My Android HTC Sense 3.5 running Android 2.3.5 suddenly and out of the blue activates the unlock screen without pressing the power button. That's a problem because it gets unlocked by itself sometimes when it is in my pocket. Is there a special setting to disable this activation of the unlock screen?
I don't know why this happens, but you may be able to combat the problem with Proximity AutoLock. If the phone's screen is somehow turned on, the proximity sensor should tell the phone to turn its screen off right away. Now, this works when the power button gets pressed; I would think it would also work when other events turn the screen on, but I'm not completely sure.
You can set up a screen lock that requires more that a keystroke to unlock the phone, as to prevent the phone being unlocked when bouncing around inside your pockets:
- Click your phone "menu" button;
- Tap "Settings";
- Tap "Location & security";
- Scroll your way to "Screen unlock" and tap over "Set up screen lock";
- Pick your poison, for me it was "Pattern";
After selecting a more robust method to unlock your screen, even if the unlock screen pops up while the phone is in your pocket, it will be virtually impossible unlock the phone that way.
