Fix Nokia 5800 v40 Touchscreen Issue
Here are two potential fixes to resolve Nokia 5800 touchscreen problem. I have to repeat again, that these fixes do not guarantee fit your case, especially if the touchscreen is broken or faulty.
Touchscreen calibration: When the touchscreen is not response exactly on the point of touch or tap by finger or stylus, then this is likely a touchscreen calibration issue.
If not mistaken, the Nokia 5800 technical specs states that this smartphone is using the resistive touchscreen type. Over the time, the resistive touchscreen might not response correctly to the point of touch or tap. To fix this software issue, you need to perform an easy tweak called touchscreen calibration.
To calibrate Nokia 5800 touchscreen: Click the menu key > Settings > Phone > Touch Input > Touch screen calibration. There you are prompted to tap centre of target with stylus, where the 4 circles (target) at the corner animates one by one to guide user complete the touch screen calibration process.
Potential v40.0.005 firmware bug: I am not sure this “bug” or scenario happened in earlier Nokia device software version.
During the first encounter, I thought the touchscreen hang. At second glance, however, I realized the touchscreen locked but the display light lit on as if it was unlock and active for input:
There is an icon of key appears next to the time display, indicates the touchscreen and keys are locked.
This is different experience to me. As to what I recall, the Nokia 5800 touchscreen backlight is dim and a message alerts user to use keyguard switch, when tapping the locked touchscreen.
How to fix this? Well, you can only pay attention to the little key appears on screen – if this icon appears on the top end of display, then just use the keyguard switch to unlock the touchscreen before continue touching or tapping the locked touchscreen.
