This is a weird one happening on my Dad's phone. He and I both have S3s and his will not correctly call numbers back on his missed calls. I have checked and only on his missed calls the phone for whatever reason is not affixing a number '1' before the area codes. This causes the phone to dial the numbers as international numbers on the callback. He can still dial normally from his address book and and can even call back numbers in his recent listing that weren't missed just fine. The issue is solely with those calls that were missed. Here is a screenshot: I have scoured the web for hours and cannot find anyone else who had this problem. What could be causing it?
