I received my 925 (coming from 920) 2 days ago, and I must say, it does feel an upgrade from the 920..
build quality is impressive, phone is perfectly built, I just love how it looks and how it is finished..
The screen on it is indeed impressive, colors pops up much more than on 920 and the black is 100% black.. Only downside is for white, led can't reach 100% white and it viewing angles on white only aren't very good, gladly windows phone 8 is pretty much based on black, and viewing photos on this screen is just nice, colors popping up, very ''alive''..
I hope I won't miss the 32gb from mine 920..
The only thing that's making me crazy on this phone are these crappy post processament algorithms, when you take the photo, they're perfect, nice, sharp.. then when you go view it, green hue, not as sharp, and sometimes colors are way too muted.. Damn, I wish I could turn off this post processament thing.. It takes the camera of 920/925 a level down, although they're still nice even there, lol
Very happy with this phone, just wish it had 32gb and GOOD camera algorithms for post processament.. not going to exchange it soon, even because every cellphone on my country (brazil) is expensive, 925 costs around 800$ dollars and 520 250$..
