It's definitely the PHONE in this case. With my EVO Shift, I was able to ALWAYS be connected to Sprint, and even when they were working on towers in my area, I never once dropped any signal. Only time I dropped a call on my shift was when I was in a basement or a random dead zone. Where I work, I was able to get full bars with 3G and it was fast enough to watch YouTube videos in HD with very little buffering. With this 4G LTE bull , my 3G symbol disappears often AND it's slow as . I've went to the store multiple times and have called sprint headquarters multiple times. It is indeed the phone and not the network (at least for some people, me included). Absolutely disappointed that HTC would up something as simple as the damn antennae for their phones. Now I have to buy a whole new phone out of pocket because HTC ed up.
