Phone Problems

About a year ago, I decided I had been out of the technological loop for long enough. I had a cell phone that I liked, and did a great job, took good pictures and was fine for texting, but it wasn't a "smart phone." Sooo, I went out and got an android smart phone. I loved it for awhile, but I have about had it with this phone. It messes up a lot, just on the normal stuff like phone calls, although it also turns itself off at very inopportune times, and I have to take the back off and take out the battery in order to get it to turn back on. I'm really wondering if I shouldn't just pitch it and go back to my trusty old "simple" phone.
