Got a Galaxy S7 two weeks ago and took a lot of photos with the phone as it does the job very well. The question for now is that some of the photos got deleted by my young boy. I tried Undeleted and Recuva suggested by others but they seems not help in my case. I am wondering is still possible to restore those photos?
When you delete a photo it is not gone.
The space that the photo takes up simply becomes available for other data. Once that space is used the photo will then be gone.
You can use the free program Recuva to restore the photos if they have not been overwritten.
http://www.piriform.com/recuva Have Recuva scan your SD card or device memory (wherever the photos were saved) for pictures.
If they haven't been overwritten, Recuva gives you the option to restore them.
If Recuva doesn't work for you, I suggest you try Android data recovery to scan your Galaxy s7, maybe it works.
