![]() This is a problem which should arise only if you are using a third party charger with your Android device. ![]() If you are facing touchscreen problems only when your device is connected to a charger, you are not alone. You can check out our detailed article on how to boot your Android device in safe mode for more details. ![]() If you feel that poor touch responsiveness is a software issue you are facing due to a bad third party app, you should start-up your Android device in safe mode. When your Android device is running in the safe mode, only the system apps start running, which means that if you have a third party app that might be causing problems to the touchscreen, you will know. Generally, modern day smartphones pack in 5 to 10 multi-touch points and you can use a third party app like MultiTouch Tester to see if all the touch points are working properly. It can also be a hardware problem with the display’s digitizers not working properly. If you feel that your device’s touchscreen is working in patches, there might be a few issues with multi-touch. Moreover, it also shows you the touchscreen’s accuracy. While Android natively lets you correct color in Accessibility settings, it’s aimed at people with low vision and for experimental purposes only. So, if you want to calibrate the display, you can use a third party app like Touchscreen Calibration, which calibrates the tap, double tap, swipe gestures and pinch gestures in a simple yet radical process. Well, display calibration fixes both accuracy as well as color correction. Also, along with that, the display tends to get inaccurate after a while, resulting in wrong touches. Over time, a display tends to get more warmer or cooler and thus, needs to be color corrected. Simply head over to Settings->Display and turn off “ Ambient Display“. While this feature might be useful for devices which don’t feature a notification LED, you should try turning it off for a better touchscreen experience. Ambient Display is very much like the Moto Display feature, which brings you interactive important-only notifications in a Black & White format while the device is locked. While we don’t know the exact reason, Android’s Ambient Display feature that arrived with Lollipop seems to be causing some problems with touchscreen responsiveness. However, if you haven’t already, you will have to enable Developer Options first by going to Settings->About Phone and tapping on Build number 7 times. Enabling GPU 2D Rendering should render the user interface elements and transitions faster, making sure your touches are indeed registered.
