Trying out the new version i noticed one difference in the receiving media protocol. Previously if multiple media were simultaneously downloaded it wasn't an issue but now if f.e. 2images complete download at the same time, only one is actually saved. Clicking on the other image will open the first image too.

Since I don't really communicate using whatsapp i tried to reproduce the above using my other device, a droid, to send images to the N9 and it was pretty reproducable. Both devices were on the same wifi network though I don't think that would have made a difference.

Personally the above doesn't matter but I found it interesting to highlight
