Experiencing screen delays or unexpected behavior during calls? Our skilled technicians at Apple Gadgets Care will recalibrate and restore your iPhone 16’s proximity sensor with precision; ensuring it performs flawlessly.
| Possible Issues | Possible reasons |
| Screen stays on during calls | Accidental drops can cause the proximity sensor to shift out of alignment or sustain damage, resulting in unresponsive screen behavior during calls. A precise repair or sensor module replacement typically restores full functionality and responsiveness. |
| Screen turns off randomly or too early | This issue may arise from several factors, including calibration inconsistencies, interference from an incompatible screen protector, or underlying iOS software glitches affecting sensor performance. |
| Auto-brightness not working properly | A malfunction in the integrated proximity and ambient light sensor can impair screen dimming, auto-brightness, and in-call responsiveness. This often stems from sensor wear, internal component damage, or signal disruption caused by logic board-related faults. |
| Screen won’t wake when moved or lifted | This usually occurs when moisture gets inside the devices affecting the sensors components or when the internal connects come loose or becomes corroded which disrupts the signal flow between the sensor and the logic board |
| Face-down detection not triggering screen off | Dust buildup, debris intrusion, or misaligned screen protectors can obstruct the proximity sensor, resulting in unreliable screen behavior. Additionally, software glitches or iOS-related bugs may interfere with sensor calibration, leading to inconsistent or delayed responses. |
Yes, the iPhone 16 features a combined module. A fault in one part can affect both screen dimming and proximity detection. Which is why if an issue with the proximity sensor occurs and we find it during the diagnostic, we advise a full replacement.
It detects your movement in short. So actions like when the phone is near your face during calls the phone automatically turns off its screen to prevent accidental touches. It also saves battery as well. There are other features as well like auto-brightness and screen wake behaviour.
Symptoms usually range from, screen waking up randomly or in calls the screen stays awake. This issue is very frustrating and ruins the experience of using a flagship device which is why a replacement is advised most of the time to restore its factory standards.
If it is due to a logic board it will be found when we do a diagnostic of the phone and we will inform you about the issue and proceed accordingly.
Sometimes maybe yes but not always and it might require a professional diagnostic to find out the actual cause and then move forward to its solution.
