Micromax canvas doodle 3 was a very good phone. Battery backupbis also good 2500mah.
Camera quality is fine. A big display helping in reading news and books etc. Usually 6 inch screen. The main drawback is internal memory is 8 gb usable 4 gb which fill up very fast. App storage very low little disappointing.
But the overall the phone is good. If u wana buy then go for it. But see your pocket first for 6 inch phone its a big deal.
