They must show youthe port condition and the result with an original accessory.

Ask the accessory maker
What they doIf the accessory is not Apple's, its maker confirms which iPhone models and iOS versions it supports.
They must show youthe compatibility list.
In writingwhether the accessory is certified and whether they replace it.

Clean, undamaged connectors
No special tools
Procedure
- Who:
- you, with the iPhone off and no metal tools.
- How:
- disconnect and reconnect the accessory. If the alert stays, look in good light at the accessory connector and the iPhone port; gently remove any debris you see and try again.
- Result that matters:
- whether there is debris or damage and whether the alert goes away after cleaning.
- If it goes away:
- debris was preventing good contact.
- If you see damage, the alert stays, or it appears with nothing connected:
- the iPhone needs a technical check.
- Evidence to keep:
- a photo of the connector and port before and after.
Apple says to remove debris gently. Do not push metal objects or liquids into the port; if there is damage, let service check it.
