As we are slowly reaching the end of the year, rumours about 2018 models begin to surface online. For now, two companies have been rumoured to be working on flagship smartphones for early 2018 and those are OnePlus and Samsung. OnePlus wants to release its flagship model with bezel-less screen earlier than this year, and Samsung has similar plans.
According to SamMobile, Samsung will have similar flagship lineup for next year, presumably one will be the Galaxy S9 and the other being the Galaxy S9+. This leaked firmware has also revealed model numbers - G960FXXU0AQI5 and G965FXXU0AQI5, which translates to the SM-G960 and the SM-G965. Since firmware development begun earlier than last year, the new models could indeed launch earlier.
