Google Photos has a ton of awesome ways to edit your pictures. However, when you make a change, the app makes you save a copy to preserve the original. Now, Photos can make changes and preserve the original without clogging up your albums. As Android Police discovered in the latest teardown, when you make a change to a picture in the newest version of the Photos app, it will save the new copy in the same place with the changes applied. However, if you open it later, you can undo the edits you've made to restore the original. This still gives you the flexibility to edit an image without fear you'll destroy it, while also keeping your albums clean of the many duplicates that you can quickly collect by editing a bunch of photos.
