I have a nokia lumia 920 yellow for 6 months. I have owned the 800, the 820 and the 920 now. The 920 made me cracked by its yellow color, which changes the color black as found on almost all phones. Also the finish of the 920 remain for me excellent and very well done. It has excellent capabilities, very responsive, with a screen that can be used with gloves. the definition of the screen is very good, with very deep blacks. The windows phone 8 interface lends itself very Nokia Lumia (and I think this is the best phone I've bones tested to date). The photo sensor (carl Zeiss anyway!) Makes good photo. Internet browsing is good and fluid, the size of its screen to make internet surfing comfortably. One trick me down is that when using the phone on the internet, overheating and sometimes it is so hot that it is impossible to hold the machine in hand, plus it restarts itself when it heating too, which for me is still unacceptable for a smartphone of this quality (concerns was not detected on my lumia 820)
My opinion is mixed about autonomy, which is excellent from the start (which is normal with all the battery) However, after two months of use, it appears that the battery has a very bad self, and also that the overheating phone without you go on the internet, and only by sending sms! the only thing I did to solve this trouble is to reset the phone (I'm twice) and it has solved the problems for 2 months, it begins again. the glossy shell is too brittle and causes multiple scratches, so I would suggest purchasing a protective case, and the screen I do not talk about you, but that's the big worry of all smartphones aujourd 'hui.
To conclude otherwise, I really recommend this phone, very colorful, with excellent fluid and responsive interface, applications owner as heredrive (gps nokia very good usable quality without internet network), a well-built mobile, but with its flaws, and and anyway all smartphones have their advantages and incovénients! But you can buy eyes closed.
