Samsung Galaxy S8 sells well, and company isn't resting on its laurels and began already developing the successor of this device, named Galaxy S9. Standard version gained codename Star, and Galaxy S9+ hides behind Star 2 codename.
That's nearly certain that Galaxy S9 will have display made in the same technology as display in S8. It’s worth recalling that Samsung collaborates with Qualcomm company, so we should expect that Samsung will use processor of the Qualcomm's production in Galaxy S9. Other variants of upcoming Samsung's flagship device will be available on the market with equipped Exynos processor instead of Snapdragon 845.
Based on recent reports, Galaxy S9 may appear on market surprisingly fast, because at the end of the year the first copies of this device probably will be ready for selling.
