Twitter cards not working when twitted from mobile



Hello everyone…
I’m doing a little web app in which tou can take a pic and then share it with facebook and twitter.
I`ve been using twitter cards to reach this.
When I take the photo and tweet from my computer, or an iPhone, the tweet card does work and everything is ok.
The problem is when I use SOME android devices, some of them work fine but other, just tweet the link, not the photo.

Can anybody help me? <-- this works <–this does not work.

Thank you
