PAY ATTENTION: Don’t add any new files to your phone’s memory card, you still can recover deleted photos successfully.
Choose a right Recovery software to recover deleted photos from Samsung galaxy s3. The software I choose is Stellar Phoenix Photo Recovery. This one can recover lost, deleted or formatted music, video files and other multimedia files from digital camera, external hard drives, laptops and desktop, USB Drives, and memory cards.
After install the Photo Recovery, connect your galaxy s3 with computer, launch the photo recovery software, and click on the Recover Photo, Audio, & Video button.
In the “Select Media for Recovery” window, you will notice that the SD card and the internal storage are allocated with a drive letter. If not so, make the setting in Samsung Galaxy S3: Settings -> Wireless & Wifi -> USB Tools -> Connect USB mass storage to PC, and then plug Samsung Galaxy device into the PC.
Select drive and click “start scan” at right bottom. Scanning process may take a while if the library is stacked with files, photos or videos. After the scanning, the software lists the deleted files by file type and file extension, check out the recovered photos in the preview window.
Finally, Locate the photos you’d like to recover, and click “Recover” button to save the recovered files to a specified destination. And then what you need to do is just wait for a while to get the files you want them back.
