Touch Screen not reacting or acting on its own
Please calibrate the Touch Screen. Choose the option "Touch Screen" in the Nintendo DSi options menu.
Please make sure you exactly tap the displayed calibration points (upper left corner, lower right corner, middle). If you have done this correctly a message "Calibration complete" will show up.
If you use a protective film on your Touch Screen please be aware that this can reduce the sensitivity of the Touch Screen. In addition, if the protective film is not attached properly, the Touch Screen can receive wrong control impulses, which can influence your ability to control.
In this case please remove the protective film and re-calibrate the Nintendo DSi as described above.
If this is not successful please send the Nintendo DSi to us for repair or replacement.
The exact cost of the repair can be found in the relevant repair price list, together with detailed information on the procedure for obtaining a repair.
