Android Lock Screen Notifications Content Hidden: Why It Happens & How to Show It
Table of Contents
Introduction
If you're seeing the message “Content Hidden” or simply a notification title without its message on your Android lock screen, it’s not a bug—it's a privacy feature.
Android allows you to choose whether or not sensitive information appears when your phone is locked. Whether it’s texts, emails, or app notifications, Android can keep content private until you unlock the device.
But if you want full previews of your notifications on the lock screen—this guide will show you how to turn off "Content Hidden" and control how each app behaves.
What “Content Hidden” Means on Lock Screen
When Android notifications are set to “hide content,” you’ll typically see:
-
Just the app name (e.g., Messages or Gmail)
-
A generic preview like “1 new message” or “Content Hidden”
-
No actual message, sender name, or detail until the device is unlocked
This affects:
-
Text messages
-
Emails
-
Social media alerts
-
Banking and private notifications
Why Android Hides Notification Content by Default
This behavior is designed to protect your privacy in public or shared spaces.
Here’s why it may be enabled:
-
You turned on “Hide sensitive content”
-
Your device is managed by a workplace or admin policy
-
You activated Do Not Disturb with hidden previews
-
You’re using Face Unlock, and content is shown only after recognizing your face
How to Show Full Notification Content on Lock Screen
✅ Step 1: Check Global Notification Settings
For Most Android Phones:
-
Go to Settings → Notifications
-
Tap Lock screen notifications or Notifications on lock screen
-
Select “Show all notification content”
Alternate Paths:
-
Settings → Display → Lock Screen → Notifications
-
Choose “Show all content” (instead of “Hide sensitive content” or “Don’t show notifications”)
✅ Step 2: Disable Face Unlock Privacy (Optional)
Some Android versions (Pixel, OnePlus) hide content until your face is verified.
-
Go to Settings → Security → Face Unlock
-
Turn off “Only show notification content after face unlock”
App-Specific Notification Visibility Settings
Some apps (like Gmail, WhatsApp, or Signal) allow individual control over lock screen content.
Steps:
-
Settings → Apps → [App Name] → Notifications
-
Tap on the Notification category (e.g., Messages, Promotions, etc.)
-
Tap Lock screen or Notification visibility
-
Select “Show content” or “Show full notification”
Repeat for all apps you want full previews from.
Managing Sensitive Content Per App
If you want to keep most notifications visible but hide a few, you can manage this per app:
✅ For Example (Messages app):
-
Settings → Apps → Messages → Notifications
-
Choose the Messages category
-
Tap Lock Screen → Hide content
This way, you can still receive full previews from other apps while keeping texts private.
Troubleshooting: Content Still Hidden After Changes
If you've updated your settings and still see hidden content:
🔧 Try These Fixes:
-
