HOW THE TOUCH SCREEN CALIBRATE YOUR ANDROID
A perfect solution if the touch pad smartphone to learn why stops working properly
When electronics are involved, the products of companies are not immune to manufacturing defects, whether revealed almost instantly when they reach the hands of consumers or many months later. One of the most complicated components of a smartphone is its screen, especially in cheaper phones, because it is what allows us to communicate with the terminal.
If the screen of your smartphone or tablet is marketed as multi-touch 5 or 10 pressure points, how can you be able to know that all areas of the screen are equally sensitive? Is there any part that is not necessary to press both your finger (or vice versa)? If you want to know the answers to the above questions it is clear and the solution to problems that may arise from these, it easily allows you Android with one of the lesser known features of the operating system, developer mode.
The first step is to enable the developer options on the menu of the device. To do this we go to Settings -> About phone -> and press 7 times in the Build number. After that we will receive a message that indicates that we are now developers, allowing us to access a hidden menu.
The second step is to go to these options developer and search “Pointer location” and “Show pulsations”. Both functions must enable and verify how a top bar appears with values that may be a little strange and a gray circles under your finger every time you press the screen.
The third step is to see whether or not the touch screen works properly, something we can do thanks to the top bar that has appeared. The value of the left (P: 0/1 by default) indicates how many points of the screen is reading at that time. In case your device has a multitouch 10 points, placing our 10 fingers on the screen, it will automatically appear X / 10 in that value. Of course, if the X value equals 10, everything works perfectly. If this does not happen, it would be best to go to the manufacturer or vendor to change the component, although it should be noted that the failure may also be due to a software problem.
As a check, the fourth step is to try to bring our fingers to areas that assume not work as well as the rest. If we push harder a red line also longer in the top red bar appears on the screen, indicating that this area is likely to be affected by any problems.
