how to set screen timeout as 'never' while this option is not on my setting

[LornaLu]

Hi, I'd like to set my phone screen lock as 'never' as I need it to on for 30 mins on zoom while used in exam. I found the 'screen timeout' setting, but the longest period is 10 minutes.  my phone is Samsung S23 Ultra

The screen will not lock whilst the phone is in use, so will remain on whilst on a call or when using apps of anytype.

@LornaLu On my Android phone in Settings>Display>Screen Timeout I have a button I can switch to Attentive Display which prevents the screen from switching off. Probably different on iPhones, but I wouldn't know.

@LornaLu There's an app in the Play Store called Caffeine that should help you.
