[Galaxy S II General] CRXed:
I just did a complete Factory Reset, just to test this and to see if I am crazy not......

On a complete fresh installation, you can unlock your phone on any position on the ring. The unlock icon is only shown on the right though.

But I have no problem unlocking my phone in any position, top, left, bottom, right.

Seems like it crashes when there is no connection to the Google services at startup....

Going to clear the data of the app now to see if it helps.

EDIT: No, clearing the data did not help :(

Removing YouTube app and reinstalling it now....

EDIT 2: Reinstall seems to have fixed it.
