Proximity sensor doesn't work but camera work.
So, I have recently bought a iPhone 7, and it seems that the screen is not the original one. The problem is that the front camera works great but the proximity sensor not. I have iOS 11 and in the preferences the option to disable or enable the automatic brightness of the screen it's gone... It's possible that the proximity sensors are broken and the device does not present that option because of that ?
Thanks for helping! I have attached a print screen from the iPhone.
Es esta una buena pregunta?
