Water damage
When I purchased my iPhone 11 it stated that my phone is waterproof and it’s not I never dropped my phone in water I guess it got moist in it from me taking my shower because I always keep my phone in the bathroom with me when I take my showers so I can hear if my phone rings and since it stated that my was waterproof which is the reason I purchased my iPhone in the first place and not that it’s not true what can be done about this
iPhone 8, iOS 16
