iPhone speaker accidentally grill damage it is possible to
Repair
hi bro, at apple service center they may replace entire iPhone body to fix it. you may ask once at nearest apple service center. if you find it too expensive, then you may check with third party service center.
Important thing is, once device serviced outside, we wont be able to service it again at apple service center bro.
So if the damage is severe you may go with this option.
iPhone easly water affect are not bro still it’s water proof
none of the iPhones are water proof bro. but they are water resistant. so basic water splash and contact wont be an issue.
at apple service center they replace the adhesives to protect from water damage. but again its not water proof. its just water resistance for basic protection.
