i have the Samsung Galaxy s3 (sprint service) my phone was recently updated about a week ago. ever since the update i have had 3 download notifications in my status bar. all of them are Jpeg files, and wont go away. ive tried the obvious swiping them a way, only a temporary solution, they re-appear in less than 10 minutes. ive restarted my phone. and even tried opening the files to try and delete them, but when i click the jpeg, it doesn't open and say"unable to find item" please help.
