Android

• 1). Press the "Home" button or capacitive area, then press "Menu." Tap "Settings."
  
  
• 2). Tap "Language and keyboard." Tap "Keyboard settings." Tap "Tutorial" and go through the steps that appear on your screen.
  
  
• 3). Once this is finished, turn your phone off and on again. Your keyboard has been adjusted, which activates a re-calibration of the capacitive touchscreen. (Capacitive screens are technically far more accurate that resistive, and so a full calibration tool is not included with Android phones.)
