iPhone 5 Randomly Calling People
Can someone please help me out with this issue.
My iPhone has recently started calling people on its own. I would leave it to charge on my table and without any interference it would randomly call people that are on my contacts list and people that aren't even on my contacts. This is a huge concern on my part because I just have 50 minutes on my line and just last week it's already used up 30 minutes of talk time because of this glitch. I restored my phone thinking that would hopefully fix it and sadly the problem still exists. I have Voice Dial off and have also tried keeping Siri off as well. After my phone started calling people again I enabled Siri again just because I don't think it was causing this issue. It calls people while the phone is locked and a lot of these calls range from 7-11 minutes and some are much shorter ranging from 1-15 seconds.
iPhone 5 is on the latest firm ware with the latest carrier update as well. CAN SOMEONE PLEASE HELP ME ?
iPhone 5, iOS 8.3
