All the three Micromax smartphone Micromax Canvas HD, Canvas 4 And Doodle 2 will soon be getting Android 4.3 Jelly Bean update. The pic shows Android 4.3 running on Canvas HD. We expect the Micromax to update Canvas Doodle 2 in October. Canvas 4 and Canvas HD is expected to get update in November / December. Since the leaked pic shows Android 4.3 testing for Canvas HD only. So their is a chance Canvas HD might get update first.
