Good microwaves have a microphone to detect popping. Popcorn option on microwave is a real feature.

Just do not buy cheap Amazon junk!

It used to be a real feature, but so many microwave makers made fake ones that popcorn sellers have been printing “do not use the popcorn button ” on their instructions for a while.

Then a microwave manufacturer says "do not worry about the warning saying do not use popcorn mode because our one works!"

But in seriousness don't rely on any auto turn off feature if it failing means a fire!
