How to Fix REDMI Note 15 Pro 5G Proximity Sensor (Screen Stays Black)

Testing the Proximity Sensor

• ⚙️ Navigate to Settings → About phone → Detailed info and specs.
• 👆 Tap the Kernel version five times to access the CIT (hardware test) menu.
• 🔬 Select the Elliptic sensor and tap retest.
• ✅ A value of +5 indicates the sensor is working correctly.
• ⚠️ A value of 0.0 signifies a hardware fault, requiring contact with Xiaomi customer support for repair.

Software Troubleshooting Steps

• 🔄 If the sensor shows +5 but still malfunctions, first restart the phone by holding the power and volume up buttons, then rebooting.
• 🧹 Next, clear the data for the Phone app and Phone Services app via Settings → Apps.
• 📞 After clearing data, test the sensor by making a call to see if the screen remains black.

Physical Fixes and Next Steps

• ✨ If software fixes don't resolve the issue, carefully clean the sensor area around the earpiece using a microfiber cloth or soft brush. Avoid metallic tools.
• 🛡️ If cleaning doesn't help, the screen protector may be interfering. Try removing or replacing it.
• 🛠️ If none of these steps resolve the proximity sensor issue, the device likely needs professional service from Xiaomi.
