The Nokia N97 has a touch screen and keyboard interface.
The Nokia N97 smartphone has two methods of interacting with the phone: the touch screen and the built-in keyboard. A majority of the phone's navigation is done with the touch screen. If the touch screen is not working, you can't use many of the phone's features. Troubleshooting the Nokia N97 touch screen can return it to normal operation.
Types of Problems
The Nokia N97 touch screen can stop working in two ways. The first is the screen is frozen, meaning it does not respond when you tap the touch screen. A frozen touch screen is often the result of an error with the phone's software. The external buttons may still operate the phone when the touch screen is inoperable. The second type of problem with the touch screen is that it does not respond to where you are touching the screen. For example, you tap one menu item and a different item on the list is chosen. This is a screen calibration issue.
Frozen Screen Solution
Repairing a frozen touch screen on the Nokia N97 requires you to restart your phone. If the side buttons are working, turn off the phone using the "Power" button. This is the standard, and easier, method of shutting down the phone. If the side buttons aren't working, remove the battery from the back of the phone to force the phone off, and then reinstall the battery. Once the phone is off, press the "Power" button to turn it back on. The touch screen functionality should return to the phone.
Calibration Solutions
Nokia designed the N97 with a touch-screen calibration program to remedy problems with the touch screen. Opening the touch-screen calibration program requires you to use the touch screen, which can prove difficult. You're forced to judge where to tap the screen because the screen isn't recording the precise location of your taps. To find the touch-screen calibration program, open the main menu, select "Settings" and then "Touch Input." The program provides on-screen instructions to help you finish calibrating the screen.
Repeated Problems
Troubleshooting the Nokia N97 when the touch screen isn't working may only fix the problem for a short time. When the touch screen regularly stops working, take note of the programs you are using when the problem occurs. If you notice that one program causes the problem with the touch screen, remove the program from the phone. In the event you can't pinpoint which program or action is causing the problem, you can perform a hard reset to return the phone to its factory settings, which is how the phone came out of the box. A hard reset deletes all of your data, settings and any programs that you installed on the phone. To perform a hard reset, turn off the phone. Press and hold the left "Shift" button, "Space," "Backspace" and "Power" until the phone starts up. If the hard reset doesn't solve the problem, visit your service provider.
