Buy apple care on your phone and get it repaired using apple care. If you do it within 60 days they don’t require you verification of the actual phone.
I’d advise you to keep a case on your phone in the future. If you can’t afford to buy a new phone outright with no inconvenience, then keep it in a case. It’s the same as insurance.
I doubt it’ll realistically affect the image quality. I would just move past it.
