Is your Xiaomi device giving you problems with the proximity sensor? If the answer is yes, do not worry because you are not the only one. In the summer of 2021, thousands of people reported these types of problems with this part of their mobile device. So many were the people affected that even the company even opened an investigation to find out what were the causes of this problem that affected so many users.
If you want to know what have been the problems that has caused this error, as well as its possible solutions, you are in the right place to find out.
There have already been several people who have reported problems with the proximity sensor on Xiaomi phones in the latest models, but although they should, no mobile phone is perfect, let alone its designers. This problem has been something that has frustrated many of the company's users, since many times it prevented, for example, listening to the audio as a call.
What is the proximity sensor of the mobile and what is it used for?
The proximity sensor of a mobile device is used so that, while you have a phone call, the screen of our phone remains off so that we avoid hitting unwanted keys with our cheeks. This sensor is activated, therefore, when we bring the phone closer to the ear. It is located in the upper front part of our device, more specifically above the screen. Another of the functions of the proximity sensor is to be able to listen to the audios of the large communication platforms, such as WhatsApp or Telegram, privately as a call. When you go to listen to audio and bring the device closer to your face, the proximity sensor will automatically activate, allowing you to listen to the audio as a call.
Reasons why the proximity sensor may not work
Cases and screen protectors
In the first place, and although it may seem silly, the incorrect use of mobile protection cases It may be one of the reasons why your phone's proximity sensor is not working properly. A case that is not the model of our phone or that is poorly designed could interfere with the proper functioning of the proximity sensor of our device, covering it and making it useless. The same goes for tempered glass. A bad placement of tempered glass of our mobile can cause the proximity sensor to remain inactive. That is why it is very important that when placing our screen protector we go to an establishment specialized in mobile telephony.
Installing new ROMs
La installing new ROMs It could also give us problems with the topic to which we have been referring. But to solve this small problem, all we would have to do is go back to the old model that we were using previously. Another possible solution would be to locate a firmware that is compatible with your device.
damaged sensor
In the worst case we would have to sensor was damaged. The solution to this would be very expensive since it would involve completely changing the screen of our phone. That is why, although it may seem otherwise, it is an element that if badly injured, we would have to be willing to pay a high price if we want to continue enjoying the comfort it offers us. This is the case in most cases, but there may also be an establishment in your city where they can only change the sensor. For this reason, if you are ever unlucky enough to experience what we are telling you about, we encourage you to inform yourself before changing the entire screen on your phone.
sensor not calibrated
The last of the reasons would be that the sensor is not calibrated and you have to do it if you want to enjoy it. This task can only be done through software. To do this, there are several options, such as accessing the developer mode of your device, using an interface that we activate through a script or using a third-party application. In any of the cases we will always have to follow the indications of the interface so that our proximity sensor is correctly calibrated.
Models that are failing
Let's go back to the beginning, where we mentioned that thousands of people have been affected by this problem and that, based on this, Xiaomi carried out an investigation to find out what were the causes and the models affected by this error. This survey could be carried out by anyone, preferably those whose phone was of the brand. In it, she wondered about various topics such as when it fails, how often, what application the user uses to make calls... Thus, with the data collected, a solution could be reached and this problem could be corrected in subsequent devices. Indeed, a conclusion was reached and it was established that the models that could be causing problems were the following:
- I 10T
- Mi 10T Pro
- My 10T Lite
- Note me 10 Lite
- Redmi Note 10
- Notes redmi 10 Pro
These devices have visual sensor, while the sensor that could give less problems were the optical.
Solutions to proximity sensor failure
Possibly, if you are one of those affected or your device is on the list that we have mentioned in the previous section, you are interested in knowing what are some of the possible solutions that have been investigated on this subject over time.
Cleanliness: a key factor.
Cleaning is one of the most important elements for the correct maintenance of our proximity sensor, and which will be decisive when it comes to its proper functioning. You have to be especially careful with cleaning this area since it is quite prone to getting dirty, being one of the parts of the phone that has the most contact with our face. For this, you can always take it to a specialist in mobile technology. If you want a more economical and homemade solution, you can do it yourself using a microfiber cloth and isopropyl alcohol, always doing it with the greatest possible care so as not to further damage the sensor or your screen. You must be much more careful if dirt is embedded in your sensor.
Say goodbye to covers and protectors
If you look closely, you will be able to tell if the problem is caused by these elements. If so, you will need to dispose of the screen protector and/or phone case, as applicable. As we said at the beginning, problems with the proximity sensor are often caused by the covers that protect from more, interfering with the sensor, or the misplaced screen savers. Consequently, in case you remove any of these two elements, you will have to get one again. Of course, take a good look before buying them that the cover does not interfere with your sensor and that the tempered glass is well positioned.
Restart your device
It may seem that it is useless, but many times it is the most useful action we can take. Restarting our smartphone can help us to put back into operation some functions that had been "frozen". Once your phone has restarted, check if the problem is fixed and if so, you will not need to perform any further actions. If not, keep reading to find out more.
Check if the proximity sensor settings are correct.
Here are the steps you have to follow:
- Go to the settings of your Xiaomi device.
- Access the notifications tab.
- Access the system applications section.
- Select call settings.
- Lastly, select incoming call settings.
Next, you may be presented with the option to turn the proximity sensor on and off. To get it to work correctly, what we will have to do is disable it and after that we will restart our device. Next, we will have to repeat the steps and activate the option to get it working properly again.
update the phone
It is important that you know that when you get a mobile device which has just been released, It is possible that not fully polished, so you will have to use the new updates that are released in order to solve the possible errors that may be on your phone. These updates are usually notified to you, but if at a specific time you want to see if your phone has an update, you will have to follow these steps:
- Open the Settings app.
- Click on the About phone menu.
- Finally, click on MIUI.
Factory restore your smartphone
We advise you to do this as last option since nobody likes to return to the initial mode of the phone once we have customized it to our liking. It is very important that before restoring it you do a backup your phone so as not to lose absolutely anything and, once restored, to leave your phone as it was. To do this, you will have to go to your phone's settings, click on backup and reset and finally, delete everything. I know that it can hurt, in case we get something loose and lose it, but at least that way, once restored, our problems with the phone will be solved since it will return to factory mode.
