On most Android phones, open Files by Google, tap Clean, then the Duplicate files card, and move the copies to Trash. On a Samsung, open Gallery, tap the menu, then Clean out and Delete duplicate pictures. Neither groups bursts, edits or chat re-saves, so those need a look of their own. Empty the bin to get the space back.

How do I delete duplicate photos on Android?

Use Files by Google, Google’s own file manager. Its Clean tab finds duplicate files on the phone.

1. Open Files by Google and go to Clean.
2. Find the Duplicate files card and tap Select files.
3. Check the selection, then tap Move [number] files to Trash.

In each set, Google’s help page says the original file is marked with an Original badge. Leave that one and clear the rest.

Nothing is gone yet. Files by Google keeps what you move to Trash for 30 days, then deletes it automatically.

How do I delete duplicate photos on a Samsung phone?

Samsung gives you three ways in, and the Gallery one is the quickest.

1. Open Gallery and tap the menu (three lines).
2. Tap Clean out, then Delete duplicate pictures.
3. Tap Delete duplicates.

Samsung’s Gallery guide says this removes the duplicates and keeps the originals. If the option isn’t there, you probably have no duplicates for it to find.

The other two routes list duplicate files of every kind, not just photos:

Route	Path	Who picks the keeper
Gallery	Menu > Clean out > Delete duplicate pictures	Gallery keeps the originals
Device care	Settings > Battery and device care > Storage > Duplicate files	You
My Files	My Files > Analyse storage > Duplicate files	You

On older software, Battery and device care is called just Device care. Take care in My Files. Samsung’s own warning is that if you tick every file in a set, the original goes too.

Does Google Photos delete duplicate photos?

Not as such. Its help pages describe no duplicate finder. What it has is photo stacks: nearly identical photos of the same subject, taken within a short time, grouped under one cover.

To turn them on, open Google Photos, tap More, then Stack similar photos. Stacks only cover backed-up photos, and Google is clear that stacking doesn’t change your available storage. To actually clear one, open the stack, tap the menu on the photo you want and choose Keep this, delete rest.

Before you delete anything in Google Photos, know where it goes. With backup on, deleting a photo removes it from your phone, from your Google Photos backup and from every device signed in with backup turned on. If you only want the space on your phone back, use Free up space on this device from your profile picture instead. That removes the phone’s copies of backed-up photos and leaves your library alone.

Why are there still near-copies after that?

Because the duplicate tools are built for copies of the same file. Most of what fills a camera roll isn’t that.

Kind of near-copy	Example	Built-in help on Android
Exact copy	The same photo saved twice	Files by Google, Samsung Gallery, My Files
Similar shots	Five taps of the shutter at one view	Google Photos stacks (backed-up only), Samsung’s similar image grouping
Burst	Ten frames from one long press	Not grouped by the duplicate tools
Re-saved edit	A crop saved beside its original	None
Chat round trip	Your photo sent back in WhatsApp and saved again, smaller	None

Samsung’s Gallery can group similar-looking pictures on newer phones, but grouping is just how they’re arranged. You still choose and delete each one yourself.

Bursts often start by accident. On a Samsung, Camera settings > Swipe Shutter button to decides whether swiping the shutter takes a burst or makes a GIF. Our guide to why one camera roll ends up with 246 copies of the same photo explains each kind of near-copy and which to keep.

Is there an app that finds similar photos on Android?

Yes, and that’s the job Siftlo was built for. It groups exact duplicates, near-identical shots taken seconds apart and burst sets, and proposes the one to keep in each set. Near-identical shots open side by side, so you can see what you’re giving up before you choose.

You review by group, never file by file. Nothing moves until you confirm. Then Android shows its own confirmation and the photos go to your phone’s bin, where an undo can still bring them back.

Finding and clearing duplicates is free and never capped. It runs on the phone and needs no account. See everything Siftlo does on the device, including large files and old screenshots.

Why hasn’t my storage gone up after deleting duplicates?

Because every route above sends photos to a bin first, and a bin still takes up space. Files by Google, Samsung’s Gallery and Google Photos each keep deleted items for 30 days.

To get the space back now:

1. Files by Google: open Trash from the menu, select what you’re sure about and delete it.
2. Samsung Gallery: tap the menu, then Trash, then More options > Empty > Delete.
3. Google Photos: tap Collections, then Trash, then More > Empty Trash > Delete permanently.

Google’s trash help covers the Photos side. Siftlo says queued to free after a clean for the same reason, and offers to empty the bin when you’re ready, with one more confirmation from Android.

Duplicates are usually one part of a full phone. For apps, WhatsApp and downloads, see how to free up space on Android.

Questions people ask

If I delete a duplicate in Google Photos, is it gone from my backup too?

Yes, if backup is on. Google says deleting a backed-up photo removes both the Google Photos copy and the one on your phone, on every device with backup turned on. To remove only the copy on your phone, open the photo, tap More, then Delete from device.

Does Samsung's Delete duplicates keep the original?

In Gallery, yes. Samsung says it removes the duplicates and saves the originals. In My Files you tick the copies yourself, and Samsung warns that ticking every file in a set deletes the original too, so always leave one.

Will Siftlo delete a photo without asking?

No. Siftlo proposes a keeper for each set and nothing moves until you confirm. Android then shows its own confirmation, and the photos go to your phone's bin, where you can still bring them back.
