping.
