Updating to Android 12 brought not only changes in security and performance, but also significantly transformed the visual style of the operating system. One of the main innovations was the Material Youfunction, which allows the interface to adapt to the colors of your wallpaper. This makes the process of personalizing the device deeper and more meaningful than just choosing a beautiful picture.
Many users, when faced with the new settings menu for the first time, may get confused and not find the usual options. Google has redesigned the section structure, combining some parameters and taking others to a new level. In this material, we will look in detail at how to change the background of the desktop and lock screen, using both standard system tools and third-party solutions.
Regardless of whether you own a smartphone Pixel, Samsung or a device from Xiaomi, the basic principles of installing images remain similar, although the paths in the menu may differ slightly. We will look at all available methods so that you can fully unleash the potential of your gadget and make its appearance unique.
Standard method through system settings
The most reliable and universal method of changing the background is to use the built-in settings menu. This path ensures that the image will be displayed correctly both on the home screen and on the lock screen without unnecessary manipulations with access rights.
First, unlock your device and find the icon Settingswhich usually looks like a gear. In the list of options that opens, you need to scroll down to the Wallpaper and stylesection. In some shells, for example One UI from Samsung, this item may be called simply Wallpaper and be at the very top of the list.
⚠️ Attention: In pure Android 12, choosing a wallpaper automatically changes the color palette of system widgets and buttons. If you select a very bright or contrasting image, interface elements may become less readable.
By clicking on the desired section, you will be taken to a gallery of preset images. The system offers several categories: basic wallpapers, live wallpapers, and often a collection from partners, such as Google Arts & Culture. Select the image you like and press the button Set wallpaper at the bottom of the screen.
After selection, the system will prompt you to define the display area. You can move and scale the image to highlight the desired detail. Next, a menu will appear with three application options: install only on the main screen, only on the lock screen, or on both screens at once.
☑️ Correct installation of wallpaper
Quick change via the desktop
For those who value time and prefer to minimize the number of menu transitions, Android developers have provided a faster method. This method allows you to change the background in just a couple of touches, without going into the depths of system settings.
Unlock your smartphone and go to any free area of the desktop where there are no application icons or widgets. Make a long press with your finger on an empty area of the screen. After a second, a quick access panel with several options will appear at the bottom.
Among the available actions you will see the items “Widgets”, “Home Screen” and Wallpaper. Click on the wallpaper icon, and the system will immediately take you to the image selection menu. This method is identical in functionality to the first method, but saves a few seconds of navigation.
If you have a launcher installed from a third-party developer, for example Nova Launcher or Lawnchair, a long press can bring up the menu of this particular launcher. In this case, the functionality of changing wallpaper can be expanded or, conversely, limited depending on the settings of a particular application.
Installing an image from the Gallery
Often users want to see their own photos on the screen: nature shots, portraits of loved ones or travel shots. Android 12's standard gallery makes it easy to set any saved image as the background. Open the app and find the photo you want. Click on the image to open it full screen, then find the additional options menu. It is usually indicated by three dots in the corner of the screen or an icon with three vertical dots.
Open the application Gallery or Google Photos and find the photo you want. Click on the image to open it full screen, then find the additional options menu. It is usually indicated by three dots in the corner of the screen or an icon with three vertical dots.
In the drop-down list, select Set as wallpaper. The system will offer to crop the image to fit the screen proportions, since photos from cameras often have an aspect ratio different from the smartphone display. After confirmation, you can choose where to apply the picture.
Use photos with a resolution of at least 1080x2400 pixels to avoid blurring and loss of quality when stretched to fill the entire screen.
It is worth considering that when installing a photo from the gallery, the function Material You will still work. The system will analyze the dominant colors in your photo and adjust the color of the clock on the lock screen and the shade of the notification bar to match them.
| Image source | Advantages | Disadvantages |
|---|---|---|
| System gallery | Optimized for screen, high speed | Limited selection of styles |
| Personal photos | Uniqueness, emotional value | Cropping may be required |
| Third-party applications | Huge selection, 4K quality | Battery load, advertising |
Customizing live wallpapers and saving energy
Live wallpapers (Live Wallpapers) are animated scenes that respond to touches or movement of the device. In Android 12, they have become smoother and visually pleasing, but their use has its own characteristics.
