I'm happy to announce that DiskDigger for Android now supports recovering HEIF images (High Efficiency Image Format), as well as HEVC videos. The upcoming release of Android P is planned to support saving photos from the camera using the new HEIF format, and DiskDigger is now ready to recover them in case they are accidentally deleted.
DiskDigger for Windows, on the other hand, has already been able to recover HEIF images for a while now. If your Android device uses a microSD card for storing photos or videos, it's recommended to remove the card and connect it to your PC using a card reader, and scan it using the Windows version of DiskDigger.
