Recently I just noticed that there is a small blue shining dot (pixel) on my screen when I turn GN off and it stays there for near 20 sec !
you can not see it even with the smalest light in the room but it is there in darkness !!!
it is in the right side of the screen a little lower than middle ....
any one else notice that ?
is it normal ?
how can I check what it is ?
...
Had this on my GS2, the screen was replaced under waranty.
you have a stuck blue sub-pixel! this should be visible in every picture you display, but it's most noticeable when displaying a black picture (and switching the device off takes about 10-20sec - and the display is still active, but displaying nothing)!
you can test your screen with a test-tool opened with the dialer: enter *#0*#
such a defect is really hard to notice in real life conditions, due to the small subpixel size. also, samsung has no obligation to change your screen because of one dead subpixel, but you can try!
more common is a dead sub-pixel (the subpixel stays always dark), and it's also less annoying. if i would be you i would try to exchange!
Thanks for info
I just test it with *#0*# and there is no blue pixel in the green or red or white or black screens ...
So I just try to ignore it for now or may be change the screen if it gets annoying
Same here. I think is a ICS bug. If i flash a GB rom there is no blue dot. It only appear during 30 o 40 secs when you switch off the screen.

which rom you have ?
I'm on Rocket Rom v2 .
i´m on kingdroid 2.1 but have tried several and the problem is always there except with GB roms.
Try detect pixel and fix from the play store. It helped me fix a stuck pixel on one if my older phones.
I also have the blue pixel when the screen turns off after the ICS update. It doesn't show on a black image either only when the screen turns off. Detect pixel and fix hasn't worked.
BPS ( blue pixel symptom ) seems like an ICS problem or ICS on some devices problem or ...
I tried every solution you can think of but when screen goes off its there for about 20-30 sec and then it goes away.
I tried deferent rom and kernels ....
I think many others has this problem but didn't noticed yet.
For all people experiencing this issue, i would like to tell you that when i got the galaxy note initially, i too had this problem! This problem has nothing to do with software so using Gingerbread or ICS dosent matter. I had taken my galaxy note with this problem to Original Samsung Center. They took my phone to "check it in a dark area" because in daylight it wasnt visible. Then they confirmed to me that it was a screen damage and replaced my damaged screen with a new one free of charge since it was under warranty. So if ur suffering from this same problem please go to your nearest Samsung Service Center OR Outlet where you purchased the phone from and get a screen replacement or phone replacement.
Cheers!
Strange thing is my wife's note has a red pixel. I swear it wasn't there in the start. It goes off 30 secs after screen is off.

Seem to remember having the same issue, had to be very dark though. Occurred with ICS and GB. I think its a hardware issue. I don't know what the policy is with Samsung and smart phone screens with duff pixels, might be worth checking as with computer screens there are tollerances and 'some' manufacturers have zero tollerance where they will accept a return for any pixel defect, others wont. But this occurs when powered down for 20 or 30 seconds and does not show up with screen tests. I guess the QC policy might be thus: if you power down = your not going to be looking at it = it doesnt matter.

Hello all,
I've got the SGS II for about 1 week now and at first I thought it was a software issue. The thing is, when I'm on a very light colored background ( Market, facebook, whatsapp or whatever ) You see smudged out stripes from the text or any picture that is on there. They're all faded stripes. I thought it was banding but this is something totally different.
What's even more weird- it only happens when I'm outside the house, so my guess is that the brightness sensor plays a part in this? When I'm inside the effect is minimal to none but when I go out or to a very bright place, the stripes are extremely annoying. ( will take pictures for reference when I get the chance )
Would you say this is a manufacturing fault?
Please help if you've encountered something similiar.
Thanks!
Here are some images, the stripes are not that evident right now. They seem to get worse when I'm in the sun.
Looks like some polarising effect.
Should I return to the shop to get this swapped? It seems to me that the screen is defect???
Return!! It seems alot of people are having screen problems.
Same issue on my SGS2.
Was perfect during one week then theses anoying stripes!!!
Did you perform a 1:1 exchange?
There were similar problems on the Sensation forum and it was found to be app/widget conflicts.
If you turn off auto-brightness and also the power saving lcd brightness mode under display in settings does it still happen? You mentioned it happens when you go outside so was curious if you adjusted brightness manually if it still happens
Sooooo....
Yesterday evening I changed form litening 1.5 to the stock rom on KF1 with full wipe.
After that stripes where still there.
Went to bed.
Woke up this morning: Big surprise stripes were almost invisible!!!
Battery 40%
BUT
today I used the GPS google navigation during 1h and discovered that theses stripes appeared again and they are very strong.
- No link with app/widget, nothing installed .
- Didn't touch on settings display auto-brightness before the problem. Tried after but nope.
I tried this today
(all credits to Cost from french forum tmaddict)
Flashlight to use white light during half an hour.
Stripes almoust disapeared...
Then picture with high contrast and color.
Stripes came back.
Conclusion :
With SGS2 you can encounter a display refresh problem.
Not solved btw => screen defect => exchanging it today.

