In a slightly odd turn of phrase in the blog post announcing the new feature, Facebook says the uploading of 360 photos will only work on iOS and Samsung Galaxy phones. We haven't been able to test this, as the feature is still in the early stages of its rollout, but it seems possible that Facebook messed up and it's actually available on all Android phones (if you can confirm to us uploading photospheres is working on your non-Samsung phone, that would be helpful). We'll see in the next few days as it makes its way across the world

Uploading a 360 photo seems easy: take a photo using a 360° camera app, then upload it like you would any other photo. The photo can then be viewed by tilting your phone around to view every facet of the image. If you own a phone that is compatible with the Gear VR headset, a button in the top left will allow you to 'View in VR.' Insert the phone into your always on-hand Gear VR and you will see the 360 photo in full virtual reality.

Videos in comments

Another new Facebook thing is videos in comments. That's pretty much it: videos can now be posted in comments, using the same bottom left button as for photos. Tap this and it will take you to the screen to select a photo or video. In the top right, there are icons for taking photos or videos. Take a video and it will be automatically inserted into the comments. This adds videos to the growing list of things that can be added to Facebook comments, including emoji, stickers, and GIFs. It's the same on the web, too - instead of the 'Attach a photo' dialog, you'll now see 'Attach a photo or video.'

Videos in comments should be available now worldwide. It's the same for viewing 360 photos, but uploading them is rolling out over the next few days.
