Hi, my wife's Nexus 7 goes to a black screen for about 10 seconds then goes to the main screen. The second time she goes into the app it works. It does this with several apps. AVG says it's malware, Device Provisioner, and wants her to uninstall it but it won't uninstall. She also tried Avast which doen not detect a problem. Does anyone know anything about this? Thanks, Lan
