No, that doesn't work, at least not on my freshly updated I747M with JB 4.3... all that does is remove the actual preview of the message from the banner that shows up in the right-hand pane of the lock screen. So instead of the banner that has the text message in it, now I have the exact same banner that just says "New Message" in it.
I would just like to get rid of this completely so that Dashclock can work as intended and show the notification, not the fugly samsung screen.
Cheers
EDIT: Just noticed that if I turn off notifications in the samsung sms app completely, then infact Dashclock does still see the notification and display it, but now I lose my vibrate and ringtone. I guess what I want is Dashclock to work, but also have the vibe/tone but NO samsung preview or lockscreen interaction. Anyone know if that can be accomplished?
