It mainly happens when I'm in the messaging and I'm trying to text, after I hit a couple letters, it will freeze on one letter, and then shut the keyboard down, and even if I hit the where to type, it won't reopen, I have to leave it alone for about 10 seconds then it will reopen on it's own. It started doing this a couple days ago.. I haven't downloaded anything or had any upgrades to my phone, so I'm really at a loss here.. any help will be much appreciated!
