I have one suggestion.
Replace the S pen from downside of phone to upper side. And implement camera on S pen and these camera on S pen will act as selfie camera.
To take selfie pic the S pen wil come up little exlosing camera lens and take pics. The S pen will be hold tightly by some type of mechanism. And to take S pen out of phone we can use same function mechanism as used in previous models.
As S pens are water resistant so this new s pen with camera lens wil also be same. As last year pen has bluetooth switch same way camera wil have Bluetooth connections so that even pics can be taken with S pen. And regarding cover of phone there is hole for S pen so there will be no problem for S pen regarding S pen poping up. I hope this is usefull.
