Take out the battery, then take out the Micro-Card. Then put back in and restart. Hopefully that will work. Once I did have to do a reset to Factory, and reinstall everything. I have had the phone for 8 months, I think. And this happened 2x. It doesn't really like, fast and confused access to apps. Also, it really doesn't do well traveling with the WI-FI on. The combination of searching for a Wi-fi to connect with, and the phone trying to keep signal, doesn't work. So make sure if you are traveling turn off the wi-fi, because it will lock up like you are experiencing.
