All of a sudden, my phone just decided not to turn on. The lights on the back that are usually glowing are not. It seems as if the power button isn't working, but I plugged it into the charger and it doesn't seem to sense that either. It is unresponsive to everything I do, and I am afraid to take the battery out or try anything else because I do not want to lose all of my contacts and photos. So basically I am wondering if I take the battery out, will it reset the phone?
