Great phone unless ...

pressing the emergency button repeatedly.
When my mother 86jährigen it's a few times happened that she has accidentally while handling the phone pressed the red button on the back. When this fact for more than 2sec. holds bridged, an emergency call goes to previously stored numbers out. But since I have stored only home phone number it was not so bad.
You get in the case an SMS with the text: please call back emergency.
So please think before how well one with the phone clearly comes before saving real emergency number such as 112 or similar.
