Internals of the MPX200

after a lot of playing and experimenting to find a solution about the

DownLeft diagonal problem I though you would all like to see what the

internals of the MPX look like.

These pictures are only of the main keyboard housing at the moment but

in the near future I may do more of the display as well.

Word of caution do not try this at home unless you have the correct tools and want to void your warranty.

d/l worked u/r never

Interesting, that's the first time I've seen anyone mention that.

I will have another look later and may reposition the D pad and technically it would only need to be out of alignment by microns to

stop working correctly but I'm still looking into other possible causes.

OK play with silicone time it is then :D

Now depending on the quality of sealant they used I'll have to be carefull not to split

the membrane :)

Ok an update for you

The fault is not a definate hardware or software problem but with the help of beersoft I have tested the inputs for the key presses as well and found sone interesting results.

1, If you press and hold the Action button only the UP and Right directions work the

Down and Left refuse to register at all.

2, When the other directional buttons are pressed both Left and Up (for example) are registered, but if you press the DownLeft only one of the commands are registered.

3, The Action button only registers when it is released and not when it is actually pressed.

Unless I can get hold of a broken phone to dig deeper finding a solution may take a bit longer :?

Er u sure about number 3?

Go to type a new message and press and hold the action key in the subject field. You'll hear that it's registering over and over!

im currently working on a better key tester app, the example one i modifed out of the sdk samples seems to do some random things from time to time.

Im going to keep working on this and fingers crossed i will get the same results on my e100 and mpx

later

It does seem to depend on the command being called for

It's kinda like that on a PC, innit. If you click on say for example Close, and change your mind, you can hold down the mouse button and move off. It does register that you've clicked, and changes the button on the screen, but doesn't actually apply the function of the button until you release the click over the button.

The hardware in the phone must be telling the phone what is going on, but it's a decision by Microsoft to do what they do on desktops. Imho, it's better that way, as I suppose you could press Back or something if you pressed the action button by mistake before releasing it.

Not sure if any of that makes any sense, but there we go.

Sounds to me to be more like a software fault.

Its probably a fault when handling an input like:

ACTION_DOWN

ACTION_UP

Or something like that - like using Mouse_over, mouse_down etc when programming.
