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:

Nokia 5800 touch screen problem that is likely the latest v40 firmware bug.
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.

    my nokia 5800 is having a problem that when i touch or tap an item, it responds to an item on the right of it. Even touch screen calibration does not help, it gets corrected for few hours but then again return to the same problem. Further now the problem has become so persistent that it has now become virtually impossible even to calibrate the screen. when i approached service center they just upgraded the version but this didn’t permanently solve the problem and now they are demanding Rs 3000 for further treatment. Thanx in advance….

    Hi Saurabh.
    I’m having the same problem. Earlier I was having distorted display problem, so I updated my firmware to v51, but now this touchscreen problem is coming. If u find a solution, pls share.

    The calibration is more on software level.

    If calibration doesn’t work, then the problem is likely caused by touchscreen (the hardware) itself (as noted at top of this post). For faulty hardware, nothing can be done except replace the faulty part physically (Nokia certified service center is best bet).

    Hopes that help.
