I have a nokia lumia 822, and I am accustomed to charging the phone once the battery is dead, as in the phone turns itself off because it ran out of battery, and then I plug it in and charge it. Recently, my phone started to act up and every time I plug it in, it vibrates(as usual when it reboots), but it gets stuck in this loop and continually vibrates without actually turning on. Usually it just vibrates once after plugging it in. I decided to leave it for awhile, but after 30 min it's still doing the same thing. I unplug it and pug it back in and sometimes that does it, sometimes I have to do it a couple of times now. Right now, I tried four-five times and it's not working, and I decided to give it a break and try later. What is going on?
