Android Wallpaper Keeps Changing? How to Stop It (2026)

You set a picture you like, and the next morning the lock screen shows a mountain lake you have never seen, or the phone is back on the factory wallpaper. Nothing is broken. In almost every case one of two things happened: a feature is rotating images on purpose, or the phone dropped your wallpaper and fell back to the default.

Both have a clear fix. Below is where to look on Samsung, Xiaomi, Redmi, Poco, Pixel and other Android phones, in the order that solves the problem fastest.

Why does my Android wallpaper keep changing?

Start by watching what changes. The pattern points straight at the cause.

• A new photo on the lock screen every day or every time you wake the phone, often with a headline or a "learn more" link: a lock screen content service such as Glance, Dynamic Lock Screen, Samsung Global Goals or Wallpaper Carousel.
• A new image once a day on the home screen and lock screen: a daily wallpaper option in the system wallpaper app or in a launcher.
• Your wallpaper is replaced by the factory one: a live wallpaper app was stopped, a trial theme expired or a system update reset the theme.
• The same picture, only darker at night: not a change at all, but dark mode or bedtime mode dimming it.

Samsung: Dynamic Lock Screen, Global Goals and Glance

On Galaxy phones the usual culprit is a wallpaper service attached to the lock screen. Samsung offers Dynamic Lock Screen, which downloads a new photo from a theme you picked, and Samsung Global Goals, which shows illustrated cards. In some countries, including India, Glance is offered as well.

1. Open Settings and tap Wallpaper and style. On older One UI versions the same item sits under Lock screen.
2. Tap Wallpaper services.
3. Choose None.
4. Go back, tap Change wallpapers and set your own picture on the lock screen again.

If the switch to None does not stick, check the Galaxy Themes app. A paid theme on trial returns the phone to the default theme, wallpaper included, when the trial ends. Our guide to the Samsung lock screen wallpaper walks through the rest of the One UI lock screen settings.

Xiaomi, Redmi and Poco: Wallpaper Carousel and Glance

Xiaomi phones ship with a rotating lock screen feed. Depending on the region and the version of MIUI or HyperOS it is called Wallpaper Carousel or Glance.

1. Open Settings and tap Lock screen.
2. Look for Wallpaper Carousel or Glance and turn it off.
3. If it is not there, open the Wallpaper Carousel or Themes app itself and switch it off in its own settings.
4. Set your wallpaper again from Settings, Wallpaper.

Other brands use the same idea under other names. Oppo, Realme and Vivo have offered Glance or a lock screen magazine in some markets. In Settings, search for "lock screen", "magazine" or "Glance" and switch off anything that pulls in new pictures.

Pixel and other phones: daily wallpaper and launchers

On a Pixel, open Wallpaper & style and check whether one of Google's collections is set as a daily wallpaper. That option swaps the image once a day. Pick a single image, or your own photo, and the rotation stops.

Third-party launchers can do the same. Microsoft Launcher, for example, offers a daily Bing image. Check the wallpaper section of your launcher's settings, and remove any wallpaper changer app you installed and forgot about. If you are not sure which app is in charge, set the wallpaper from the system menu as described in how to set a wallpaper on Android.

Phones managed by an employer or a school can also have the wallpaper fixed by policy. In that case only the administrator can change it.

Why Android resets your wallpaper to default

When the phone goes back to the stock picture rather than a new one, it usually lost the source of your wallpaper.

• A live wallpaper app was stopped. A live wallpaper is an app running in the background. If battery saving kills it, or you update or uninstall it, Android falls back to the default. Set the app's battery usage to Unrestricted, or switch to a still image.
• A theme expired or was reset. Trial themes and some system updates restore the default theme together with its wallpaper.
• Restoring from a backup. A new phone or a reset phone may restore your apps but not your wallpaper.

A still image set from the system menu is the most stable choice. Android keeps its own copy, so it survives restarts and battery saving.

Lilac Shore, Alpine Blush and Saltwater Moon are still images at 2160 × 3840 pixels, so once they are set nothing in the background can swap or drop them.

Wallpaper looks darker at night: dark mode and bedtime

If the picture is the same but dimmer in the evening, two settings are at work. Samsung can apply dark mode to the wallpaper: in Wallpaper and style, turn off the option that applies dark mode to the wallpaper. On Pixel and other phones with Digital Wellbeing, Bedtime mode can dim the wallpaper or switch the screen to greyscale; open Digital Wellbeing, Bedtime mode, Customize and turn off Dim the wallpaper.

If the image looks enlarged rather than darker, that is a different issue, covered in why an Android wallpaper looks zoomed in.

How to keep one wallpaper for good

Once the rotation is off, set a single still image from Settings, Wallpaper, and choose both the home screen and the lock screen, or a different picture for each. Use a file at least as tall as your screen; our Android wallpaper size guide lists real resolutions.

Velpaper phone wallpapers are original still images at 2160 × 3840 pixels, larger than any current Android screen, so Android only scales them down. Save one from the Android app or from its page on velpaper.com, then set it from the gallery.

Calm pictures such as Blue Cove or Rain Kept also make the clock and notifications easy to read, which is the other reason people turn off the noisy lock screen feeds in the first place.
