Since day 1 I have been having this issue. My droid 2 will do a screen lock when the direct sunlight hits it. This leaves me unable to use my phone in the sunlight. The problem is not that it is too dim to see in the light, it is the fact that the screen actually does the "time out" like it would normally (I have mine set to time out after 30 seconds, but it does it immediately after the bright light hits it). I have only experienced this outdoors. Not one issue inside. I have tried turning my brightness up before I go outdoors, but that did not help. I don't know what the problem is.....any help would be appreciated.
