During the call, the screen is blocked. Calibration of the approximation sensor on Xiaomi Redmi, Note, MI devices

Cell phones Gave us the luxury of communication, the possibility of obtaining information and entertainment anywhere. What device can be called perfect? Opinions will disperse, but reliability will prefer most of the users: to work everywhere, discharged slowly.

Manufacturers firms compete in the release of new products of modern powerful communicators. Their filling copes with video demonstration, allows you to open the pages of sites, as on a regular PC, spend leisure for full games. A set of functions of smartphones is really impressive.

• K.'s habit large smartphones With a convenient 5-6-inch displays, it appears quickly, it is no longer want to return to smaller models. Similar to the purchase of a car: Having tried a foreign car, a person is unlikely to be satisfied with the domestic car.
• The wide possibilities of smartphones as mini-computers in your pockets do not abolize phone functions. We are so accustomed to call from everywhere and always that even small malfunctions begin to annoy.
• In order to extend the service life of the apparatus without recharging, manufacturers made autofunction of the screen repayment when bringing to the ear. When the display of the phone does not go out when talking, the battery is discharged faster, and random clicks on the screen violate the conversation.

Technical ways to solve the disbelief sensor faults

In Smartphones S. touch screen The approximation sensor is located at the top of the front panel. This sensor is needed to save energy and eliminate the random triggering of the sensor during the conversation. When the phone is approached to the face during the conversation, the approximation sensor disables the display and sensor. If the sensor works incorrectly, the display either does not go out at all during the conversation, or it goes away at once at the beginning of the conversation, and it is impossible to finish the conversation. Correction options:

• Delete protective film, wipe the screen. Film or dirt on the front panel can lead to a disruption of the operation of the sensor.
• Make a general reset. This will help if the sensor is calibrated. Reset can return it to factory values, and the sensor will start working normally.
• Temporary solution - To turn on the display during a conversation, you can undermine the buttons, insert a headset or charging, the display will light up, and you can reset a call.
• If the problem is in the sensor itself, then it must be changed. DIY repair of phones by the user of such a defect is impossible. In our authorized SC, you will replace the sensor to the new one.

Pretty large number of users are faced with a problem when during the call, the phone goes out the screenAnd nothing can be done. At this point, the buttons do not work, including the power button, the sensor does not respond to any action, and single way Return everything to normal - so that at that end they removed or put the phone.

In most cases, this problem is associated with the approximation sensor. But there may be quite a lot of problems with it.

I came across such problems, I did not particularly read about them, until there was such a problem at the very time, twice. For the first time, this problem appeared with chinese copy SAMSUNG S5. The second time with Xiaomi Mi4. No, it's not about chinese phones, I just came out that way. When I was looking for information why my screen goes out during a call, I did not find such problems with Chinese replicas. As a rule, it was factory samsung, HTC, Nokia, and rarely Sony. Mentions of the extinguished screen during the call on Chinese devices I did not find. And it was strongly embarrassed me, since many advised to flash the device, and the Chinese device is difficult to flash.

However, by turning from the forums of users of phones to technical forums, I concluded that the problem is not in the firmware, but in the approximation sensor. The approximation sensor is installed on any modern phone. Its main function, when obstacles are detected at a certain distance (the obstacle is your cheek), it disables the screen to save energy, as well as blocks the buttons so that you do during the conversation, you accidentally pressed the unnecessary buttons with cheek or fingers. After you talked, and removed the phone from the ear, the sensor discovers that there is no obstacle, and unlocks the phone for further use. This is if simple words. And when there are any problems with the sensor of the approximation, then the RED Time Call comes output, and you can not do anything.

As a rule, such problems happen for several reasons.

The first reason is the phones after repair. Non-certified centers, and many private traders, forget to wear a gum on the sensor, either put on its crooked, as a result of which, in the first version, the sensor hangs freely, and falls into the dead zones under the plastic; In the second case, the rubber band overlaps the approximation sensor. In these cases, the optimal option is to attribute the phone back to the Mount Master and make it all make it normal. You can try to disassemble yourself, but I am not a lover to disassemble the devices where there are no bolts.

The second reason lies in the non-tightly adjacent glass near the approximation sensor. As a result, the sensor "falls" to the edge of the glass, and seeing the "obstacle" blocks the system. This situation may occur at any time, starting from buying a phone, during its operation, and ending with a drop or impact. This problem was in the Chinese replica SAMSUNG S5.. I was advised to attribute to the workshop, where I sold the faucet to the corps for 1000 rubles. This is exactly what my friend did, it was with this model that this model is a frequent problem), but warned that after that the phone will not be presentable, but the screen will stop gossy during the call. The basis of the method is that the glass is pressed, the soldering iron swell plastic over it, and plastic, melting, passes on the glass. As you understand, then "Scar" will remain on the phone. I did not suit this method, and I decided to experience another, which I cost 76 rubles. I just bought a super moment. He took plastic from the packaging of the super moment, the plastic is needed in order not to absorb glue. Capped a drop of glue into cardboard from the same glue packaging. Thereafter. I touched the plastic to this drop. The plastic remains a small amount of glue. After that, I, this part of the plastic spent on the protruding rear part of the glass and pressed it. Last minute, let go and checked the phone. The phone worked fine and the screen stopped to go out during the call. All this can be seen on the video at the end of the article.

