    Hi all,

    I was on the phone and after the other person hung up, my droid was stuck on a black screen. The 4 buttons on the bottom would light up at times but still a black screen. I had to do a battery pull (read i wasn't supposed to on this phone?) and I still had a black screen. So I had to do another battery pull and it finally came back. Anyone else having this problem?

    never heard of such a problem. I haven't had anything like that happen to me yet. Even more interesting, you had to do 2 battery pulls...

    I've had the screen go blank on me after a call also. I tried pushing the power button nothing happened, the screen stayed black. I eventually had to do a battery pull after waiting several minutes for the screen to come back on. Its only happened once and I'm hoping it won't happen again

    hmmm

    By any chance do u still have a piece of plastic on the screen or maybe its dirty? I kept the plastic it came wit on it for a while until it peeled off on its own but i noticed when i made calls the plastic interfered wit the censor and after removing it didmt have that issue anymore

    It has happened to me quite a few times, but hitting the power button usually wakes the screen back up.

    Not that I should have to do this, but that has been my experience thus far.

    My screen goes black after a call goes through, as though I'm putting it up to my ear, when the phone is outside in bright daylight. I can't put in a password or even end the call. Only way to bring the screen back is to slide open the keyboard. As an experiment, I've shined a bright flashlight on the light sensor in the top left corner of several Droids. The screens went black on all of them but I not if they go blank outside like mine. I'm not sure what to do about this. Anybody else had this problem?

    Hey we're working on this problem here too.

    I wrote down everything I've figured out so far. Jump over and let's figure this out.

    Yes- I had the same problem. Sliding open the keyboard worked for me and brought the phone out of the sleep mode. Hope that works for you.

    Hey I was just talking to some people on a motorola forum. One of the guys figured out a good way to diagnose it. Download a free app called "Sensor Test," which gives you info about the accelerometer, light sensor, proximity sensor etc.

    From the other forum: "In the App under "Proximity" It should show "2.14...." when nothing is being detected at the proximity sensor and "3.0' when there is. If you put your finger over the upper left corner of the Droid you should see it changing between those 2 readings as you move your finger over and away from the sensor. On mine that would work properly in a dark or dim room. I then tried the same thing with a bright light (or in the sunshine) and the sensor would get stuck on "3.0" which means it's constantly detecting something there.. even though there isn't. Which would explain why the screen dims out and never comes back. I'm not sure if everyone is having the issue only in light.. but that's the way it was for me, amongst a few other people in this thread. Hope I helped!"

    I'm going to try this tomorrow to see if mine gets stuck at 3.0. Try it and see what happens!

    Cheers
