A:AnswerNo it will not. Only high end Samsung Phones. From Samsung's website, the only compatible phones are as follows: Galaxy S8, S8+, S7, S7 edge, Note5, S6 edge+, S6, and the S6 edge.
A:AnswerThe question you should ask is 'is it compatible with my phone,' and the simple answer is yes. If your phone is older, it may be a little harder for your device to process, but it should work if you don't mind a little screen tearing, which I'm sure you would. If you have an S7 on up, it should work fine.
A:AnswerI'm sorry but I actually googled this same question last night and on Aug 23 when they announced the Note 8 they also in background news launched a NEW "Note 8" Edition to accommodate it.... I know I'm upset too as I have the 2016 ver of the Gear VR (that I got with my Note 7....but we all know what happened with that) and finding out that I need to buy a new Gear VR just b/c the Note 8 is 1/10th of a inch bigger is wrong... I have to though b/c I spent so much on games and apps that I will need the newer one.... here is a link to one of the many news reports I read....
