The Samsung Galaxy S8 smartphone hasn't even been announced yet, but the Samsung Gear 360 Manager app already has code for it, possibly hinting at new features for a Samsung Gear 360 (reviewed here) that is connected to an S8.
Bin4ry, the software developer who made the modified Gear 360 Manager app for non-compatible phones, examined the code for the Samsung Gear 360 Manager app and found that it has already been designed to detect whether it's connected to a Samsung Galaxy S8.
The app gives no hints as to what those new features are. We do know that the S8 will have a more powerful processor, and it's possible that new features could be added or unlocked to take advantage of that processor, especially because the Gear 360 does not stitch photos or videos, making it heavily reliant on the smartphone for processing. By having a better processor available for stitching, the Gear 360 could gain new features. For example, the S7's more powerful processor allows 4k video stitching, whereas the S6 is limited only to 2k video stitching. With the even more powerful processor of the S8, who knows -- it may even be possible to add livestreaming capability.
It seems that we'll have to wait and see what, if any, new features the S8 might enable for the Gear 360. What new features you would want? Post in the comments!
