Is your iPhone 17 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 17 proximity sensor for $140. 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 17 to our Santa Rosa shop and enjoy normal call behavior again.
