Thanks a lot bro  it works better and lots of features

Even the oldest ones like J7 prime still has that feature..

Then is there any way for us to enjoy concert hall experience ,any 3rd party apps or anything

Will it ever be available for mid range users like M31

Also, they took away concert hall effect. Some latest phones can still enable it by downloading sound assistant from galaxy store, but for m31 its not even available in store. This is so disappointing. Dolby atmos doesnt do much..
