In my pocket or baghobag

How does my phone know it is in my pocket or bag?
A setting option is to ring louder if in my pocket or bag?
What's that about?
A lint sensor ?
THANKS

I am guessing the proximity sensor or the brightness sensor or both. So if you have a very large transparent bag, it might not work!

Thank you lost child
Your guess of Proximity sensor saisfies me.
The brightness sensor may not work well in places like Nuuk ,Greenland as they are only getting 3 hours of dayight a day this time of year
Thank you for taking the time to reply
