When I press the Home Key, it does two things. 1) The ringer volume displays for a few seconds and 2) it takes me to the recent app screen. I totally reset the phone today and it worked for a while, but went back to doing the same thing. I have the newest OS update from a few weeks ago. Also, when I'm on this screen none of the buttons will work. I have to press the power button to turn the phone off temporarily and then back on to go back to my home screen. Any thoughts are appreciated.
