Micromax canvas a1 is a very nice mobile by partnership of Google .
1.The best part of this mobile is it will update its android version next two year for free.
Size of mobile screen is very good 4.5 inch.
Camera quality is ok
4.internal memory is very low first version of this mobile is only 4 gb, and second version of this mobile is 8 gb. Both version are low for internal memory.
But over all this mobile is good.
