Hi all,
Suddenly one day, my camera "searching window" (the whole screen) was black, both in photo and video mode (otherwise everything is normal). The camera captures both photo and video like normal, but the screen is all black, so it's very difficult to take good pictures. Everything is normal when I select camera on the taskbar, but when I tap the photo or video icon on the right the screen goes all black. I have no idea why this has happened. I had not done any change to any software for several months, and everything worked perfectly until then.
A soft reset did not change anything. I have previously had an analog clock and a Windows Beta 7 theme installed (used TF3D Config Tool and Total Commander), but they are uninstalled and caused no problems. The camera also worked normally with the Beta theme installed for many months. I uninstalled the Beta theme with TF3D Config Tool (restore default) because of this problem, but now my phone just has the standard menus again, and the camera problem is still there...
Does anyone have any idea how to solve this?
Any help would be greatly appreciated.

Happened to my Fuze. Ended up reloading ROM (Dr. G's Clean).
Haven't had that issue again.
Hi all,
Got the Galaxy S for a month, pretty happy with it. Yesterday, the brightness suddenly gone up. The worst part is the display lost the gradient scaling and it is replaced by colour bands!
Apps like the stock video player for example. Before the video is played, you can see the grey control bar at the bottom covers by a lot of colour bands. The colour of the movie is all washed out as if you were playing it in 8 bit colour mode. Where the same avi played okay before, crystal clear and colour was rich.
Same thing with the charging screen while the phone is off. You can see the colour bands on the grey area of the shadow of the green battery. Just wondering if anyone has the same problem?
Cheers!
Factory reset :d
Tried all that full factory wipe, data reset, flash to different rom. Nothing works
Then your device's probably faulty. replace it.
Pretty certain it is. I took a screenshot of the video player and it looks fine but on the screen, you can still see those colour bands meters away.
I guess this indicates the LCD is faulty.

The galaxy s has no LCD its LED
Ive noticed when you slide down that tray from the top, when closing it mine has MANY TIMES switched to full brightness. But simply tapping the brightness button on the multi widget thingy makes it go back to how I want.

Thats because you can adjust the brightness by sliding your finger accross the notification bar.... doesnt work if you have auto brightness ticked...

Hi I have the exact same problem! But I didn't notice it before now wen I saw this thread. But all the colours are just fine when I play a vid, it's just the grey controlbar that is by many stripes of different colours, looks like 8bit colour. But when the vid starts playing its just fine, because it gets transparent. Should I get this phone changed, have just had it a couple of weeks.

Hi Radat,
I posted more info in the other forum including some screenshots. http://forums.whirlpool.net.au/forum-replies.cfm?t=1520586
Hope yours okay. I am going to call Samsung tomorrow.
romhunter,
yup, saw the screenshots, looks like quantization problem i.e. that colours are using fewer bits than normal. For example, RGB screen might use 24 bits per pixel, 8 bits per r/g/b colour, the screenshots seem to suggest only 5 or 6 bits per colour.
Hopefully this is just a software glitch, though you said you already tried factory reset / wipe, could it be a loose cable wire somewhere or maybe a problem with the screen to mainboard connector?

On my sgs, there is a green colour attached to to the grey colours, I can see it really good when using Screen test app on the gray scale screen, all grey is sort of green!

Just got a brand new device. Used it for about an hour, then the exact same thing happened - out of the blue.
Any possible home-front solutions? Having to take it to be serviced is a PITA for me ATM.
Mine definitely seems to have banding in the video player control pane before the video playback starts. Can someone please post a screenshot of how it should be? I haven't seen the banding issue anywhere else except the battery charging indicator when charging the phone when it's turned off. And as far as I remember they were always like that.
So can someone please post a screenshot of how it should be for me to compare.
I have the same problem appeared after upgrading to Froyo. Brightness increased (even it is high in the lowest setting) and color saturation also increased. As a result, i see bandings or lines where a color gradient exist. I added an example photo from "Samsung Apps" page. You can easily see bandings on the bottom. I see such things in a PC screen if color adjustment is not optimum. So there must be a way to adjust screen saturation and brightness by a software through registry i think. It seems like a software problem. I think it is a very rare problem, i found few people on the web complaining about it. Mostly HTC Desire, which use also Samsung Amoled screen, users complaining about it.
I did everything said on forums to solve it but no way. I flashed many different roms both eclair and froyo, use a software given in HTC forums to change RGB color, changed color settings through video player etc. Nothing worked. Please help

