I've got Yinlips YDPG-18 about 2 weeks ago and its great. I didn't root it and didn't install any software. I'm using it only as Mame games emulator. Today I was playing till battery got low. I turned the device off and left it charging.
I turned it on after several hours and found that I cannot access internal memory. There is a message on notify bar:
I tried to reset the device, turn it on/off, connect to pc. No luck to access internal memory. I didn't find much info about this android message.
If you have any idea about the problem, please share it.
