Samsung Galaxy S6 and Galaxy S Edge expected to support the Gear VR
The interesting part about this is that, unlike the Note 4, which sports a pretty large 5.7-inch display, both the Galaxy S6 and Galaxy S Edge are expected to feature 5.1-inch screens. Thus, Samsung might also release some kind of VR adapter for the two handsets, or it could be readying a smaller variant of the headset. Another possibility: the S6 and S Edge actually have bigger screens. Of course, all this is speculation on our part. In any case, Sam Mobile's sources are usually right, so we definitely expect the Galaxy S6 and S Edge to be compatible with the Gear VR - either the current version, or a new, smaller one.
Samsung will likely announce the Galaxy S6 and Galaxy S Edge (which might feature a curved display on both sides) in early March. We'll probably find out then how the smartphones can interact with the Gear VR.
