Droid Razr Maxx Signal Loss of Freezing

A

AC Question

My phone keeps saying it has 4G but it really doesn't have a signal really, it freezes, it stop sending text, it stops receiving text, etc. All around, I just want to throw it against the wall and move on.

I am not sure what happened to cause this all of a sudden. I don't know if it is rooted or unlocked or whatever those fancy terms are. A friend of mine tried to do something to it a while back and added apps and did something, but I don't know what. Is there a way to tell?

I have done a factory reset several times and don't know what to do now. I am not to tech savvy on phone stuff these days.

Can someone give me direction...
