Default [Q] Z1 doesn't vibrate when receiving sms on vibrate mode.

Hi guys, after updating to 4.4.2 my Z1 doesn't vibrate when receiving sms when on vibrate mode. Then I thought it was just a bug on the current ROM. Then when I updated today to 4.4.4, it still doesn't vibrate. Do you encounter this problem?? It will vibrate if I manually set it to vibrate when receiving new messages. But if I keep that on then return to NOT VIBRATE MODE (sound mode), it will still vibrate. It doesn't do this before 4.4.2.
Just press the THANKS BUTTON because I'm a thanks button whore. LOL

Came from SGA, now with the monstrous Z1.
