Okay, just thought that I make a short and quick review of the phone.
IMO, I feel that the build quality is solid, however it does not have that 'comfortable feel' when I compare it with the Nexus 4, like how it fits in your hands. As I bought the white version, I can say the back feels nice, but definitely not a rubber grip, and overall quite a solid phone.
Moving on to the camera, in low light condition the camera tends to have lower shutter speed and slow focus rates, even when compared to the Nexus 4. Until an update has been released, pictures would ONLY look awesome under perfect lighting conditions. Otherwise it is just another camera.
The display on this phone is brilliant, if you compare it to the Nexus 4. When you look closely, it looks just as sharp as an Retina display on the iPhone. Colours are more on to the pale side though.
My phone has the 'loose power button' syndrome, where the power button slightly rattles upon touching. However as my issue is not that serious, I don't think I would be getting a RMA anytime soon
On the overall, if you're looking to upgrade from a Nexus 4, I'd say it is a pretty good upgrade, but I am really looking forward to the camera issue being resolved
I would be updating this as I spend more time with the phone, as these are just my initial impressions of it compared to the Nexus 4
peace
