Occasionally when I complete a call and disconnect my phone will randomly dial a recently called number. Last night I disconnected from a call and in a minute or two I began hearing a voice that I thought was coming from outside. I happened to look down at my phone and saw I was connected to another person but before I could answer he hung up and then immediately my phone began dialing another number. I have installed an app called Better Contacts but the random dialing started several weeks after installing the app. The problem also started long before the 2.2 update. Has anyone else experienced a problem like this? If so are you using the standard Phone app or do you have an aftermarket contact app?
