Oh dear, after waiting a month for my 9900 I think I have received a duff one. It was fine for the first day (yesterday!) but today the screen lock button does not turn off the screen, and if I just leave the 9900 lying on a table the screen stays on.
I haven't loaded many apps, but I did load Google Sync most recently so maybe that is the problem?
Im having the same problem! I thought I fixed it when I pulled the battery out. It works for awhile but the problem comes up almost every other day. Gonna take mine in I think...
