My phone keeps freezing and crashing because of IOS 11.2 update

So I got the is iOS 11.2 yesterday, the day it was released, even though my phone didn't crash or freeze. The day after I get this update, my iPhone se starts to crash and freeze. My friends told me hers does the same thing (she has a iPhone 5 if that helps). So do you think the update or just our phones?

The update craze has gone and done it again, just as they do on computers. It's getting so that people probably should decline any opportunity to update anything, computers, phones, cars.

My iphone7 is constantly crashing after the update as well
