Since that's not a flagship phone. it's over 18 months old and it was never slated to be updated, you probably won't see any newer versions for it. The Canvas Doodle 3 is the only Micromax for which there's even a Lineage Nougat (7) ROM.

Welcome to Android Central! Official system updates depend on the manufacturer and/or the carrier (if the phone was sold directly by the carrier). Lower end phones typically don't get updated much, if at all.
