Backspace is too sensitive :-(

My primary situation:

The keyboard is generally working fine but the backspace only needs a fine touch not a complete depress. That means that it will delete half a line in no time when touched. It is placed slightly lower than the rest of the keys but it still has the "click"-sound and -feeling like the rest of the keyboard.

I got the phone in dec. 2011 and it has been used moderately since then. I'm not a heavy text'er or anything like that.

My question (for a solution):

The SK17i tear down does not fully show the parts of the keyboard. Is there a rubber mat between the keyboards outer skin and the contacts?

Is the contruction similar to that of a remote control?

Will I need a whole new keyboard (it's danish)?

Answered! View the answer I have this problem too

Is this a good question?

Jesper if you are referring to the "domesheet", yes it does have one. You can replace the domesheet, but it sounds like you are needing a new keypad.

The keypad is on the back side of the main board. The domesheet lays over it.

What is the PCB shown at the bottom photo?

It could be difficult to find a danish keyboard... :-/


I attached an image to the original answer to show that it is the backside of your main board. I did a quick (very quick ;) search and only found a QWERTY keyboard on ebay. A danish one may require a bit more of a search.


Danish keyboards have QWERTY-layout too, but we have some extra letters (æøå)... :-)

So I will need a new main board?


A new keyboard should work and is probably easier (not meaning easy) than the board. You could try and disassemble it and take a look and see if you can isolate the problem.
