Because of huge problems incurred by Note 7, Samsung is speeding up work with upcoming new flagship phone Samsung Galaxy S8. Naturally this time should not be any mistakes, but according to available information including this picture Galaxy S8 is very similar and feels like Samsung Note 8 because of screen dimensions.
Also you can see that there is no home button, so it is very possible to have bigger display. Therefore Bloomberg also conducted an exclusive news that Samsung will be determined using the borderless full-screen design in the next year in March.
If all this is true then maybe we can expect 5.7 inches and 6.2 inches versions. But how time is closer to the presentation of Galaxy S8, so we will have more rumors.
