Xolo Q800
Xolo recently launched its first quad core Android phone called Xolo Q800, priced at Rs 12,499. The Android 4.1 Jelly Bean phone has a 4.5 inch IPS panel display with qHD (540 x 960 pixel) resolution. Though it's not an HD display like the one on Micromax Canvas HD A116, due to its small screen size, Xolo Q800 has a decent 245 ppi pixel density compared to 293 ppi of the Micromax handset. Xolo Q800 comes with a 1.2 GHz quad core Mediatek chipset and 1 GB RAM as Micromax Canvas HD.
The Q800 has a 4 GB ROM. It has an 8 megapixel autofocus camera with backside illumination CMOS sensor for better low light photography at the back, which sounds better than the camera of Micromax Canvas HD. Q800 has a 1.2 megapixel camera in the front. Besides, the Xolo Q800 has 3G (up to 21 Mbps speed, which is again much higher than almost all other phones from Indian brands,) and WiFI, Bluetooth, A-GPS, a proximity sensor, and accelerometer. The Xolo smartphone has a 2100 mAh battery with a claimed 16 hours of talktime, which is definitely great as Micromax Canvas HD provides only 5 hours of talktime. Since Micromax Canvas HD is not readily available this one is a pretty good option and is in no way a compromise deal except if you want a larger display.
