Turn Off Message Previews on Samsung Galaxy J7

This guide shows you how to stop message content from appearing on your Samsung Galaxy J7’s lock screen and status bar, so your private conversations stay hidden from prying eyes. You’ll learn to adjust the notification settings for both the default Messages app and other messaging apps like WhatsApp, all within a few minutes.

What You’ll Need

• Your Samsung Galaxy J7 (any model variant)
• Access to the Settings app (gear icon in the app drawer or notification shade)
• Optional: Your lock screen PIN, pattern, or password to verify changes

Step-by-Step

1. Open Settings. Swipe down from the top of your screen to open the notification shade, then tap the gear icon in the top-right corner. Alternatively, open the app drawer and tap the Settings app.
2. Navigate to Notifications. Scroll down and tap “Notifications” (or “Sound and notification” on some Android versions, then “Notifications”). This is the central hub for all app notification settings.
3. Select the Messages App. In the list of apps, find and tap “Messages” (the default Samsung messaging app). If you use a third-party app like WhatsApp or Facebook Messenger, you’ll repeat these steps for each app.
4. Turn Off Previews. Look for the option labeled “Show previews” or “Preview new messages.” Tap the toggle switch next to it to turn it off. On some J7 models, this might be under a submenu called “Lock screen” or “Notifications.”
5. Verify Lock Screen Settings (Optional). If you still see message content on the lock screen, go back to the main Settings menu, tap “Lock screen,” then “Notifications.” Here you can choose “Hide content” or “Don’t show notifications” for all apps at once. This is a stronger privacy measure.
6. Repeat for Other Messaging Apps. Go back to the Notifications list and select each messaging app you use (WhatsApp, Messenger, etc.). Turn off the preview toggle for each one individually. This ensures no app leaks message text.
7. Test Your Settings. Lock your phone and have someone send you a test message. The notification should now say “New message” or “1 new message” without showing the sender’s text or the message body.

Common Mistakes

• Only turning off previews for one app. If you use multiple messaging apps, you must disable previews in each one. The global lock screen setting can help, but app-specific settings override it.
• Disabling all notifications instead. Some users accidentally turn off the entire notification toggle, which means they no longer get any alerts for new messages. You want to keep notifications on but just hide the content.
• Checking the wrong lock screen setting. The J7 has a separate “Lock screen” notification setting that can show or hide content. If you only change the app-level setting, the lock screen might still display previews if the global setting is set to “Show content.”
• Not restarting after changes. Rarely, the settings may not apply immediately. A quick restart can force the new settings to take effect.

Tips

• Use “Hide content” for maximum privacy. On the lock screen notifications settings, choose “Hide content” instead of “Don’t show notifications.” This way you still get a notification that a message arrived, but the text is hidden until you unlock your phone.
• Set a secure lock screen. Even with previews off, anyone who unlocks your phone can read your messages. Use a PIN, pattern, or fingerprint to keep your phone secure.
• Customize per app. For apps like WhatsApp, you can often set previews to show only the sender’s name, not the message. Check the app’s own notification settings for more granular control.
• Use Do Not Disturb for quiet hours. If you want to avoid previews at night, schedule Do Not Disturb mode to silence notifications entirely during set hours.

Troubleshooting

• Previews still showing after turning them off. This usually means the app has its own notification settings that override the system. Open the specific app (e.g., WhatsApp), go to its Settings > Notifications, and disable “Show previews” there. Also check if the lock screen notification setting is set to “Show content” — change it to “Hide content.”
• Can’t find the preview option. On some J7 models with older Android versions, the option might be called “Notification preview” or “Preview.” Look under “Advanced” or “Detailed” settings within the app’s notification settings. If you still can’t find it, try updating your phone’s software via Settings > About phone > Software update.
• Changes revert after restart. This is rare but can happen if a system app is misbehaving. Try clearing the cache of the Settings app (Settings > Apps > Settings > Storage > Clear cache). If the problem persists, restart in Safe Mode (press and hold Power, then tap and hold “Power off”) to see if a third-party app is interfering.
• Notifications not appearing at all. If you accidentally turned off the entire notification toggle, re-enable it. Go to Settings > Notifications > Messages, and make sure the top toggle “Allow notifications” is on. You can then turn off just the preview option.

Frequently Asked Questions

Will turning off previews stop me from getting message notifications?

No. You will still receive a notification that a new message arrived, but the notification will not show the sender’s name or the message content. You’ll see something like “New message” instead.

Does this affect text messages only or also app messages like WhatsApp?

It affects each app individually. You need to turn off previews for the default Messages app and also for any third-party messaging apps you use. The steps are the same for each app.

Can I still see message content on the lock screen if I turn off previews?

No. Turning off previews stops the message content from appearing in the notification, including on the lock screen. However, if you have a lock screen widget or a separate notification setting that shows content, you may need to adjust that as well.

Will my phone still make a sound when I get a message?

Yes, the notification sound will still play unless you mute it. Turning off previews only hides the text content, not the alert itself.

What if I want to see previews for some apps but not others?

That’s fine. You can customize the preview setting per app. For example, turn off previews for the default Messages app but leave them on for WhatsApp if you prefer.

Do I need to turn off previews for each SIM card?

No. The notification settings are per app, not per SIM. If you have dual SIM, the same Messages app handles both, so the setting applies to both SIMs.
