Back in the "day", my Galaxy Note 4 had this feature and it was very cool. You can shoot videos with 2 camera lenses at once. However, this new implementation doesn't work well and needs a UI update.
1) it's not intuitive to use the controls. As it is, both cams face the same way. I need one to face me, but there's no button for that.
2) it needs filters for each aperture separately. Now, you cannot do this.
3) users should be able to zoom each aperture independently.
4) users should be able to move the smaller screen to different positions.
Anyway, I've been asking for this feature to come back, so thanks for it!
