Whenever I unlock my phone, it goes crazy. It starts having a spazz attack and clicks on random stuff by itself. For example, I will go to my messages to try to text someone and it will just start clicking on letters and buttons out of no wheres, causing me take 20 minutes just to send a simple message. I have no control over it and it is really annoying. This started happening after I went in the store to get my cracked screen replaced.
