Engineering menu touchscreen calibration. Simple and fast screen calibration on Android

After touchscreen smartphones replaced push-button phones from the gadget market, users were faced with a new problem. The sensor can " be dumb”, do not respond to requests, or even during a touch, open something that is not what the user needed, as if displacing him. In order to avoid such problems, the sensor must be calibrated.

Before you calibrate the sensor on Android, you must be sure of the accuracy of your actions. First, you have to check your smartphone for touch errors. Turn on, for example, a message and press certain letters. If what you clicked appears on the screen, then no calibration is required. Well, if the symbols are different, then you need to configure your smartphone.

It is necessary to calibrate the sensor:

• Every month or two of using the smartphone (if you notice obvious changes in the behavior of the display)
• Gluing the glass to the display
• Having bought a smartphone second-hand or a new one
• After the fall, flooded with water
• After changing the touchscreen and screen
• After changing the protective film

How to manually calibrate the sensor on Android

It’s worth saying right away that a large number of gadgets can be configured completely differently, and perhaps you are the owner of such a smartphone. The manufacturer may change or even eliminate this setting in the smartphone. Below we will consider the option of setting up calibration in the usual way.

1. Go to settings, and there go to the “Phone Settings” tab.
2. Go to the “Phone calibration” tab.
3. After this, a cross with a target will appear on a white background in the middle of the screen. Click on it three times.
4. After this, the calibration will be completed. After this, check the sensor in the same way as described above.

Using apps

If your smartphone does not have the ability to configure screen calibration, you can use a special application. In this case, it will be identical as in the standard version, and you will need to do the same as in a smartphone with this built-in feature. Some similar applications give possibility of setting more precisely than "relatives".

To search for such applications, go to Google Play through the application, and enter “Screen calibration” in the search, and then select the one you need. Unfortunately, we cannot advise you on specific programs, since they will display differently on different devices. BUT, I personally recommend the applications I used!

An Android device can be configured in a variety of ways, and in particular, many utilities have been created to help with such a simple task. “MachScreen Calibration” is probably the most popular program in this case. Also, “Touchscreen Calibration” is an equally popular and simple option for sensor calibration.

Android screen calibration through the engineering menu

The most reliable and sure way to configure the correct operation of your screen!

• Go to "Challenges"
• Enter a special code (it may differ on different models, try it)
• *#*#3646633#*#* , *#*#4636#*#* ,*#15963#* or *#*#6484#*#*
• Next we find an item with screen calibration (different variations on different versions of Android, something with “Sensor”
• After going to the calibration submenu, press start
• If everything was done correctly, you will see the calibration result

Now in pictures. An example of entering the engineering menu is given at Xiaomi Mi5.

If none of the above access codes to the engineering menu are suitable, then watch the video instructions, it will definitely point you in the right direction!

Very often, users of Android OS devices encounter problems associated with unstable operation of smartphone/tablet sensors. For example, when you receive a call and you hold the device to your ear, the display does not lock and you accidentally press the call reset button. Or the opposite situation, when after a conversation the screen does not want to light up. This particular problem is caused by the proximity sensor not working properly.

In this article, we will tell users how to calibrate any device sensor and make it work normally.

In order not to deviate from the above, first of all we will consider setting up the proximity sensor. All manipulations will be performed on a device running Android 5.0.2, so there may be slight differences in instructions for different versions.

Calibration of proximity and lighting sensors

Method one

The first thing you need to do is get into the engineering menu of your device. To do this, we use a special program, for example, “Launch the MTK Engineering Menu”, which you can download from the specified

1. Download, install and launch the application.

2. After launch, switch to the tab called “Hardware Testing”
3. Scroll to the very bottom of the list and find the “Sensor” item here.
4. In the next window, select the item called “Light/Proximity Sensor”.
5. Click on PS Calibration and select Calibration.
By moving your hand over the sensor you can see how the PS value changes from small to large values. As the hand approaches, it should increase and vice versa. In addition, this value should change depending on the incidence of light on the sensor. If this happens, the sensor does not need calibration.

If it does not react at all, then place the smartphone on a horizontal surface and press the Do calibration button. After this, the message Calibration success will appear. The sensor should now work stably. If this does not happen, move on to the next method.

