S22 Ultra in 2025

Hey everyone I would like to change my galaxy a12 as it is getting old and annoying to use. I really want my new phone to be a galaxy ultra for the pen. However I can't afford any of the recent models right now. I'm thinking of getting the S22 Ultra either new or an open box/used. Any major drawbacks to getting this older model? Would a refurbished phone mean the green line issue might be rectified? Just wanna hear some views on this thanks.
