I believe Snapchat has an option to reopen the snap you just viewed, but I don't think it's available for very long - maybe a couple minutes after viewing tops?

No excuse I can think of for the media existing for more than a few minutes post-viewing.

yea this is ridiculous, they have lied through their teeth about what happens on Android. tho of course its probably half clueless negligence or a missed change, half not caring. all the same
