Your gallery shows every screenshot, receipt, and private photo to anyone who picks up your phone. Here is how to lock the sensitive ones away with tools Android already gives you, no sketchy vault app required.
Quick answer
For most people, Google Photos Locked Folder is enough. Open Google Photos, tap Library, then Utilities, then Locked Folder, set it up behind your fingerprint or PIN, and move private photos in. On a Samsung Galaxy, Secure Folder does the same job and isolates apps too. If you also need those photos backed up off the phone, use Ente, an open-source service that encrypts on the device before anything leaves it. Skip third-party vault apps. The built-in tools are stronger.
Hiding photos on Android used to mean trusting a random vault app from the Play Store. That era is over. Google Photos and Samsung both ship a real locked space now, and there is a credible encrypted-backup option when you need one. This guide covers what each tool actually protects you from, how to set it up, and the mistakes that quietly undo the whole thing.
Best option for most people
If you just want private photos to stop showing up when a friend scrolls your gallery, use Google Photos Locked Folder. It is free, it is built in, and it sits behind the same biometric lock as your phone. Nothing else is needed for everyday privacy.
Two cases change the answer. On a Samsung Galaxy, Secure Folder is worth the extra setup because it hides apps and accounts, not only photos. And if you need a private photo to survive a lost or broken phone, you need real encrypted backup, which means Ente. Most readers will use Locked Folder alone. The table below shows where each tool fits.
| Your situation | Use this | Why |
|---|---|---|
| Keep photos out of the gallery on any Android phone | Google Photos Locked Folder | Free, built in, biometric lock, no account beyond Google. |
| Samsung Galaxy, want apps and accounts hidden too | Samsung Secure Folder | A full sandbox backed by Samsung Knox, not just a photo box. |
| Need private photos backed up off the device | Ente | Open source, encrypted on the phone before upload, free tier available. |
| Sharing one sensitive photo with someone | Signal | End-to-end encrypted, with disappearing messages for anything sensitive. |
| Your phone has no built-in locked space | A vetted vault app, as a last resort | Check permissions closely. Built-in tools are the safer default. |
Before you start
Every tool here leans on your device lock. If your phone unlocks with a weak pattern or no PIN at all, set a 6-digit PIN and turn on fingerprint unlock first. Menu wording shifts slightly between Android versions and skins like One UI or HyperOS, so if a label looks different, the option is usually one tap away under the same screen.
Why hiding photos is worth the five minutes

The risk is rarely a hacker. It is ordinary. You hand your phone to someone to show one photo, and they swipe one frame too far. A repair tech has your device for an afternoon. A partner, a sibling, or a curious kid picks it up while it is unlocked on the table.
A locked space turns that exposure off. Photos in Locked Folder or Secure Folder do not appear in the gallery, in search, in Memories, or in shared albums. They sit in storage tied to the phone’s trusted execution environment, the isolated hardware that also guards your fingerprint data, and they need a separate unlock every time. The point is not paranoia. It is putting one wall between a casual swipe and the photos that are nobody else’s business.
Google Photos Locked Folder

Locked Folder lives inside Google Photos. It stores selected photos and videos behind your device fingerprint or PIN, in a space the rest of the app cannot see. This is the right tool for almost everyone, because almost everyone already has Google Photos installed.
To set it up, open Google Photos, tap Library, then Utilities, then Locked Folder. Authenticate with your biometric or PIN, then move photos in from any album. They drop out of the main grid, search, and shared albums straight away. It runs on Pixel phones, recent Samsung Galaxy models, and most current Android phones.
One detail matters more than any other. By default, Locked Folder content stays on the device and is not copied to the Google Photos cloud. Google does offer an opt-in backup that syncs the Locked Folder across your devices, but it is off until you switch it on. Leave it off if you want those photos to exist only on the phone in your hand. Turn it on only if you accept that a copy then lives in your Google account, protected by your account security rather than by the device alone.
Samsung Secure Folder

