Specially and every time, you won’t need to block anything, if you set it up once. The vast majority of mobile devices running on the Android system have a proximity sensor. Its main function is to turn off the screen when an object approaches the location of this sensor (it is usually located next to the speaker and reacts to the approach of the device to the ear)
There can be two reasons for the fact that the screen remains active - either the proximity sensor is disabled at all, or it is not calibrated (not configured)
The first reason (turning on the proximity sensor) is solved as follows.
The figures below show in detail the buttons and the sequence of transition to each of the subfolders.
From the desktop, immediately click Settings, go to this menu, click System Applications, then select Phone.
Once in the Phone menu, select Incoming calls (Additional settings for device behavior during incoming calls) - that's what we need! We enter and, among other items, we find our device called the Proximity Sensor - we look at its status. If it is disabled, turn it on, if it is already enabled, exit back to the desktop menu and proceed immediately to eliminate the second reason - calibration.
In some phone models, you can immediately get to Incoming calls from the Calls menu, and then select the Proximity sensor, evaluate its on / off status or calibrate it.
But suppose we have the proximity sensor turned on, and the screen still does not turn off during the incoming exit. Let's calibrate the sensor.
Go to Settings and select Accessibility. Next, we see the Proximity Sensor Calibration item - click it and follow the instructions of the system.
If it is still not clear how to calibrate the proximity sensor, I suggest watching this video, in which this process is shown clearly -
If you have situations when unauthorized taps on the screen occur during a conversation (with your cheek, for example), and you have not yet solved this problem, then this review is for you.
My situation is a little different. I very often carry the phone in my pants or jeans pocket, while it lies there with the screen to the leg (in order not to accidentally break, there were already blows leading to a dent on the back metal cover). The sensitivity of the sensor is very high, at the level of the "thin gloves" mode, so that the thin fabric of the pockets is not an obstacle between the sensor and the leg. And there are many cases when a smartphone turns on the screen in your pocket. This is every incoming call. These are notifications. These are incoming SMS. And the problem is that while I take out the communication device from my pocket, I manage to press something with my foot. The Lenovo P780 didn't have this problem because GravityBox for Android version 4 allowed me to block the status bar on the lock screen, which was a lifesaver for me. For some reason, GravityBox for the "six" and "seven" does not give such an opportunity, so before answering the call, I can turn on the navigation (devouring battery life) or turn off Wi-Fi without noticing it (and then be perplexedly surprised by the mail that has ceased to synchronize ).
I figured out notifications and SMS quickly - now they signal their appearance with sound and LED, but the screen does not turn on.
With calls, the situation is more complicated, you can’t do without turning on the screen. No, in fact, you can do without a screen, but in order to uniquely identify calls, you will need to assign a unique melody to each contact, and then remember more than 300 matches. Yes, and three dozen correspondences will confuse me, so we take it as a postulate that a screen is still needed to receive an incoming voice call.
What to do, how to get rid of random "pocket" clicks? You can carry your phone in your trouser pocket with the screen facing out. And risk the same screen. You don't have to carry your phone in your trouser pockets at all. You can put a case on your smartphone, but I really don’t like cases (maximum bumper, and even then not always). Or you can use the Smart Call Screen Lock (SCSL) software.
I heard about this application quite by accident, I purposefully did not look for it. But I started to use it and gradually get used to it. I can recommend it to others, especially if the problem of accidental clicks during calls is relevant, but I can’t guarantee the comfort of using it. Why - I will explain a little later.
So, SCSL is an application for locking the screen during (and temporarily) phone calls.
The logic of the application is extremely simple: the smartphone's touchscreen is blocked throughout the entire duration of an incoming or outgoing voice call. At the same time, a lock icon is displayed on the screen, with a tap on which you can remove / set the lock. The operation of the proximity sensor is not affected in any way. The physical navigation buttons also remain fully functional.
But in the main and only function of the application lies its main drawback, namely: before performing any planned action during a call, you must first unlock the possibility of performing this action. Simply put, before turning on the speakerphone or ending a call (except when the interlocutor ends it), you have to click on the lock icon, which is an unnecessary action. That's why I mentioned the need to get used to the softinka. I remember trying in vain to end a conversation a couple of weeks ago, forgetting to use SCSL and not seeing the padlock icon on the screen reflecting the bright sun.
It is clear that with such a narrow functionality, the softphone does not have any visual information display, except for the aforementioned lock icon that appears during a call. When you start the SCSL application from the application menu, a form with settings immediately opens, divided into two tabs: "BASIC" and "PRO". Yes, in general, the soft is free, but the settings on the "PRO" tab can only be used after the developer's monetary incentive, which is quite expected and logical.
And I’ll immediately note that the free part of the soft in my case does not suit me at all, since it does not block the touchscreen during incoming calls.
