How to play minecraft correctly?

Yesterday I wanted to play minecraft with the keyboard on my cell phone. Everything went well with the connection, but it was super stupid when playing. W, A, S, D went other versions went on the keyboard. With the mouse it was mega stupid I had to hold down to look around, so all you could do with the mouse was like on a cell phone. How do you do the controls like on the pc?

Unfortunately, this is not possible on cell phones.
