Modern smartphones, tablets and PCs with touch screen use indium tin oxide (ITO) glasses, and these glasses are highly durable. So the chances of natural degradation in responsiveness of the touch screen over time is not very likely, unless you use it very rough. If your touch screen is unresponsive, there can be a hardware fault or software issue. Hardware issues are sorted at service centers (they replace your screen if your warrantee period is not over and it is not your fault behind your screen�s unresponsiveness/ damage). If your warranty period is not over, visiting service center for a screen replacment is the most recommended thing to do. It takes time for the replacement, but it is worth it. In case of hardware issue you can not do much by yourself, but luckily most of the times touch screen sensitivity issues are software related or result of some bad handling, which are fixable using easy tricks and tweaks.
Before we go to the tricks and tweaks section, let�s get aware of some of the preventive measures to keep the device�s touch screen last long and work smooth.
Do Not Keep Your Phone in Your Pocket
Do not place your phone in the rear pocket of your tight jeans. Also make sure you do not have coins, keys or any other pointed type of object in the same pocket with your phone. Too much pressure (when you attempt to sit), and scratches can negatively affect the sensitivity of your device�s touch screen.
Too Hot and Humid Condition
Hot and humid condition can make your hands sweaty and sweaty fingertips keep you from experiencing smooth swiping or sliding on your device. Sweaty tips make it hard for the touch screen to distinguishing what is a finger, and what is sweat. That confusion makes the screen go unresponsive. Although it does not cause any lasting damage, it temporarily spoils your experience with your smart device, and it can make you think that your touchscreen has got some issues.
Use Screen Protector
Every smart device owner should consider purchasing a screen protector. Screen protectors are made to repels skin oils, sweat, and dirt. An uncleaned screen can give you rough and unresponsive experience. And last but not the least, screen protectors keep your screen from getting scratched. Select the right kind of screen protector that not only keep your screen safe from scratches, but also not affect the sensitivity of the touch screen. Too thick touch screen protectors can cause insensitiveness.
Use Microfibre Cloths
Make it a habit of cleaning the screen using a microfibre cloth. It will keep your screen from dirt built-ups. Microfibre cloths are soft and made of very small and microscopic thin fibres that suck up dirt and oil without causing any kind of scratch or harm to the screen.
Touch Screen Troubleshoot (Software Related)
Most of the touch screen unresponsive issues are software related and can be fixed with ease.
Reboot refreshes everything in a device. From operating system to apps, to Wifi and other connectivities, everything. And in many case only a reboot can clear up many issues.
Eject SD Card, SIM and Battery
If reboot did not work, try this method which is a little bit maximum. Turn off your device, eject your SD card, SIM (or SIMs), and battery. Keep it like that for 1 minute. And then Insert SD card, SIM and the battery, and turn your device on. This method can fix a whole lot of software related issues.
Touchscreen Unresponsiveness Due To Bad Apps
Do you remember when did you first experience touch screen unresponsiveness? Did you install any app before that? Maybe that app is the culprit. Delete all data of that app and uninstall it, and see if that fixes your problem. Some app installation (or even updates) can invite malware into your phone or tablet. Malwares are capable of corrupting phone�s device drivers which can results into touch screen problems. Malware can cause unresponsive, exaggerated or in some cases complete loss of sensitivity. Normally, uninstalling such malicious apps from your device can fix your problem. If not, try the next method, which is kind of extreme.
Fix The Problem Using Touchscreen Calibration
Calibration tool is useful when your touch screen responds slowly or detect your touches inaccurately. There are some good calibration apps available in the Google Play store for free. You can try any of those based on ratings and reviews. Success using this method is totally depends on the app, so this is not a recommended option to get rid of the unresponsive touch screen issue.
Factory Reset To Get Back Touch Screen Sensitivity
Factory reset or master reset is all about going back to the original manufacturer settings. In this process all the data, information and settings are erased (including malwares, viruses and malfunctioning apps) from the phone or tablet. When no other method works, this is the ultimate weapon to fix any kind of software related issue.
Factory Reset From Hardware:
If your touchscreen sensitivity is completely gone and you can not operate it, there is an option for Android users to factory reset the device from hardware. But before follow the method, make sure your phone or tablet has at least 50% battery left. If not, first charge your battery and then act according to the following method to factory reset. The method may vary with devices but in general try the following instruction:
- Power off your android device.
- From power off state, hold the VOLUME DOWN key, then press and hold the POWER button until the boot menu appears.
- Use VOLUME DOWN to scroll to FACTORY RESET and press the POWER button to select.
- And the FACTORY RESET process will start after rebooting automatically.
There are few other grounds that may cause your device screen go unresponsive, like if you drop your phone on a hard surface, or in water (or any liquid), etc. So careful while handling your phone or tablet, and take some precautionary measures to make your device last longer. There are some myths related to touch screen unresponsiveness. For example keeping your device close to magnetic materials can cause temporary or permanent damage to the touch screen. That is not true. At least not yet proved. And finally use of stylus does not cause unresponsiveness of your touch screen.
