I'm on an iPhone 6 with everything I'm using being Apple products. Today out of the blue I started getting the "cable or accessory is not certified" message pop up. My phone wasn't connected to anything so I though nothing of it. I would just hit dismiss and go about my day. Fast forward a few hours later and I'm trying to charge my phone but it's not taking any of the cables. I've tried the iPhone and iPad cables, all Apple products but nothing is working. I've restarted my phone, did a reboot (power + home button) and still nothing. Any suggestions to fix this?
