So you think Indian smartphone brand are less than any Chinese smartphone brand?Just think if you are getting issues from such big brands who invest in R&D then think how Micromax phones will be. You answered yourself, this phone ain't any good.
Big brands who invest in R&D do nothing but make a smartphone plan and keep adding and removing some specs and name them with Oppo or VIVO or Realme and Redmi or POCO or Mi. So it's nothing new as these brands.
I personally belive 2 smartphones in a year in every category are enough. So, they are doing that although it get delay because of COVID.
