I have a Samsung Galaxy S2 that had a virus, so I reset it to factory settings. Before I did this, I saved my photos to the Cloud, and my apps and contacts to my sd card. I removed my sd card before I reset it. Once I got the phone going again, I put the sd card back in. I don't know how to get my contacts or apps from my sd card installed back onto my phone! Does anybody know how to do this?
