I purchased micromax a90 a few days back and I am pretty disappointed with this phone. This mobile phone has wonderful specs on paper but reality is different. The display is amoled 480*800 pixels but the screen quality is not up to the mark. If you zoom in on web pages you will see images loosing crispness. Also internet browsing is a disaster bcoz while using pinch to zoom in & out feature the links on the webpages are loaded wrongly.
To see the flaw in this mobile visit https://youtube.com/watch?nomobile=1&v=wILUg7lJD9o and watch closely from 7.20 to 8.05. You will see that pinch to zoom opens links on the webpage incorrectly. The camera an 8 megapixel with led flash is a big letdown. The pictures from this camera loose pixels on zooming. There is a lot of noise in the images. The quality of camera is just better than 8 mp Chinese counterparts. This phone is only for making calls , watching videos and using social networking and that you can do for 6000rs on micromax ninja4 . I would not recommend investing more than 6000 rs in brand micromax.
