Need some basic camera features in m51

Can your please add some basic features to samsung m51. The phone has great battery for videos.. However it needs some basic features like..

1. A good video editor that doesnt just crop videos but also allows editing sound and adding effects.. 

Currently we need to use third party like inshot and all.

2. A option to record dual video. This was so great feature to simultaneously record using front and back camera in many of samsung phones. However its been removed in m51.. Its best for blogging or using as car dashcam.

Please enable this feature in future updates..

3. A option to record video wthout audio. This feature is badly needed.. One should be able to record videos without audio. This also removes hassle of editing for many in specofic purposes. and also keeps file sizes low.

Hope these features are enabled in future updates..
