If your Redmi 10 stopped turning off the screen during calls or is permanently locked for no reason, the proximity sensor is a 90% problem, but before you carry the phone for repair, make sure it's not a software failure or contamination, and then you'll find all the tools you need to diagnose and fix the problem.

1.Exact location of proximity sensor in Xiaomi Redmi 10

The proximity sensor in Xiaomi Redmi 10 is integrated into the top display module along with the front camera, speaker and light sensor. Physically, it is a miniature infrared sensor that emits and picks up the reflected signal. It is not visible externally - it is hidden under the screen security glass, but its position can be determined by the characteristic holes in the frame of the phone.

Specific location:

• 📍 Right of the front camera (when looking at the phone screen facing you).
• 🔍 Under the black strip at the top of the display (near the speaker).
• 📏 At a distance of about 3-5 mm from the edge of the body.

Redmi 10 2022 and Redmi models 10C The location is identical, but in the Redmi 10 Prime, the sensor can be shifted 1-2 mm to the left due to a different speaker design. To accurately determine its position, shine a flashlight at an angle to the top of the screen - you will see a barely noticeable hole (diameter). ~1 mm), which is the sensor lens.

It's important to understand that the proximity sensor is not a single module, but part of a flexible display plume, which means that when it fails, it often requires the entire screen to be replaced, not just the sensor, but in some cases, the problem is solved by software or by cleaning the contacts.

2. What the proximity sensor looks like: photo and diagram

Visually the proximity sensor in Redmi 10 It is a tiny black square (size). ~2×2 It's located next to the light sensor (which regulates the brightness of the screen) and is often confused with it. Below are photos of the phone's interior design, where you can see the exact position of the sensor:

3. How to check the operation of the proximity sensor

Before you carry your phone for repair, make sure the problem is really the sensor, not the software failure. Here are 3 reliable ways to diagnose:

🔹 Method 1: Testing through the Engineering Menu

1. Open the Phone app and dial ##6484##.
2. Select Proximity Sensor (Proximity Sensor).
3. Raise your hand to the top of the screen – the value should change from 5.00 (no obstacle) to 0.00 (there is an obstacle).

🔹 Method 2: Checking through the application

Install Phone Doctor Plus or Sensor Test from Google Play. Run a proximity sensor test and the app will show you if the sensor is recording your movements.

🔹 Method 3: Manual test during a call

1. Call another phone (or use a voice assistant).
2. Hold the Redmi 10 to your ear, and the screen should go out.
3. Take the phone away, the screen will light up again.

⚠️ Warning: If the sensor doesn't respond in any of the tests, but the engineering menu shows changes in values, the problem may be in the firmware. Try resetting to factory settings or updating. MIUI.

Check the sensor through the engineering menu|Clean the top of the screen from dirt|Update firmware MIUI last-minute|Check your call settings (automatic blocking may be disabled)-->

4. Why does the proximity sensor fail?

There are several reasons why the proximity sensor in Xiaomi Redmi 10 may stop working, which can be divided into hardware and software:

🔧 Hardware causes:

• 💥 Mechanical damage (phone drop, hit on top of screen).
• 🌊 Moisture falling under glass or on the display plume.
• 🧹 Pollution of the sensor lens (dust, fat, remnants of the protective film).
• 🔌 Oxidation of contacts on a flexible plume.
• 🔥 Overheating (for example, after a long game or charging).

📱 Programmatic reasons:

• 🐛 Failure in MIUI (especially after updating).
• 📲 Conflict with applications (for example, launchers or modified firmware).
• 🔄 Incorrect settings (disabled automatic screen lock function).

📊 Failure statistics (according to service centers):

• 60% - mechanical damage (falls, impacts).
• 25% - contamination or oxidation of contacts.
• 10% - software failures.
• 5% - factory marriage (rarely found).

If the sensor stopped working after the phone fell or water hit, it will most likely require a replacement of the display module. MIUI — Try to roll back the firmware or reset the settings.

5. How to fix the proximity sensor yourself

If the diagnostics show that the sensor is not working due to contamination or poor contact, you can try to restore it to work at home. Attention: the following methods are only suitable for software failures or mild contamination.