Method two

We will use a third party program "Proximity Sensor: Reset" which you can download

Download, install and run "Proximity sensor: Reset".

Click on the huge “Calibrate Sensor” button.

We cover our sensor with our hand and press the Next button.

Then remove your hand from the sensor and click Next again.

After this, click the red “Calibrate” button and confirm the action by clicking the “Confirm” button.

Then you will be asked to grant root rights to this program. We allow it and after a few seconds the device will reboot.

That's all. If after all these manipulations the proximity sensor continues to be “stupid,” then there is only one option left: take the smartphone to a service center, because we cannot do anything else ourselves.

Touchscreen calibration

Many users often encounter the following problem: when they tap on the screen, it either does not respond or perceives the touch in the “wrong place”. To deal with this problem, you need to calibrate the screen.

Method one

We will use a third party Touchscreen Calibration program that you can download

1. Download, install and launch the above application.

2. Press the blue "Calibrate" button.

3. The program will ask you to make one “tap” on the screen.

4. After a single click, you will need to make a double tap.

5. Then we will be required to make a long press.

6. The next step is to swipe your finger to the right on the display.

7. Then we place two fingers on the screen and move them towards each other, as if we want to make the image or text smaller.

8. Then we perform the opposite action, as if we wanted to enlarge the image.

9. The message Calibrate Successful will appear on the screen, which means everything was successful.

Method two

We use another popular program Display Calibration, which can be found at the specified

Download, install and launch Display Calibration.

Click the big blue "Calibrate" button.

When the process is complete, the message “Calibrate Successful” will appear, confirming the successful completion of calibration.

You can find many similar programs on the Internet that work on the same principle, so you shouldn’t have any problems with mastering them.

Accelerometer calibration (Gsensor)

We need an accelerometer to perform a number of important functions: it is responsible for the orientation of the device in space, it is used by many applications, etc. Thanks to this, we (gamers) can enjoy those games that use this feature. Most often it is, of course, racing. And if Gsensor is “dull”, then this will certainly upset us. However, let's leave this lyrical digression aside and get down to business.

Method one

In this case, we will use the engineering menu of the Android device.

1. Go to the engineering menu of the smartphone/tablet using the above-mentioned program.

2. Go to the "Hardware Testing" tab.
3. At the very bottom, find the “Sensor” item and click on it.
4. Select "Sensor calibration".
5. Next, click the “Gsensor Calibration” button.

6. The device must lie on a flat, horizontal surface. The current data should be equal to zero (I have irregularities on the back cover, so the readings in the screenshot are a little inaccurate). Press the “Calibrate (40% accuracy)” button and after a couple of seconds you will see the message “Operation Succeed”.

That's all, exit the engineering menu. The accelerometer is now calibrated.

Method two

Now we will perform the calibration using a third-party program called Accelerometer Calibration Free, the free full version of which you will find

Download, install and launch this application.

On the screen we will see a large crosshair with a green center, as well as a red ball. We turn our smartphone/tablet so that the ball rolls into the green zone, and then press the “Calibrate” button (a whole mini-game is created).

We are waiting for the process to complete.

Voila, you're done. Note that the advantage of this program is the automatic calibration of the accelerometer. It is very comfortable. In the future, you will not have to monitor the operation of Gsensora; if there is the slightest inaccuracy, the application will calibrate it itself.

Method three

There is another good application called Spirit Level, which, in addition to calibration, performs a number of additional useful functions. You can download the application

1. Download, install and launch Spirit Level.

2. Press the "CAL" button.

3. In the menu that appears, press the same button again in all five items.
4. A message like this will appear.

That's it, the device has been calibrated. Note that this program has three different skins, which visually makes it very interesting.

Magnetometer calibration

This sensor is necessary to determine the Earth's magnetic fields. Without it, no built-in or user-installed compass will work. This function will be useful for hunters, travelers, tourists, etc.

Method one

To calibrate the magnetometer, we will use the wonderful Compass application from the developer MacroPinch. Apart from calibration, which is just an additional feature, this application is a full-fledged compass. You can download the program

Download, install and launch the Compass application.

Click the "menu" button in the upper right corner of the screen.

In the list that appears, set the “calibration” slider to the active position.

All. Now the magnetometer will work perfectly.

