My htc evo 4G lte signal in 3G sucks, very slow, i notice that with the same signal strenght in 3g the htc one is much faster, could be the hardware of the phone or the location of the antennas i assuming.
I've noticed my 3G signal is far better, but my 4G signal is far worse. This is my HTC One compared to my iPhone 5
This. They must have known Sprint will be on 3G for awhile because the 4G radio is terrible. It does switch between 3G and 4G better but picking up a 4G signal is not among its strengths. Sounds like this LTE phone plays better in the 3G sandbox.
