I understand the scepticism, I was doubtful at first. But I’m incredibly careful with my stuff - I’ve only had three laptops in about 15 years, have never smashed a phone screen, and I treat my Switch similarly, it’s handled with kid gloves, has a quality screen protector, lives in the dock when not playing and when it rarely travels it’s in a proper padded hard case, so I really don’t think I’ve damaged it. And even though it’s second hand, I know the guy I bought it from - I would say at most it’s seen 300 hours playtime, probably closer to 200, with Celeste being the most intense / potentially liable to put the sticks under duress. So something is fucking up, and I swear it wasn’t me.
I’ll try all the home fixes people have suggested, ta.
