On this page you will find information on how to enable or disable the auto answer of an incoming call on Xiaomi. You can set up your smartphone so that when you receive a call, your phone automatically answers the call. Also, many do not know how to disable auto-reply on Android, it is not necessary that you activated this feature yourself, perhaps it happened by accident or the children poked around in the phone settings and turned it on. If necessary, you can select certain settings in the auto answer settings, for example, when using a headset. In our example, we will see how to get into the auto-answer settings on Xiaomi Redmi 4X, perhaps the information will work for other Android smartphones and tablets.

Let's see how to enable or disable auto-reply on Xiaomi. Open the phone icon and get to where we usually dial the number to call. We press the touch menu button in the form of three horizontal stripes as shown below in the attached screenshot. (On some Android devices, after opening the phone, you can open the menu touch button in the form of three stripes, which will be located under the screen on the left side. This button must be pressed and held for a while to bring up the menu.) Below, look at the attached pictures, where the necessary icons and buttons are highlighted.

Now we get to the phone menu on Xiaomi where we need to find and select the Auto answer item, after which we see the possible auto answer settings.

Now you can enable auto answer on Xiaomi by activating Auto answer (answer calls automatically). If you need to turn off auto answer for an incoming call to Xiaomi, then just turn it off. You can also configure the possible actions for auto-answering an incoming call. For example, delaying the response so that you can cancel first incoming call or you can set the auto-reply mode on Xiaomi by selecting always accept automatically incoming call, headset only, Bluetooth only, etc.

Everyone has it modern smartphone on the Android based or iOS there are many interesting possibilities. Every year, devices are equipped with more and more sophisticated features that make it easier to work with the phone. One of the features of smartphones are sensors, of which there are more than a dozen. Xiaomi has a lot of them too.

Long-term operation of the device leads to a malfunction of sensors and sensors. Because of this, the automatic screen brightness may not be correctly adjusted at different times of the day, there will be problems when tapping the screen, since touches are detected incorrectly.

As for smartphones, calibrating the Xiaomi proximity sensor will help fix the problem. This procedure allows you to adjust the responses of the sensors to the correct answer, also with other types of sensors. It is worth noting that devices of other companies do not have such a function.

How to calibrate the proximity sensor on xiaomi

On most Xiaomi smartphones, you can use engineering menu, which contains the necessary sensor tests. But first you need to check the activity of the proximity sensor:

• Open the "Phone" section, click on the "Menu" on the left.
• Go to "Settings".
• We find the item "Incoming calls".
• In this section, we look at the line "Proximity sensor", the function must be active.
• Open the dialing menu and enter the standard engineering menu code: *#*#6484#*#*.
• We immediately get into the QC test window. Here we find the item "Proximity Sensor".
• We try to bring your finger closer to the sensor on top panel devices. If the "Value" value changes, then the sensor is OK.
• Click "Calibration" button to calibrate the proximity sensor on Xiaomi.

Battery calibration

Why do you need to calibrate the battery of Xiaomi smartphones?

During prolonged use of the phone, the information about fully charged and battery discharge may be incorrect, as a result, charging the smartphone may not be correct. This problem shortens battery life. To fix this, you will need to calibrate the battery.

The first calibration method is that the device must be fully charged when it is turned on and the following manipulations must be carried out:

• Disconnect the charging cable from the phone;
• Turn off your phone completely and reconnect the charging cable after a couple of seconds. The LED should be green;
• Disable again Charger and turn on the phone. After loading the OS, turn it off again. All actions are done very quickly;
• We start charging the switched off phone. As soon as the LED turns green, disconnect the smartphone from charging again.
• Turn on and use.

This was the easiest way to calibrate the battery on xiaomi.

The next method is to use Root rights. To do this, you need to prepare by reading each paragraph of the instructions below:

• Completely turn off the smartphone and connect it to the charging cable. It is desirable that the adapter be plugged into an outlet.
• After the device's LED turns green, the device must be turned on and wait for the operating system to fully load.
• Further actions will work if you have superuser rights. Download the application "Root Explorer".
• Go to the data / system directory and find the batterystats.bin file, which we delete.
• Disconnect the charger and use the smartphone until it automatically turns off.
• We charge the phone up to 100%.

Now the battery smartphone xiaomi fully calibrated and the system "remembered" the exact value of the capacitance.

