Issues With Android Touch Screensby Steve Brachmann
Smartphones and devices running Google's Android software are often also optimized for touch-screen operation, which Android's software supports. Issues in touch-screen operation on Android phones can seriously hamper a user's ability to access necessary applications or even complete basic tasks in advanced cases. App developers must also adjust program code to accommodate touch-screen usage.
App developers who create programs for Android smartphones have to develop programming code, which accommodates the touch screen utilized by most Android phones. Compared with keypads, a touch screen navigates with a much looser focus. Where a keypad scrolls through definite options, a touch-screen user can tap the screen in areas that aren't clearly defined by a program, and a developer needs to plan for this. Instead of coding the app for selected item position, which can fit poorly with the unfocused touch mode of Android phones, developers should use click listener and choice mode code.
Touch screens on Android phones can sometimes become uncalibrated, especially if you've just flashed a new operating system to your smart phone or other Android-powered device. Many Android devices have a pre-installed calibration app found in the applications menu or in the device's settings. Calibration apps designed for specific models of Android tablets and phones are sometimes available in the Android app market.
Another commonly reported problem associated with smartphone touch screens is sensitivity. Oversensitivity and reduced sensitivity of the touch screen can have major effects on the functionality of a user's Android phone or device. Symptoms of touch-screen sensitivity problems include devices registering a finger swipe as a click or an inability to register any finger click to make a selection. Protective screen films can sometimes cause reduced sensitivity problems. Restarting your Android phone or device can take care of some sensitivity issues.
Many Android touch-screen issues are specific to the manufacturer of the smartphone or device. For example, Motorola produces Android touch-screen phones, which require skin contact to register a click or a swipe, while some HTC phones will exhibit symptoms of oversensitivity. Android phone users should contact the manufacturer's customer service department if they begin experiencing issues with their touch screens.