The BASIC tab contains a switch to turn the application on and off. In addition to the switch, there are several options for setting the color of the lock icon and the shade of the screen when the touchscreen is locked: "Icon color", "Background color" and "Screen color". Also, the developer graciously allowed to change the action for locking / unlocking the touchscreen for free - instead of a simple tap on the lock, you can use a long or double press.
For softkey users who have appreciated its software brainchild, the developer gives a few more options for customizing the application.
Here, of course, it is more interesting. In my opinion, the most interesting is the ability to block the touchscreen on an incoming call and adjust the size and position on the screen of the icon for blocking / unblocking (switches "Block on incoming call", "Button size" and "Button position"). By default, the lock icon is located in the upper left corner. Personally, it’s not at all convenient for me to reach for it, so I moved it to a position just above the slider for accepting / dropping a call in the dialer. After playing around with the size, I realized that the one proposed by the developer suits me perfectly.
 The size of the lock icon is set by the slider in the range from 20 to 250 percent |
The very first option on the PRO tab is Smart Lock. This switch allows you to use the proximity sensor to lock / unlock, that is, in your pocket or near your head, the touchscreen will be locked, and the rest of the time it will be unlocked. But either my smartphone could not make friends with its proximity sensor with a soft, or the developer didn’t “finish” something, but my smart lock behaves stupidly. I had to turn it off. By the way, in the corresponding w3bsit3-dns.com thread, some users also write that this function does not work correctly. Well, let her, it didn’t hurt, and I wanted to.
I also came across the "Start unlocked" switch and the numerical parameter "Auto-block timeout on outgoing" in the topic. That is, an outgoing call begins with a touchscreen unlocked for a specified number of seconds (from 0 to 10 in increments of 0.5), providing the opportunity to turn on the speakerphone or record. But, of course, if there are problems with the proximity sensor, then it is better not to activate this switch.
There are some softs that are nice to use. Some of them are also useful. And there is a category of applications and purely pragmatic ones. SCSL falls into this category. The developer, of course, tried to bring some comfort by implementing the ability to customize the appearance and position of the lock icon. And the very purpose of SCSL - to protect the screen from accidental clicks during voice calls - is designed to make using a smartphone more comfortable. But along with comfort comes some discomfort, paradoxically. In general, if the problem that the softshell solves is in front of you and your gadget in full growth, then you should try SCSL. And let your gadget please you, and not vice versa.
On your android, when you call, the screen immediately goes blank and turns black? If so, then the problem is most likely with the proximity sensor in the phone.
This problem can appear in any phone, for example, sony xperia, mi xiaomi, lumiya, compact, samsung, asus, xiaomi xiaomi, but it has been noticed that most often the screen goes blank on sony z3.
Moreover, it happens that it goes out and does not turn on - this is no longer a joke. If this happens when answering a call or when making an outgoing call, then most often the culprit is the proximity sensor.
What is a sensor and how does it work in android? The proximity sensor has several functions, but the most important task is to automatically dim and illuminate the display during a voice call.
This is done by determining what is close to your face and phone. When the phone is close to your ear, the sensor detects your head and the screen turns off to save battery and to prevent accidental disconnection of the call.
In turn, when you take the phone away from your ear, the screen lights up so you can end the call or use other features (number pad, switch conversation to speaker, etc.).
When it comes to damage to the proximity sensor, the mechanism described above stops working, so the phone has no way of inferring whether it is currently near a face.
The problem with the proximity sensor usually manifests itself in the fact that the screen immediately turns off during a call and lights up only after a call, or vice versa - the screen does not turn off even if you put it on your face during a call.
Causes of problems with the proximity sensor when the screen goes blank during a call
The problem with the sensor can occur both in software and in purely mechanical damage.
If the problem is software related, you can often fix it yourself.
For example, by recalibrating the sensor, by restoring the phone to factory settings, or by reinstalling the software.
Screen calibration solves many problems. How to make it.
If the problem was the result, for example, of the phone falling, then there was probably mechanical damage to the sensor.
Often this also happens when there is a "tear-off" from the top of the case to the bottom of the phone (particularly on the Sony Xperia).
Of course, purely mechanical problems are best dealt with by sending the equipment in for service, because replacing the sensor is not easy.
The first solution is when the phone screen goes blank with an incoming call - remove the film or glass
First of all, remove the film or tempered glass from the phone screen. In some smartphones, due to their design, they may cover the sensor and cause an erroneous detection distance.
Very often, glass can also be the cause of problems with the proximity sensor - you can find tons of very cheap, low-quality products in stores that are not reliable.
By tearing off the tempered glass, you can restore the normal functioning of the sensor.
