It’s annoying when a link opens in a certain app rather than in the browser. It could be a YouTube link, a tweet, or a Facebook page — you’ll end up waiting around while your phone shuts down Chrome (or your browser of choice) and fires up something else.
It’s easily fixed.
Go to Settings > Apps and find the app that keeps opening. Once there, scroll down to Open by default, press it, and then select Clear Defaults.
If that doesn’t work, try doing the same with your browser app as well.
