this accessory may not be supported
Hi,
My iphone 5c keeps coming up with this accessory may not be supported when plugged in to the wall charger. I have tried two different chargers and both come up with the same error (brand new chargers). My phone randomly switched its self off and restarted earlier today. The actual operating system within the phone is being slow and freezes when trying to unlock and after unlocking the phone. How do I fix it? Or will I need to take it to apple for a replacement?
Any Help would be grateful
Many Thanks
Jessica
