I got my Razr about a month and a half ago and when i first got it, the 4G was super fast. Now it is slow, when I have it. I haven't installed a bunch of apps on the phone. I live and work in a very populous city where there is 4G. I work less than a mile away from the Verizon store I purchased the phone at. When I am at work, I have a horrible 4G connection. My 3G comes in just fine. It just seems that the longer I have had it the worse the 4G reception is. Has anyone else had this problem or are currently having this problem with 4G on the Razr?
