Is there a way I can set my phone to only pull up the lock screen on pressing the side button? I can feel my phone vibrating as it is pressing the touch screen in my pocket. A little while ago, i actually managed to call 911 with the phone in my pocket. It just pulls up the unlock screen, opens the "dial emergency number" option, and one-presses to call 911. I had to explain to the dispatcher that my phone called them on accident. This seems like a serious design flaw. How do I fix this?