Bottom line

1. Go to the application.

2. Press the "Quick TuneUp" button.

That's all. The program will “polish” almost all the device’s sensors in a few minutes and even calibrate the battery.

If you have any problems or questions during the sensor calibration process, describe them in the comments to the article, and we will definitely help you!

Actions that relate to the formulation - calibrating the Android screen include setting up the touch-type display in order to properly execute commands by the device by touching the sensor with a stylus or fingers. Without such a setup, the device will work, but a number of undesirable consequences will arise when operating the gadget.

Some owners of devices running the Android operating system that are equipped with touch screens may sometimes encounter the unwanted problem of “disobedience” of the screen. In other words, when you touch a certain point on the touchscreen with a stylus or finger, the gadget perceives it as a completely different command.

Or there are situations when the sensor executes commands only after the third or fourth attempt. As a rule, the cause of these problems is the incorrect operation of the screen itself, for which it is necessary to calibrate the touchscreen of the device.

Urgent and correct calibration of the touchscreen on Android may be required in almost all cases if the smartphone has been dropped from any height, and after the device accidentally falls into the aquatic environment, this procedure is mandatory.

Also, calibration of the sensor on Android will be required after repair work on replacing the screen, the appearance of a water stain under the glass of the screen, and after suffering other, at first glance, minor damage.

To check the need for this procedure, you must perform the following steps:

1. Remove the special film protecting the screen (to ensure maximum correct operation of the sensor);
2. Enter any letter or number;
3. If there is a discrepancy between the button pressed on the gadget screen and the information typed, setting up the touchscreen is necessary.

Basic calibration methods

Two methods are used to bring a sensor-sensor that has been knocked out of its normal position into compliance.

These main methods include:

• Using special programs for the Android system;
• Self-correction.

It should be noted that for many brands (Samsung, HTC, Nokia and other Android devices) the calibration steps are practically no different from each other and are identical.

Manufacturers of Android devices, as a rule, can use two types of sensor:

• Resistive (with a screen made using this technology, all sorts of problems very often arise, so the setting is more in demand here, but such screens are practically not used today - these systems can only be seen in budget or already outdated models);
• Capacitive (used in most gadgets, it is more reliable and of higher quality).

Touchscreen calibration using Android

If you do not have access to the Google Play assortment, the display of your Android device can be configured in another way without any problems.

Step-by-step instructions in this case might look like this:

1. Go to the “Settings” menu in the gadget;
2. Select “Phone settings;
3. Find the inscription “Calibration, press the button;
4. A cross target with a dot inside will appear on the screen;
5. Click on this center of the target that appears at least three times.

After these steps, the device will automatically remember the touches. Thus, the calibration will be considered completed. After completing the setup procedure, you need to check the operation of the touchscreen by pressing a certain character on the screen, which should appear after its input.

Android screen calibration apps

You can configure the sensor using special software. The necessary software to successfully carry out this process can be found freely and freely available on the Internet.

The programs are quite simple to install and operate. But the most important thing is that you can get a positive and effective result from using almost any of them. In the Google Play store you can find free software applications such as Bubble and many others.

Application
This program has an excellent interface and also has some additional special features. Advantages of the application:

• Bubble is a free program;
• Works great with tablets and smartphones;
• Advertising can be disabled in the settings, or it can be left to encourage developers;
• Excellent graphics;
• The presence in the application of a special display that displays the angle of inclination with the highest accuracy in fractions of a degree;
• Easy to use;
• Possibility to fix the angle with a gesture or click;
• The presence of a sound signal at the zero position of the angle;
• If necessary, the ability to lock the screen orientation (horizontal or vertical);
• Ability to reinstall the application on the SD card;
• Disabling, if necessary, the “sleep” mode while the program is running;
• Using full screen mode.

Using the program is completely easy. To do this, after the initial launch, you need to select the type of device screen orientation in the settings (or set the “Auto” mode) and perform level calibration.
To do this, place the phone horizontally and press the calibration button on the left of the screen for a short time. “Calidbration” should appear on the touchscreen, and then “Wait”. The application will be ready to function when the screen displays a zero degree value.

