Calibrating the proximity sensor on your Poco X3 Pro can resolve issues like the screen not turning off during calls. The process involves accessing a hidden testing menu within your device settings.
Step-by-Step Guide to Proximity Sensor Calibration
Follow these instructions carefully to recalibrate your Poco X3 Pro's proximity sensor:
- Open Settings: Navigate to the main "Settings" application on your Poco X3 Pro.
- Access About Phone: Scroll down and tap on "About phone."
- View All Specs: Select "All specs" to view detailed information about your device.
- Enter CIT Menu: Locate the "Kernel version" entry. Tap on "Kernel version" several times rapidly. This action will open the CIT (QC Test) menu, which is a diagnostic tool for your device.
- Navigate to Additional Tools: Once in the CIT menu, tap the three dots usually found in the top-right corner of the screen. From the dropdown menu, select "Additional Tools."
- Select Proximity Sensor: Within "Additional Tools," find and tap on "Proximity Sensor."
- Initiate Calibration: Press the "Calibrate" button. The system will then recalibrate your proximity sensor.
After completing these steps, test your proximity sensor by making a call or playing an audio message to see if the screen now behaves as expected when brought close to your ear.
Why Calibrate Your Proximity Sensor?
The proximity sensor is a small but crucial component of your smartphone. It detects how close an object (like your ear or face) is to the screen. When it malfunctions, you might experience:
- Screen not turning off during calls: This can lead to accidental touches with your cheek, muting calls, hanging up, or activating other features.
- Screen remaining black after a call: Sometimes the screen won't turn back on immediately after you move the phone away from your ear.
- Issues with gestures or apps: Some applications use the proximity sensor for specific functions, which may not work correctly if the sensor is miscalibrated.
Environmental factors, screen protectors, or software glitches can sometimes affect the sensor's accuracy, making calibration a useful troubleshooting step.
