How to prevent mistakenly locked iPhone due to holding with fingers on screen as entering passcode?

My iPhone has been locked twice during train ride when I was using train App. 

I was holding iPhone in my palm with fingers touching screen. Could train movement while I was standing cause iPhone to think I was trying to enter passcode?

i need help with preventing future recurrence because without accessing train App, I lost its direction information. I had to wait for the 15 minutes before iPhone unlocked.

my workaround is to disable Assessibility-Touch-Tap_to_Wake which is not ideal but my problem stopped.

Assessibility-Touch-Touch_Accomodations_Hold_Duration unfortunately cannot be less than 0.10 seconds which is too slow for operation other than Tap_to_Wake.

if only Tap_to_Wake has a dedicated Hold Duration, that may be my solution.

Keep the iPhone screen locked when not in use.


When you're moving around with your iPhone in your hand or in your pocket, the buttons on the side of the phone can be easily pressed, which can accidentally dial a number.


This is especially likely if you have a case on your phone that makes the buttons more sensitive. Use a case with a folio cover: This will help to protect the buttons on your phone and prevent them from being accidentally pressed.
