Samsung is reportedly developing a sub 5-inch screen phone with an Infinity Display that curves around the edges of the phone like the Galaxy S8 and Galaxy S8 Plus.

Ice Universe - a known leaker of Samsung mobile products who provided details on the Note 8 before it launched - shared a post on Chinese social networking site Weibo that claims the company is working on the phone, but Samsung isn't yet certain if it'll release the phone or not.
