The new TouchWiz interface on the note 4 has all of the features of Google L and more...Samsung even uses the same multitasking window screens.....and the white backgrounds etc.....nice to know...the transition to Google L for the note 4 should be easy...only difference Google L is a simpler interface than TouchWiz as usual
This is hardly the only difference. Touchwiz slows down adoption of new updates and also consumes a TON of memory. Maybe in a few areas of looks it might be the same, but that's where it stops. Touchwiz is garbage.
