Why is slow mo not available in low range phones eg m30. It has the processor which can support slow motion. There are other companies like MI which provides slow motion and many other features in their phones which are not available in Samsung.
I have same issues the 3rd party app slow motion is not smooth as default feature in camera so as many of us will tell Samsung using Samsung chat or calling Samsung they may provide it in next update as they have provided it to the A30.
