I think PINE's ordering page is very much clear that if that's the sort of thing you'd RMA for, they'd rather not have you as a customer. My understanding is they're making basically no profit on these early run PineBook Pros and PinePhones.

This is like an $800 laptop feel for a $200 laptop price. Minor defects are worth just living with. And eventually, you can always buy yourself a replacement screen too.
