How to Test the Proximity Sensor on a POCO M8 5G

Understanding the Proximity Sensor

• 💡 The proximity sensor detects when you hold your phone near your ear during calls, turning off the screen to prevent accidental touches.
• ⚠️ Common symptoms of a malfunctioning sensor include the screen remaining black after pulling the phone away from your ear.

Accessing the Diagnostic Menu

• ⚙️ Navigate to Settings on your POCO M8 5G.
• 📱 Select About phone, then tap on Detailed info/specs.
• 👆 Repeatedly tap on the Kernel version until a hidden test menu appears.

Running the Proximity Sensor Test

• 🔬 Within the test menu, select the Proximity Sensor test.
• ✋ To simulate a call, cover the top of the phone with your hand or bring it close to your ear.
• ✅ Observe the screen for a Pass or Fail result to determine if the sensor is functioning correctly.

Troubleshooting and Next Steps

• ✨ If the test fails, first try cleaning the sensor area on the top of your phone with a microfiber cloth.
• 🛠️ If cleaning doesn't resolve the issue, consider visiting a service center for professional repair.
