So that the question is this, when I receive a call sometimes I get the screen with an icon Talk to drag to the right only and others, I get two icons hook one for green and one red next to hang up, someone would know why this happens and tell me what is the reason? Besides I have made some contacts picture to come out when they call me and I do not miss either large or small, I have the last upgrade which is 7.1. Thanks and regards
