You’re sitting at a crowded coffee shop. Your phone is on the table. Suddenly, a text from your bank or a sensitive DM from a friend pops up. It stays there. Everyone in line for a latte can see it. Honestly, it's a massive privacy hole that most of us just ignore because we want the convenience of seeing who’s calling without tapping the screen.
Managing how you display notifications on lock screen isn't just about hiding thirsty texts from your ex. It’s a legitimate security hurdle. Since the release of iOS 16 and recent Android 14/15 updates, the way our phones "talk" to us while locked has changed drastically. We’ve moved from simple banners to "Live Activities" and persistent widgets that leak way more data than you’d think.
The "Show Previews" Trap
Most people think they have two options: show everything or show nothing. That’s not true. Apple and Google have both tucked away a middle ground that almost nobody uses. It’s called "Show Previews when Unlocked."
On an iPhone, if you go to Settings > Notifications > Show Previews, you’ll see the "When Unlocked" option. This is the gold standard. It uses FaceID to verify it's actually you looking at the glass before it expands the "Hey, are you home?" text into the full message. If it’s anyone else, they just see the app icon and the word "Notification." It’s elegant. It works. Yet, millions of people leave it on "Always" because they don't want to deal with the extra half-second of authentication.
Android is a bit more fragmented because, well, it’s Android. If you're on a Pixel, the "Sensitive content" toggle is your best friend. It hides the body of the email or the chat while keeping the alert visible. Samsung’s One UI does something similar but hides it under "Lock screen" then "Notifications" then "Hide content."

Why does this matter? Because of "shoulder surfing." Cybersecurity experts like Kevin Mitnick used to talk about this all the time—the idea that the easiest way to hack someone isn't through code, it's just by looking over their shoulder. In 2026, your lock screen is the biggest target for that.
Smart Lock and the False Sense of Security
Here is where it gets kinda messy. Android has this feature called "Extend Unlock" (formerly Smart Lock). It keeps your phone unlocked if it’s on your person, at home, or connected to a "trusted" Bluetooth device like your car or watch.
While that’s convenient, it completely bypasses your privacy settings to display notifications on lock screen. If your phone thinks it’s "safe," it might show the full content of every notification to anyone who picks it up. You’ve basically traded your biometric security for the luxury of not typing a PIN.
I’ve seen people leave their phones on a gym bench while their watch is still in Bluetooth range. The phone stays unlocked. The notifications stay fully visible. It’s a disaster waiting to happen for anyone with sensitive work Slack channels or banking alerts.
The Rise of Live Activities
We need to talk about Live Activities. This is a relatively new way to display notifications on lock screen that doesn't just show a static message—it shows a living, breathing widget. Think Uber rides, Starbucks orders, or sports scores.

The problem? These bypass standard "hide content" rules often. Because they are designed to be "helpful," they frequently show your exact location or the specific items you ordered. On iOS, you can actually turn these off specifically without killing standard notifications. Go to Settings > Face ID & Passcode and toggle off "Live Activities" under the "Allow Access When Locked" section.
It’s worth doing.
Does a random person at the airport need to see your Uber driver's license plate and how many minutes away they are? Probably not.
Digital Wellbeing or Digital Distraction?
There is a psychological cost to how we display notifications on lock screen. Every time that screen lights up, your brain gets a hit of cortisol. Even if you don't read the message, the "glow" is a distraction.
Researchers at the University of California, Irvine, famously found that it takes about 23 minutes to get back into "deep work" after a distraction. If your lock screen is constantly pulsing with Instagram likes or news alerts, you are never actually in deep work. You’re in a state of "continuous partial attention."
I’ve started using "Scheduled Summary" on my iPhone. It’s a lifesaver. Instead of 50 pings throughout the day, I get one big bundle of notifications at 8:00 AM and 6:00 PM. The lock screen stays dark. My brain stays quiet. It’s honestly the best thing Apple has added to the OS in five years, yet most users haven't even touched the setup wizard for it.
The "Silent" Notification Hack
If you don't want to go nuclear and turn everything off, use "Deliver Quietly" (iOS) or "Silent" (Android).
This is the middle path. The notification still happens. It’s still there when you swipe down. But it doesn't make a sound, it doesn't vibrate, and it doesn't display notifications on lock screen by lighting up the display.
It’s perfect for those group chats that pop off with 400 messages about a fantasy football trade while you're trying to have dinner with your family. You see them when you're ready, not when the phone demands it.
Your Actionable Security Checklist
Don't just read this and leave your phone wide open. Take five minutes to harden your device right now.
- Audit your "Show Previews": Set it to "When Unlocked" immediately. This is the single biggest win for privacy.
- Kill the "Wake on Lift": Turn off "Raise to Wake." It prevents your phone from turning on the screen every time it moves in your pocket or on a table, which also saves battery life.
- Nuke Sensitive Apps: Go to your banking, 2FA (like Authy or Google Authenticator), and healthcare apps. Manually set their notifications to "Hidden" on the lock screen, even if your global settings are more open.
- Disable Lock Screen Control Center: On iPhone, disable "Control Center" and "Accessories" when locked. This prevents a thief from putting your phone in Airplane Mode immediately after stealing it, which would kill your ability to use "Find My."
- Clean up your Widgets: If you have a calendar widget on your lock screen, realize that it often shows your next meeting location and time to anyone who taps the screen. If you're a private person, get rid of it.
Your phone is a window into your entire life. Stop leaving the curtains wide open for the whole world to look through. Control how you display notifications on lock screen and take back your focus. It's one of the few things in the digital world you actually have power over. Use it.