The application is a program that allows you to configure the screen parameters of a touch device, while increasing its sensitivity and efficiency. Advantages:

• When using a protective film on the touchscreen, this application can significantly improve the sensitivity of the sensor;
• The slowing effect of using a protective film is eliminated;
• When using a device such as a stylus, some kind of tuning of the gadget becomes simply necessary with the help of this program. Using this application, you can enable complete ignoring of even palm touches (after setting, the hand can rest on the screen when using the stylus);
• If you need to use different settings, you can create separate shortcuts to quickly launch the application;
• The application has a free version.

The program is a professional tool for fine-tuning the level on an iPhone or iPodTouch. The application is used to solve ordinary problems or in more complex areas of use where the tilt of the device needs to be measured quite accurately. Advantages:

• The possibility of full-screen mode, which allows you to switch by clicking on the lower and upper arrows located in the middle of the gadget screen;
• Advanced two-way calibration allowing adjustments on surfaces that are far from level. Any direction is calibrated separately in order to obtain the required accuracy;
• Possibility of free download;

Possible calibration problems

If, however, the device is not calibrated using the method chosen for this purpose, or the application used does not give the necessary positive changes, then experts recommend trying another program; fortunately, there are quite a lot of them, software in this direction is very diverse. You can also try “Hard reboot” or in other words rebooting the device.

The last option for calibration is to contact a service center. A similar problem with the device screen can be caused not only by incorrect settings, but also by more serious reasons. In particular, in hardware failure of device elements or the presence of manufacturing defects. In this case, it is more advisable to contact specialists to troubleshoot the problem.

It should also be noted that, together with screen calibration, the gadget may need to check and adjust the screen sensitivity parameters for its subsequent high-quality operation.

Article Description

Hello Mi fans!!! I think that many have encountered such a nuisance as a decrease in screen sensitivity. A phone's touchscreen stops responding in two main scenarios: a hardware failure or a software problem. Hardware problems are not easy to fix and usually require replacing the entire touchscreen. If the problem is with the software, then it can be fixed by following some simple rules, applying patches or some tweaks. Let's look at some tips to improve touchscreen sensitivity:1. Using calibration in the engineering menu. Almost all manufacturers provide a calibration tool in the phone's engineering menu. You can easily recalibrate the screen yourself if over time you see that your smartphone has lost sensitivity. Various factors affect the performance of our touch screens, please follow the instructions included with the calibration tool to ensure correct operation. Recalibration is not a complicated procedure and you can perform it easily. In most cases this will improve the performance of your screen. Useful: Xiaomi engineering menu - how to enter and configure2. Update to the latest firmware version. The updates provide fixes for some problematic parts of the software that previously caused the smartphone and its screen to not function or malfunction. Updates are released to improve phone performance and debug code issues. If you have any issues related to touch on your new phone, then check for an update and, if available, apply it. If the problem is software related, then there is a good chance that the manufacturer has released a solution for it. Check for update: settings → about phone → system update. Useful: If you do not receive updates. From MIUI8 to MIUI9.3. Clear your phone screen. There are also simpler reasons. For example, there are drops of grease and dirt on your screen that have accumulated during its use. Keeping your phone's screen clean can also affect its performance. Clean it regularly using a soft cloth and touchscreen liquid. This way you can keep your screens clean and sensitive enough to your touch. Useful: Screen cleaning spray.4. Use high-quality (thin) safety glass. Now there are a great variety of safety glasses on the market. I agree that thicker glasses provide additional protection for your screen, but... Choose a glass with a happy medium, that is, thick enough for protection, but not affecting its sensitivity (performance). It is important to choose one that will not reduce the sensitivity of the screen and At the same time, it will be able to protect your display from damage. Useful: How to protect our screens.5. Avoid bumps, falls and other tests of strength :) I think it’s no secret that the phone is not intended for driving nails, using a stand under a table leg for balance, etc. It is better not to put smartphones with a large display diagonal in the pockets of skinny jeans or trousers. Make sure you pull it out before you sit down. Your actions may bend and damage your phone and screen. If you often drop your phone, then consider 360 degree protection for your phone. And if you do damage the display, then this automatically turns into a hardware failure, which we discussed above. Useful: How to use a phone with a broken sensor. Today we have discussed with you several reasons affecting the sensitivity of the touch screen. What other problems with the display do you know and their solutions? You can also tell me in the comments whether my advice was useful. See you in the open spaces of MiCommunity.
