I have a similar problem to the one posted in this other thread. The difference is that my phone stays locked when it turns on. So the "solution" posted in the other thread won't help me since it has nothing to do with forgetting to change my options before locking and throwing it in my pocket. My issue is not that buttons are pressed and settings changed, but that my back-light stays on and drains my battery faster. Some details: Using FROYO 2.2 Motorola Droid. Waking my phone with the power/lock button works as expected (after ~5 seconds sleeps). Opening slider makes the back-light stay on (even after closing it). Does this happen to anyone else? Open then close slider, does your backlight stay on? Is there a setting that modifies this behavior?