To set an animated background, go to the wallpaper settings and select a category Live Wallpapers. Here you will find classic options such as Waterfall or Planets, as well as special versions created for the new version of the OS. Some wallpapers may change their appearance depending on the time of day.
⚠️ Attention: Active live wallpapers consume significantly more battery power than static images. If you notice that your smartphone is quickly draining, try disabling this feature.
In the settings of specific live wallpapers, you can often change the animation speed or disable movement when the phone is in power saving mode. This allows you to maintain the visual effect, but reduce the load on the processor and battery at critical moments.
Impact on performance
Modern smartphone processors can easily cope with rendering live wallpapers, but on budget models this can cause micro-stuttering when swiping across the desktop.
Also worth it remember the Wallpaper when touchedfunction, which is available on some devices. It activates the animation only when you hold your finger on the screen, saving resources the rest of the time. This is a compromise solution for lovers of dynamics.
Personalization through Material You
Function Material You (or “Themes” in some shells) is the hallmark of Android 12. It doesn’t just change the picture, but rebuilds the entire visual language of the interface, creating a harmonious environment.
When selecting new wallpaper, the system automatically generates a color palette. These colors apply to switch buttons in the notification shade, clock widgets, calendar widgets, and even some elements inside supported apps, such as Google Calendar or Google Calendar Contact.
If you don't like the automatic color selection, you can manually adjust the palette. Go to the Wallpaper and stylesection, select Color palette and disable automatic mode. Here you can choose one of four preset color sets or customize them manually.
Material You makes the interface holistic: wallpaper is no longer just a background, but becomes a source of style for all system controls.
This technology looks especially impressive on devices with AMOLED screens, where the deep colors of the palette look rich and bright. By experimenting with different images, you can completely change the mood of your smartphone in a couple of seconds.
Using third-party applications
If a standard set of images is not enough for you, the store Google Play offers thousands of specialized applications for setting wallpaper. apps such as Wallpaper Engine, Zedge or Backdropsprovide access to high-quality content.
Aggregator applications often offer categories that are not in the system: abstraction, minimalism, anime, cars and much more. Many of them support downloading wallpapers in 4K resolution and higher, which is ideal for modern displays with high pixel density.
However, you should be careful when installing third-party software. Some apps may request excessive permissions or display intrusive ads. It is recommended to choose apps with a high rating and a large number of downloads.
Before installing a wallpaper application, check its permissions in the Android settings. It shouldn't require access to your contacts or microphone to operate.
Some advanced utilities allow you to set different wallpapers for different desktops or create a slideshow that changes every few hours. This gives maximum flexibility in customizing the appearance of the device.
⚠️ Attention: Settings interfaces may vary depending on the smartphone manufacturer. If you do not find the described menu item, use the search inside the settings for “Wallpaper.”
Frequently asked questions
Why does the wallpaper look blurry after installation?

Is it possible to set a video as wallpaper?
You cannot install a video file directly using standard Android 12 tools, only special live wallpapers. However, there are converter applications that turn the video into a live wallpaper format, allowing you to play the video on the desktop background.
How to return the standard Google wallpaper?
Go to settings Wallpaper and style, select the category of basic wallpapers and find original Android 12 images there. They are usually located at the beginning of the list or in a separate folder “System.”
Does the dark theme affect the perception of the wallpaper?
Yes, turning on the dark theme can change the contrast of some interface elements on top of the wallpaper, but the image itself remains unchanged. However, the Material You feature can adjust the colors of widgets to better match the dark mode.
Where are the installed wallpapers stored in the phone's memory?
System wallpapers are stored in a secure section of the system. Wallpaper installed from the gallery remains in the place where you saved the original photo. Wallpaper applications usually cache images in their own folder inside the internal storage.
