I have a Galaxy S3 and the app is updated to the most recent version available for Android, which is indeed 1.3.3.
However, you may see people talk about features that you don't see for a few reasons that I can think of - first, Disney and whatever third party developer they use seem to constantly push new features to the iOS (iPhone, iPad, etc) version of the app first and then the Android version of the app gets it a few weeks later.
I specifically remember reading about the ability to link a resort reservation in the app, but it was weeks before I saw it because the iPhone people - very annoying.
The second reason may be that if someone has a package from Disney (hotel+tickets) or an AP/PAP they may be seeing extra stuff in the app as part of the (slow) rollout of FastPass+. Every time Disney decides to run a test, they seem to pick people who have hotel+ticket reservations.
For my August trip I rented DVC points and we already have older "no expiration" paper tickets from our last trip. So while I can link the DVC reservation, I still have no way to let Disney know I also have valid park admission - once they activate this part of the NextGen system on the My Disney Experience site and the app, we'll be able to link tickets as well as room-only reservations and that will be the key to being able to reserve FP+ online ahead of time and see it in the app. Until then they are testing it only with people that have hotel+ticket reservations.
