Instagram has always set a high bar for speed. While other photo apps add feature after feature, Instagram's updates generally come in the form of "Bug fixes and performance improvements." Instagram's latest update for Android, launching on Tuesday, takes the same approach but on a much larger scale. The company halved the size of its Android app, doubled the speed of profile loading, and redesigned its entire experience to both look nicer and perform better — especially on some of the more popular phones in growth countries like Brazil. And that's the goal of Tuesday's update: to juice up global expansion. The first thing you'll notice upon trying the new app is its redesigned camera screen and updated iconography, which better fit in with a comprehensive update the company released for iPhone back in September.
