I've used some PC tools for SD card file recovery before, but perhaps if I had Hexamob Recovery, I could have used it instead. I haven't tested this app, but it currently has a bunch of 5-star reviews. Requires root! Have you deleted your data? Don't worry! Hexamob Recovery PRO will recover it! - Recover and recycle easily deleted files from the external sdcard and/or internal storage device (smartphones). Tablet version is coming soon!
