Is it possible to calibrate the screen? O, L and m dont work in portrait position.
Unfortunately no. Try repairing the phone software and the phone should do it by itself.

Have tired that now. Same letters or numbers are dead
Then you need to send in the phone to a service center for repair. Contact your local Xperia Support for more information:
