Yeah, a software error makes most sense to me. So, what app do we all have in common that is causing this issue?
I can make that an easy answer, since I just got my phone I only have put two apps on it, task killer and missed call...... see if you guys have any of those two.
I never had task killer installed and never had missed call and it happened to me, so that's not it. The app I did installed the night before it happened, was a unit conversion app from the store (which I can't remember the name off, as I uninstalled it very quickly)
And BTW, if I want to call my phone a brick, I think I can still do so!
