The fastest way to change your wallpaper

On most phones, you change the wallpaper by opening Settings, finding Display or Home Screen, and selecting a new image from your phone's built-in gallery or from photos you have taken. The exact path depends on whether you have an iPhone or Android phone, and which version you are running, but the principle is the same: the phone stores wallpaper settings in one place, and you point it to a different image file.

You do not need to read anything or restart your phone. The change takes effect when ready, and you can switch back to your old wallpaper at any time by following the same steps.

Key Takeaways

  • On iPhone, open Settings, tap Wallpaper, then choose Add New Wallpaper and select a photo from your library or use a built-in design.
  • On Android, open Settings, find Display or Home Screen (the name varies by manufacturer), and select Wallpaper to pick a new image.
  • You can use any photo stored on your phone, or choose from the pre-loaded wallpapers that came with your device.
  • Changing your wallpaper does not affect your apps, files, or phone performance in any way.

How to change wallpaper on iPhone

Open the Settings app and scroll down until you see Wallpaper. Tap it. You will see your current lock screen and home screen wallpapers displayed at the top.

Tap the button that says Add New Wallpaper or the plus icon. The phone will show you two options: Featured (Apple's built-in designs) or Photos (images from your camera roll or photo library). Choose whichever you prefer. If you pick Photos, scroll through your library and tap the image you want. If you pick Featured, scroll through Apple's collection and tap one that appeals to you.

After you select an image, the phone will ask you whether you want to set it as your lock screen wallpaper, home screen wallpaper, or both. Make your choice and tap Set. The change happens when ready.

How to change wallpaper on Android

Open the Settings app. The next step depends on your phone's manufacturer. Look for an option called Display, Home Screen, or Wallpaper. Samsung phones usually have it under Display. Google Pixel phones usually have it under Display as well. Other manufacturers may place it elsewhere, so if you do not see it in Display, try searching for "wallpaper" in Settings using the search bar at the top.

Once you find the Wallpaper option, tap it. Android will show you a list of sources: Gallery (your photos), Wallpapers (built-in designs), or sometimes Live Wallpapers (animated backgrounds). Choose Gallery if you want to use a photo you took, or Wallpapers if you want one of the phone's pre-loaded designs.

Select the image you want and tap Set Wallpaper. You may be asked whether you want to set it for your home screen, lock screen, or both. Choose your preference and confirm. The wallpaper changes right away.

Using photos from your camera roll

Any photo you have taken or saved on your phone can become your wallpaper. When you choose the Gallery or Photos option during the wallpaper-change process, you are browsing the same folder where your camera stores pictures.

If you want to use a photo that is not yet on your phone, you will need to save it first. You can do this by downloading an image from the internet (long-press the image and select Save), or by transferring photos from your computer using a cable or cloud service like Google Photos or iCloud.

Once the photo is on your phone, follow the wallpaper-change steps above and select it from your photo library. The phone will let you crop or zoom the image before you confirm, so you can frame it the way you want.

Built-in wallpapers that came with your phone

Every phone includes a collection of wallpapers designed by the manufacturer. On iPhone, these are in the Featured section. On Android, they are usually in a Wallpapers app or a Wallpapers section within Settings.

These built-in designs are optimized for your phone's screen size and colors, so they often look sharper than random images you find online. They also do not take up extra storage space the way a large photo would. If you are not sure what you want, starting with the built-in collection is a safe choice.

Animated and live wallpapers on Android

Android phones can use animated wallpapers that move or respond to touch. These are called Live Wallpapers. To use one, open Settings, find Wallpaper, and look for a Live Wallpapers option. Tap it and choose an animation you like.

Live wallpapers use slightly more battery than static images because your screen is constantly drawing movement. If you notice your phone's battery draining faster after you set a live wallpaper, you can always switch back to a regular image by following the same steps.

Troubleshooting if the change does not work

If you set a new wallpaper and it does not appear, restart your phone. Power it off completely, wait a few seconds, and turn it back on. This clears the phone's memory and forces it to reload the wallpaper.

If the wallpaper still does not change, check that you have enough storage space on your phone. Go to Settings and look for Storage or About Phone to see how much space is free. If your phone is nearly full, delete some old photos or videos and try again.

On Android, if the Wallpaper option is missing from Settings, try opening the Wallpapers app directly from your app drawer. Some manufacturers bundle wallpaper settings into a separate app rather than putting them in Settings.

Frequently Asked Questions

Can I use a screenshot as my wallpaper?

Yes. Screenshots are saved to your photo library just like any other image. Take the screenshot, then follow the wallpaper-change steps and select it from your Photos or Gallery. You can crop it to fit your screen before you confirm.

Will changing my wallpaper delete my apps or files?

No. Your wallpaper is purely visual and does not touch anything on your phone. All your apps, photos, messages, and data remain exactly as they were.

Can I set different wallpapers for my lock screen and home screen?

Yes. Both iPhone and Android let you choose separate images for each. When you set a new wallpaper, the phone will ask you which screen you want to change, or give you the option to set it for both at once.

What size should my photo be to use as a wallpaper?

Your phone will automatically crop or resize any photo to fit your screen, so the exact size does not matter. Larger photos (from a camera or high-resolution source) will look sharper than small images, but any photo will work.

Can I go back to my old wallpaper?

Yes. Follow the same steps to change your wallpaper and select the old image again. If you cannot remember what it was, you can always pick one of the built-in designs that came with your phone.
