I have an iPhone SE with a broken back glass piece (top). There is some kind of flex cable underneath where the glass is supposed to be. Any ideas to what this can be?
It’s an antenna for wifi and carrier wireless.
Yup, as the guy above said it’s mainly your WiFi antenna, that is if your talking about the back of the phone at the top. If that’s the case I’d replace it and make sure it’s all sealed up before any dust, dirt etc get inside. It keeps the phone healthy to be clean inside :)
