How Do You Set a Video as Live Wallpaper on Android?
Use a video as an Android live wallpaper on the home screen or lock screen, with device-specific setup and cropping tips.
On Android, you may be able to set a local video directly from the Gallery or wallpaper picker. If your phone's software does not offer that option, use a well-reviewed video live-wallpaper app that accepts local MP4 files. Menu names vary across Samsung, Google Pixel, Xiaomi, OnePlus, and other brands, so start with the built-in route.
Try the phone's Gallery first
Open the downloaded video in your Gallery or Photos app. Open the menu and look for Set as wallpaper, Use as, or a wallpaper icon. Choose Home Screen, Lock Screen, or both if those choices appear. Preview the crop before applying it.
Some devices limit video length or only support video on the Lock Screen. Others accept a video for both screens. These are manufacturer rules, not a fault in the MP4. If no video-wallpaper command appears, long-press an empty area of the Home Screen, open Wallpaper & style, and check the Live Wallpapers category.
Use a local-video wallpaper app when needed
Install an app from Google Play or F-Droid whose listing clearly says it can use your own files. Review its permissions. A wallpaper player needs access to the chosen media, but it should not need contacts, SMS, or accessibility control just to display a video.
After installation, select the clip, choose crop or fit, turn on looping, and apply it through Android's wallpaper confirmation screen. Keep the file on internal storage. Removing an SD card, cleaning the Downloads folder, or revoking media access can leave the background blank.
Prepare a desktop-shaped video for a phone
Most Unique Live Wallpaper videos are 16:9 landscape files. A phone screen is tall, so a full-screen crop removes much of the left and right sides. Use fit mode if black space is acceptable, or create a vertical crop in a video editor. Place the most important radar, reticle, or interface element near the center before exporting.
H.264 MP4 is the safest starting format. A ProRes 4444 MOV is large and may not decode in an Android wallpaper service. Transparency also has little value when the clip is being used as the final background rather than composited over another image. Read the format comparison if the file does not appear in the picker.
Keep playback efficient
Animated backgrounds consume power while visible because the device must decode and draw frames. The effect depends on the phone, video, brightness, frame rate, and how long you remain on the Home Screen. A short 1080p 30 fps loop is generally easier to play than 4K 60 fps footage.
If the Home Screen scrolls poorly, export a smaller copy, disable wallpaper parallax, or choose a player that pauses when another app covers the screen. If the wallpaper stops under battery saver, check the player's battery settings before excluding it from optimization; an exclusion can increase background power use.
Finally, watch several repeats. Android can loop any supported clip, but it cannot hide a bad edit. A visible jump must be fixed in the video itself.