Why did I do this algorithm? Just the laws of chemistry and physics, as well as desire not to spoil appearance Devices. If I picked up paper or cardboard, then the glue would have absorbed, and I practically did not affect anything. If I had dropped to a place where the glass was departed from the housing, then the drop would leak under the glass where it could sleep or glue the inner parts, and it would be blossomed from above, even if it was small, but the pieces of glass. And this is a "blossom" from which they do not get rid of, respectively, the appearance is spoiled. Also, during the press, all the extra glue would have to go somewhere, and this is only the inside, or the top of the glass. In my version, plastic from the package took exactly so much glue as I touched. The glue took the square that was supposed to be busy. After I began to lead, the end of the glass took only so much glue as it could accommodate the area of \u200b\u200bthis glass. By analogy with water, when you deliver something under a jet from the crane, and the water begins to run through this area (of course, if you did not turn on the pressure on the whole). Therefore, the glass took exactly so much glue as they had enough on its square, and nothing superfluous.

About the third option of the ovens the screen during the call, we will talk in the next article, on example Xiaomi. MI4.

Constantly active backlight during a conversation leads to many related problems: it starts to quickly discharge the battery, the extraneous buttons are pressed, and during the call there is no possibility to reset the call on time.

When the screen does not go out when conversation iPhoneYou should immediately determine the cause of the breakdown and eliminate it, otherwise the phone can be overheated.

Causes of malfunction

The type of repair (hardware or software) depends on the cause of the illumination problem. We understand the more detailed why the iPhone screen does not go out when talking. Allocate the following cases that could provoke a breakdown:

• Falling the phone. Even if the phone fell only once and no visible damage can be seen, it does not mean that they did not appear inside the case. Also, any deformation of the body can provoke a failure in the work of physical details of the device;
• Protective screen or film provoke unstable sensor operation. All these additional screens are made from various materials and some of them can interfere with the sensor to recognize movements. Remove the film or cover and wipe the approximation sensor with a dry clean napkin to establish its functionality. In the future, take the protectors for the hull from better and fine materials;
• Poor-quality repair. Perhaps recently you changed the camera or body. In consequence of non-professional actions, the wizard, the light filter could be damaged or the replaced part was fake;
• Fit inside phone large number moisture and condensate formation on the details. In this case, you should heal an iPhone, leaving it in a disassembled form for a day.

Reset

In practice, there are cases where the locked screen in the iPhone does not go out after SMS comes or system notice. In this case, you should simply reset the phone settings to the factory. After rebooting the device will work normally. So as not to lose user data, create in advance backup In iTunes or Icloud.

Replacing the approximation sensor

The approximation sensor is a component built into the iPhone that allows you to automatically determine the user's approach to the device during a conversation. When you bring the phone to the ear, the sensor automatically reveals this action and the backlight goes out so that other keys do not push. The broken sensor can not recognize the movements at all or determine them once.

If software solution methods did not help you eliminate the problem, you should replace the sensor to a new part. Note, the original approximation sensor should have a special UV radiation filter (the light-pink coating on the sensor is indicated). Pay attention to such a feature during the purchase of original components:

The location of the sensor of the approximation is indicated in the figure below:

Separately purchase the sensor can not. If the screen does not go out when the iPhone is conversation, you should replace frontal chamber. Its hardware configuration contains the approximation sensor.

Repair is that you need to disconnect the display module from the back of the housing. Then you should unscrew the front camera plug:

Perhaps the sensor simply got dust or dirt, so his work was failed. If so, you should clean the item with a dry cotton wand. If there is no contamination and the sensor does not work - continue the repair.

At the next stage, it is necessary to disconnect the camera with the help of a refrigerator and tweezers and replace it with a new part. So you will receive an updated motion sensor.

Why does the screen not go out on the phone when bringing to the ear? In this article, you will find information as in Xiaomy settings, enable the screen lock function when talking. If on yours smartphone Xiaomi. With an incoming or outgoing call, stopped to go out and blocked the screen when you bring the phone to the ear, then you may have been disabled in the Android settings this feature. It could happen quite by chance and you just did not notice or your children went through the phone settings and turned off the approximation sensor. In our example, we will show how to enable the approximation sensor on xyi redmi 4x so that when you brought the phone to the ear screen blocked and the GAS. Perhaps the information will come to other android smartphones and tablets.

So that the screen automatically blocked the screen when applying to the ear, you need to do the following actions. Open the phone on the Xiaomi icon and get there where we usually type the number for the call. Next, click on the touch button "Menu" in the form of three horizontal strips. (On some androids after opening the "Menu" phone, you can also open the touch button in the form of a three stripes located under the screen on the left side. This button must be pressed and hold a little menu.) See below for attached pictures where the desired icons are highlighted and Buttons.

Next, in the menu window that opens, you select incoming calls under which there will be a short description of possible settings ( additional settings Device behavior with incoming challenges).

In the settings "Incoming calls" we find and choose an item Proximity sensor Under which it will be written (disable the screen automatically when the phone is raised to the ear during a conversation) and turn it on. Ready, Now that you bring the phone to the ear, the screen will go out and will be blocked, thereby preventing random pressing and touching to the touchscreen.
