I’m probably preaching to the choir, but for those who don’t know, at least on an iPhone and I’m sure android has something similar, if you foresee the situation coming you can just hold the sleep/wake button for a few seconds (even while your phone is in your pocket) and it will require the passcode and not allow biometrics.
Edit: my memory, it’s the sleep/wake button and volume down. Similar to android as per the below.
