HTC EVO 4G :: Camera Doesn't Work / Displays Blank Screen
Oct 26, 2010
Yesterday I was listening to Pandora and I wanted to snap a picture with my EVO, so I hit the 'Home' button and then opened the Camera app. After that the little camera icon showed in the middle of the screen for a second or two and disappeared. Next the screen was blank. I also tried the camcorder and the screen was also blank. I've done many resets/pulling the battery out and I still have no luck. Any ideas as to what is causing my camera to not work at all? The only way to exit out of the blank screen is to press the 'Home' button on the phone.

I'm looking for a camera app that displays a picture on my screen in transparency when taking another picture with the camera of the phone in order to do the same pic as done before ...
Any app already exists ? Or is there a tip to do this ? Taking a picture with a printed photo in the other hand is not very effective.

First of all. So I picked up my EVO a couple of hours ago. I was messing around with it, and switched the camera to the front one, which has now caused the screen to be blank, just black. None of the buttons function when it's like that, except the home screen. Please let me know if anyone knows anything I can do about it tonight.

I just bought this phone off of CraigsList.When I try to launch the camera, whether using the dedicated camera button on the side of the phone or using the icon on the screen, the display goes blank for one second and then goes back to the Home screen.I called Tmobile, and they just had me do a hard reset which didn't have an effect.

I'm running a standard camera preview (i use the camera api demo as a reference).
When i hit the capture button, there is a black screen for a good 1/2 second until the captured image appears.
My question is how can i freeze the last image being previewed on the screen while i do the capture work ? I don't mind that the quality of the displayed image is not as good.
If i hit camera.stopPreview() -> that goes into the black screen which i don't want.

I'm creating a basic Mapview application which will display my current location on the google map. Initially i had many doubts while creating the application, but thanks to android developers archives that helped me to reach this point. I have followed almost all the threads on the android developers site but still unable to see my location on the google maps. It always shows a white screen on the emulator with google image at the bottom. Please help to make it work. From most of the threads I learn that we need to sign our application with the correct fingerprint. I did so but unsuccessful.
The following will explain the steps:
1. Using sdk version android-sdk-windows-1.0_r1
2. Created a new android application.
3. Signing the application:
a. C:Program FilesJavajdk1.6.0_13in>keytool.exe -list -alias androiddebugkey -keystore "D:Profilesfknq86Local SettingsApplication Data Androiddebug.keyst ore" -storepass android -keypass android
b. Certificate fingerprint (MD5): 75:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:33 where XX=some alpha numeric data
c. signing up for an Android Maps API key!
Using link http://code.google.com/android/maps-api-signup.html 4.
Code below: There are 2 applications
1. Find Me
2. ShowMyLoc.
FindMe has a button which directs it to ShowMyLoc (using Intent) to show the location on the google maps. For simplicity sake i'm pasting the code only for ShowMyLoc app.

I have so far found two bugs in Galaxo 1.6.3:
a) Speaker doesn't work in call (very weak). works well in ringtones etc.
b) Scrolling contacts by letter doesn't work.
Other than that this is a leap forward, especially with the overclock options!
Both bugs, as well as others, fixed in 1.6.3.1 update!

I have a count down timer that when it goes off (to zero) it checks to see if the app has focus. If not it launches a notification in the notification bar. When you click on the notification is re-opens the app. Now all of this works fine but if the screen happens to go off, the timer keeps going and the notification is available at the right time but never actually vibrates or rings until i turn the screen back on. Then it displays the notification like it was waiting in a queue or something.
How do I get it so that the notification manager will actually alert the user when the screen is turned off?
Update: If I set the timer for 2 minutes, it takes another 2-3 minutes for the notification to actually work. So it does work but it's on a huge delay! Code: So I setup the notification service when the app loses focus, and when the MyCount1 is finished is checks if the app has focus and if not it shows the notification. This all works when the screen backlight is on. Once it goes off it is unreliable.
@Override
public void onWindowFocusChanged(boolean hasFocus){
if(hasFocus == false){
mFocusFlag = false;
ns = Context.NOTIFICATION_SERVICE;
mNotificationManager = (NotificationManager) getSystemService(ns);
icon = R.drawable.statusbar;
tickerText = "Check the timer!!!";......................................

I have suspected this on every ROM I have run (stock 2.1, all tranquility roms, and now rubix 0.3 (which I love except the single unexpected shutdown of the phone once).
My screen just doesn't turn off no matter what the settings/display/screen timeout is set to (30 sec, 1 min...)
I test it by turning on the phone, sliding to unlock and then staring at my homescreen with a stopwatch. It can be 5-10 minutes before it turns off.
I have interrogated with spareparts and the phone does have a high percentage of "running" from bluetooth and wifi, but isn't the screen supposed to shut off even with those background processes running??
I don't have anything special installed for power management, just stock stuff.
I went to the market and found some power managers but I don't have any confidence a third party app will solve this problem.

When at the home screen and then moving two screens to the right I get to what looks to be some type of image player in the middle and it has the Media Share, Blockbuster, Camcorder, and Gallery at the bottom.
While playing around with the camera I just took some random photos of junk and have since deleted them. But now in the middle of the screen I still see what seems to be the last image I took. Yet the file isn't actually on the phone or card. The round button in the middle (with the square around the 'play' icon) is selected but red (when I touch it it turns green and used to scroll through the photos before I deleted them).
How do I get this ugly blurry test image out of this screen and back to the way it was before?

