Facebook for Android users in Canada might be seeing a new search interface show up on their apps. The interface shows you topics it thinks you might be interested in along with links and posts related to them. So, for example, you like music, it'll surface content related to the topic. Think of it as something similar to Instagram's search page where you're shown photos from topics you might be interested in. The test is being conducted here, in South Africa, and in the Philippines. There is no word yet if it will be getting a wider release, or if the testing extends to iOS. But the renders Facebook sent to MobileSyrup show the interface on an iPhone.
