How is this phone feature not yet available in 2019?

Hmm. I can't believe with how technologically advanced 2019 is that there isn't an after theft feature on Smartphones that when stolen scream at 100 decibels,"I'M STOLEN! I'M
STOLEN!" Straight until the rightful owner gets his or her phone back and deactivates this very annoying feature. And phone cannot be broken or destroyed. No thief would want to be hearing the durable and indestructible phone scream "I'M STOLEN!" All day and all night long at 100 decibles. How is this not a feature yet?