How to calibrate a compass

Almost any Xiaomi firmware has a built-in Compass application. Correct calibration compass passes as follows:

• Go to the smartphone settings and the "Installed applications" section;
• We find applications "Compass";
• Click the "Clear data" button to clear the cache;
• We overload the phone;
• We are looking for the compass application on the main screen. It is usually located in the "Tools" folder.
• By launching the Compass, we allow access to geodata.
• We act in accordance with the instructions on the screen (You need to perform a gesture in the form of a figure eight), while the smartphone is placed in a horizontal position.
• After calibration, vibration will occur and the compass itself will appear.

Screen calibration

If when you press the screen, the sensor does not respond well, or the touches are detected incorrectly, there is an opportunity to fix the problem. To do this, the sensor is calibrated. The process involves the following series of steps:

• To calibrate the screen, it is advisable to remove the protective film or glass, but this is only a recommendation;
• We go into the engineering menu by entering the command *#*#6484#*#*;
• We find the option "Touchpanel";
• Swipe your fingers across the screen as instructed.

It is possible to use specialized applications that can be downloaded from Play market. These include Touchscreen Calibration, Display Calibration and the like. We use them last.

Thus, we have considered two ways to calibrate the display. If it doesn't help, then the problem is elsewhere.

Other calibrations

There are many more sensors, but one of the most important is the accelerometer, which is responsible for orientation in space. In other words, if your screen rotation is not working correctly, there is probably a problem with the accelerometer.

Accelerometer calibration on a Xiaomi smartphone is carried out by two methods: using standard functions and an ordinary magnet.

In the first case, on some Xiaomi firmware in the settings there is an accelerometer calibration function. It is located in the "Display" settings. After that, the built-in feature will automatically configure the sensor.

The second method is to use a mechanical effect on the smartphone using a magnet. The method does not always work and should be used with caution (the magnet should not be highly magnetized).

We take a magnet and hold it on the back of the phone for 2 minutes. Between the objects it is desirable to put some kind of cloth or paper. After the procedure, we restart the device and check the performance of the accelerometer.

There is another calibration option using the engineering menu. We do everything in order:

• Enter the command * # * # 6484 # * # * to enter the engineering menu;
• We find the item "Accelerator" or "Accelerometer sensor";
• We tilt the phone in different directions: right, left, forward and backward. As soon as all the arrows appear, press the "Calibration" button;
• The message "Calibration success" should appear;
• Click OK;
• Now you need to twist the smartphone in a circle to calibrate the Magnetic Sensor. We hold the device in a horizontal or vertical position;
• We are waiting for vibrations and messages Finished.

Every year, smartphones become more complex and constantly updated with new features. In particular, MIUI 8 gadgets are equipped with various sensors to help you work. For example, for correct adjustment automatic brightness display and for turning it off during telephone conversation responds to the light sensor (proximity). Sometimes in his work there are problems associated with incorrect calibration: for example, if the sensor did not turn off the display during calls, the user may accidentally press something wrong with his ear. There can be many reasons for incorrect calibration. If a simple reboot of the smartphone did not fix the problem, let's explore the reasons for this.

1. Xiaomi Redmi 3 proximity sensor is disabled. It is quite simple to enable it (let's take the Xiaomi Redmi3s smartphone as an example): open the dialer, then hold down the menu and select the item in the list "Incoming calls". There you will see "Proximity sensor". It needs to be turned on. Due to the fact that Xiaomi has a huge variety of phone models and their firmware, it is impossible to indicate the exact location of this item. If this setting is missing, it might be worth looking elsewhere.
2. Also very common cause errors in the operation of the touch sensor on Mi Max or Redmi Note, the gadget lock function may be running, which does not allow it to turn on when the phone is in your pocket. Because of this, very often the Xiaomi 3S proximity sensor lags and is buggy. To disable it, you need to go to "Settings - Calls - Incoming calls", where you will see a slider that must be moved to turn off the feature.
3. In addition, physical obstacles, such as protective glass or film. Check if there are special holes on the film for this sensor, and if not, change the protection or make these holes yourself. Most often, the sensor is located near the earpiece and the front camera. A similar problem is most often created by universal or simply low-quality glasses and films, and therefore we recommend that you carefully check before buying whether all the holes are available.

