Unlike stock Android and other custom Android ROMs, MIUI has a different way of handling the default applications on Xiaomi devices like Mi 3, Mi 4, Redmi 1S and Redmi Note. Instead of offering default program settings to open a file or webpage, MIUI forces users to use the pre-installed applications rather than giving the option to choose a specific user-installed app and then showing the Always or Just Once option, as seen in a typical Android phone.
This can be annoying in case you want to open URLs using Chrome browser but they always launch in the default MIUI Browser. Even if you Clear defaults for the stock apps, then still MIUI won’t show the ‘Open with’ option and you’ll be contented with the defaults apps only.
Perhaps, if you looking to switch the default launcher in MIUI to Nova launcher, etc. or set Chrome as the default browser in MIUI, then that can be easily done. To change the default app settings in MIUI, go to Settings > Apps (Installed apps in MIUI v6). Select the ‘Default app settings’ option and switch the desired apps as default.
A dialog box will open asking to confirm, simply select Replace. You can change default app settings for Launcher, Dialer, Messaging, Browser, Camera, Gallery, Music and Email. The next time you open a file or a link, it will directly open up in the selected default app.
