Hi, my wife and I both have Iphone 5s phones that we have owned since December of last year. I love my phone, and for the most part, she does too. However, one thing is driving her nuts. When she receives a phone call, she must drag the button on her screen from left to right to answer the call. For some reason, the screen doesn't recognize her touch when she attempts to do so, and she gets frustrated and winds up losing the call. I wish there was some way that we could set her phone so that she could simply hit one of the manual buttons, such as a volume key, or maybe tap her screen twice to answer the call. Maybe this is covered in the online manual, but I can't find it. Any suggestions you could give me would be greatly appreciated. I would like to see her love the phone as much as I do. Thanks!
