A touch screen is an electronic visual display that can detect the presence and location of a touch within the display area. Touch screens can sense both intentional and unintentional touches. Most touch screens use either capacitive sensing or resistive sensing technology. Capacitive sensing touch screens detect the electrical capacitance of a human finger, while resistive sensing touch screens detect the change in resistance between two conductive layers.
Android tablets are popular mobile devices that are often used for gaming, watching videos, and browsing the internet. However, like all electronic devices, Android tablets can sometimes experience problems, including touch screen issues. If your Android tablet’s touch screen is not working properly, there are a few things you can do to try to fix the problem.
Here are some tips on how to fix an Android tablet touch screen that is not working:
- Restart your tablet. This may seem like a simple solution, but it can often fix minor software glitches that can cause the touch screen to stop working.
