I think it still takes all its design queues from the iPhone, specifically the two ear old iPhone for the sides and front. At the back they've added the same hideous cover they've used for a while, since at least Galaxy S3.
Look, if you want to see semi-original designs running Android you can look at HTC and Sony. Samsung need not apply.
Also, I want to mention Samsung's new design language which is actually Apple's two year old design language. Samsung doesn't have any design language. Anything creative is the product of an outside company, including their ads. Look, if you want a copy of the iPhone, save yourself some dollars and get something much better from Xaomi.
