Update Windows 10 Mobile Build 10136 brings native GIF support & a cool gallery tip
It seems ability to play GIF files natively comes with Windows 10 Mobile Build 10136. Not sure whether it was possible with earlier Windows 10 Mobile builds but it seems Windows Phone 8.1 was not able to handle GIF images natively. Not only GIFs appear in the “Photos” app now, but animations also play when you open the GIF image by tapping on them. You can also share the GIFs via mail and messaging and also play GIFs received via mail and messaging.
