    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

    Blank Screen

    I've had the same problems with the screen going blank/black whenever a phone call is complete. This has happened a few times since I've own the droid. Which has only been a few days. I've tried everything to have it come back on. The only thing I can do is pull the battery and have it reboot. has anyone figured out how to remedy this issue.

    This has happened to me too. Tried the on button, sliding out the keyboard, nothing... The BACK/MENU/HOME/SEARCH buttons illuminated and the LED was blinking because I had a text, but the screen would NOT come back without pulling the battery.

    I set the screen to NEVER go off and I haven't had the problem since, but I also haven't used the phone a lot. I don't think it should have to be that way, now I worry about forgetting to turn it off and wearing down the battery so hopefully another solution comes up.

    I've had this happen to me more than once.

    Hopefully it will be fixed, it has something to do with the sensors i think

    I have had this problem about ten times. I haven't tracked whether it only happens outside. (I do still have the plastic cover on because I wasn't sure I would like the Droid.) When the black screen has occurred, I can't call up the dial pad or turn on the speaker phone. The worst part is not being able to end the call (and racking up minutes). The phone just doesn't wake up so that I can use any controls.

    I seem to have the same problem with my droid. After completing a call, the screen went blank and I wasn't able to awake it. I tried the power button or the volume buttons which worked before, but not this time. I have a screen protector installed by a Verizon tech and the sensor wasn't covered. What worked for me after doing 2 battery pulls to no avail, was to connect the droid to the charger and it works fine now. Not sure why the battery pulls couldn't bring it back up.

    smokinfish from the other thread actually gave a pretty good solution. Screebl is a a free app that lets you choose how and when your screen blacks out when you make calls depending on the angle that you hold the phone. I tested it and it works very well.

    Hopefully theyll actually release and OTA fix for this problem since it shouldnt be occuring in the first place since I personally dont like apps running in the background all the time...

    This continues to be a sporadic problem, which is occurring inside as well as outside. I have tried all the suggestions sent to this forum, but the only one that works every time is opening the keyboard. What a drag. I just looked at the list of "enhancements" that will come with the vaunted upgrade, and I don't see anything that addresses this issue. Sigh.
