After a week. I would say it's very tough to say anything against this phone. I extremely like its performance. Google worked a lot to compete with iPhone 5. As an earlier iOS user. I was worried about the software optimization of android phones. But it performs all the general tasks like a charm and its very difficult to find any kind of lag. Multi tasking in this phone is pleasure thanks to 2GB of RAM. The display of the phone is as good as apple retina screen. It's made of the best quality IPS LCD panel. Contrast and brightness is excellent. Black levels are great like SLCD-2 of One X. Pixel density of 318PPI is razor sharp. In terms of camera it performs fantastic. Colours are accurate and image processing is really sharp. In day light images, it works like a boss. In low light I took pictures in HDR mode that magically turns a dark image taken at low light into better luminescence. But it takes few seconds to process which is kinda annoying. The front facing camera is also so so in performance in the room. Gaming performance is ultimate in this device. I played NFS MW and GTA VC and it run smoothly without any lag or hiccups. But after sometime of playing it gets warm. The build quality of the phone makes it feel rich, thanks to its glass body. Since I read many reviews telling that phone is too delicate, I was worried about it. But after using I would say it's not that much serious. All you have to do is put it in a cover case. I accidently dropped once on the glass table, nothing happened. The phone is thicker and heavier than Galaxy S3 but not so much. Battery performance is quite average. It works approx 6-7 hours in wifi using. For a normal working day usage it gets enough for a day use. For mobile gamers out there this phone may make you suffer because only about 13GB memory is for user and these new games like NFS MW occupies 2GB of storage.
