I had voiced my disgust over the Charge's radio and its RX/TX capability in a former post, now I have just proven it to myself.. I thought maybe it was just my location. IT IS NOT. My two daughters have just purchased a LG Revolution and I am extremely jealous. Their phones actually work in 4LTE mode just fine at my residence. They get between 2-4 bars of LTE at all times. I can barely squeak out 1-2 bars if I'm lucky and near a window with my Charges'. Their data / speedtest work anywhere in the house, my wife's charge and mine have to go near a window to do that and half of the time to make a phone call. The Charge's radios are JUNK. I am not joyous over the LG Revo's interface, but their network communications are vastly superior to the Charges. They can even have their phone clipped to their side and receive calls at my house, which is impossible with our Charges.. We have to set our phone near a window to get it to ring a lot of times.. What a bummer... Never another Samsung POJ.
