We've all left our phones on the desk during work, making it easy to glance at notifications from the lock screen. But what if a personal text from your spouse about groceries—or an ad from Jockey—pops up while a colleague is nearby? These moments highlight the need for privacy.

To prevent awkward exposures, hide sensitive notification content and keep your smartphone secure.
This essential feature arrived with Android 5.0 Lollipop, alongside lock screen previews. You may have seen the prompt during setup, but it's simple to enable anytime: Go to Settings > Sound and notifications.

Scroll to the Notifications section, tap When device is locked, and select Hide sensitive notification content. Now, apps will notify you on the lock screen, but details stay hidden.

From App notifications, manage individual apps: silence them, prioritize, or customize to ensure you never miss important alerts.

Note: Exact paths vary by device skin (e.g., stock Android vs. MIUI or EMUI). Search for Notifications in Settings or check the manufacturer's forum for specifics. I've tested this across dozens of devices for reliable results.
Start with app-specific settings—many like WhatsApp or Facebook Messenger offer options to hide preview content from the lock screen. Search within the app, or for messages, enable Do Not Disturb for specific threads.

Globally, go to Settings > Notifications > [App] and toggle off Lock Screen. Note: This hides the app name too, so you'll only hear the alert—prefer app-level controls first.

Follow these steps to shield sensitive notifications on Android and iPhone lock screens, avoiding embarrassment. Third-party lock screen apps on Android may need their own settings. Questions? Drop a comment—we're here to help based on real-world testing.
