Short answer
The fastest way to hide photos on Android without an app is Google Photos' Locked Folder: open Google Photos, tap Collections, then Locked, set it up, and move photos in from a photo's three-dot menu. It keeps them out of the grid, search, Memories and other apps, and nothing leaves the phone unless you turn on its backup. On a Samsung, Secure Folder does the same with hardware isolation. Both open with your screen lock, so they protect against a stranger, not against anyone who knows your PIN. For that you need a vault with its own code.

Seven ways to hide photos on Android, with the taps
From the weakest to the strongest. Each entry says what it hides from, what unlocks it, and whether it survives a new phone, because those three things are the whole difference.
- A dot in the folder name, or a .nomedia file
In a file manager, rename the folder to start with a dot, or drop an empty file called .nomedia into it. The gallery stops scanning it. Any file manager shows it again with one toggle, and nothing is locked or encrypted. This is tidying, not hiding.
- Hide albums in Samsung Gallery
Gallery, menu, Settings, Hide albums, and switch an album off. It vanishes from the Gallery's album view and nothing else; the same settings page lists it for anyone who looks. No lock. Same tidying, on a Samsung.
- Google Photos Locked Folder
Google Photos, Collections, Locked, Set up. Then on any photo: three dots, Move to Locked Folder. Items leave the grid, search, Memories and albums, other apps cannot reach them, and nothing is backed up unless you switch that on. It opens with your screen lock and cannot have a different one. Android 6 and later.
- Files by Google Safe folder
Files by Google, Safe folder, set a PIN or pattern. Files inside are stored with Android's storage encryption and hidden from search and other apps. For documents and PDFs this is the built-in answer. Forget the PIN and Google says you cannot get the files back; there is no Drive backup for it. Android 8 and later.
- Samsung Private Album
One UI 8.5 adds a Private Album inside the Samsung Gallery, a locked album in the main profile, closest in spirit to Locked Folder. If your Gallery does not show it, your phone has not had the update.
- Private Space or Secure Folder
Android 15 and later: Settings, Security and privacy, Private space. Samsung: Settings, Security and privacy, Secure Folder. Both create a second profile with its own apps and its own lock, hidden from the main one. Private Space needs a Google account and cannot be migrated to a new phone; Secure Folder needs a Samsung account and moves only Samsung to Samsung over a cable. Both are strong; both are visibly present on the phone.
- AlterVault
Install, set a code, add photos. Every file is encrypted individually with XChaCha20-Poly1305 behind a code your screen lock does not open, one shake swaps the vault for an ordinary gallery, and the backup is one encrypted file that restores on any phone. No account. Free up to 10 items, $24.99 once after that.

Ranked by who they actually stop
- Someone scrolling your gallery
- All seven stop this. If this is the whole problem, use method 3 and stop reading.
- A stranger holding your unlocked phone
- Methods 3 to 7 stop this. The dot trick and the Samsung album hide fall to any file manager or to the Gallery's own settings page.
- Someone who knows your PIN or pattern
- Only method 7, and method 6 if you gave the second profile a different lock from the phone's. Locked Folder, Safe folder's device fallback, Private Album and a Secure Folder sharing the phone's lock all open for anyone who has watched you unlock.
- Someone who takes the phone, or the storage, apart
- Methods 6 and 7. A Knox container and per-file encryption keyed from a code are the two designs that leave nothing readable. Everything else relies on the phone's own encryption and the lock in front of it.
- Someone who asks you to open it
- Only method 7. Every other option gives you refuse or comply. A decoy gallery is a third answer, and it is the reason vault apps exist as a category.
On a Samsung
Samsung phones have the most built-in options and the most confusion. Hide albums only tidies the Gallery. Private Album, on One UI 8.5, locks photos inside the Gallery behind biometrics and is the quick choice. Secure Folder is a whole second profile in a Knox container, the strongest thing on any Android phone, with a Samsung account attached and no way off Samsung hardware.
The cleanup matters more here than anywhere. Samsung Gallery can sync to OneDrive, and a photo you hide locally may already be in that cloud. Check Gallery, menu, Settings, Sync with OneDrive before you assume a hidden photo is only on the phone.

On a Pixel
Locked Folder is the native answer, and on a Pixel 4 or later the camera can save straight into it: long-press the preview thumbnail and choose Locked Folder, so a sensitive shot never enters the main library. Private Space, from Android 15, is the place for whole apps; screenshots taken inside it stay inside it.
The Pixel trap is backup. Google Photos backup is on for most Pixel owners from the first day, so any photo you hide today was uploaded the day you took it. Locked Folder's own backup is off by default and separate; leave it that way unless you would rather have the cloud copy than risk losing the photos with the phone.

