The app has been updated since my last commit but overall it's the same I worked on. That's why the differences from what I am posting and what is seen in the final app.
My work in here was creating all the UI's like video media controls, carrousels the view photos, image gallery, 360 photo viewer and more. Also added Facebook SDK to share photos taken within the app, also did configured the facebook developer account for this purpose.
I also created a system for multilanguage support. Originally each language was posted as a different app, the system supported language change at runtime so I guess they used that for the current app.
