I have a brand new black M92 for about a week and have been quite happy with it until yesterday. While I was adding and deleting files on my SD Card through the USB cable, M92 kept losing connection to my computer but would reconnect itself, over and over again.

This morning, however, M92 doesn't even connect anymore. I can't see the internal storage nor the SD card showing on my PC. The USB cable does seem to charge the device though...

Did I do something wrong, or there's a problem with the device? Please advice, thanks!

Edit: Shutting down and Restarting M92 seems to solve the problem....hope this won't be an recurring issue...
