The lock screen on Xiaomi smartphones is not just a barrier between you and the system, but a real multifunctional control center. Many users do not even realize that the standard unlock slider hides dozens of useful features, from quick access to the camera to control a smart home, while the MIUI interface offers such a deep customization of the lock screen that two smartphones of the same model can look completely different.
In this article, we will take a closer look at what the lock screen is on Xiaomi, Redmi and POCO devices, what functions it performs beyond basic protection, and how to configure it for specific tasks. We will focus on hidden features that are not mentioned in the official instructions, but can greatly simplify the everyday use of a smartphone. If you want to turn your Xiaomi into a truly “smart” assistant, read on.
What is a lock screen and why do you need it?
The lock screen is the first interface you see when you turn on or wake up your smartphone, and its main purpose is to prevent unauthorized access to device data, but in MIUI, this element performs much more functions:
- 🔒 Data protection: blocking PIN-code, pattern lock, fingerprint or facial recognition.
- 📱 Quick access: Starting a camera, flashlight or voice assistant without unlocking.
- 🔔 Notifications: Viewing incoming messages, missed calls and alerts from apps.
- 🎨 Personalization: changing wallpaper, fonts, widgets and animations.
- 🔄 Interactivity: gestures, double touch to wake up, lift to unlock.
Interestingly, in recent versions of MIUI 14/15, the lock screen has also become a platform for smart home widgets, such as the ability to place the Xiaomi Smart Home buttons or display the weather in real time, all of which work even when the main screen is off – just swipe your finger in the right direction.
It is important to understand the difference between a lock screen and a screensaver, the first one appearing when you press the power button or timeout, and the second one when the device is connected to charge in Always On Display mode (if supported), the two elements are set up independently of each other.
Types of screen lock on Xiaomi: from PIN to biometrics
Xiaomi smartphones support several lock-in methods, each with its own pros and cons. The choice of method depends on the balance between convenience and security.
