finally!!

Does anybody know when the s8/s8+ theme (samsung experience) is coming for the s7 series??

guys do you have the feature that unlocks the phone with the fingerprint sensor without turning the screen on?? (you just touch the scanner and it unlocks)

guys do you know how to uninstall the touchwiz home (stock one) and replace it with the touchwiz home of the s8??? i tried installing it but it says that there is an app with the same name..(touchwiz home)

guys when you send questions to samsung via samsung members how long do they take to send you back...because i asked one question and its been 3 weeks and i havent got any answer...
