Add Three Finger screenshot feature

[sambit02]

Dear Samsung team,

Please add "three finger screenshot" feature to all devices running #Oneui 🙏🏼. It adds more to productivity & saves time which palm swipe to capture can't. 

Can this feature be enabled via an ota update? Please samsung add it🙂.

Yes, this is the basic Android feature, doesn't make sense to not have it in an Android phone.
