Rumor from the supply chain says the Samsung Galaxy S8 will feature 2K screen, no home button
This rumor contradicts earlier reports that called for Sammy to turn to a 2160 x 3840 UHD resolution screen to make VR look great on the phone. As we pointed out before, using a screen with such a high resolution would put a terrific strain on the battery, and could force Samsung to sharply hike the battery capacity on the handset. In light of the Galaxy Note 7 issue, which could have been battery related, it seems wise for the company to stick to a 1440 x 2560 resolution screen if just for one more year.
The supply chain also reports that no component vendors received orders for parts that would be used for a home button. This would seem to indicate that the phone could have an all-glass front with Qualcomm's ultrasonic fingerprint scanner embedded under the front glass. It sounds similar to the all-screen look on what is allegedly Meizu's new phone. Meizu's device allegedly carries a very high (close to 100%?) screen-to-body ratio. It also happens to be a look that Apple is reportedly going to employ for its tenth anniversary Apple iPhone in 2017.
As usual with a rumor like this, we suggest that you take it with a grain of salt.
