Welcome Matt. So sorry this has happened to you. I agree with everyone's advice not to use any divination divice. You can talk to your Uncle in prayer or meditation. I believe they hear us if we think of them. They also come to us in our dreams. Try a dream journal to help recall your dreams. Good luck with this situation
 
Hi Matt. I also agree with everyone else. There are just too many malevolent spirits out there who are just looking for an invitation to come into your life. You can pray to the angels to teleport your uncle into your life or into your dreams. This would be a much safer approach. Here's, wishing you the best.
 
Uninstall it. Then download wickr or anything with a forensic swiping feature.
When you delete things, the data still exists until new files overwrite it. Forensic swiping programs like wickr me will scrub all traces of the app from the phone. If ur talking paranormal stuff, the dormant data alone can be dangerous.
