How to change the picture on the lock screen Xiaomi Redmi

Personalization of the interface is the first thing that the owner of a new smartphone wants to do to reflect his personality. Standard images preinstalled by the manufacturer often seem boring or simply do not correspond to the current mood of the user. In the shell of MIUI and its modern version of HyperOS, the process of replacing the background pattern is implemented quite flexibly, but has its own nuances that can confuse the beginner.

Many users find that once you install the desired image from the gallery, it does not apply or changes only on the desktop, leaving the lock screen unchanged. This is due to the separation of settings in the Android system, where the desktop background and lock screen are independently adjusted. Understanding this logic will allow you to quickly master visual design management.

In this article, we will discuss in detail all the available ways to replace static images, adjust the automatic wallpaper update through the wallpaper carousel service, and also touch on the issue of removing intrusive advertising that often appears on a locked screen. You will learn not only to change pictures, but also to fully control what you see whenever you turn on your smartphone.

Standard image replacement through system settings

The easiest and most reliable way to change the visual design is to use the built-in system settings menu, a method that is universal for most Xiaomi, Redmi and Poco models running current versions of Android. First, you need to unlock the device and find the Settings icon on your desktop, which usually looks like a gear.

After you enter the menu, you should scroll down to Wallpaper and personalization. Depending on the version of the MIUI shell, the name may vary slightly, but the essence remains the same. The system will offer you several categories: online gallery, static wallpaper and dynamic (live) screensavers. We are interested in static or downloading our file.

⚠️ Note: When selecting online wallpapers from Xiaomi’s directory, make sure you use a Wi-Fi connection, as high-resolution files can quickly consume mobile traffic.

If you select My Wallpaper or Local, you will be taken to the storage of your smartphone files, and you will need to find the folder where the desired image was saved (usually DCIM, Download or Pictures). Once you click on the file, the system will offer a preview and an Apply button. The key here is the right choice of application area, which will be discussed below.

Using the gallery for quick background installation

Often, users forget that the Gallery app has built-in functionality for quickly installing images as a background, a method that is much faster than finding the right file through system settings, especially if you just downloaded a picture from the Internet or received it in a messenger.

At the bottom of the screen or in the option menu (three dots in the corner), you need to find the button Another or icon with three dots. In the drop-down list will be the item Set as wallpaper. When you press it, the system automatically redirects you to the crop editor, where you can zoom in the image and choose which part of it to display on the screen.

Special attention should be paid to file formats. Modern Xiaomi smartphones work perfectly with formats. JPG and PNG, It's very high resolution, but if you set it up in a format, WEBP specific RAW-format, the system may offer conversion or incorrect color display. For best results, use images with a resolution of at least 1080×2400 pixel.

For AMOLED screens, use images with a predominance of black color - this significantly saves battery power and makes the interface more stylish.

Setting up wallpaper carousel and slideshow

One of the most popular features in the MIUI shell is the Wallpaper Carousel, which automatically changes the images on the lock screen every time you turn on your smartphone, and for many, it’s ideal because it eliminates the need to manually search and install new images by providing access to a huge database of high-quality photos.

To activate or customize this feature, go to Settings → Wallpaper → Wallpaper Carousel. Here you can choose the subject of the images: nature, cities, art, sports or celebrities. The system will select the content according to your preferences. You can also adjust the refresh rate and even allow video wallpaper downloads, if the tariff plan allows.

But there's a downside to this feature, and some users have noted that the carousel can consume extra battery power and Internet traffic in the background, and there are also images with logos or advertisements that can't be removed by standard means without turning off the feature itself.

Removal of advertising and promotional content in loxcrine

A separate and very important topic is the fight against intrusive advertising that can appear on the lock screen. Often users accidentally activate the Receive recommendations function during the initial setup of the smartphone or after the system update, resulting in news, banner ads and app offers appearing on the locked screen.

To get rid of this, you need to go back to the carousel settings. Find a switch called Receive recommendations or Turn on wallpaper carousel and deactivate it. In some firmware versions, this item may be hidden in the Settings section. → Passwords and security → System advertising, where you need to disable the item Get recommendations.

It's important to distinguish between ad units and just beautiful wallpaper from partners. If after disabling the recommendations, the images stopped changing, then you had a carousel that was active. If there are still application logos on the static background, try resetting the theme settings to standard ones through the Themes app.

⚠️ Note: Complete shutdown of system services through ADB-commands can lead to unstable interface operation. Use only the regular switches in the settings menu.

Working with live wallpaper and video backgrounds

Redmi’s modern 90Hz and 120Hz smartphone displays are ideal for displaying live wallpaper. This isn’t just a static picture, but a full-fledged animation or short video that is played when interacting with the screen or constantly.

There's a separate Wallpaper section in the Themes app where you can find video backgrounds, which can be free or paid. When downloading, make sure that the video is optimized for your screen resolution, otherwise you may have jerks when you're animation. Live wallpaper can be more battery-consuming, so on devices with a small battery, it's worth limiting their use.

You can also install your own video from the gallery as live wallpaper, but this will require special converter apps or widgets, since standard MIUI functionality often limits the choice to only system videos or content from the store. Popular applications like Video Live Wallpaper do this perfectly.

Comparison of installation methods and possible problems

The different ways you set up images have their pros and cons, which are worth considering depending on your goals. Below is a table to help you choose the best method for your situation.

A common problem is when the picture is stretched or cut incorrectly, and this is solved at the time of installation: during the preview stage, click on the framing setting icon (usually looks like a square with arrows) and select Screen size or Fill.

If after all the manipulations, the lock screen continues to display a standard plug or MIUI logo, perhaps the Tablet Mode or special mode function for children who block the change of design is activated.

💡

The optimal balance between beauty and energy efficiency is the use of high-quality static images in PNG format with a predominance of dark tones.
