Finally contacted Sprint about my heat issue with the phone. Mind you I got it on the 21st of June and it has been working fine. All of a sudden they switched on the 4g/LTE in my area and my phone goes beserk. It won't hold a signal, the 3g/4g icon keeps switching back and forth, and it is too hot to touch. It's constantly looking for a signal but can't find one. I was told to just leave it on the regular CDMA mode, but it is still doing weird things. To make a long story short. They are sending out a new device today. Just curious to know if anyone one else has a heat issue or signal issue after the turning on of 4g/LTE?