I was in the pool when I dropped my phone in it. It was only submerged for about 2 seconds. I was at a friends and they didn't have white rice so i had to put it in brown rice-- all day. Then today I put the battery in it and it acting the same, everything works but when I touch the screen it doesn't do anything. It has now been in a air tight sealed bag full of white rice for about 3 hours... It still doesn't work.. I have college tomorrow and I need my phone...

I have noticed that after the last update, my touch screen doesn't work for a few seconds on random occasions and then works again after about 3 or 4 seconds. when I'm reading a book and they're about to reveal the mystery or enthusiastically playing a game and it stops working, I get increasingly frustrated that I can't turn the page or that I lost the game because during the last few seconds my touchscreen decided to temporarily stop working.. I just want to make sure there's not something wrong internally.

the GPS on my Desire is shocking - it point-blank won't work if there's ANYTHING over my head, so useless in cars/trains/buses, and if i'm out on the street it'll either not work at all or take upwards of 2 minutes to lock a signal. was chatting to a friend about it this weekend, and he whipped out his nexus one and had a locked signal within seconds of opening google maps, whereas mine still refused to budge. have i got a duff handset, or are other people finding this an issue? i'm on Orange, although i'm presuming that GPS isn't reliant on the carrier...

I'm trying to determine whether or not my phone is defective, or if this is a current problem with the Cliq.
Of the apps I've downloaded, only a few of them have worked. Of those few that work, some don't work right. Has anyone had problems with these apps crashing on them, or just not working correctly?
- Nice Battery (see description at bottom of: My Ultimate CLIQ settings (so far))
- WeatherBug (kept showing the wrong location, crashed when trying to change location)
- Snake - doesn't work just says its "paused"
- RingDroid - crashes when I select the "Facebook Pop" button
- Layar - screen is rotated 90 degrees at all times
There have been others, but usually I just uninstall them right after discovering it doesn't work right.

I've had an HTC Desire on Orange in the UK for about 6 weeks and it is having persistent problem. Firstly despite having a strong 4-bar out of 4 signal, online services and the internet do not work at all when a 3G signal is being received (e.g. news, weather, all widgets, internet, email etc).Calls and texts do work however with a 3G signal.But when a 3g+ signal (HSDPA) is being received, all internet services as above work fine.However, when a 3+ signal is being received, the phone does not make or receive calls or text messages, and often fails to send texts. Calls I make immediately shut down (bleep + �call ended�), and incoming calls from other people go straight to answerphone. Also often when turning the data connection on/off, it freezes and has to be rebooted, and turning airplane setting on and off does not fix the problem.
I have also tried the different network settings (GSM, WCDMA, auto, etc). �GSM� sends and receives calls and texts but doesn�t work (or is incredibly slow) with internet, and �auto� and �WCDMA only� show the problems as above.I don't think this is a network/coverage issues as, as I have seen many people reporting these same issues on other networks and in other parts of the UK, and I have read that other people are having to manually turn off HSDPA to be able to make calls (using an app?). Even if I can stop HSDPA from connecting to make sure the phone works, I still can�t use the internet at all on 3g � even GSM works better!
Finally, when I connect to a bluetooth device (e.g. car and headphones) the phone will connect briefly, and then randomly disconnect. I have also seen this issue reported elsewhere.I very much like the phone and don't want to get rid of it, but these problems are making the phone unuseable.Also I don't know if I should be contacting HTC or Orange about this. Will the upcoming Android 2.2 fix these problems?Anyone know how to fix this or if I need a new handset? Are there any apps that can help? Also does the Nexus One have these problems and are they fixed by Froyo?

This was reported in the other thread about X8 Issues, but thought to start a new one to gather feedback from users. It's about the ''black screen'' freezing issue encountered by some users. I have had this several times since owning the phone for a few weeks, so it is a recurring issue. Problem: The phone hangs or appears to be shut down or become unresponsive suddenly. Pressing the hardware buttons doesn't help as the phone doesn't react at all. Solution: Take out cover and battery and restart.Observations: From my own observations, it's not actually a shutdown but a major freezing/hanging. Sometimes when it happens, I can still see vague shades of the display at an angle. After leaving the phone for a while in the pocket, the phone comes back to normal again. Not sure if this is true for all users with this problem. Anyway, gathering more feedback to see how prevalent the problem is, to evaluate whether I should take it to the SE service centre, or whether doing so will help at all.

I have a listview that when you click on an item it will take you to a WebView that displays some static formatted text associated with that list entry.
I had it all working with a TextView but I wanted to be able to use HTML formatting for the text and figured the WebView was the way to go. Right now it is just supposed to display a generic link for testing purposes but when the viewContent intent starts it just goes to a black screen. I can go back and pick another entry and it also just shows the black screen.
I'm not sure what code you are going to want to see so here's the viewSection class file and the viewsection.xml layout.

I have a layout with a TextView and a List, and in onCreate() I have the TextView request focus. On the G1 and emulator the screen comes up with the TextView having focus, and the on-screen keyboard will display when you tap on the TextView, but on the Galaxy apparently the on-screen keyboard is always displayed. Does anyone know why this would be so? And why would a phone without a keyboard act differently from a phone with a keyboard that's hidden--shouldn't they follow the same logic?

Suppose my application xyz stores a few contacts(just like in the address book/ telephone book). Other contacts are by-default stored in my Android address book. Suppose I receive a call on the handset with my app xyz running in the background. All I need is to fetch the Caller's name from the application xyz and display this name as" Akash Calling..." instead of "+91... calling..." assuming that caller's details are present in the application say, his name and none of his details in the actual address book. Is this feasible.
