Buy and experience the class of this phone. Have bought it and I am using it for around a month. I have thoroughly tested it but could not find any claws in it. It's 2gb of RAM allows you an awesome multitasking experience and of course Miui is the best custom UI that I have atleast used. You can click awesome pictures from its 8Mp rear camera with fast autofocus and awesome video recording. It 2Mp front camera also performs very nicely. Heavy gaming is not a Problem here.
With an amazingly tuned processor and GPU you can play high end games like GTA San Andreas, Nova 3, Asphalt 8 without any lags on high graphic settings. Also it has an awesome loud speaker for good music quality. Only flaw in this phone is its build quality, actually its not bad at all but I don't like plastic build phones, but you can't expect more than this in this price. It also offers nice call quality and network reception. An awesome phone under 7k budget.
