Experiencing a non-responsive touch screen can be incredibly frustrating, especially when you rely on your Android device for communication, work, and entertainment. In this guide, we explore the common causes behind the touch not working on Android issue, along with effective troubleshooting methods and preventive measures to ensure your device remains functional.
Understanding the Android Touch Screen Technology
Before diving into solutions, it’s helpful to understand the technology behind touch screens. Touch screens typically operate on one of two main technologies: resistive and capacitive.
Resistive Touch Screens
Resistive touch screens consist of multiple layers, with two conductive layers separated by a thin space. When pressure is applied to the screen, the layers touch, registering input. This technology is less sensitive than capacitive screens and can be operated using a stylus or finger.
Capacitive Touch Screens
Capacitive screens, on the other hand, use the electrical properties of the human body to detect touch. This results in a more responsive and finer interaction, which is why they are more commonly used in modern smartphones. However, they require direct contact with skin and may not work if there’s an obstruction, like a screen protector or moisture.
