Hello all, if you (like me) have a Samsung SGH-i600 (or blackjack in America) and have noticed dust entering the unit and collecting in the top left hand corner of the screen - I think I have a fix for you.

The i600 comes apart reasonably easily. You've got two screws under the little rubber bungs at the top, and then four more underneath the battery cover.
Remove the battery, and sim, and then work a small plastic shim (I use guitar plectrums) around the join between the two halves.
There are two clips on the top of the unit that keep the two haves together.
**When you're doing this, remember there is a ribbon cable running from the camera/speaker unit on the back to the motherboard. Be careful, and just lift the connector up and away from the motherboard as you lift the back. Be careful to not lose the power, camera, and up/down buttons which are now loose.
Once you've done that, inspect the motherboard. Here's a closeup. In the red circle is the power button, and a screw hole. Now, that screwhole wasn't one you've just removed a screw from...
If you have a screw in this hole, then my fix does not apply to you. Replace that ribbon cable by gently pushing the connector back, ensure your buttons are back, and put your phone back together.

Awesome, thanks for the great post. It encouraged me to dive in and fix the same problem on my phone! Couple of notes... First, why do you tell people to stop of they have those screws? I keep going even though I had those screws, and everything worked out fine. Second, I suspect that the dust came in through the scroll wheel. There was a LOT of dust around the wheel when I took it apart. When I put it back together after cleaning, I added some silcon gasket filler in the small gap that exists between the wheel, the plastic body, and the circuit board. I was afraid that ticky tack would melt and run into the circuit board. Thanks for your help!
