Hi again.
Since I believe such a keyboard layout will help a lot of Persian Users I did some searches on the frequency of letters and I came up with the following chart.

First I need you to take a look at the layout I'm suggesting:

As you see, it's very similar to the Persian Qwerty Keyboard, but some changes are applied and the reason comes as follows:
My idea is to let the areas of letters placed on the Qwerty keyboard remain unchanged, which means if a letter is placed at the top right corner, let it be. What I think would make the keyboard easier to use is to place the letters on a
single button in order of frequency usage, which means on the first press the most frequented letter will be typed and pressing a second time shortly after makes the next frequented letter to be typed and the same thing for the third press. I believe it's not needed to place the buttons exactly on the order of a Qwerty alike keyboard since buttons are merged two-in-one or in case of Persian language even three-in-one. If the user is familiar with a Qwerty keyboard, he knows where the hand should go for a required letter, e.g. top left, bottom right or etc. but since it's a mobile screen and not a real keyboard the user needs to spend some time learning the orders placed on a single button; even if the letters on a single button were put on the exact Qwerty form keyboard, the user would have needed to spend the same time learning it. So the frequency thing is just an idea of mine to have the chance pressing the buttons once, not twice or more.
Dear Admin, I'm waiting for your reply.
Thank you
