Proximity Sensor Not Working on Xiaomi 11T and 11T Pro : Fix

If you have used Xiaomi smartphones before, you may have heard of its proximity sensor. Although Xiaomi 11T and 11T Pro have it, the proximity sensor problems in Xiaomi can be found in many smartphones. It turns out that there are countless reports on forums, the Xiaomi community, and other avenues where users have reported problems with the proximity sensors on Xiaomi 11T and 11T Pro, and new users seem to be complaining about not stopping anything soon. .

Here we have discussed what a proximity sensor actually does and why the Xiaomi 11T and 11T Pro (among other Xiaomi phones) have problems with their proximity sensor. Finally, there are workarounds until there is a permanent solution, so follow this guide.

What is the proximity sensor on Xiaomi Mi 11T / 11T Pro?

For the uninitiated, your phone’s proximity sensor is something that turns off the lights on the screen when you hold the phone close to your ear while talking during a call. Illuminate the screen as soon as the user removes the phone from their ear (or any other obstruction). It is also used to detect facial features that can unlock the phone.

You are also responsible for keeping the screen off when in your pocket with your pocket mode. This prevents a lot of accidental touches, which touchscreen phones have suffered greatly in the past. It may seem like little things, but they do improve your user experience a bit.

Why is the proximity sensor not working on Xiaomi 11T and 11T Pro?

The Xiaomi 11T and 11T Pro do not use an optical proximity sensor, which is a real physical sensor. Instead, Xiaomi gets its digital mockup from a company called Elliptic Labs that allows it to mimic the operations of a physical proximity sensor without putting one under the hood.

This is essential for OEMs as it solves supply chain issues with physical proximity and provides virtual functionality for hardware that would ultimately add to the overall weight of the device.

The point is, the Elliptic Labs proximity sensor or virtual proximity detection has problems no matter which model you are using. Xiaomi has been using these virtual sensors since 201 *, which means that millions of users are probably facing the same problems.

Assuming that even you are facing this problem, the question is how to fix it. Well, here are some fixes, solutions, and troubleshooting methods that I have found useful for troubleshooting proximity sensors with Xiaomi 11T and 11T Pro, among others.

Wait for updates from Elliptical and Xiaomi

Xiaomi has partnered with Minghao Sensing to integrate virtual proximity (sensing) sensors into their smartphones, which will likely work for newer models and units. However, those with an older model with virtual detection from Elliptical Labs will have to wait for an update from Elliptical and / or Xiaomi on this. Xiaomi should release a software update in this case (more on this later).

Restart

If the proximity sensor suddenly stopped working out of nowhere, you can use this method as it could be a software bug. Just turn off your phone, wait a few minutes, and turn it on again. Check if your phone’s proximity sensor works or not.

Press the power button during a call

This is a workaround that I have come across. Since a faulty proximity sensor can cause problems during calls by preventing the screen from turning off, there are solutions you can use. When you’re on a call, make sure to press the power button to lock the phone. This turns off the screen so there are no more accidental touches when you’re on call.

Note that you will need to unlock the phone after the call ends, but it is definitely better than having to deal with faulty or faulty proximity sensors.

Clean dirt from sensor above

As you may know, a proximity sensor looks for obstacles to turn off the screen, such as when you are on a call and hold the phone to your ear or when the phone is in your pocket. Dirt on top of the sensor can damage it and this is where cleaning comes in.

You don’t need any tools or specialized chemicals, but a simple dry cloth will do. Just clean the top bezel of your phone. For reference, the proximity sensor is located next to the front camera. Then use a slightly damp cotton cloth to remove all traces of dirt and this should restore normal operation of the proximity sensor.

Update the software

According to Xiaomi, it could send OTA updates to the devices affected by the broken or faulty proximity sensor on Xiaomi 11T and 11T Pro using software updates. Both devices use software rather than hardware for proximity sensing, so a software update seems like a logical step to fix the bugs that messed up virtual sensing in the first place.

Recalibrate the proximity sensor

This is a method you can use to calibrate the proximity sensor if it is working but slightly off. Is that how it works.

  • You must enter the secret code in a dialer app: * # * 6484 # * # * as is.
  • Find Proximity Sensor Test in the list of options and tap on it.
  • Follow the onscreen instructions to guide you on how to test the proximity sensor.
  • You will be prompted to press three dots (or similar exercises) to calibrate the sensor.
  • Restart the phone and see if it made a difference or not.

Alternatively

You can also use your phone’s Settings app to dive into the test.

  • Go to Settings >> About Phone >> Kernel.
  • You must press “Kernel” 4 to 5 times in a row before it gives you access to the “Hardware Test” window.
  • Find the “proximity sensor” and run the test to determine if the sensor is bad or if recalibration will work.

Reset the phone

This particular method may work if there is a software problem that you cannot solve with the above-mentioned methods. You can reset the phone, which will erase all the data stored on your phone. Here’s how to reset your phone.

  • Remove the SD card / SIM card and back up the data before proceeding.
  • Open Settings and go to General Management >> Reset.
  • Then select “Factory data reset” or its synonym.
  • You will be asked to confirm, so select “Reset” again, type the password and hit the “Reset” button again and it will do the trick.
  • Restart the phone, set it up as a new one, and check if the proximity sensor problem is gone or not.

Take it to a technician

If you cannot maintain a broken proximity sensor on Xiaomi 11T and 11T Pro and want to repair it immediately, reporting it to a technician can help. A technician should be able to define specific ideas on your device and repair the software or replace the unit if covered.

Since there is no hardware sensor on board, there is no way for the technician to replace the component for the best results, but you should be able to find common ground based on your specific use case. Make sure you don’t attempt to repair a proximity sensor or any other component on your phone without knowing how, as it will cause more damage than fixing the problem.

Conclusion

So here are the solutions to solve the proximity sensor problems on 11T and 11t pro. I hope this article is helpful to you. Feel free to share your suggestions and comments below.

How do I turn on the proximity sensor?

From your Home screen, tap the Application screen icon. Find and tap Settings → About Phone → Diagnostics. Tap Test device → Ear proximity, and follow the on-screen instructions.

How do I know if my proximity sensor is working?

You can just make a phone call, then hold your hand on the screen – that should turn the screen black if the sensor is working. Taking your hand away should show the screen again. If that’s not happening, your proximity detector is probably going (or gone)

How do I calibrate my Xiaomi sensor?

In the CIT Menu, press on the 3 points in the upper right and then enter ” Proximity sensor calibration “. After that we will cover the proximity sensor until the «5» value of Proximity sensor test is set to 0. Then we press on the « Calibration » button in order to calibrate the proximity sensor of our Xiaomi.
