The
Android smart phone daemon how thoroughly Close. I just bought the only HTC G14 bought me two days to flow all run out, I did not how the Internet, and later learned that this thing daemon. Later I learned off background programs use the software, but turned off, not how much time will start, the best there is really no way to only direct gateway. But this is inconvenient, did not know how to completely turn off background programs?
