When you’ve worked with Samsung devices as long as I have, tearing them down, tuning their software, troubleshooting what others can’t, you start to notice that it’s the small features that quietly make the biggest difference. One of those underrated tools? The ability to add contact information directly to the lock screen of your Galaxy S25.
Now, I get it, most users don’t even think about this setting until they’ve misplaced their phone or faced a moment where a good Samaritan had no way to return it. But here’s the thing: with the Galaxy S25 and One UI 7, Samsung hasn’t just hidden this feature in a settings submenu, they’ve refined it.
They’ve given us, the technicians, a smoother, smarter interface that actually makes customization worthwhile.
This guide isn’t just a basic walkthrough. It’s a no-nonsense, technician-level deep dive into why you should care about this feature, how to set it up properly, and what to do when things don’t behave the way they should.
If you’re using a Galaxy S25, don’t skip this. Because sometimes, a few lines of text on a lock screen can save you a world of hassle later.
Why Add Contact Information to the Lock Screen?
Let me tell you something I’ve learned after working on Samsung devices for over a decade, fixing broken phones is easy. What’s not so easy is fixing the moment of panic when someone loses their phone and realizes they’ve locked themselves out of the one tool that could’ve helped them get it back.
That’s where lock screen contact info comes in. It’s one of those rare features that costs you nothing to set up but could save you hundreds of dollars, and a whole lot of headache, down the line.
Real Talk: Phones Get Lost, Not Just Broken
I’ve had customers come into my shop with horror stories. Left their phone in a rideshare. Slipped out of a pocket at the gym. Misplaced it in a café five minutes after leaving. You’d be surprised how many good people find lost phones, and you’d be just as surprised how hard it is for them to figure out who the owner is.
Face ID? Doesn’t help. Fingerprint sensor? No good. Passcode lock? Ironclad. So unless you’ve got your name and an alternate contact method right there on the lock screen, that honest person is staring at a $1,000 brick with no way to help you.
Samsung Built This Feature for a Reason
Samsung didn’t throw the “Contact Information” option into the lock screen settings just for show. It’s baked into One UI for a purpose: real-world protection. It’s like a luggage tag for your phone. Only smarter, and digital.
You can type in your name, an alternate phone number, an email address, anything that lets someone reach you without unlocking the device. The info sits quietly at the bottom of the lock screen, visible to anyone who picks it up, but not intrusive or compromising.
Security vs. Accessibility: Striking the Balance
Now, let’s address what some users get wrong. They’re either too cautious, refusing to put anything at all because they think it’s a “privacy risk”, or they’re too casual, putting their full home address or personal ID numbers, which is overkill.
Here’s what I tell my clients: use just enough to help someone help you, but not enough to help someone scam you. A name and a backup number work fine. An email is great too. If you’re using a work number, even better.
Experience Says: Most People Skip This-and Regret It Later
The truth is, 90% of Samsung users I meet don’t bother setting this up. But the 10% who do? They’re the ones who call me relieved, not panicked. They’re the ones who get their phones back within hours, not days, or never.
And from a technician’s point of view, that’s what makes the difference. Preventive features like this separate the casual users from the smart ones.
If you’re using a Galaxy S25, don’t overlook this. You wouldn’t leave your wallet lying around without ID, so don’t do it with your phone. Take 30 seconds, drop your contact info on the lock screen, and give yourself a fighting chance. You’ll thank yourself later, and trust me, I’ve seen plenty who wished they had.
Step-by-Step Guide: How to Add Contact Info to the Lock Screen
I’ve spent years inside Samsung’s interface, flashing firmware, troubleshooting bugs, unlocking features most users never touch. But let’s be honest: not every solution requires a technician’s toolkit. Sometimes, it’s as simple as navigating a few menus and making the right tweaks. That’s the case here.
If you want to add your contact details to the lock screen of your Galaxy S25, follow these exact steps. No fluff, no guesswork, just the clean, technician-approved method that works every time.
Step 1: Head Into the Core – Open Settings
- Start by unlocking your phone (biometrics, PIN, however you’ve secured it).
- Tap the Settings icon from your app drawer or Quick Panel.
- Now pause, this isn’t just any menu dive. You’re about to tweak what the world sees before your phone even unlocks.
Step 2: Go to Lock Screen and AOD Settings
- Inside Settings, scroll until you see Lock Screen and AOD.
- Tap it. This is the command center for anything visual or functional before unlocking.
Step 3: Tap on “Contact Information”
- Look for the option labeled Contact Information.
- Depending on your theme or One UI version, it might be slightly lower on the list, tucked just beneath Roaming Clock or Widgets.
Step 4: Enter Useful, Concise Information
This is where you get one shot to communicate with the world, without unlocking the phone.
Enter your name, alternate phone number, or email.
Keep it concise but helpful. Something like:
- “If found, please call 555-123-4567”
or - “Lost? Contact: email@example.com”
Don’t write an essay. Don’t include personal identifiers like your home address or ID numbers. This isn’t a ransom note, it’s a return label.
Step 5: Save and Test
- Hit Back or tap Done, depending on your interface.
- Now lock your phone.
- Wake the screen and check the bottom or center area (depending on your lock screen layout) your message should be right there, front and center.
Technician’s Insight:
If it doesn’t appear, you may be using a custom lock screen (Good Lock, Theme Store, etc.) that overrides this feature. Either disable those temporarily or reset your lock screen layout from Settings > Home Screen > Restore Default Layout. Transcribe Voice Recordings on Galaxy S25
Final Thoughts
Look, anyone can use a Galaxy S25. But not everyone knows how to use it well.
And this? Adding contact info to your lock screen? It’s one of those small, easily forgotten features that separates casual users from people who actually understand what their phone is capable of.
I’ve been working on Samsung phones since the days of TouchWiz. I’ve seen features come and go, gimmicks that look great on paper but never make it past the first software update. But this one? This one’s stuck around. You know why? Because it’s practical. It works. And when something works, especially in a moment of crisis, like when your $1,200 phone is sitting in a stranger’s hands, those are the moments that remind you why it was worth setting up.
So here’s my last bit of advice, not just as a technician, but as someone who’s seen far too many people show up at my workbench wishing they’d done this sooner:
Set it now, not later.
Keep it simple. Keep it smart.
And never underestimate the power of being prepared.
Your Galaxy S25 is one of the most powerful tools in your pocket. Treat it like it. Use every feature that makes it not just smarter, but safer.
Until the next tune-up,
Keep it locked. Keep it optimized.
