Does your Galaxg S2 has a dead pixel? - Galaxy S II Q&A, Help & Troubleshooting

I am starting this thread to let everyone know about the quality control samsung has, whether the device was properly tested for quality issues hardware wise or things were rushed up at samsung.
To check your Samsung Galaxy S2 for dead pixels:
1. Just open the dial pad and dial *#0*# which will bring up the lcd test menu.
2. Now touch the red, green, and blue buttons one by one to check for dead pixels.

i might of not had a dead pixel.. but i had 3 phones that had a blue line across the screen when viewing a white or grey background.
Also the phone gets super hot and i can now smell something from it.. from the top left of the phone. Gonna send it back today and not get another one.. might wait for the iphone5 or see what else comes out.

There is already an ongoing thread regarding dead pixels, maybe give that a read? Will save duplicate posts

Grey Lines When Temperature Down

This morning when I woke up
I realized there are some horizontal grey lines on my phone screen
Then I was outside jogging
I noticed the lines are gone
When I back to my room
I put my phone right under the air conditioner
After 15 minutes
When I pick up my phone
Those lines are there again..!
I bring my phone to my living room
My living room is without air conditioner
After 15 minutes I watched the lines are disappearing
I was so curious
Then I again... Put my phone under the air conditioner in my room
Those lines are back!
After this experiment
I assumed the temperature cause these grey lines on the screen
Is anyone also have the same experience?
Facts:
* even without *#0*# the lines are quite visible
*I lived in jakarta, indonesia my AC is set at 25C
*Outside my room without A I reckon about 32-35C
*stock kj2 with speedmod kernel
I'll wait if those lines keep coming back
Then have to visit samsung service center and the them about this.
Pics would be helpful ... because the early batches of SGS2 had the Yellow spots/Line issues!
i had that issue too. when i flashed MIUI rom and i could see horizontal grey lines on the white notification bar... so i did some research and its the hardware issue.. sometimes flashing a new rom goes a way but comes back randomly..
It is hardware issue
Just bring it to service center
They replace the whole screen for you

Apparently not.
Don't worry, I had the same problem. It happens when it's pretty cold outside. However the problem just dissapeared..
I had the same issue on my 26" led monitor, Galaxy S, Galaxy S II which bought in May and newer Galaxy S II which bought in November too. My room is 22C and outside is -8C.
Is this be a screen virus Its more noticeable on purple and grey colors. Android 4 uses grey colors and my CM9 looks bad.

Light leak from left touch key in dark ??

Hello guys, now its been almost a week since i've had my s3 but yesterday night before going to sleep, i just unlocked my phone in pitch black darkness and what i saw was white light originating from the left capacitive key extending to the screen which looked really bad like a screen burn or some kind of weird white patch on the screen as if i've cracked it, and if it were from both keys i cud have convinced myself that its normal but its only the left key! and its not at all noticable even in a little light and if your screen is not using a dark black background.. so what do you guys suggest me to do? can you guys check your phones in a fully dark room with black blackground and touch keys lit up?? and will my warranty consider this an issue and cover it? i feel so bad right now :/
I'll check later tonight, but I generally have those lights permanently off since my S2 as the intermittent on/off at every screen touch is an annoyance particularly when watching videos
I would suggest turning them off, the buttons are easy enough to find in the dark plus you save a little bit of battery.

Yep right its leaking, turn mine off ALWAYS plus its better looking when turned off
i dont know how but getting to know that the rest of you have it, i feel fine now and as most of you said, i'll turn them off, thanks
how do you turn them off?

i dont have it and i also turn off those capacitive lights. either you have to live with or go far an exchange.
You sure?
Are you sure?
It can only be seen in a dark room and with a black background on the phone.
I dont like having flaws on my new stuff. I am gonna try to exchange it.

I went to the dealer and they said that they would send it to the shop to check if it really had a failure, and if it had a hardware failure they would exchange it in one week!!!!!!!!!!! i will just stay with my phone as it is. It is more possible they will really screw it on the shop with something really bad to worry about, and I bet that the next one will have the same flaw or another even worst, so I prefer to stay with mine.

