Home Buttong / task manager opening
So, I have searched all over the net including here and I have not been unable to find an answer to my problem. After I updated to 4.3 for some reason now, whenever I press Home Button it automatically brings up the Task Manager, something it never did before. I have read this has being happening to a lot of people but I am just wondering if there is a fix for it. Now, my button press has not change from before, a simple tap on it. So its not like I am holding it down or anything.
Does anyone have a solution? I am not rooted, especially since I read that My Account now reads any rooted phone, so I am kinda worry that I will lose any warranty after they tag you.
