Hi all... Just trying out my new Air2s and took a sphere shot. Shows up as it should after it's taken it, but once downloaded on my phone the image is flat??.... How come?

You need a viewer to make it 3d,  If you upload this to say Google Street view it would become 3d again. or you can host it on a website with a free tool from http://pannellum.org

One alternative is to use https://kuula.co - they have a free tier for 100 images or month or you can use your free Skypixel account that came with your DJI account.  - http://skypixel.com

If you use Skypixed you can embed them onto the forum for interactive viewing.

Uploading to Skypixel works for me