Xiaomi Redmi Proximity Sensor Calibration

What to do if the proximity sensor does not work on your Redmi Note 3 anyway? It is necessary to calibrate the sensor - this method is one of the most common. To do this, first check if the sensor works at all: in the call menu, enter the code *#*#6484#*#* (without pressing the call button). You will see the engineering menu (we checked this way on Xiaomi Redmi 4 Pro and Xiaomi Redmi 3 Pro, if it didn’t work out, read the article on how to get into the engineering menu) with five buttons. You need to click on the top right with the inscription Single Item Test. Next, find the inscription below Proximity Sensor and click on it, you will be taken to the testing menu. This should show "Near" or "Far" when you close the sensor with your finger. If the sensor does not respond, then it is broken, and if the test is successful, you can calibrate the Xiaomi Redmi 3s proximity sensor:

• Turn off the device;
• Press the Volume + button and then the Power button. After vibration, release the buttons;
• You will see the Chinese menu. Click on the 中文 button at the bottom right of the Download 模式 button. The language will become English;
• Press PCBA Test at the top and see the engineering menu. We go to Proximity sensor;
• Lay the phone on a smooth horizontal surface after wiping the light sensor with a soft cloth;
• Avoid bright light on the smartphone;
• Press Calibration and wait while the sensor is being calibrated;
• When finished, you will see the inscription Successfully- the sensor has been successfully calibrated.

To check the correct operation, cover the sensor with something opaque (for example, with a finger) - the one on the screen should change to zero. After completing the test, press the button Pass, after which we get into the engineering menu and press Finish-Power OFF. Then you need to turn on the smartphone again as usual and check the correct operation of the sensor: when making a call, when you bring the phone to your ear, you need the sensor to turn off the display.

The proximity (light) sensor on Xiaomi is responsible for automatic adjustment brightness, as well as turning off the display during a call. A failure in its operation can cause a lot of inconvenience, for example, the display may stop turning off during calls, which will lead to accidental clicks, as well as increased battery consumption. The issue can be resolved by calibrating the proximity sensor.

The causes of failures can be different, so it’s worth it in the first place. If this does not help, then let's look at the options for solving the problem from the simplest to the most complex:

Is the sensor turned on?

Check first if the sensor is on. To do this, open the "Phone" application and hold down the left touch key in the form of three horizontal stripes. In the menu that opens, go to Incoming calls > Screen off during a call(proximity sensor). Depending on the smartphone model and MIUI version, the names of the menu items may differ slightly.

Turning off the pocket lock feature

Activating this feature is one of the causes of sensor failures. Again, it can turn off in different ways on different models. First of all, look in the menu "Incoming calls"

If you do not have such an item, then go to Settings > Lock screen and fingerprint > Advanced settings > Pocket mode and turn it off.

Removing physical obstacles

Another reason for sensor failures is a non-original protective glass or film on the screen. The sensor itself is located next to front camera and conversational speaker. There should be a hole in this place, if not, then you need to change the film or cut it yourself.

Proximity Sensor Calibration

If a the above methods did not help - it is worth calibrating the proximity sensor, but first check if it works at all. To do this, you need to call . In dialing mode, enter *#*#6484#*#* or *#*#4636#*#* and we see the following picture:

Here we are interested in the item “Single item Test”, open it and in a new window look for the item “Proximity Sensor”

A test will open where, when the sensor is covered with a finger, the inscription “Close” should appear. If you remove your finger, the inscription "Far" will appear. If the sensor does not respond, you need to carry the smartphone in service center, and if everything is in order, you can proceed to the calibration.

Step-by-step instruction:

After the process is completed, you will need to check the sensor for operability. We cover it with a finger or an opaque object: if the number "1" on the screen has changed to "0", then everything is in order. Now click on the “Pass” item to return to the engineering menu, and then “Finish”, after which the smartphone will turn off.

We turn on the device again and check the operation of the sensor by bringing the phone to your ear during a call - the display should turn off.

If the calibration did not help

There are times when calibration does not help. The reasons may be as follows:

• Problems with the firmware, for the correction of which it is worth reflashing the device
• Perhaps after the repair the display was replaced with a non-original one.
• Banal marriage - in this case, you are on the road to a service center or to the seller

Phones evolve from year to year, becoming more and more complex devices that have a dozen different sensors on board. Each of them is responsible for certain functions. For example, the proximity sensor is responsible for adjusting the auto-brightness of the screen and turning it off during a conversation, it is also called a light or ambient light sensor. Proximity Sensor Calibration xiaomi redmi or note devices will help to fix the incorrect operation of the sensor, which can cause a lot of problems for the owner of the smartphone, for example, accidental taps on the screen during a call. There may be several reasons for incorrect operation. If a banal reboot of the device does not help you, then let's look at the reasons according to their degree of complexity.

