How to calibrate the mobile touch screen

It is clear that one of the most important points, or elements, and the one that we use the most throughout the day is the phone screen. Basically, because without it we would not be able to use the smartphone. Especially, because we not only see content or the notifications we receive, but we also interact thanks to this component, since we can write, enter applications, among other things. But what happens when the touch goes wrong?

It will not be the first time that we see how the forums or, many users, try to find a solution to the touch screen of their phone. From one day to the next, it can stop responding as it did the first day, or even suddenly change from one morning to the next. However, we can always calibrate the mobile screen so that it can work again without any problem. In addition, it will help us rule out that the error is due to something more serious, such as a hardware failure.

Therefore, we are going to see everything that we can calibrate the phone panel so that we can fix the problems with the panel of any mobile.

Check if it fails

The truth is that, before getting down to work, it will be better to test at what points the mobile touch screen fails, or if it is really giving us problems. For this, there are certain internal and third-party tools to be able to clear up any doubts. For example, the first one is found among the configuration of Android smartphones.

In addition, it is a foolproof method to know if the touch screen has problems. To access it we will have to go Settings > About Phone and press several times on Build number . At that time, we will activate the Developer Options , so we will have to enter to go to the indicated function.

When we’re inside, look for the Pointer Location feature and flip its switch. At that moment, we will see some horizontal and vertical lines, which will mark our journey through the phone as we touch the touch screen of the mobile with our finger. This allows us to accurately test all points on the display. In the event that we see interruptions in the lines, we will know for sure that the panel is failing and, above all, we will be able to find out exactly where the error is.

Calibrate the screen

In order to recalibrate the screen of a mobile, we will need the help of a third-party app that will help us, and a lot. Basically, because this software that we can download on Google Play allows us to solve different touch screen problems, such as calibration .

The most common symptoms that will warn us that something is not going as it should be are the famous ghost touches , that touch commands are executed without having touched the smartphone display, or more touches than we actually give on the terminal panel. Nor should we forget about the different delays in the touches or, even, that they never get executed.

When we install it on the device, the truth is that there is no loss, that is, we only have to enter it and press the button that says Calibrate . At that moment, we will have to give a single touch to the panel so that it begins to recalibrate it. And so on with the different options that it will tell us: two touches, long press for 2 seconds, slide left or right, among other options.

Also, so that you can get a good result, it is better that you put the smartphone on a flat table. Then, follow all the steps that the Google Play application will indicate. When each test is complete, if everything is OK, it will appear green and come out labeled ‘ Passed ‘. In the event that it does not work well, it will tell us. Finally, when all the calibrations are done, it will tell us to restart the device so that all the changes are applied.

built-in function

However, some early Android devices, up to Android 4.0 (Ice Cream Sandwich), had a built-in calibration option within the operating system itself. Depending on the device and software version, this tool could be found in Settings > Language & keyboard > Touch input > Text input. Then we should find the Finger Touch Accuracy > Calibration Tool or Reset Calibration option.

Can I increase your sensitivity?

In some customization layers, as is the case with One UI , we find that we can increase the touch sensitivity of the smartphone screen. However, it is not a feature that comes standard in pure Android. Within this Samsung software, we find the Touch Sensitivity function. Basically, what it achieves is that we can increase it for when we put a screen saver on and it doesn’t respond as well as it should.

An option that is very useful

Over the years, we have seen how at the hardware level , mobile screens are becoming more precise and, rarely, they begin to give touch problems. However, it is something that can happen at any time. Also, in most cases, when it starts to give errors, it will be because something is wrong with the hardware, and this is something that we ourselves will not be able to solve with a test or with any app, in those cases only we have to change the display of the smartphone.

But, that does not mean that we should not help ourselves with the calibration of the screen to rule out major problems . Therefore, in any case, it will help us to know if we are facing a specific error or it is due to something more serious. In addition, there are situations in which recalibrating it will be very useful, especially when we have placed a protector and the phone’s touch has begun to act differently.

Even, not only will it help us in these situations, but it will also allow us to readjust it so that we can have a better user experience at any time. For this reason, it never hurts to know how to calibrate the panel of a mobile.