I looked at ur pic. I honestly dont see any problem with it. What is this banding ur talking about?
Sent from my GT-I9000 using XDA App
Bottom of the screen, around "2010 Samsungs Electronics". This part should be a smooth color transition from blue to transparent but there are circular lines between colors. Is your screen the same.
Another example. The one on the phone looks white on the upper part where a color transition from dark to light black exist and there are visible lines. But normally it was looking like the other picture (taken from notebook screen) before this problem
ah on that screen i already see 8 shades of blue, most be around 4k colors .. bummer though, it's normally a software problem, doubt that a conector has come loose. (but possible if it's a pimped up composite plug with Y/Pr/Pb, .. eh still impossible cos it's getting decoded before that)
hi
i bought a used samsung galaxy s.
its working fine
but my problem is, its showing keyboard letters n horizontal bar when on white screen.. its not clearly visible but i can see it only in white colour display while watching and video which have bright colour.
n firmware version is
2.3.5
baseband version
i9000xxjvt
i took a screen shot with screen capture n viewed it on ma laptop screen n its not showing any letters dere plain white but when i saw on dislpay it shows,
im new to android
n i didnt insalled any rom by myself,
dey were pre installed
any help plx
is it rom problem or display dieng?
You have screen burn, like you can get on flatscreen TVs. A static image has been left too long on the screen and it's 'burnt' into the display, which is why you can't take a screenshot of it.
See this thread: http://forum.xda-developers.com/showthread.php?t=772528
so this means my phone is defective?
n one more question ?
im using tango for video call why android camera rotates to 90 degree its really frustrating even in skype u got to hold it horizontaly.
It's not necessarily defective, it will happen to all LED screens eventually, you can mitigate the effects by not having the brightness on full all of the time.
I think the camera issue is a kernel problem, I don't use it so can't help.
Thanks anyway

As em new on android, how can I turn off notifications for specific apps. Like in iPhone there's an option for push notification to turn off for all apps or some.
N what is background data?

Anyone??? help me how to turn off push notification for specific apps.
Sent from my GT-I9000 using Tapatalk
These are things that you could quite easily look up yourself. I think you're getting push email and notifications mixed up.
To stop apps displaying stuff in the notification bar you will have to go into the settings for those individual apps.
As for background data, well; surprisingly, it means data traffic in the background: twitter, facebook, google sync. etc.
Been doing some searching, but there doesn't seem to be much info regarding the different colors and frequency of flashes that the LED notification light is capable of, depending on the notification received on the Nexus 4, so here goes.
This is just regarding the stock setup without LED modification apps, etc. So far, I have found that the LED has a few different patterns and colors depending on the type of notification that you receive. I am also wondering if there is any way to adjust the behavior of LED notification light in the stock configuration without additional apps or rooting with custom ROMs, etc. I have checked around within the settings of the different apps but aside from a few giving the option simply to use the notification light or not, it seems that it is not possible to adjust the behavior. Here are the details that I have discovered so far:
- Gmail, stock email app, stock text messaging app, others? - White LED, flashes once every 10 seconds
- Google Voice messages, Ebay app, Official Twitter app - Green LED, flashes once every 2 seconds
- Yahoo Mail - Violet LED, flashes once every 2 seconds
- Facebook, Tasks app, Plume - Blue LED
- Flight Track app - Yellow/Orange LED
- Google Messenger, Calendar, others? - No LED notification flash
This is just what I have observed so far after about a week with this awesome phone. Feel free to add to this list based on your observations and I will update the list. Thanks!
There won't be any way to adjust these without additional apps. It's left up to each particular app to support it and pick a color.
I seem to remember the old TweetDeck app was yellow.

