This happened to me this summer... the top camera lens cracked. I called Apple and they were useless, they told me they can’t replace such a small part and the only solution was to replace the whole handset in exchange of £700 (i don’t have apple care).
Of course I said no because this is ridiculous, I didn’t want a new phone I just wanted a new glass camera lens cap which is tiny and shouldn’t be that hard to replace.
In the meantime I stick tape to my camera to prevent dust and damage to the inner lens. I finally found a repair shop that had this tiny part in stock and was willing to replace it for me. Can you guess how much it cost me?
£50 😂
Not ideal but better than not being to use my camera at all. Also my phone was already out of warranty and because it was bought in the US no insurance company other than apple care wanted to insure my phone to begin with. This is just my bad luck...
Now I have a Spigen tempered glass camera protection, it doesn’t look as nice as when it’s without but at least it protects from this stupid thing happening again.
