I'm using Nexus 4. I have hidden many images in Keepsafe, but now I want them to unhide and I can't. No arrow button states for unhiding pics. Can you help me?
You need to follow the official instructions for unhiding a picture in KeepSafe. Use the link posted below to reach the page with instructions. I wouldn't advise reinstalling the application, because it might be possible to lose everything that you previously hid.

Contact the developers, and they should provide other hidden ways to unlock the pictures: firstname.lastname@example.org