Screen problems on 4month old S2

I have noticed some horizontal lines running through the screen on my S2 when light images are displayed. (Also shows on green test screen quite clearly)
They are light bands about 1mm wide and running across my screen at various points.
There is also slight burn in of my status bar, you can see battery and clock if you look hard.
Just wondering if this is a normal occurrence and something to put up with or if it's worth me getting it replaced under warranty.
If I return it and then in 4 months time the same happens it's pointless. Also I would hate to return the phone for screen replacement and then get another screen with maybe a dead pixel or something.
Any help is very much appreciated.
Thank you
can no one help......?

Send it to repair centre, it's definitely a faulty unit.
Your repaired/replaced phone will not have repeated issues.
My phone is a year already, and everything is still prefect

[Q] One Max Screen Flickers

Pardon me if a thread already exists for this but I have tried to search but didn't find a thread describing this problem any where. Redirect me if you know of a thread like this.
So here is what I am experiencing. My One Max is a week old but from day one I have noticed that while i am typing a text message or email screen brightness increases a bit as soon as I hit any key on screen. Sometime it happens sometime it doesn't. I have also noticed that it only happens wherever key pops up on keyboard e.g E, R, G, O etc etc or it happens when I am scrolling messages or any thing which is in Black and White contrast (May it be messages or a web page with different dark and light pictures/rich text)
Mine is a brand new Stock Phone. No unlocked bootloader, or S-Off or Custom ROM or something of that sort. Brightness is at around 30%-40% in settings. Phone CID is HTC__J15 (Arab CID and International version).
I don't think its an hardware problem but wanted to share it with you guys and find a reason as well as a solution to it.
Cheers.
It sounds like your light sensor is adjusting itself very rapidly. I can't confirm if that's an hardware issue as your environment or fingers might have preventing light from falling on the sensor.
I would suggest you to ask a friend or a family member use your phone and see if that happens to them also, this way you could make out if your way of handling the phone is creating the issue or the hardware might be faulty.
Might be you were typing in a landscape mode.
When typing those letters, your left thumb blocks the light sensor.
If yes, then I would think It is normal.
It is just how do we use this beast.

As far as I know light sensor is right at the top with speaker. I dont use phone in a landscape mode.

I agree. This flickering doesn't matter to me too because this phone has so much more to offer that bit of a flickering wont bother me at all. I bought Note 3 for $710 and sold it right after 10 days for $600 because I didn't like touchwiz at all. But this One Max is an ultimate phone for me for next two years I believe
I've noticed it but only in low light situations. I just set my brightness at night or in dark places to eliminate the issue.

I have this too..... Just when brightness is from 0 - 24 % ( if flickers) (by higher back-light it is away - but it sucks, when you wanna watch movies in night You think it is a thing for reclamation? And have you too that the upperside of the lcd below the sensors and front camera is more white (from the back-light) than the lower side cca 1cm by the hardware buttons? you can see it in white background by web browsing.... etc...

No, I haven't noticed any brighter spot under front Cam or over hardware buttons. Don't have this problem at least in my phone but yes flickering is something that I notice regularly.
Its not something which bothers me in a great deal but I believe we must get a perfect product because we spend a serious amount of money at the time of purchase. In my country HTC One Max is for $700 and I believe this is a lot of money to spend on a phone at least.

It is on my phone bad back-light. (on upper-side you can see more white light from the light-tube... or what is there, down by hardware-buttons is instead less light it seems like burned out)
These two things with flickers - flickers less than the back-light worry's me.
You think it can be solved by reclamation on warranty repair. (i´m afraid that they say, ... this is normal by these kind of lcd) and they do nothing...
But i will it send because we are customers, and we payed not for a brick bud for high tech.... so i hope it well be good.
Before i had no problems with htc warranty's..... ( i try to show you pictures of it.... )

I certainly believe that this must be covered in warranty. None of us paid that much of an amount to own a faulty handset. If they tell you that all units are like that then you should take your money back and look for any other phone. My brother owns HTC One, my wife has HTC One X and they don't have this faulty backlight issue then how come it can be a default feature in HTC One Max.

