Micromax A1 made its name popular by its operating system , its runs on androidone which is main reason for its popularty and also for its sales, but sometimes some positiveness attract techgeeks like me . if you ask me my experince I will say its not the right phone to buy .sound is good enough but Its battery very poor, now talking about operating system dont be fool there nothing intresting in it after the marshmallow and nougat is launch , its comcletely a junk piece doesnt support 4g , touch not good and again its battery is really headech .and nothing good about its looks if you have ever noticed the circular shape around its camera everyone would say no
