Is your iPhone 12 Mini screen not turning off during calls? Does the display stay on when you put the phone to your ear? That is a failing proximity sensor. At My Cell Repair in Santa Rosa, California, we repair the iPhone 12 Mini proximity sensor for $130. This small but important sensor detects when your phone is against your face and turns off the screen to prevent accidental touches. We will diagnose the issue, replace the sensor if needed, and test it thoroughly. Most repairs are done the same day. Bring your iPhone 12 Mini to our Santa Rosa shop and enjoy normal call behavior again.
