The only thing that people are not liking is the qHD screen. While I personally don't mind it, people coming from high end screens on the Rezound and Nexus HATE it. Apparently it ghosts like there's no tomorrow. I see it, but again, I'm not a HUGE screen buff, so I don't mind it.
That and for some, the non-removable battery is a turn-off. Although, for a 4G LTE phone, this baby has some really exceptional battery life. Add Smart Actions or Juice Defender, and you'll have no problem getting through a day unless you're streaming music or video all day.
Overall I'm VERY happy with this phones build quality, keyboard, call quality, speed. It's definitely a great powerhouse.
Hope this helped!
