I have a WP8.1 mobile phone (see the picture). It happens many times that, after receiving a call, I have to phone back and by mistake instead of touching the right number I press the one above or beneath and suddenly, without a confirmation question, the number is dialed immediately. Even if I end the call in 1-2 seconds it happened that I was phoned back by people I called by mistake. How can I prevent this unpleasant thing. I know that a confirmation message appears if I press that circle with a man inside on the right of the number but the problem is that I can hit the number instead. I would like to also get a confirmation message even if I press the number. How can I do it?
