Android Lock Screen Showing Ads: Why It Happens & How to Remove Them
Table of Contents
Introduction
If you’ve recently noticed ads popping up on your Android lock screen, you’re not alone—and you’re definitely not imagining things. This is a common issue caused by certain apps, especially free ones that sneak in ad-serving features.
These ads are not a built-in feature of Android. In almost all cases, they come from third-party apps you’ve installed. The good news? They’re usually easy to identify and remove.
Let’s break down why it happens and exactly how to get rid of them.
Why Ads Appear on the Android Lock Screen
Android itself does not display ads on the lock screen. If you’re seeing them, they’re being injected by:
-
📱 Free apps with aggressive ad models
-
🎨 Lock screen customization apps
-
🔦 Utility apps (flashlight, battery saver, cleaner)
-
🎮 Games offering rewards for ad views
These apps typically request permission to appear over other apps, which lets them show ads even when your screen is locked.
Common Apps That Cause Lock Screen Ads
Based on user reports, here are some app categories and names frequently linked to lock screen ads:
| App Type | Examples |
|---|---|
| Weather apps | Weather Home, Weather Forecast |
| Utility tools | DU Battery Saver, Clean Master |
| Lock screen apps | Hi Locker, CM Locker |
| Launchers | GO Launcher, Cheetah Mobile apps |
| Music apps | Music Player - Free Music (generic) |
| File managers | ES File Explorer (older versions) |
These apps might work as advertised—but they make money by pushing intrusive ads.
How to Identify the App Showing Ads
Here’s how to find out which app is causing the issue:
🔍 Method 1: Check Recently Installed Apps
-
Go to Settings → Apps → Recently Installed
-
Look for apps installed around the time the ads started
-
Pay attention to apps you don’t remember installing
🧱 Method 2: Check Apps with “Draw Over Other Apps” Permission
-
Open Settings → Apps & notifications → Special app access
-
Tap Display over other apps
-
Look for apps with permission enabled
-
Disable it for suspicious apps
📊 Method 3: Use Google Play Protect
-
Open the Play Store
-
Tap your profile → Play Protect
-
Run a Scan
-
If an app is malicious or ad-serving, Play Protect may flag it
How to Remove Ads from the Lock Screen
✅ Option 1: Uninstall the Offending App
Once identified, long-press on the app icon or go to Settings → Apps → [App Name] → Uninstall
✅ Option 2: Revoke Display Permissions
If you’re not ready to uninstall:
-
Go to Settings → Apps → Special access → Display over other apps
-
Turn OFF permission for the app causing ads
✅ Option 3: Disable Lock Screen Ads (OEM-Specific)
Some manufacturers like Xiaomi or Infinix may include ads in their OS by default.
For Xiaomi (MIUI):
-
Go to Settings → Passwords & security → Lock screen
-
Turn OFF Glance for Mi (a common ad source)
Preventing Future Lock Screen Ads
To keep ads away permanently:
-
✅ Avoid installing APKs from unknown sources
-
✅ Read app reviews on Google Play—users often report if apps show ads
-
✅ Use reputable apps with high ratings and no unnecessary permissions
-
✅ Regularly audit apps and uninstall ones you don’t use
-
✅ Enable Google Play Protect for ongoing scanning
Trusted Apps to Avoid
Even legitimate apps can start pushing ads after an update. Be cautious with:
-
Apps with vague names or generic icons
-
Apps that request too many permissions (especially “draw over apps” or “lock screen access”)
-
Apps that change your wallpaper or lock screen without permission
Conclusion
Seeing ads on your Android lock screen is not normal, and it's usually the result of a misbehaving app that has slipped through your app list unnoticed. The key is to identify and uninstall the culprit—and adjust permissions so this doesn’t happen again.
By staying cautious with the apps you install and knowing where to look when something feels off, you can keep your lock screen clean, professional, and ad-free.
