Yesterday Facebook offically supports 360 photos on webpages and apps. However not everyone successfully upload their 360 photos. Here is my finding on how to do the upload, in different platforms.
Testing sources are original JPEG images directly downloaded from Ricoh Theta S to PC or phones. So no meta-data on the image files are changed. I think Facebook did some checking on the meta-data of the images so make sure that you’ve kept all of these unchanged if you want to do some editing in photoshop.

Method I – Using the upload button
Click the Photo/Video button on the status box, then select the photo and do the upload
You can see the thumbnail image is still in distorted format
After uploaded, it only show as a common distorted photo
