We've heard plenty of rumors regarding Samsung's next flagship smartphones, including the ones which claim that the Galaxy S8 would feature an optical fingerprint sensor and a touch-based power button. Now, a new rumor states that the Galaxy S8 could come in two screen sizes: 5.7 inches and 6.2 inches. This is an increase of more than half an inch when compared to the screens on the Galaxy S7 and the Galaxy S7 edge. However, it is being rumored that the screens on the upcoming smartphones curve on all the sides, so there will be minimal impact on the physical size of these devices.
It is also being rumored that the Galaxy S8 could come with stereo speakers, especially since the iPhone 7 already have them. However, it is not yet known whether they will be made by HARMAN, which Samsung recently acquired, but they could be licensed by HARMAN. This rumor doesn't gel well with a previous report which stated that HARMAN-powered speakers could be introduced in Galaxy smartphones, but no sooner than 2018.
Take these rumors with an appropriate grain of salt as we can't be sure of anything till Samsung announces these features on the stage during the unveiling of the Galaxy S8 smartphones next year.
