I bought this phone as an upgrade from my G3. I would say that it is better in every aspect. The camera takes amazing pictures, provided you have enough light, as in low light the image gets grainy. The screen has a really good contrast and I use the second screen daily. The DAC sounds amazing, and the phone speaker also puts out loud sound, although there is almost no bass. It also runs very fast and I've only seen the phone slow down once or twice. I completely recommend this phone!
I've attached some pictures I've taken while I've had the phone (almost 6 months!)
