CameraFigure wise, the Canvas HD scores over the Xolo Q800 as it has a better 2 megapixel front camera as compared to the 1 megapixel front camera of the latter. Both have 8 megapixel cameras at the back.
However, Xolo Q800 comes with a BSI CMOS sensor, which is used in many phones including the iPhone 4. Of course, that does not make the Xolo Q800 equal to iPhone 4 in terms of camera capability as there is a difference between the two in terms of sensor size, lens and image processor. But anyway, we hope the back-illuminated CMOS sensor helps the Xolo smartphone to capture images with good detail.
The exact nature of sensors used in Canvas HD is not known as Micromax has not made this information public, but during our review too we found it below our expectations.
