I updated my s3 to Jelly Bean last week, and on random occasions I have received an exclamation mark inside a triangle notification on the notification bar, when I bring down the notification panel it warns me about data roaming. When I press the notification it takes me to the mobile networks menu. I do have data roaming disabled, so this warning seems strange. Its only started happening since the update (which may be just a coincidence) I wondered if anybody else has experienced similar and any ideas what could be causing it? My S3 is not rooted.
