Google Photos for Android is updated to add new Archive feature to remove the clutter0
The Archive page, where the tagged photos are sent to hang out in exile, is where users will go to un-Archive any photo. You'll find the Archive feature in version 2.15 of Google Photos for Android. Over the next few days, the update should extend to both the iOS and web versions of the app.
The Archive feature can be accessed for any picture on Google Photo by tapping on the three dot overflow menu. The first time that you use it, a tutorial will run that will give you directions on how the feature works.
You can check out screenshots showing the Archive feature by clicking on the slideshow below.
