Anyone know how to disable it?? Every time I'm biking and receive a text, the phone wakes and all hell breaks loose in my pocket. I don't want any notification waking the phone and I'm going crazy trying to find how to disable it!
Try - open the app Mobile Manager, then tap Notifications. Look for an app named Messaging and disable it. It'll prompt a confirmation and then preferably select block all. You need not worry because you could change this back to your previous setting at any time by following the same procedure.
