My verizon 9530 is making calls on its own and they don't show up on my call log I have gotten 5 phone calls today from a couple friends asking me if I just called them and I've seen it on one of their phones when I was with him earlier. Has anyone ever heard of anything like this I'm going in tomorrow to get a replacement I think.
This happened to me when I had the S1 - it was caused by inadvertent screen pushes (putting the phone in my pocket or holster before it timed out or not locking it) If this is happening when the phone is out - like on a desk or something, you may have other issues. Hope this helps you
