Android Smartphones Secret Codes To Test Your Touch Screen

Part 1: Why Testing Your Android Touch Screen Is Important?

The touch screen is one of the most important components of your Android smartphone or tablet. It allows you to interact with your device, launch apps, type messages, and play games. However, wear and tear over time can lead to various smartphone issues.

There are several reasons why you might need to test your Android touchscreen. For example, you might have noticed that your touch screen is unresponsive in certain areas or that it's registering touches you're not making. You might also check a phone before buying it to ensure the touch screen works properly.

Here are some common Android screen problems that you can test for:

Unresponsive Areas

Sometimes, specific areas of the touch screen may not respond to touch. Things like physical damage, dirt or debris on the screen, or software problems can cause it.

Ghost Touches

Ghost touches are phantom touches that register on the screen even when you are not touching it. Software problems and hardware issues may cause it.

Dead Pixels

Dead pixels are small dots on the screen that do not display any color or light. While technically a display issue, dead pixels can affect touch responsiveness.

If you're experiencing any of these problems, you can use a secret code to check your Android device's touch screen and identify the cause of the problem. In the next part of this article, you'll learn how to test your Android screen using them.

Part 2: Android Screen Test Codes

Now that you understand the importance of keeping your Android touch screens in good condition, it's time to go into the practical side. It's about test codes - simple enough to help assess and maintain your device's touchscreen condition. It includes dialing the following codes for checking the touch screen of smartphones:

LCD Test

The LCD test is a fundamental Android screen test code that examines the quality of your display. It checks for issues like dead pixels, color accuracy, and touch sensitivity. To run this test, simply enter *#*#0*#*#* or *#0*# into your phone's dialer. Once you've entered the code, press Call, and it will lead you through the process.

Touch Screen Test

The touch screen test will display a grid of dots on your screen. This one's a game-changer when assessing your phone screen's responsiveness. It usually involves dialing a combination like *#*#2664#*#* or a similar sequence.

Touch Screen Version Check

This secret test code helps you check your phone's screen's version number and compatibility. It's particularly useful if you're curious about your device's hardware or troubleshooting touch-related issues. To access it, you may need to enter a code like *#*#2663#*#*. Once you've entered this Android screen test code, follow the instructions on your screen to check the corresponding aspect of your screen.

These Android secret codes are simple to use and may not require any technical knowledge. But remember, results may vary depending on your phone's make and model. It's always a good idea to consult your device's user manual to find the exact code for checking the touch screen for your specific device.

While Android touchscreen test codes can be useful for identifying potential problems, they don't always provide a comprehensive diagnosis. That's where Dr. Fone's Phone verification feature comes in.

It can help you understand the overall health of your device, including its battery life, force reboot number of times, and jailbroken status. Using both tools together lets you get a complete picture of your device's condition and troubleshoot any potential problems more effectively.
