How to set Portrait mode?

Hello,
is it possible to set Portrait mode permanently for all apps?

Thank You.

Hi Mindaugas,

thanks for the patience, but it seems nobody knows a definite answer to your question. Did you try using apps like "Rotation Control"?

Best regards

Using the shell you could alter the screen rotation. Enter "settings put system user_rotation x" with x being 0 to 3 for all 4 possible rotations.
