New iPhone "This Accessory is not supported"
Hello forums,
I just bought a new (refurbished) iPhone 7. The headphone adapter that came with the phone works for a minute or so before throwing an error message "This Accessory is not supported". Apple support said to update the phone so I did, i'm currently on the newest iOS version iOS 11.3.1 and the phone still throws the error message. This is with the official adapter that came with the phone. Any chance I can fix this without having to buy a new adapter? If so I'd rather just get rid of the phone while I can and go with something else. I'd like to play music through my car aux. Thank you!
