HTC EVO 4G : Screen Turn Black With Camera - Video Image
Aug 2, 2010
So I just finished my ota 2.2 update... since the install everything has been working great however when I open the camera (still or video) it will not open. The screen will turn black with the camera or video image and then go back to the home screen. I have tried restarting the phone with the same results. Any suggestions? Has anyone else experienced this? btw I was unrooted and stock if that makes a difference prior to the update.

Continually The screen will go unresponsive, and then turn black and the only things that'll light up are the bottom buttons. Sometimes the screen will just freeze without going black... and i constantly have to do battery pulls.

Any word on whether or not the Evo will have image stabilization for the video camera? I had a Vado HD for a while but the shaky video drove me crazy!

I then checked youtune on my browser and same problem..

So I was trying to show off my phone today and when I tried to take a picture the screen was black. It won't take a pic or anything. This is the first time I've tried it since the update.

I've been playing with my camera today, and finally figure out how to take decent pix, but after scrolling through my album, I tried to go to the camera again, but now everytime I try the screen is black. And it stays black even after I remove my battery. A few times, I couldn't even get to home--the screen just stayed black.
Now it's still black when I go to the camera, but at least I can access home without having to remove my battery. I called Bestbuy and they said I can exchange, but I'm afraid I might get one with a messed up GPS. :-( Will Bestbuy fix it or make me exchange? Will Sprint fix it even though I'm still in my 30-day trial?

I bought a bricked Bruneau tablet and wanted to stock flash it. But the "script" named folder that i put it on the sdcard was for other kind of wonder media processor. I have a WM8505+ procesor and the software was for WM8605. Now the tablet does not turn on, black screen, no sound nothing. I saw on other forums and youtube that i can shortcircuit 2 pins from a Samsung chip on tablet motherboard but it`s not working.

HTC EVO 4G front-facing camera test: good, but it records a mirror image | Google Android Blog
First off I have to say the quality from just the camera itself is excellent for a webcam IMO.
The weird thing is that it seems to record a mirror image meaning if something is on the right in real life it's actually on the left in the video. The article explains it. You think it's something that can corrected through an update?

I was just sending a text and all of a sudden i had the black screen of death and then the phone seemed to reboot itself with an image of a red triangle with an exclamation mark in the middle of it
I proceeded to try and turn the phone off but it gave me lots of options with a white screen, i couldn't get it to do anything so i took the battery out and then it started normally.

I'm just trying to play a local video that is a resource with the MediaPlayer class in the most simple way possible. I have confirmed that the video works with players that I download from the marketplace, so I'm assuming that's not the issue.
The problem is that I just get a black screen with no video. There is audio from the file playing though, so I know that the file resource is being accessed correctly, it's just not showing anything on the screen in the emulator.
The one other note is that at any time whenever I try to access getVideoWidth() or getVideoHeight() I get this (non-blocking) error:
ERROR/MediaPlayerService(24): getVideoSize returned -1
Any ideas as to what I could be doing wrong?
import android.app.Activity; import android.os.Bundle; import android.view.SurfaceView; import android.view.SurfaceHolder; import android.media.MediaPlayer;
Code...

I want to get rid of the sound that plays when you turn on and turn off the phone, and the video too if possible. But I can't find the file on my phone to delete it.

I am creating a little application where I use the Android Camera class. Everything seems to work but the result is a black picture. I think I forget to set a parameter. Do you have any ideas on which parameter I must set up ?
The code:
public boolean takeIt() { ImageCaptureCallback iccb = null;
try { String filename = "photo.jpeg";
ContentValues values = new ContentValues();
values.put(Media.TITLE, filename);
values.put(Media.DESCRIPTION, "Image capture by camera");
iccb = new ImageCaptureCallback(new FileOutputStream(new File (dataMgr.getRoot(), filename)));
} catch(Exception ex ){ ex.printStackTrace();
} camera.takePicture(mShutterCallback, mPictureCallbackRaw, iccb);
return true;
}

I have a Sero 7 Pro, and for some odd reason, the camera stops. Doesn't stop working, just goes black. I have to stop recording and restart. Sometimes it will record for hours, other times for 20 to 30 seconds. I use it as a dash cam and it's getting irritating.

I couldn't find anything specific through a search, but whenever I get an email on gmail I get a white envelope notification. That is linked to the gmail folder. At the same time I get a black envelope with a white outline. I cannot figure out what email folder/widget/whatever it is linked to and I have to manually clear the notification.
Is there anyway to turn off the black envelope?

When I start the camera up, it shows nothing but black (no, the lens isn't covered in any way/shape/form). If I hit the track ball as usual it acts as though it's taking a picture though it's also nothing but black. What am I missing here? BTW, I'm on 2.1 and did a factory reset two days ago.

Often at night when I use phone lowest brightness is still bright so I found apps which can dim it further but then they loose screen contrast too making it difficult to read.
Is there any app which can make night mode of selected apps (browser/gtalk/gmail/other few user selectable apps) background dark & font light / white similar to youtube app?
UC browser had this night mode earlier but latest version they have removed this feature. Ideally such app should be time sensitive & as the night time approaches it should start applying the night mode.
