How can I undelete images from my phone?

Episode 1266 (26:31)

Mark from Ohio

Mark accidentally deleted photos from his Android phone. How can he get it back? Leo says he can do it by mounting his Android device to his computer and put it in MTP mode. Then he can use an undelete utility to restore the image. There may also be an app in the Google Play store that can do it. Mark should turn off the phone and do nothing with it until he's ready to restore it. Connect it to his computer and use apps like Install Image or Disk Digger.

Mark also uses Facebook, but he doesn't use the app. How can he get rid of the app? Leo says he can't. Android made a deal with Facebook to have it on the phone. If he's worried about someone stealing his data, it's encrypted via https secure browsing. So it's scrambled.
