How to test the smartphone display? | Instructions

Like all electronic devices, smartphones go bad over time. The most vulnerable part of these handheld “computers” is their display. Whether you own an older device or purchased a new one a few months ago, there are several apps available in the Google Play store to help you test your smartphone display. We bring you a selection of the best in today’s article, through the Gadgets To Use portal.

Screen Test

The Screen Test application simply tells you which display pixels are no longer functional. The application contains several monochrome backgrounds and gradient backgrounds, which you can switch between by touching. If the background is displayed without any random dots or parts that distort them, it means that the display is OK.

Touch Screen Test

With the Touch Screen Test application, you can test the touch sensitivity or whether your smartphone can register multiple touches at once. Like the previous application, this one works very easily. All you have to do is draw lines on a contrasting background. When you come across a section where the drawn line does not appear, or you have to press more to make it appear, it indicates a problem with the area.

Android Testing Tool

If you plan to test even more than just the display, then an application called Android Testing Tool is for you. In addition to testing the functionality of the touch and support for multiple touches at once, the application also offers, for example, the ability to check the microphone, Wi-Fi connection, NFC functionality. It also shows you information about your device’s hardware and its current usage.

Display Tester

Lastly, we have the Display Tester application, which offers several tests, including more advanced ones. It will help you test, for example, color, contrast, angle of view, multi-touch support, or help you find dead pixels.