Turn on the light sensor

Your sensor may simply be off. To enable it, you need to take a few steps, consider xiaomi redmi 3s as an example.
Open the "phone" application (dialer in the common people)
Long press on the menu
In the list that opens, select "incoming calls"
Then we find in the list "proximity sensor" and enable it if it is disabled

Some xiaomi models may not have this option or given function will differ in location on the menu. Unfortunately, it is not possible to give a universal menu path due to the wide variety of models and firmwares.

Disable "harmful" features

The most common reason for a sensor not working correctly is the “pocket lock” function, the meaning of which is to prevent the screen from turning on when the smartphone is in your pocket. Because of this option, the light sensor often does not work correctly.

This problem is relevant for all xiaomi firmware, for some reason, engineers do not want to fix this problem or believe that everything works as it should, however, for some users, this function does not cause problems. To turn off Pocket Lock, you need to go to settings, then to "calls" and then to "incoming calls", there you can find a slider that turns off this feature.

What can interfere with the sensor

One of the reasons for a malfunctioning proximity sensor is physical interference in its operation, namely a protective film or glass. For example, this proximity sensor does not work for our employee on xiaomi redmi note 3 pro for this very reason. If you do not have holes for the light sensor, then you need to either change the film / glass or make this hole yourself. This sensor is usually located above the screen, next to the front camera and earpiece. This problem is usually caused by low-quality or universal films. Therefore, before buying a protective coating, be sure to check the presence of all holes.

Testing and calibrating the light sensor

Light Sensor Test

A fairly popular solution is to calibrate the sensor. xiaomi approximations devices. First you need to check the sensor’s performance in the phone, for this we dial the following numbers * # * # 6484 # * # * (you do not need to press the call button), thanks to this combination you will be taken to the engineering menu, tested on xiaomi mi4 and xiaomi redmi 3 pro , other ways to get there are described in our article about the engineering menu.
You will see 5 buttons on a black background.

Click on the top right, it should say "Single Item Test".

In the list of components, you need to find and select "Proximity Sensor", it is usually located almost at the very bottom.

In the test itself, the screen will display the inscription "far" or "close", closing and opening the light sensor (for example, with a finger), the inscription should change. If this does not happen, then this module out of order.
After this text, you can try to calibrate.

Light Sensor Calibration

Let's consider the calibration using the xiaomi redmi 3s smartphone as an example.

Turn off your smartphone completely.

Hold down the volume + button (increase the volume), and without releasing it, press the power button again. Your device should vibrate, after which the buttons can be released.

A menu will open in front of you, in 95% of cases it will be on Chinese(including xiaomi redmi 3s). You need to click on the "中文" button, it is located in bottom line to the right of the "download模式" button. After that, the menu language will change to English.

We click on the "PCBA test" button in the top line and the engineering menu opens in front of us.

If the touchscreen does not work, then use the "UP" and "DOWN" buttons to navigate to the "Proximity sensor" item and go into it.

Place your phone horizontally on a flat surface.

The light sensor should not be covered by anything (it is better to wipe it with a cloth).

Make sure your phone is not exposed to bright light.

Click on the calibration button "Calibration", the sensor will begin to calibrate.

After that, the inscription “Successfully” should appear, it means that the calibration was successfully completed.

Now you need to check the operation of this module, cover the light sensor with an opaque object, on the screen 1 should change to 0 and vice versa.

After that, you may need to press the "Pass" button, you will be taken back to the engineering menu, there we press "Finish", then "Power Off", the phone should turn off.

We turn on the phone and check the operation of the sensor. When making a call, the screen should turn off only when you bring the phone to your ear.
On our personal experience The correct operation of the xiaomi redmi 3 proximity sensor was completely restored in this way.

Wrong device firmware

If the calibration does not help, then the reason for the incorrect operation of the smartphone may be incorrect flashing, this applies not only to the light sensor. The problem is that new firmware incorrectly gets on the smartphone, getting the remaining garbage from the old firmware. This problem concerns the update method through the regular recovery (bootloader). The transition to new versions should be done through fastboot or by resetting all settings and user data (full wipe). Of the minuses this method it is worth noting that all your data and applications will be deleted, but all garbage will be deleted along with them.

Other reasons

If the previous methods did not have the desired effect, then the reason may be to replace the screen with a poor-quality one. Unfortunately, screen modules for xiaomi phones supplied with a light sensor. If you have already done a screen replacement in the service, then it is quite possible that, contrary to all the beliefs of the master, you just got a low-quality screen with a bad sensor. If from the beginning of the purchase itself your smartphone does not work correctly, then a simple marriage may be the reason. We advise you to contact the seller for further instructions.
