When I first got my Droid 3 a few months ago, the swipe/lock screen was functioning the way it's supposed to (I believe). When I would press the unlock button on top of the device and the screen would come on, I'd swipe my finger across the screen, as noted, to unlock it. Now, for the past few weeks, whenever I click the button up top, either the "swipe screen" appears for a second and then disappears by itself, without me swiping - unlocking the phone by itself, OR (more often) the swipe screen never appears in the first place and the screen just comes on, right onto the home. I have not, to my knowledge, installed any app to work around the lock screen nor is my phone rooted. When I setup to use a pass code or unlock pattern, they both work as expected, but the plain, default, no-code and no-pattern unlock swipe just doesn't function. I'd like to have it back. Ideas?
