Hey if someone from samsung developers is seeing this post than i have a idea for you
For design pick your one devices m51
Now as you know it has side mounted fingerprint sensor than you can give some options for making it more useful than ever
For example you can remove volume up and down button and give an option that double tap that fingerprint sensor and slide it for increase or decrease or decrease volume
On other hand yo uh can also do like double press and than long press for flashlight
