Jailbroken, 4.3.1 untethered. Anytime I get a text message (sms or mms) and the phone is locked, it unlocks and the little preview screen comes up showing I have a msg from so and so...HOWEVER, the screen will stay lit up, and the phone will not lock unless I lock it. Ofcourse, if I'm not near my phone, this is a HUGE battery drain. Is there a setting somewhere I am missing? I have played with multiple configurations, and nothing has helped. Thank you for your time.
What do you have under - Settings -> General -> Auto-Lock What JB apps have you installed? It could even be something seemingly unrelated
Tell me your Cydia apps. I recently had this issue, removed something from Cyia, and it started working again.
I found the culprit. It was in app called LOCKINFO. There was a setting that says "Wake Upon Alert", and I took that off, and the problem is solved. Thanks anyways.
