The touch screen of your Android smartphone no longer responds to the pressure of your finger? It seems to have become totally insensitive to touch? Don’t panic. We present you today different troubleshooting solutions to repair a faulty screen without having to resort to after-sales service.
What should I do when my touch screen no longer works?
Since the advent of all-touch, the touch screen has become the most important component of our smartphones. We use it all day long to enter messages, launch applications or simply play games.
And that’s the problem. Because the touch screen is more fragile than it looks. No brand, no device is immune to this type of failure. And when the touch function stops working, the whole smartphone becomes unusable. You can no longer do anything or even access your personal data.
First of all, it is important to know that a malfunction on the tactile part of a phone is not necessarily the result of a hardware failure. Most of the time, one or two manipulations are enough to restore a fully functional touch screen.
Cleaning your smartphone screen
Before using your phone, you must make sure that your hands and the screen of your phone are clean and dry. The touch part does not tolerate moisture (sweat) and grease. Indeed, the presence of dirt or liquid substance may affect the accuracy of the touch panel’s contact detection system.
For this reason, it is recommended that you thoroughly clean the display with a microfiber cloth. This will not damage the glass surface of your phone. However, take care never to use chemical products. Acetone, ammonia, or alcohol in some solutions will weaken the protective coating on the screens.
Also make sure your hands are clean. Last but not least, most phones do not work with gloves. So remember to remove them before using your smartphone. See also: how to repair a sleeping pixel.
Restart your phone
This advice is likely to make many readers smile. And yet, in many cases a simple reboot is enough to adjust the abnormal behavior of the touch screen of some smartphones.
Press and hold the power button on your device until the start menu appears.
Click on the Restart button
If the screen refuses to respond to your prompts, press and hold the on/off button for several seconds.
Wait a minute before pressing the power button again to restart it. If the touch screen still does not work after restarting the phone, you will need to proceed to the next step.
Before contacting the service department or starting the replacement of your mobile’s slab, we recommend that you launch Android Safe Mode. This will ensure that it is a software problem and not a hardware defect.
Safe mode is a kind of diagnostic mode for Android smartphones. It will temporarily disable all third-party applications installed on your device. Only essential Android components will be loaded at startup.
You will find in the link opposite the procedure to switch an Android device to safe mode. If the touch screen responds while the phone is in safe mode, you’ll need to find the application causing the problem.
