There are a few potential reasons why your phone’s wallpaper may have changed on its own:
Software update
Sometimes a software update can cause changes to your phone’s settings, including the wallpaper. When you update your phone’s operating system or apps, it’s possible for the wallpaper to get reset. Check if you recently installed any updates on your phone around the time the wallpaper changed.
Bug or glitch
It’s also possible a bug or glitch could have caused your wallpaper to change. Bugs in the operating system software can sometimes mess with settings and cause unintended changes. If this seems to be an isolated case, a bug may be the culprit. Try restarting your phone to clear out any glitches.
Prank or prank app
Someone who has access to your phone, like a friend or family member, may have changed your wallpaper as a prank. There are also prank apps they could have downloaded that can automatically change wallpaper. Check with anyone who may have had your phone recently and look for any unfamiliar apps.
Wrong settings
You may have accidentally set your wallpaper to change automatically without realizing it. Look in your phone’s settings or wallpaper options for a setting like “change wallpaper periodically” or “randomize wallpaper” and turn it off. This could be changing your wallpaper without you knowing.
Troubleshooting Steps
If you’re still unsure what caused your wallpaper to change, there are some troubleshooting steps you can take:
Check recent activity on your phone
Look at any recently downloaded apps or updates around the time your wallpaper changed. Also look for any recently changed settings that could be related. This might give clues to what altered your wallpaper.
Scan for malware
While less likely, malware or viruses could also change your wallpaper. Scan your phone with antivirus software to check for any infections. Malware may also change settings as part of malicious activity.
Restore to previous version
Some phones let you restore to a previous version or backup from before the wallpaper change. If you have a backup from right before the issue, restoring can revert your phone to when the wallpaper was still normal.
Factory reset your phone
If nothing else has worked, doing a factory reset will wipe your phone back to default settings. Make sure to backup any important data first. A reset should erase any problematic software or bugs causing the wallpaper issues.
Preventing Future Occurrences
To help prevent your wallpaper from changing unexpectedly again in the future:
Be cautious with downloads
Only download apps from trusted sources like the official app store for your phone’s operating system. Avoid any suspicious downloads that could change settings or infect your phone with malware.
Keep your software updated
Install regular operating system and app updates which often include security patches. Out of date software is more vulnerable to bugs and glitches.
Use antivirus software
Antivirus software can detect and remove malware that may change your wallpaper or settings. Scan your phone regularly to catch any infections before they cause harm.
Set wallpaper to not change automatically
Double check your wallpaper settings and turn off any options that allow periodic changing or randomization of the wallpaper image. Keep it set to a static image.
Set a password or fingerprint lock
To prevent pranks, make sure you phone has a secure screen lock like a password, pin, pattern or fingerprint lock. This prevents unauthorized access to your phone.
When to Get Help
In some cases you may need additional help if you cannot determine the cause or the wallpaper continues changing:
Contact mobile carrier support
Your phone’s mobile carrier may be able to offer technical support, especially for issues related to the operating system or network. They can also check for any known bugs.
Visit a device repair shop
A phone repair technician can do diagnostic tests to identify any problems with software or hardware that may be affecting the wallpaper. They may find issues you cannot detect yourself.
Use phone manufacturer support
The manufacturer of your phone likely offers technical support through phone, chat or forums. They can help troubleshoot issues specific to your phone model and operating system.
Post in online forums
There are many active forums and communities online for mobile tech support. Describe your wallpaper issue and see if other users have experienced and solved the same problem before.
