It seems that one a moth I forget to charge my battery. A way the the device saves power is to turn off the microphone. I use my microphone a lot and am frustrated because in the last 6 months I've had to do 4 factory resets to get it back on. PLEASE PLEASE PLEASE add a control so that if it happens again I don't have to go through the hassle of having to redownload all the apps that I use and lose any game data too.
Sorry, but you have the wrong forum here. This is the Nook Press forum, for authors who publish to BN.
As a side note, I'm not sure you can turn off the microphone on the tablet. Also, if you plan on not using your nook for any extended period of time, you should completely turn it off, not just put it to sleep.
Hope this helps
