How this guide was reviewed
The workflow was reviewed against hands-on phone-repair and device-inspection experience, then checked against the limits of current browser access. Browser observations, user-confirmed checks, and items that require operating-system, carrier, manufacturer, or physical inspection remain separate.
The symptom usually appears during calls
The proximity system helps prevent accidental screen touches when the phone is held to your face. If the display stays awake during a normal call, your cheek can trigger buttons, mute the call, or open controls.
Test the behavior during an actual call because a browser may not have access to the sensor on your device.
Remove anything covering the top sensor area
A misaligned screen protector, thick case lip, dirt, adhesive, or replacement screen component can interfere with the sensor area. Remove removable accessories and clean the upper front surface before drawing conclusions.
If the issue began immediately after a display repair, sensor alignment and replacement-part compatibility become especially relevant.
Compare wake behavior after moving the phone away
The screen should not only turn off near your face; it should also return when the phone moves away. A phone that stays black after the call moves away may have a different sensor or software problem than one that never turns off in the first place.
Continue the inspection
Keep testing with a second signal.
A useful diagnosis usually comes from comparing more than one symptom. These related guides can help you build a fuller picture.
