I'm hoping it will come with the 5.1.1 update, guess we have to be a bit more patient :crying: ; I can't wait to change even more from the stock touchwiz look:crying:
I honestly don't think it will unless enough people complain and request it from Samsung.
I really believe that if not enough people do complain/request it, the SG6 Theme Engine will only be applied to the Note 5.
As Samsung either:
1. Will not know that Note 4 users want it.
2. Will not know that Note 4 users are interested in it.
3. They do know but not enough pressure is being applied on them to actually implement it on the Note 4.
So.....it will just be another selling point for the Note 5 for new buyers (as it is for the SG6), as $crew you, you already own the Note 4, why should we bother giving you that.
Until enough hell is raised over at Samsung from Note 4 owners, I don't think Note 4 users will get this.
Again, I'd suggest copy/paste and modify the email template I wrote above in this thread to ask them for it.
