Many of you mention removing the battery, doing a reset, D/Ling f/w, etc. And I have done all of those as well and it worked for me on a few occasions. But lately I've left the d**n thing alone. At random times I pick it up only to realize it started working again. But then it works for a day or two and the screen stops responding.

I had my hopes high when I read the success stories with cleaning the contacts. But I can't start explaining in my case how dirty contacts could cause problems for days and all of a sudden start working OK.

And why is it that a screen tap always lights up the screen, as mentioned by many posters?

Oh mystery...
