Will my S21 FE 5G support the older devices such as gear S/S2/S3/frontier and classic

Howdy lads and lassies of the samsung community. I have a question for samsung, will my S21 FE 5G support the older devices such as gear S/S2/S3/frontier and classic as well as galaxy watch/ watch active/watch 2/watch 3/. Simply because it has sparked a question and because of newer wearables such as the watch 4 and watch 5 and 5 pro

I have a Galaxy S21 phone and put a PIN Lock Code on it and have regretted it ever since!!!
HOW can I get rid of it???

Head down to a repair shop like Phone repair guru if you're in Canada or just any repair shop in general
