Ask DN: What's up with the letters in the dial pad?

over 6 years ago from , Front-end Developer

Last when I wanted to make a phone call I noticed the letters in the keypad, at the number 2 you have: ABC and then 3, DEF etc etc.

But I realised I have never used them.. Well I used to on my Nokia 3310. But why are they still there? Has anyone used them on his smartphone , if so, where?

I'm curious about your guys stories!
