DiskDigger is an app to recover pictures on your Android phone that you thought were long gone. If you accidentally deleted a photo, or lost them when uninstalling an app, you can recover them and save them again to your device’s memory.
Using DiskDigger is very simple: you have to select the partition on your Android from which you want to try to recover photos and press the ‘scan’ button. This process can take from a couple of seconds to several minutes, depending on the size of the partition. As it runs, you can see the pictures the app finds.
