One of these features is quick access to the camera without unlocking the device. While this is convenient for instant shooting, in some situations gadget owners prefer to restrict access to the lens to exclude accidental launches or unauthorized use.

In this article, we will discuss in detail how to turn off the camera on the lock screen Xiaomi MIUI 12 using the built-in system tools, you will learn what settings are responsible for this feature, how to change the settings of the power button and what additional security measures should be taken to protect your data.

We will look not only at software methods, but also at physical security issues, as well as at frequently asked questions that users have when trying to limit the functionality of a locked smartphone.

Why limit access to a camera on a locked phone?

The camera's quick-start feature was introduced by developers for user convenience, allowing users to capture an important moment in a split second. However, having a button or key combination to access the lens without passing a password creates a potential vulnerability. An attacker who gained physical access to your device could theoretically try to take a picture or even record a video without knowing the unlock pin.

In addition, a so-called “pocket launch” is becoming a frequent occurrence, when a smartphone in a bag or pocket responds to touching fabric by activating the camera and starting recording, which not only consumes battery power, but can also lead to the storage of unnecessary files in the gallery.

Setting up the power button in MIUI 12

The main way to quickly access the camera on Xiaomi smartphones with the shell of MIUI 12 is double-pressing the power button, which is the parameter that you need to change first if you want to protect your gadget from accidentally launching photo or video mode.

After changing this setting, double-pressing the side button will stop activating the camera when the screen is off, which greatly improves security, since physical access to the buttons will no longer activate the lens.

Managing widgets and shortcuts on the lock screen

Besides the power button, there are other ways to access camera features in MIUI 12 that can be active by default, one being shortcuts at the bottom of the lock screen or widgets that are displayed before you enter your password.

Use of the Guest and Second Space mode

To increase privacy, MIUI 12 includes advanced data sharing tools such as Second Space and Guest Mode, and while they don’t physically shut down the camera, they create an isolated environment where access to the main gallery and cloud storage is closed.

If you hand over your phone to someone for a call or a game, activating Guest Mode will prevent you from viewing your personal photos even if the camera is accidentally launched.

How to activate the Second Space:
