Hi there! I'm a software developer with a passion for mobile photography and photo editing. I've spent countless hours exploring the ins and outs of photo organization on iPhones, and I'm happy to share my knowledge with you.

Let's talk about unmerging people in your iPhone photos. The truth is, **there's no direct "unmerge" button for people albums on iOS**. Apple's facial recognition technology, while impressive, doesn't yet offer a way to undo a merge decision completely.

Here's why this is tricky and what options you have:

The Complexity of Facial Recognition: Apple's algorithm analyzes faces in your photos and groups them into albums based on recognized similarities. When you merge two people, you're essentially telling the algorithm, "These two sets of faces belong to the same individual." Undoing this merge would require the algorithm to "forget" the connection you established, which isn't currently possible.

What You *Can* Do:


1. Confirm If It's Truly Merged: Sometimes, similar-looking people might be grouped together but not officially merged. Open the Photos app > Albums > scroll down to People. Tap on the album of the merged person. If you see an option at the top to Select, tap it and carefully examine if all the photos indeed belong to one person. If not, you can manually remove individual photos from the album by tapping the trash icon.


2. Remove Misidentified Photos: If you only need to correct a few misidentified photos, this is the most effective method.
* Open the Photos app > Albums > scroll to People > select the merged person's album.
* Tap Select, then tap the photos that are incorrectly assigned.
* Tap the Share icon (square with an arrow) at the bottom left.
* Scroll down and choose Remove from Album.


3. Improve Facial Recognition Accuracy: You can help Apple's algorithm learn and improve its accuracy by:
* Naming People: Go to the People album, tap on a face, and then tap "Add Name." The more names you assign, the better the algorithm becomes at distinguishing individuals.
* Confirming Additional Photos: When you see the "Is this [person's name]?" prompt, take a moment to confirm or deny. This active feedback helps refine the facial recognition model.

A Note About Third-Party Apps: While some third-party apps claim to offer facial recognition and organization features, proceed with caution. Always research apps thoroughly before granting them access to your photo library.

Remember, managing photos and facial recognition is an ongoing process. By actively engaging with your photo library, you can help your iPhone better understand and organize your images.

Tap on the existing (mixed) person. Tap Select at the upper-right, then tap on each photo that is not the person whose name is at the top of the screen. Tap on the Share icon at the lower-left, then tap "Not this person" on the bottom row of options. You may need to scroll to see it.read more >>