Of course, for some this may seem ridiculous, but uncle Google or Yandex will give you hundreds of records from their “warehouse”, where users complain about problems with the proximity sensor after gluing poor quality glass.
The second solution if the phone screen goes blank when answering a call is calibration
Sometimes the problem is a software update, for example, which for some reason contributes to the deregulation of the proximity sensor.
In this case, you can use a free application that, when installed in several steps, can calibrate the sensor, such as Proximity Sensor Reset.
Using it is not difficult - a wizard will guide you through the entire process, and at the end you must confirm the new calibration, which will reboot the phone.
After that, you can make sure that the calibration helped and now the phone screen does not turn off during a call.
The third solution when the phone screen goes blank during an outgoing call is restoring factory settings
Another option you can try is a factory reset on your phone.
Unfortunately, this option deletes all data from the phone, so be sure to copy files, photos, music, videos, contacts, SMS, and others to a safe place.
Then go to "Settings > Backup & Reset" and select "Factory Reset".
Depending on the brand and software version installed, the factory settings may also be located elsewhere.
After confirmation, the phone will reboot and all data will be deleted and the device settings will be reset to factory defaults.
When you turn on your phone for the first time, you need to re-enter the settings (language selection, sign in to your Google account, etc.).
After the operation is completed, make sure that the screen works properly during a call and does not turn off.
Fourth solution if the phone screen goes blank - turn off the sensor
If your phone is no longer under warranty, and all other solutions have not worked, then the sensor is probably physically damaged, so that the screen goes blank immediately after starting a call.
If you do not want to spend money on service, then turn off the screen off during a call.
As a result, the screen will be constantly lit during a call, and you can use the on-screen buttons to activate the speakerphone or remove the keypad.
The disadvantage of this solution is that when we speak with a lit screen, we can accidentally press the buttons.
In order to be able to disable the proximity sensor, you will need to install a special Xposed Framework module.
To do this, you need to get ROOT () to get administrative privileges,
Phone Screen Still Dimming - A Few Proven Tips
Some owners were helped by the option of cleaning the speaker mesh. Sometimes there is a motion sensor. Take a small brush and gently clean everything - it will help you too
Judging by the reviews, most often the screen goes blank when making calls on the sony z3 compact phone. Many people managed to solve this problem by pressing on the upper right corner (there should be a sensor there).
There are cases that on the Xperia Z3, with strong pressure on the top of the screen, even a click is heard inside and the problem disappears.
In some smartphones, there is an intelligent processing option in the call settings - try turning it off if you find it.
For Sony phones, the screen very often peels off from the case and such a problem arises - careful gluing solves it.
You can also disable the incall ui application in the application settings. If this does not help, then in the notification settings, try turning on notifications for this application.
Of course, other reasons are not ruled out, but I end here. As they say, than he could, he helped. Good luck.
Often, mobile device users are faced with the fact that during a call the screen lock does not work, which prevents involuntary pressing on the display. The problem in this case lies in the proximity sensor. There are several reasons for the incorrect operation of this element of the smartphone. Now we will figure out how to enable / disable the proximity sensor on Android, or configure it if necessary.
In this case, we are talking about a small contactless device that recognizes the approach of an object to the smartphone. As a result of the correct operation of this function, the gadget's display will turn off automatically when you bring the phone to your ear. This will prevent accidental pressing of the touch buttons during a call (for example, with your ear, finger or cheek).
In addition, the proximity sensor on Android can significantly save battery power, because when the screen is on while talking with another subscriber, the battery power is intensively consumed.
Enable or disable the proximity sensor on Android
As a rule, the sensor on the device is active by default. If in your case this is not the case, or this function was somehow disabled by accident, then it will not be difficult to enable it. This is done as follows: go to " Settings", find the section" System Applications", select the item" Phone»:
Then press " Incoming calls"and move the slider to the active position in the line" Proximity sensor” (on some gadgets you will need to check the box):
Depending on the smartphone model, the activation of the sensor will look a little different, for example, by opening the dialing field immediately, we call the call settings menu or by pressing the " Settings”, or by pressing and holding the hardware options button. And after that, as it was written above, in " Incoming calls» turn on the sensor:
If the question is about how to turn off the proximity sensor, then, accordingly, we go the same way and deactivate the function (uncheck).
How to set up (calibrate) the proximity sensor
This element is located at the top of the smartphone, usually to the left or right of the front camera lens:
On some models of Android devices, it can be seen with the naked eye, while on others it is quite difficult to detect. If, during a call, remove the phone from your ear, and then bring your finger closer to the front camera, then the display that goes out after that will tell you the location of the sensor.
It is quite possible that the reason for the incorrect operation of the sensor was an elementary ingress of dust on it. In this case, you can restore the normal operation of the function simply by cleaning the device - turn off the smartphone and blow it with compressed air. Then you need to restart your gadget and check if the sensor has recovered.
