Introduction

Are your Android phone notifications not appearing when the screen is locked? This can be frustrating—especially when you miss important messages, app alerts, or calls.

Don’t worry. In this post, you’ll find tested and simple fixes to solve the issue of "Android notifications not showing on lock screen". These methods work on Samsung, Xiaomi, OnePlus, Realme, and almost all Android devices.

 

1. Enable Lock Screen Notifications

Sometimes, this problem is due to lock screen settings being disabled.

Steps to Enable:

1. Go to Settings on your phone.

2. Tap on Notifications.

3. Select Lock Screen Notifications or On Lock Screen.

4. Choose Show All Notification Content.

Restart your phone and check if notifications now appear on the lock screen.

 

2. Check Lock Screen Security Settings

Your screen lock method can affect how notifications are shown. If your lock screen is set to hide sensitive content, then messages or alerts may not appear.

To Fix:

1. Go to Settings > Lock Screen > Notifications.

2. Set it to Show Content.

3. Also ensure Do Not Disturb is turned off (we'll explain below).

 

3. Turn Off “Do Not Disturb” Mode

If Do Not Disturb (DND) is on, notifications are blocked from appearing on the lock screen.

To Check and Turn Off DND:

1. Swipe down the quick settings panel.

2. Tap on Do Not Disturb to turn it off.

3. Or go to Settings > Sound > Do Not Disturb and turn it off.

Bonus Tip: Check if a schedule is set for DND. If yes, disable it or adjust the time.

 

4. Check App Notification Settings

Each app has its own notification settings. If you’re missing alerts from WhatsApp, Instagram, or other apps:

Steps:

1. Open Settings > Apps > [App Name] > Notifications.

2. Turn on Allow Notifications.

3. Check if Lock screen notifications are turned on.

4. Enable High priority notifications, if available.

 

5. Disable Battery Optimization for Important Apps

Android battery optimization can block apps from showing notifications when the screen is off.

To Disable Battery Saver for Apps:

1. Go to Settings > Battery > Battery Usage.

2. Tap on the affected app.

3. Tap Battery Optimization.

4. Select Don’t Optimize or Unrestricted (based on your phone model).

This ensures apps run properly in the background and push notifications correctly.

 

6. Check Background Data Usage

If background data is disabled for apps like Gmail, WhatsApp, etc., notifications won’t arrive unless the app is open.

Steps:

1. Go to Settings > Apps > [App Name] > Data usage.

2. Make sure Background data is turned ON.

3. Also enable Unrestricted data usage, if available.

 

7. Clear App Cache (For Buggy Apps)

Sometimes, old cache files block notifications from being delivered properly.

How to Clear Cache:

1. Go to Settings > Apps > [App Name].

2. Tap on Storage > Clear Cache.

This won’t delete your app data. But if the issue continues, you can also try Clear Data (login again afterward).

 

8. Restart Your Phone

A simple restart can fix temporary glitches in notification services.

Just Do This:

Hold the Power button > Restart.

After rebooting, check if notifications appear on the lock screen again.

 

9. Update Your Android System

Outdated software may contain bugs causing notification issues.

To Update:

1. Go to Settings > System > Software Update.

2. Tap on Check for updates.

3. Download and install any available update.

Updates often fix hidden bugs related to notifications.

 

10. Check Notification Categories (Android 10 & Above)

Apps like YouTube, Gmail, etc. now have notification channels. You must allow lock screen display for each type.

Steps:

1. Open Settings > Apps > [App Name] > Notifications.

2. Tap on each category (like Chats, Updates, Alerts).

3. Set them to Show on Lock Screen and Alert.

Bonus: Check if Notifications Are Being Blocked by Third-Party Apps

Some battery savers, cleaners, or antivirus apps silently block notifications.

To Fix:

1. Uninstall suspicious battery saver or cleaner apps.

2. Reboot your phone.

3. Check if notifications now work properly.

 

Why Do Notifications Matter on the Lock Screen?

You get real-time updates without unlocking your phone.

Saves time and improves productivity.

Critical alerts (banking, delivery, OTP) are never missed.
