My father just picked up a Casio G'zOne Commander from our local Verizon store today and it's been an uphill battle teaching him how to use his new toy thus far. He's not very tech savy but I've managed to teach him how to accept and place calls & texts and even take pictures. Trouble is the touch screen itself, in particular when he's on the phone with someone. For some reason I think he's tripping the end button on the screen with his face and occasionally hangs up on people on accident. This is his first touch screen phone and he's already growing frustrated with it and missing his old phone. Is there any settings I can tweak to make it easier for him and to stop him from hanging up on people by accident? Thanks in advance and this forum looks like a great resource.
