Touchscreen calibration on Android devices refers to the process of adjusting the sensitivity and accuracy of the touch input. It ensures that the device registers touch commands precisely at the intended location on the screen. For instance, if a user touches an icon on the display, proper calibration guarantees the application associated with that icon will launch correctly.
Correct calibration provides an enhanced user experience, preventing unintended actions and improving overall efficiency when interacting with the device. Historically, calibration was a more frequent requirement due to the limitations of early touchscreen technology. While modern capacitive screens are generally more accurate, deviations can still occur due to software glitches, physical damage, or manufacturer defects.
