Hi there, As anyone seen this before? We have both the same Samsung Galaxy S 4G and recently when you go to your "messages", it will go back to the "home screen". Tapping on Messaging and then keeps going back to "home screen". Have to keep rebooting device but then it will do it again later in the day. Running Firmare Version: 2.3.6 Build Number: Gingerbread.VUVKJ6 Thanks in advance!
