Update to 14.2 killed my phone - Isn't there a law suite about this

Since I update my iPhone 8 to IOS 14.2 my phone is garbage. totally lags for minutes when I am trying to text, my message won't even show in the typing box until seconds go by. Can't copy and paste anymore, phone lags big time and battery sucks. My thumb print no longer works and getting into my phone is a pain. So many things to list and not enough time. Dealt with apple care before and they are no help. Doesn't apple have law suites against them for making phones unusable upon update? I will never ever update again. They do this all the time and I am done. Now I need a new phone and it wont be an IPHONE!
