The lock screen is the first thing you see when you turn on your smartphone, and many users want to personalize it by setting their favorite photo instead of the standard wallpaper. However, not everyone knows that Android you can not only change the desktop background, but also customize the image on the lock screen separately. Depending on the version of the operating system and the device manufacturer (Samsung, Xiaomi, Google Pixel, Huawei etc.), the process may differ - in some places this is done in two clicks, and in others it requires workarounds.

In this article we will examine all current methods installing a photo on the lock screen, including hidden settings, third-party applications and even manual methods for advanced users. You will learn how to avoid image cropping, why some pictures are not displayed correctly, and what to do if the system does not allow you to change the lock background. And also - how to make your photo look perfect on any screen, from HD+ to 4K.

1. Standard method: through Android settings

Most modern smartphones on Android 10 and later allow you to change the background of the lock screen directly from the settings menu. This method is the simplest and does not require installing additional applications. However, the interface may differ depending on the manufacturer’s shell - One UI (Samsung), MIUI (Xiaomi), ColorOS (Oppo/Realme), etc.

General scheme of actions:

  • 📱 Open the application Settings (icon gears in the menu or on the desktop).
  • 🎨 Find the section Wallpaper, Lock screen or Personalization (on some devices it may be called Themes).
  • 🖼️ Select an option Screen wallpaper locks (sometimes it is combined with desktop wallpaper).
  • 📁 Click My photos or Gallery, then select the desired image.
  • ✅ Confirm your choice and save changes.

On some devices (for example, Samsung Galaxy s One UI 5.0+), you can separately configure the background for lock screen and desktop. If there is no such option, the system will automatically apply the selected photo to both screens.

📊 Which Android shell are you using?
One UI (Samsung)
MIUI (Xiaomi/Redmi)
ColorOS (Oppo/Realme)
Stock Android (Pixel/Motorola)
Other
⚠️ Attention: On some budget smartphones (for example, Tecno, Infinix), the option to change the lock background may be blocked by the manufacturer. In this case, use the methods from the following sections.

2. Separate setting of the lock and desktop background

Many users want to have different wallpaperson the lock screen and desktop. Unfortunately, not all versions of Android support this function out of the box. shells:

Manufacturer Shell version Is separate setting supported? How to enable
Samsung One UI 4.0+ Yes Settings → Wallpaper → Select "Lock screen" separately
Xiaomi/Redmi/Poco MIUI 12+ Yes (only for some themes) Themes → My wallpaper → Additional settings
Google Pixel Stock Android 12+ No Requires third party Software (see section 4)
Huawei/Honor EMUI 11+ Yes Settings → Screen and wallpaper → Wallpaper settings

If your device does not support separate settings, you can use a workaround:

  1. Install wallpaper on your desktop.
  2. Take a screenshot of the lock screen (usually Volume down + Power).
  3. Edit the screenshot in any graphic editor (for example, PicsArt or Photoshop Express), placing your photo on top.
  4. Set the resulting image as the lock wallpaper through the standard settings.
💡

If you want only photos without widgets (weather, notifications) to be displayed on the lock screen, disable them in the settings: Settings → Lock screen → Lock style → Without widgets (item name may vary).

3. Why is the photo cropped or looks blurry?

One of the most common problems when setting a photo on the lock screen is incorrect cropping or loss of qualityThis happens because Android automatically adjusts the image to the resolution. screen and the location of interface elements (clock, notification icons, etc.).

To avoid this, follow the rules:

  • 📏 Keep the screen proportions. Find out the resolution of your display (for example, 2400×1080 for Full HD+) and crop the photo in advance in the editor.
  • 🔍 Avoid important details edges. Android can crop up to 10-15% of the image on each side.
  • 🎨 Use high resolution. Minimum quality - 1920×1080 (for Full HD), but it is better to take a photo with a reserve (for example, 3840×2160 for 4K).
  • 🖼️ Save in PNG format. It supports transparency and compresses images less than JPEG.

On devices with a cutout for the front camera (for example, Samsung Galaxy S23 or Xiaomi 13), Android can automatically move the photo down so as not to cover the sensors. To avoid this, add a black stripe ~100 pixels high at the top of the image - it will disappear under the cutout.

How to find the exact screen resolution of your smartphone?

To find out the screen resolution, go to Settings → About phone → Device characteristics (or Information about Software). there is no information there, install the application AIDA64 or CPU-Z —in the section Display the exact resolution will be indicated (for example, 2400 × 1080).

5. Manually changing wallpaper through the file system (for advanced)

If your device rooted (has rights root), you can manually change the standard lock wallpaper by overwriting system files. This method is suitable for custom firmware (for example, LineageOS) or if the manufacturer has blocked changing backgrounds.

Instructions:

  1. Download and install a file manager that supports root (for example, Root Explorer or Solid Explorer).
  2. Go to the path: 
    /data/system/users/0/

    Wallpaper files may be located here (usually with the extension .jpg or .png and names like wallpaper_lock).

  3. Copy your photo to this folder, renaming it in accordance with the name of the standard wallpaper file.
  4. Change the access rights to 644 (read for everyone, write - only for owner).
  5. Reboot the device.

If the folder /data/system/users/0/ is empty or there are no wallpaper files there, try searching in:

/data/data/com.android.systemui/files/

/system/priv-app/SystemUI/
⚠️ Attention: Incorrect modification of system files can lead to interface crash or load looping. Before experiments, make a backup copy of your data via TWRP or ADB.

  2. Open the application and select a template (or create your own).
  3. Customize animation, colors and elements (for example, add a clock on top background).
  4. Save the preset and apply it as a lock wallpaper.
⚠️ Attention: Live wallpapers and widgets on the lock screen can increase battery consumption by 5-15%. If you notice that your smartphone is starting to discharge faster, return to static wallpaper.