All apps can do different colors, but it just depends on the code. The Google+ used to use Red LED notifications, but they've since returned to using green (I think this is a step-backward, but whatever). Yahoo Mail did Purple when I last used it, and Flight Track uses Orange/Yellow. I suggest just downloading LightFlow or Rooting/Flashing a custom ROM for increased control (you can even specify blink frequency and other settings). The problem is, not many phones have had RGB LEDs, so App Devs have no reason to support them. With the GS3, New RAZRs, and the Optimus G/Nexus 4, hopefully this changes, although the LEDs seem to behave weird on some phone models, especially the RAZRs...

could the red LED be for sync error? google mail had an outage the other day.
Facebook notifications are blue on mine, which is neat.

Good to know, although I don't use Facebook right now.
My LED didn't work from the factory, installed light flow and now at least it works the way I would have wanted it to from the factory.
I wished Google + would use the red LED again. I thought it was cool with the FB blue and G+ red.
Plume (Twitter app) also is Blue by default but can be customized in the settings.
Just got an eBay notification and they use green too. I would have assumed yellow....
Edit:
Forgot to add, the flash rate is fast, like on one second, off one, then back on.

Get Lightflow:
https://play.google.com/store/apps/...yYWdlY29uc3VsdGluZy5hbmRyb2lkLmxpZ2h0ZmxvdyJd
It'll take about an eon or so to set up, but once it's up and running it'll change your life. I have customized the LED notifications for all of my different accounts/apps in such a way that I rarely even turn my phone off vibrate anymore - I can tell exactly what is waiting by looking at what color(s) are displayed on the LED.
Good info and thanks for the comments! Also I am aware of light flow but am just looking at the stock setup.
Before I go with lightflow, I'm going to need to see two things. 1. Full compatibility with the N4 (there are bugs) and 2. Proof this won't drain my battery or prevent notifications from appearing. My battery isn't doing too hot and I don't need something else draining it!

One of my LEDs is dead
What color LEDs are there in there? I'm assuming RGB
I noticed my colors are off, tried several LED control apps, particularly "LED Tester", and none can get the Blue LED going. And my white is yellow. G and R are fine. Any advice beyond LED is dead?
I'm so sick and tired of QC on this phone ... I think I'm done with it. Returning for a refund, money wasted on now useless accessories, some of which are still in the mail

I prefer Light Manager. Much easier to set up. Plus notifications for charging.

Lightflow has notifications for charging. I say it's a pain to set up initially because picking a color for 41290 different notifications can take awhile, but the setup really is quite intuitive. It's been changed a lot in the last couple months - might be worth looking again some time.

I've had no issues on my Nexus 4 with it. It's never drained my battery on this nor my Galaxy Nexus. Its memory footprint is tiny and it has no reason to wakelock the phone since all it does is intercept when a notification shows up (so the other app is what actually wakes the phone). It's really well designed.

One question for you. I know that because of how light flow works, if it doesn't support an app the led won't work on that app even if that app has it's own led ability, but will the phone still display the notification (minus the light) for an unsupported app?
Sent from my Nexus 4 using xda premium
If you guys are rooted and installed the stock AOSP browser, for some reason Light Flow breaks it.
Once light flow is installed and permission is set in accessibility, the stock AOSP browser starts behaving badly and stops working correctly.
The autohide url bar stops working, when changed to full screen mode there is either a glitchy image at the top or a blank black area where the url bar is supposed to be. Problem completely goes away once light flow is uninstalled.
Very frustrating because I can't stand Chrome, and I need the AOSP browser + lightflow. It's either one or the other.

As far as showing up in the notification bar? Absolutely. The apps themselves control that, not lightflow.
Personally I don't have any apps that lightflow doesn't support by now, but I'm sure there's some out there.
Hi, so I use dark theme in every app and I recently noticed that if I have brightness set to low, some text (mostly blue colored) looks really bad on a grey background - the grey around the text is darker (only pixels on left and right side) and the text looks blurred, however if I make a screenshot and open it on PC it's fine.
I use my Z3C for over a year but I started noticing this only recently (in apps I use for months) - is it possible that something happened with the display (not sure what if high brightness is ok)? Or this is normal and I noticed it just now (that would be very weird though).
