The Photo Sphere option was added to Android 4.2, but it has only been available to Nexus devices. The fact that it’s a stock camera app, it’s unlikely Android OEMs can use it in its current state since they incorporate their own camera software. So far it appears HTC has no plans to implement a similar feature since it would have been mentioned at the One launch event. What about Samsung? Well it appears they might be prepping their own version called Samsung Orb. Supposedly it will give you the same 360-degree panorama photos and according to one engineer, will be even better since it will utilize the S4 camera. For Orbs or Photo Spheres to takeoff, Facebook support would be huge, and word is Samsung is already working with Facebook so users can share their orbs via the social giant.
Just like any other rumor, nothing is confirmed so take it with a grain of salt. However, it doesn’t seem all that crazy that Samsung would implement this in their next version of TouchWiz. If you remember, the Galaxy S III came with a lot of OEM enhancements, and I see that trend continuing.
