Feature: T9 Layout

Probably I'm off topic, but I think it's useful adding a button or a tip (during the first boot of phone) that explain how to do to hide the keyboard.

Currently the possibility that the keyboard can be hidden by scrolling down it's not explained clearly.

What do you think?

Status changed to 'Confirmed' because the bug affects multiple users.

Hi!
I duplicated this bug, so I paste my description here to share an idea that blind people use T9 layout to write messages cause they feel the buttons. You could "feel" (touch) the buttons by stickers on the screen so that we were able to write without looking on the phone as we used to do with old mobile phones.
------------
So here is may description from a duplicate:

"I wonder if anyone will support my idea of creating a numerical keyboard option as we used to have in standard phones. What for?

1. Did You know there are blind people who are able to write a message? Did You ever wrote a SMS message while driving a car/running or walking/ under the table on a meeting/at school without looking on the screen? Yes, it was possible. Now as we have smartphones we are forced to look on the screen to tap the right "button".
Now if we had the proper cover for our phones, a simple 10 stickers or a prepaired foil for the screen, we would still be able to write only by touching, without having to look. But there is no proper keyboard layout.

2. I have a Nexus 5 device with Android. While turning on the phone with inserted SIMcard, we have to provide PIN number. Do You know Your PIN number? I didn't. Ubuntu phone forced me to remind it to myself. Why? Android displays the 0-9 numerical keyboard with the alphabet under the numbers, so that I do not have to know that for one of my phones the PIN is 6529 one for another 9274. If I have letters on my keyboard I can keep in mind 4-letter words, not numbers. I'm not an Android developer but I think there is a reason why they display the numerical PIN-keyboard this way."

Is there any progress with this?
