My wife's Eris will frequently not allow her to open the lock page. It's like the screen becomes totally unresponsive. There is no lock-out pattern stored, it's all stock. If someone calls we can use the hard answer button but can't answer a call on the touch screen from the lock screen. The only way to fix it is to pull the battery and restart it. But this seems to be temporary since the problem comes back every few days, but not all the time. The "experts" at verizon told her just to keep pulling the battery every time this happens. My question to you all is....WTF? Is there another way to open the lock screen? Like with the trackball or something? This sucks.