Secure Folder, available on Galaxy phones, goes further than Locked Folder. Instead of a photo box, it creates an entire sandboxed environment: a separate gallery, separate apps, even separate accounts, all gated behind a biometric or PIN. It is built on Samsung Knox, the company’s hardware-rooted security layer.
To set it up, open Settings and search for Secure Folder, then tap to enable it and choose a lock method. Move photos and videos in through the share menu, or by long-pressing files in the gallery and choosing Move to Secure Folder. The folder gets its own home-screen icon, and you can hide that icon from the app drawer entirely. Android Police walks through the deeper options in its guide to Samsung Secure Folder.
Choose Secure Folder over Locked Folder when you want more than photos isolated: a second messaging app, a separate set of accounts, or files you want walled off from the rest of the phone. For photos alone, Locked Folder is simpler and does the job.
Ente: encrypted backup you can verify

Locked Folder and Secure Folder protect photos on the device. Neither solves the other problem: what happens when the phone is lost, stolen, or dropped in a lake. For that you need backup, and backup means a copy leaves your control. Ente is the tool that closes that gap honestly.
Ente is an open-source, end-to-end encrypted photo service. Encryption happens on your phone, with keys only you hold, before anything is uploaded. The Ente servers store ciphertext they cannot read, even with full access to their own infrastructure. Because the Ente source code is public, that claim is one anyone can audit, which is the difference between trust and a marketing line.
The Android app is well built, and the free tier covers 10 GB, enough for a meaningful set of private photos. Paid plans scale up from there. Confirm the current limits and pricing on Ente’s site before you rely on it. Use Ente for the photos you genuinely need backed up, and keep the rest in Locked Folder or Secure Folder. Not everything needs to leave the device.
Sharing a hidden photo without exposing the rest

