I have so many questions but I will take it one at a time. I love the phone but I get frustrated because I can't change some of the default settings. #1. How can I extend the ringing time on the phone before it goes to the voice mail? #2. When I am talking on the phone the screen locks itself so if I need to punch in numbers to order something, I have to keep unlocking the screen first. I found the feature that stops it from locking when the phone is idle but it doesn't affect the screen locking when I am on the phone. Thanks
