I recently installed Dingux dualboot loader and at the same time I started to have problems with powering on the device with power button...
Every now and then when I try to start my dingoo by pressing power button nothing happens, my Dingoo stays completely dead. When I connect USB cable and keep it connected until Dingux logo dissappears everything is ok again. If I disconnect the cable before logo dissappears the Dingoo powers off.
The most weird thing is that I think this happens more often when the battery is fully charged. When battery is half empty the dingoo usually starts without problems also from power button.
Ideas anyone? I would not like to deinstall the dualboot as I really like Dingux, but I would like to be sure that the device starts when I'm not next to a computer!
