Many people are looking for reasons and solutions to the problem of Samsung A12 touch screen not responding as they want to speed up their Android phones.

Why is my Samsung phone screen not responding to touch?

There are many reasons for this problem, including: The phone screen is dirty or wet, the operating system is outdated and needs to be updated, the touch sensitivity is very low, and one of the accessories connected to the mobile phone, such as headphones, is interfering with the screen.

High phone temperature, insufficient storage space, damaged phone, problems with touch screen calibration, if you notice that your mobile screen responds to touch operations that you did not perform.

If an application is opened without touching the screen, this is known as phantom touch, which may be due to problems with the hardware or software.

Solve the problem of the Samsung A12 touch screen not responding

If your phone's screen is experiencing any of the following problems: the screen is unresponsive, the screen brightness changes, the screen content is flickering, a screen flickers, black spots appear on the screen, or no content is displayed on the screen, try implementing the solutions below.

But before that, make sure that your screen is not broken, cracked, or damaged. If you are wearing gloves, remove them, remove them. If you are putting stickers on the screen or sensors, remove them.

1. Restart the phone

Turning the mobile off and then on fixes many temporary software problems that may be responsible for this. You can do this by pressing and holding the power button until the power options menu appears, then choosing Restart.

If you are unable to do this, force the phone to turn off by constantly pressing the power button and the volume down button at the same time until the phone turns off, then press the power button again to turn on your phone.

2 Clean the screen and screen

This problem may occur due to the accumulation of dirt and dust or problems with the screen or case, so try cleaning your phone well if the previous method does not work.

You can do this as follows: First clean your hands to avoid transferring dirt to the screen. Use a clean, dry cloth that does not have lint to wipe the screen.

You can slightly wet the cloth with alcohol and then squeeze it well, but avoid using water.

Sometimes the touch screen may malfunction if dirt accumulates and the side of the screen in contact with the screen becomes dirty, wet, or very hot. Then you will need to remove the screen and then clean it well along with the touch screen.

Note: If you remove the old phone screen that is many years old and has scratches, you will then need to clean the screen.

Also, the screen or the case may affect the touch sensitivity. You can verify this by removing both of them and then try using the mobile phone without them. If you notice that the screen works well, you may need to change both the screen and the case.

3. Dry the phone

If your phone is exposed or dropped in liquid such as water, this may cause the Samsung A12 touch screen to become unresponsive. In this case, you will need to dry it well, and the method is as follows:

Immediately remove the phone from the water and turn off the phone if it is on. Remove any removable components such as the battery and SIM card (if applicable).

After that, dry the phone with a dry towel, then place it and those components in a bag containing uncooked rice or silica gel granules for 24-48 hours. After that, I leave it in the open air until it dries completely.

4. Remove the SIM card

Sometimes the SIM card, SD card, and accessories connected to the device such as speakers, keyboard, OTG, chargers, game controllers, input and output devices may cause the Samsung a12 touch screen unresponsive problem.

Therefore, first turn off the phone and disconnect it from the power supply, then remove the mobile SIM card and the memory card from the mobile phone, as well as remove any accessory connected to your phone.

5. Turn on safe mode

It is possible that the issue is caused by an app you installed. You can confirm this by running Safe Mode which will disable any app downloaded on your phone except system apps.

Which prevents any application causing the problem from working, and therefore if you notice that the touch screen responds well in that mode, it is certain that the responsible for this problem is an application that you downloaded.

You can turn on this mode by constantly pressing the “Power button” until the “Power Options Menu” appears, then press and hold the “Power off” option until you see the Safe Mode icon, then click on it. You'll find Safe Mode at the bottom of the screen if that mode is turned on.

If the cause is one of the applications, the solution will be to remove all applications and updates that you have recently installed, especially those that you downloaded shortly before the problem occurred. After each removal, restart your phone and check if the problem is resolved.

6. Gently press the corners of the phone

If you encounter the problem of the Samsung A12 touch screen not responding after the phone falls on the ground, gently press each corner of the phone.

After that, test the touch screen to look for damaged parts of the screen. You can use the following codes: For Samsung Galaxy phones, dial the code #7353#* using the dial pad.

For Sony devices, dial *#*#SERVICE#*#* or *#*#7378423#*#*. For HTC mobiles, dial *#*#3424#*#*. For Motorola mobiles, enter #*0#*.

Once you request the code, you should be taken to the screen test interface. You can choose from different screen test options.

There are also many applications on the Play Store that you can use to test the mobile screen and diagnose the problem of the Samsung A12 touch screen not responding, such as Display Tester app.

When you open that application, click at the top of the screen on tests to display a list of tests. Each test is dedicated to diagnosing one of the screen problems, and next to each test you will find instructions on how to perform it.

For example, the “touch screen test” test can test the sensitivity of touch when pressed. It divides the screen into small squares, each square representing a pixel of the screen.

Move your finger on the screen until the color of the squares changes. If you find a square that has not changed color, that pixel may be burned and therefore it will not respond to touch. This test is useful to know whether there are damaged parts of the screen or not.

If the screen turns out to be working fine in touch-based tests, the problem might be with an app you recently installed so try removing apps you recently downloaded or performing a factory reset of the phone.

The screen may be working normally, but there is an application that affects its performance when used.

Google has stopped including this option in phones since it launched Android 4. Before that, users could usually access this option by going to Settings > Language & keyboard > Touch input > Text input.

Then under Finger Touch Accuracy, tap “Calibration Tool” or “Reset Calibration.”

If your phone is running Android 4 or higher it may not have a calibration option so you may need to download a screen calibration app such as Touchscreen Calibration app.

After the process is complete, a notification will appear informing you that the adjustment is complete, then restart the phone. You can repeat the screen calibration if you do not get a satisfactory result the first time.
