I can't read through all the 55 pages of this thread now, so please forgive me if this was already asked (and yes i tried to search)...

For me sometimes, when i press the power button, instead of the qtlockscreen, the original lockscreen comes up, and everything freezes. The only way i can unlock the phone then is to open the keyboard (my unlock key on the side of the phone is broken, so maybe that would work as well, i don't know). Does anybody else have this happen? Is there an easy way to fix?

Thanks.
