I searched security for pocket dial but it did not show

What do you see under Security -> Screen Lock? Can you try in Settings, on the search bar there, try searching Pocket Dial.

Thanks for your response. However, there is no Pocket Dial Prevention Mode option under Security-Screen Lock-

Hi FH. Please check Settings -> Security -> Screen Lock -> Pocket Dial Prevention Mode. Let me know if you find it.
