I just got the Note 3 yesterday. My lock screen will light up whenever I receive a text message. It did not do this at first, but now it does. I went through my apps and can not seem to find one that would cause this. I've been through the settings several times trying to figure out what I did to do this. I now have it in blocked mode blocking all notifications and that helps. I'd rather not have to keep that mode on, but I will if I have no other choice. I appreciate any help I can get. thank you!
