no text notification on lock screen
I have just recieved a couple of text messages but when my phone is locked it won't notify me. The only way i know if i have recieved a text is if i unlock the phone and i will then see a number above the message icon relating to how many texts i have. Does anyone else have this problem? It doesn't do it all the time just from time to time. My battery is below 20% im not sure if that has anything to do with it. I have iPhone 4s running IOS 6.0.1
