I have a Revolution by LG that I have had to have replaced after a month of use, the new phone still has some of the same problems as before, the phone will just reset by itself, the 4G turn to 3G when I'm in a 4G area or won't get a signal at all. It is very frustrating to be using the phone and it just resets, whether using the phone, listening to music, audio books, or you go to look something up and you have no signal at all. Does anyone else have these problems?????
