The interface in MIUI Security is as to be expected from essentially any security/optimization app, and it follows in line with other apps developed at Xiaomi. It packs a wide variety of features, but thankfully, accessing each of the tools is very intuitive. All you have to do is scroll down through the main menu to select any function you need.
MIUI Security keeps every file on your Xiaomi smartphone safe and secure. You'll also find options to clean up anything you don't use or need anymore. Opt to restrict access to certain apps, increase your system speed when running a CPU and RAM intensive game or app, or you could also set it up so it seamlessly provides a fully resource-optimized experience.
MIUI Security has all the essential tools to make your device work like it's brand new. Plus, it'll identify suspicious files (that could potentially pose a threat to your smartphone's security) as well as scan for any clunky files that are taking up too much space.