If this manipulation did not bring the desired result, then you can resort to sensor calibration, which is performed in several ways.
With the help of the system
We open " Settings", select the item" Special abilities” (on some devices “ Screen”), find the line “ Proximity Sensor Calibration»:
Then, we follow the system prompts step by step, let's see the video more clearly:
Through the engineering menu
Using the engineering menu, you can check the correct operation of the sensor, and, if necessary, calibrate it.
To do this, enter the following character set in the dialing field: *#*#3646633#*#* Now open the tab Hardware Testing»(equipment testing) and press the button « sensor”, choose “ Light/Proximity Sensor»(light/proximity sensor):
- Choose " PS Data Collection» (acquisition of proximity sensor data);
- In the next window select " Get One Data»;
- After the appearance of the number 0 "Apply a palm to the proximity sensor on your smartphone and press again" Get One Data»;
If as a result we see a number 255 , then our sensor is functioning normally.
For settings:
Choose " PS Calibration", then " Calibration". After that, without closing the sensor, click on "Calculate min value". After the inscription " Calculate succeed"bring a sheet of paper to the sensor at a distance of 2-3 centimeters and click on" Calculate max value", after which we need to click" Do Calibration"and restart the smartphone:
Using third party software
If all the previous methods did not help to normalize the sensor, then you can use the Proximity Sensor Reset application (for rooted devices).
Download and install the app from the Play Store. After starting, activate the big button " Calibrate Sensor". Now cover the proximity sensor with your hand and press " Next»:
Then you need to remove your hand and press again " Next", and then " Calibrate" And " Confirm". At the request of the system, we provide superuser rights (ROOT). After the performed actions, we are waiting for the completion of the reboot of the smartphone.
Now you know how to enable / disable / configure the proximity sensor on Android. However, if in your case the problem has not been resolved, then it is possible that you will need to calibrate the display or flash the smartphone. In addition, sometimes the sensor may not work correctly due to a hardware failure, then you cannot avoid contacting a service center for help.
If on Android the screen does not turn on after a call or does not go out during a call when you bring it to your ear, then you should look for the cause of the problem in work. If it breaks, the device cannot correctly determine the position in space, so the screen does not light up, but the phone works.

Screen issues when calling on Android
The main function of the proximity sensor is to automatically turn on and off the backlight during a call. This allows you to save battery power and avoid accidentally pressing your ear or cheek on the touch screen of your gadget.
If your Android device does not turn off during a call, or the screen does not turn on after the call is over, then you should look for a problem in the operation of the sensor. The reasons may be as follows:
- Poor visibility (covered / covered with a protective film or cover).
- Lack of RAM.
- Firmware issues.
- Moisture ingress.
- Mechanical impact and damage to the cable or other components.
Wipe the screen thoroughly before attempting software troubleshooting. Pay special attention to the upper part, where the proximity sensor is located. If a film or glass is pasted on the display, then over time they can lose their transparency and also interfere with the sensor.
Then check the call settings - perhaps the parameters are incorrectly set in them, and the sensor is simply turned off. This option is not available in all phones, but it's worth checking.
- Open the settings and go to the "My devices" or "Settings" section.
- On the Calls tab, make sure there is a check mark next to Proximity Sensor.
Increase Also, make sure that the system has enough RAM for the sensor to work. Open the list of applications in the settings and on the "Running" tab, see how much RAM the phone spends. If you find a shortage, close unnecessary applications.
If everything is set correctly in the settings, but the sensor does not work, back up important data and reset Android settings to factory state. If the problem persists even after a hard reset, then you will have to flash the phone. If no software methods, including flashing, have resolved the problem, it is recommended that you contact a service center to diagnose hardware problems.
Screen problems on Android after sleep mode
Another problem that may occur with the screen is that it does not turn on after sleep mode. It may or may not be black, but the phone works. If you are faced with such a situation, then know that the reasons can also be software and hardware in nature:
- Lack of RAM.
- Firmware issues.
- Incorrect operation of the power button.
- Mechanical impact (shock, fall).
- Moisture ingress into the case.
If the phone does not turn on, but vibrates when an incoming call or other actions are performed, then it is likely that the problem can be fixed without contacting a service center. Clean up RAM from unnecessary processes by shutting down currently unnecessary applications. If this does not help, back up important data and reset the system settings to the factory state.
Increase If a hard reset also did not fix the problem, you will have to flash the device. It is important not to forget to make a backup copy before any major operation to interfere with Android.
If the software methods did not help, it is recommended to contact the service center for diagnostics and phone repair. In case of problems with the power button, as well as after mechanical impact and moisture, it may be necessary to replace components.