Where the first six stop
The first six hide photos from the gallery, and the better ones hide them from other apps too. None of them encrypts your files with a key that only you hold: they sit inside the phone's own encryption, behind the phone's own lock or a second profile's lock.
Five of the six open with the PIN the person next to you has already watched you type. The sixth can have its own lock, but announces itself with an icon, a Settings entry and a notification. None has anything to show someone who asks.
AlterVault, the one that holds up
It protects the files rather than the folder, behind a code your phone does not know, and it gives you something to hand over.
- A code your screen lock will not open
- Every file is sealed with XChaCha20-Poly1305 before it is written, thumbnails included. The key comes from a code you choose, through Argon2id, wrapping a master key in the Android Keystore. Forget the code and a 12-word phrase you wrote down gets you in; nothing else does.
- Something to hand over
- Shake once and the vault becomes an ordinary gallery with ordinary photos in it. Shake again for a code pad that nobody else can fill. Being asked has an answer.
- Documents too
- PDFs and scans go in through the system picker, into the same encrypted store, behind the same code. No separate Safe folder with a separate PIN to forget.
- Moves with you
- One encrypted backup file restores on any Android Android 8.0 or later, and on an iPhone. No account, nothing on a server, no brand requirement. Free up to 10 items with every feature on.
AlterVault runs in the ordinary app sandbox, not a Knox container, and its Android build holds the INTERNET permission for the purchase check through RevenueCat and for anonymous usage events sent to PostHog. Photos, file names and your code never touch the network. Against a live attacker on the device with your code, Secure Folder's hardware isolation is the stronger design; against everyone who does not have your code, per-file encryption is what makes the files, and the backup, unreadable.
The cleanup that decides whether any of it worked
Hiding one copy does nothing if three others sit somewhere you forgot. Do these four before trusting any method above.
- Check Google Photos backup
If backup was on when the photo was taken, it is on Google's servers and visible at photos.google.com from any browser. Hiding or deleting the local file changes nothing there. Delete it in Google Photos as well, which removes it everywhere.
- Empty the Trash
Deleted photos stay fully viewable in Google Photos' Trash for 60 days, in Samsung Gallery's Recycle bin for 30, and in the Files app's Trash for 30. Empty each one you use.
- Check the other clouds and the other apps
Samsung Gallery sync to OneDrive, Amazon Photos, Dropbox camera upload. Then WhatsApp, Telegram and Instagram, which keep their own copies in their own folders and often their own media backups.
- Check the other devices
A tablet or laptop signed in to the same Google account has the same Google Photos library. A photo hidden on the phone is still in the grid there until it is deleted from the cloud.
Questions
What is the best way to hide photos on Android?
For photos you simply do not want to scroll past in front of someone, Google Photos' Locked Folder: free, built in, hidden from the grid, search and other apps. For photos that must survive someone who knows your PIN, an encrypted vault with its own code. AlterVault seals each file behind a code your screen lock does not open, and one shake swaps the whole library for an ordinary gallery.
How do I hide photos on Android without an app?
Google Photos, Collections, Locked, Set up Locked Folder, then move photos in from a photo's three-dot menu. It keeps them on the device and away from other apps, and nothing is backed up unless you turn that on. It opens with your screen lock, so it protects against a stranger, not against anyone who knows your PIN.
How do I hide photos on a Samsung phone?
Three ways. Gallery, Settings, Hide albums only unlists an album. Private Album, in One UI 8.5, locks photos inside the Gallery behind biometrics. Secure Folder, under Settings, Security and privacy, moves them into a Knox container with its own lock, tied to a Samsung account. For a code your screen lock does not open and a backup that moves off Samsung, use a vault app.
How do I hide photos on a Pixel?
Google Photos' Locked Folder, which on a Pixel 4 or later the camera can save into directly. Private Space, from Android 15, hides whole apps behind a separate lock. Remember that Google Photos backup is usually on from day one, so delete the cloud copy of anything you hide.
How do I find hidden photos on Android?
Depends how they were hidden. Dot folders: turn on Show hidden files in a file manager. Samsung albums: Gallery, Settings, Hide albums. Locked Folder: Google Photos, Collections, Locked. Safe folder: Files by Google, Safe folder, with the PIN. Secure Folder: the quick panel tile or Settings, Secure Folder.
Does a .nomedia file actually hide photos?
Only from the gallery app. Any file manager shows the folder again with one toggle, and nothing is locked or encrypted. It is useful for keeping sticker caches out of your gallery, not for privacy.
If I hide a photo, is it still in Google Photos?
If backup was on when the photo was taken, yes. The copy on Google's servers is unaffected by anything you do to the local file, and it shows in the grid on every other device signed in to your account. Delete it from Google Photos as well, then empty Trash, which keeps it for 60 days.
Is Private Space better than Secure Folder?
They are the same idea, a second locked profile, from Google and Samsung. Private Space runs on any Android 15 phone and needs a Google account; Secure Folder runs on Samsung phones in a Knox container and needs a Samsung account. Neither migrates to a new phone on its own and both are visibly present. For hiding apps, pick whichever your phone has. For photos with consequences, see method 7.