Hiding a photo is only half the job. The moment you send one, it leaves your protected space and travels through whatever channel you picked. Choose that channel deliberately.
For anything sensitive, use Signal. It is end-to-end encrypted by default, and disappearing messages let the photo delete itself on both phones after a set time. WhatsApp encrypts messages in transit, but its standard cloud backup is the weak point: a copy can land in Google Drive in a form that is not end-to-end encrypted unless you have turned that option on. Plain SMS and email offer no meaningful protection at all. Open the locked photo, share that one file through Signal, and the rest of your private photos stay where they are.
Common mistakes that defeat the privacy claim
Most privacy failures are not broken tools. They are small setup mistakes that leave a copy somewhere you forgot about. These are the ones that bite.
| Mistake | Why it matters | Better move |
|---|---|---|
| Hiding the photo but leaving the original in the gallery | Moving a photo to a locked space removes it, but a duplicate or a screenshot can linger in the camera roll. | Check the main gallery after every move, and clear the Recently Deleted album too. |
| Assuming nothing syncs to the cloud | The regular Google Photos backup can hold copies that stay online after you delete the local file. | Open Google Photos Settings, then Backup, and confirm exactly what is being uploaded. |
| Trusting a third-party vault app blindly | Some store unencrypted thumbnails or weaken at the cloud-backup stage, the exact moment that matters. | Use Locked Folder or Secure Folder. If you must use a vault app, scrutinise its permissions first. |
| Storing the Ente recovery key on the same phone | If that phone is lost, the photos and the only key to them are gone together. | Save the recovery key in a password manager or on paper, somewhere other than the device. |
| Forgetting that other gallery apps re-index folders | A second gallery app can scan hidden directories and surface thumbnails in its own cache. | Stick to one gallery app, and prefer the built-in locked space over a hidden folder. |
Hide your photos, step by step
Here is the full setup in order. Steps one through four cover everyday privacy. Steps five and six add encrypted backup, and you only need them if a photo must survive losing the phone.
Lock down the device first
Set a 6-digit PIN at minimum and turn on fingerprint unlock. Locked Folder, Secure Folder, and Ente all depend on this lock. A weak screen lock undoes everything below it.
Open your locked space
On most phones, open Google Photos, tap Library, then Utilities, then Locked Folder. On a Galaxy, open Settings, search Secure Folder, and enable it. Choose your lock method when prompted.
Move the sensitive photos in
Long-press a photo or video in the gallery and choose Move to Locked Folder or Move to Secure Folder. Confirm it has left the main grid afterwards.
Check what is syncing to the cloud
Open Google Photos Settings, then Backup, and confirm the regular backup is not holding copies you meant to keep local. Do the same for Samsung Cloud if you use a Galaxy.
Add Ente for off-device backup
Only if you need it. Install Ente, create an account, and sync just the photos you want backed up. Encryption is on by default, so the upload is protected from the start.
Store the recovery key off the phone
Ente shows a recovery key during setup. Save it in a password manager or write it down and keep it somewhere safe. Without it, a lost phone means lost photos.
That sequence covers every threat model in this guide, from a friend’s curious swipe to a phone that never comes back. The next callout is the one warning worth reading twice before you finish.
Safety first
Locked spaces and encrypted services have no password recovery by design. That is the feature, not a flaw: it is what keeps an attacker out. But it cuts both ways. Forget your PIN, or lose your Ente recovery key, and the contents are gone for good, with no support line that can restore them. Pick a PIN you will not forget, and keep recovery keys somewhere other than the phone they protect.
The verdict
The verdict
Bottom line: for everyday privacy, Google Photos Locked Folder is all most people need, and it takes about two minutes to set up.
Samsung Galaxy owners who want apps and accounts hidden, not just photos, should use Secure Folder instead. Add Ente only when a photo genuinely must survive a lost or broken phone, and store its recovery key off the device. Skip third-party vault apps: the built-in tools are stronger and free, and a vault app is most likely to fail at the cloud-backup stage, the exact moment you were counting on it. Match the tool to what you are actually protecting against, and five minutes of setup buys you a real wall.
Questions people actually ask
- Does Google Photos Locked Folder sync to the cloud?
Not by default. Locked Folder content stays on the device unless you opt in. Google offers an optional backup that syncs the Locked Folder across your devices, but it is off until you switch it on. If you want a private photo to exist only on the phone, leave that backup off. - Can someone with my phone access my hidden photos?
Not without your biometric or PIN. Locked Folder and Secure Folder gate every entry behind the device lock, and the contents sit in protected storage. Forensic recovery is possible in theory, but it takes a determined attacker with physical possession and specialist tools, not a casual snoop. - Is Samsung Secure Folder safer than Google Photos Locked Folder?
For photos alone, both are strong enough. Secure Folder does more: it sandboxes apps and accounts as well, behind Samsung Knox. Choose Secure Folder if you want broader isolation, and Locked Folder if you just want private photos out of the gallery. - How do I share a hidden photo without exposing the rest?
Open the locked space, select just the one photo, and share it through an encrypted channel like Signal. Only that file leaves your protected space. Everything else stays locked. Avoid plain SMS or email for anything sensitive. - Is hiding photos on Android the same as encrypting them?
Locked Folder and Secure Folder use the device’s hardware-backed encryption, so on the phone the two overlap. The gap is the cloud. Anything you back up is only truly encrypted end to end if the service does it, which is why Ente matters for off-device copies. - What happens if I forget my PIN or lose my recovery key?
You lose access to the contents, permanently. Locked spaces and encrypted services have no password reset by design. Choose a PIN you will remember, and keep any recovery key somewhere safe and separate from the device it protects.
How we tested
We worked through Google Photos Locked Folder, Samsung Secure Folder, and Ente on current Android builds, using a Google Pixel 8a running stock Android and a Samsung Galaxy S24 running One UI. Each step was checked on the device, cross-referenced against vendor documentation, and we revisit this guide whenever the apps change behaviour.
