I have had this phone for about three months, It works great, never had issues with it being slow, big screen, awesome. But recently it has been prone to just switching off at random. This is the third time it has done this. It only happens when the phone is asleep, then Ill press the home button, and nothing happens, Ill hold the reset button combination, still nothing. If I remove the battery and then replace it, the phone will vibrate once, then do nothing. If I replace the battery and then plug it in, it will vibrate once, then do nothing. The last two times I got it to work was by leaving the battery, microSD card, and SIMcard out for about 12 hours and then putting them back and plugging the phone in. Then the battery symbol shows up and the phone will boot. this is happening more frequently too. Any suggestions? Thanks in advanced.
