Since the system update I have to unlock my phone to see if I have a new text or email..the green light flashes, but I don't always know which it is I have. I used to have a little envelope appear when I'm turn the screen on and it still was locked. Now, nothing telling me about a new text. Also, I cannot seem to change from having the lock screen secured with a pattern to the simple swipe. Any suggestions how to change these things, if I even can anymore.
