Has anyone else had issues with trying to answer the phone when someone calls. I was sitting at my work desk with phone on vibrate, I get a call. Starts vibrating and the screen is still black. I try to wake up the phone by pressing the power button on the top, screen flashes on then turns off. I'm about 4 rings in at this point. Caller ID shows who it is and the slider appears, I go to slide it over and it freezes for a second. Go to slide it again and finally answers the call. It took me about 10 rings to answer a damn phone call when I had it sitting right next to me on the desk. This is quite ridiculous!
