I got my S3 the Saturday after Thanksgiving and I have not had any problems with it until after I received the JB update. Of course maybe it isn't a problem. I have noticed that the app Backup Assistant Plus is not listed in the apps. It is listed in the Settings menu under the Accounts listing but if I press it it I get I get a black screen and then a pop-up message saying "Unfortunately, Settings has stopped" with a selection of "OK" under it. It is also listed as Backup if you pull up your contacts and then select the Menu button, but this seems to do nothing. No error message or anything. I tried to pull up my contacts online and the list is empty. So where are my contacts being backed up now?
