I just got my S6 edge about 2 weeks ago, I've noticed I had a problem using the top left corner of my touch screen, when I'm in my text messages, I press the arrow to go back and it doesn't recognize that I'm even touching the phone. I have to use the back button at the bottom of my phone next to the home button. Is this an issue with anyone else? The only way I've been able to fix it is by restarting my phone.:'(