Here are my photos of this issue... On the web-browser you can see, that it is everytime on just the lower side of the phone. On upper side you can see more light .... On the video is the issue for further epilepsy... Bottom line is that I use the phone in dark places so, internet browsing, movie watching, is not possible on zero backlight just from 26... 27% it's seems be to eliminated... But my eyes are after that like from welding. So be or not to be ..(welder or epileptic)

One Max screen brightness fluctuations
I noticed this to be the case on my One Max the first couple of weeks playing with it. i noticed at times the screen would get dimmer and dimmer. While it wasn't ovewhelmingly annoying, I decided to disable automatic brightness in settings-brightness and all my screen troubles went away! :victory:

In your video I can see that screen brightness changes and that happens to me too. This happens when webpage or movie has different Black and White contrast and screen goes kind of crazy as what it should do and there it starts kind of flickering. However, Screen Backlight Tubes problem in those photos that you posted earlier, I dont have that issue in my phone atleast. I belive that is something you should get your Unit fixed/replaced from HTC.

Thanks, i search now for a cheap android device for the weeks, when my MAX will be away .... My older phone DHD has my girlfriend, so now i search for a cheap android device and after that i send it ..... .
The flickers .... i see too the problem with the black - white contrast but the normal htc one has it not ... so i think they should work on it ..... and try to fix it ..... maybe could it by a software problem
I newer wanted samsung because of their amoled displays with they burnout - i had this on my phone on samsung omnia with windows mobile..... and the reclamation was a walk through the valley of darkness .... on the end, they told me ... that the oled-lcd how i have it on my phone is normal ... and there is nothing to repair .... ( he had white stripes in it too - so samsung and oled is for me a route to hell)

FLICKERS - HTC REPAIR SAIS THAT THAT IS A attribute
→ behavior
→ cast
→ characteristic NOT A THING TO REPAIR SO I ASK WHY IS THIS JUST UNDER 27 - 30% OFF BACKLIGHT VISIBLE - IT SHOULD BE EVERY-TIME THERE ... ( DISAPPOINTED.... BECAUSE NOWHERE IS WRITTEN THAT THE HTC ONE MAX HAS THIS BEHAVIOR .... HTC ONE HAS IT NOT .... SO SHOULD THE USERS OF ONE MAX USE A SUNGLASSES AT NIGHT ? WHERE IS THE QUALITY OF PRODUCTS IN THIS WORLD DISAPPOINTED - WE CAN GO IN THE MIDDLE AGE WHERE IS NO ELECTRICITY .... OR WHY USE A TOP END PRODUCT WHEN WE CAN USE SOMETHING FOR 40% OF THIS PRODUCT)
THE BACKLIGHT TUBES PROBLEM THEY SAID, THAT THEY SEE NOTHING ... SO I WAITED ON THE PICTURES AND IT IS THERE, HOW MANAGE IT NOW? (DISAPPOINTED AGAIN)
SAMSUNG NEWER .... AGAIN
HTC I THINK NEWER AGAIN TOO THE DAYS ARE GONE WITH THE QUALITY
LG.... OR SONY ... MAYBE ... BUT .... LG WITHOUT THE SD CARD ....

Galaxy S3 Screen Burn in

I own my galaxy s3 for about 2 years. The Problem is, that i have serious screen burn in. I alway See a shadow of my keyboard when displaying a white image. Is there any way to fix this? I know that amoleds have this Problem, but i did not expect that after only two years

I'm having the same issue. Would love to know how to solve this. Although I think the only solution is replacing the screen.
2 years? It can happen in a couple of days if you leave a static image on the screen.
I read a while back that this might work but don't quote me on that. Also, I'm not responsible if anything bad happens.
Try putting your phone on max brightness, displaying a completely white picture and leave it like that overnight. Plug in the charger and keep the display from dimming and turning off.
