My original Bionic did it three times: The phone goes into "sleep" or off or whatever that mode is when you're not using it. When I hit the upper button, nothing would happen. The email blinker was blinking. The phone was "on", it just wouldn't wake up. Pulling the battery fixed it. I was within 14 days so I went to Verizon, they reported no such issues, so I swapped for a new one. Today (2 weeks later), for the first time it happened again, on my NEW Bionic (plus new SD card, plus new extended battery). This time I went to Verizon with my phone so they could see the problem. They logged it. And just now, it happened AGAIN, at home. So I tried something different: I called my Bionic. No answer. So the phone is on, it just won't wake, and the actual phone won't answer. This had better be software that can be fixed! Other than that, LOVE my Bionic!
