I have a problem with my phone calling people by itself and was wondering if anyone else was having this problem. The numbers it calls are not on my contact list and often the people will phone back asking who I am because "I called them". Its not a pocket dial, my phone is an lg optimus black with a lockscreen and its in my pocket when it happens so there is no way I could have messed with it. The outgoing calls do not appear in my call log. What is going on? Any ideas?
