Here's a handy series of instructions to help you make Chrome the default browser on your Android:
Android 6.0 Marshmallow
1. With Marshmallow, Google has made it very easy to change the defaults for your most used application like the browser, dialer, messaging or assistant apps - just go to Settings>Apps>Default Apps, and swap to your heart's desire.
Android 5.1 Lollipop and below
Those of us who still don't have Marshmallow on their devices, will have to do a bit of app settings' kung-fu to swap the default browser:
1. Go to Settings>Application>All apps, and scroll until you find your preinstalled default browser (usually called, surprise, surprise... Browser);
2. Tap on the Browser icon and enter the App info screen, scroll down and use the buttons "Clear cache" and "Clear data" to dispose of all the info that may be associated with this browser;
3. Scroll down a bit, and tap on the "Clear defaults" button in the Launch by default section;
4. Now, when you click on a link in a third-party app, it will ask you which browser do you want it opened with by default - choose Google Chrome.
