Mine just started earlier this week. Slowly since the new update but really picked up this week. Especially text messages. When I receive a text and click on the message icon, it will bring me to a totally different text. Sometimes it takes me clicking on it 5 times or so before it brings me to the correct message thread from the person who just sent the text. Same when I try and text someone, click on that person's thread, it takes me to someone totally different and not even close to where that person is located. I'm using the stock messaging by the way. And now sometimes the browser will just shut off and go the home screen randomly. And it sometimes takes 5 presses to open an icon. Just weird little things that never seemed to happen before. And it seems to lag more lately than it used to. A reset usually does the trick so it is not a major issue but still.
