What to Do if You Accidentally Delete Photos From Your Phone

On iOS, this one’s easy. If you delete a photo (or all of your photos ever), they’re not gone for good the moment you tap the trash can icon. Scroll down through your albums in Photos. The very last one you should see—in the main “Albums” listing, not the secondary “My Albums” listing—is an album called Recently Deleted. You can’t miss it. Its icon is boring, gray, and trash-can-shaped.

Tap that, and you’ll be able to restore anything you accidentally deleted. Your iPhone will keep deleted photos around for just around a month or so. the dates listed on the photos are countdowns. Once they reach zero, the photos are automatically exiled from your device forever.
The same is true for any photos you delete on iCloud. They aren’t gone forever—at least, not initially. Just go restore them from the Recently Deleted folder. Ta-da.
Android users have a similar deal. First off, there’s no reason why you shouldn’t be automatically backing up all of your photos to Google Photos. If it isn’t already installed on your Android device, find it, install it, and set it to automatically Back Up & Sync your device’s photos with Google’s cloud.
With Google Photos having your back, restoring deleted images is easy. If you ever accidentally wipe something off your phone (via Google Photos), you have an easy way to restore it. Just pull up Google’s Photos app, tap on the hamburger icon, tap on Trash, tap on “Restore,” and select any photos you want to raise from the dead. If you delete an image in another photos app, just go to Google Photos, find the picture, and download it to your device.
If you’ve deleted your photos before doing setting up Google Photos, Reddit user td888 recommends the free Android app DiskDigger photo recovery, which appears to have worked to solve fire_arms’ initial problem. Install this as soon as you realize your accidental deletion. The app scans through your device’s cache and thumbnails for recently deleted photos and, if it finds what you just removed, it’ll give you the option to restore your pictures. You might not be as thrilled with the results, as DiskDigger notes, but it’s better than nothing:
