Ways to repair the screen of your Android mobile
Once you have identified a problem with your Android screen, there are several options for repairing it, depending on the severity of the damage and your technical skills. To start, keep in mind that some minor screen issues, such as unresponsiveness in specific areas or small touch errors, can be fixed by apps that recalibrate touch sensors.
Open the Settings app and go to the “About Phone” menu. Next, click several times on “Build number”. This will activate Developer Options. Once enabled, access them.
Within the Developer Options, locate the “Pointer Location” feature and activate its switch. When you do this, horizontal and vertical lines will appear that will follow your movements on the screen every time you touch the touch with your finger. This allows you to accurately verify all points on the display. If you notice interruptions in the lines, you will be able to clearly identify if there are faults in the panel and locate the exact problem.
If you're comfortable working with electronic devices, you can try to repair the screen yourself using a home repair kit. You can find kits for all types of mobile phones online.
Or if not, you can also directly buy the screen on eBay and other platforms and assemble it yourself. As you can imagine, you need to have enough knowledge and material to be able to carry out this screen repair. So, if you do not have knowledge, it is better not to try to repair the mobile screen because it could end up with permanent damage.
Plus, you have an app at your fingertips. We are talking about Touch Screen Calibration, an app that you can install on your Android phone and that will help you repair the screen.
Some of the Common symptoms that indicate something is not working properly include "ghost touches," when touch actions are executed without having touched the screen, or when the device registers more touches than we actually do. There may also be delays in the tactile response or even some actions may not be executed.
Once you have installed the app on your device, the process is quite simple. You just have to open the app and press the button that says "Calibrate." Then, follow the instructions it will give you: initially, you will have to touch the screen once to start the calibration. Later, you will be asked for more actions such as two taps, a 2-second long press, or swipe sideways, among others.
For best results, place your smartphone on a flat surface, such as a table, and follow the steps provided by the app. Upon completing each test, if everything is OK, you will see a green sign labeled “Passed.” If something is not working correctly, the app will tell you. Once all calibrations are complete, you will be asked to restart the device to apply the changes made.