hi. i am using 2 phones the nexus s and the gs2 .
and i noticed something on my gs2 and i need to ask you people about it.
the phone isnt like 3 weeks old. its brand new. however i noticed a temp screen burn in on the following places.
when i use the keyboard for txt msging. if i pull the keyboard down " by pressing back ", i can see the squares of the keyboard on the screen for like few seconds before they dissapear.
i also noticed the same thing in the status bar, battery meter. specially in the browser or an hd wallpaper app called " HD wallpaper "
when i downloaded that app. i turned the wireless and went through the app. now its trying to load . if i switch the screen to the side. the status bar will tilt as well. vertical horizintal depends on the way you move the screen. and i clearly can see the marks of the status bar for few seconds before it dissapear again on whatever verticial or horizintal/
what is the issue here ? i cant call it burn in because its not permenant.
i noticed the same thing with Miui on the nexus S. but only on the status bar. nothing on the keyboard.
any idea peeps
is it some sort of memory effect or bad refrish rate ?
Someone else had this. I think it was related to apps or widgets they installed. It's not normal. Do a search and see if you can find the other thread. Try searching on "ghosting."
i was searching through ghosting. is this normal with everyone here ? or some people dont have it ?
i think you should be carefull with your phone, if you leave it to much on the same background it will burn in easelly, oled burn in as easelly as plasmas when it comes to leaving them on the same image over and over again, try see if you can change yours, i certainly have no such issues with none of the 2 i had nor with this one.
PS: depends on what you mean with ghosting, if you mean the pixel response time beying visible when moving an image fast then yes thats normal, even though oled have 0.01 ms response time this one is deffinitly higher as i can notice it easelly.
i have a screen burn in on my Nexus One, annoying at times when i do notice it.
Yes, I have this. Had a thread, temporarly burn in. I can see it when I type a message.
Just when the keyboard is visible and I pull down the notification bar, I can see the contoures of the keyboard letter there... Probably happens with other things but aren't that noticable on other colours than grey I guess...
i can also see some weird banding or whatever on a pure gray image, not sure how normal this is but ive noticed it with all of my 3 phones.
ghost image disappears for me within 2 seconds (very hard to see unless if you look at the screen hard), definitely not a problem, and wont be killing myself for this or even consider it a hardware issue.
i also facing a same problem as u guys, now waiting for service centre to replace my lcd.
This ghosting issue seems to happen with all phones, very visible when your using the keyboard and you drop down the notification tray, then it goes away after a couple of seconds.
Two issues here. First off, search the forum for burn in, its already been posted.
Two issues, the temporary burn in is new to the galaxy s2 and seems to go away after a few seconds. But all Samsung amoled screens suffer permanent burn in of the status bar, click time, and anything else in a static place.
My nexus one has permanent burn in right now, both status bar and keyboard. Original galaxy s and others has this also.
The temporary burn in seems to be different and only on this new amoled plus display so far.

i did search the forum before i post. however. as far as i know . burn in screens are permenant. and the other threads talked about that. here i am talking about something that goes off after few seconds. something like either ghosting / or something about low memory / low resposne / low refresh rate of the screen. not a real butn in.
I've recently bought a Galaxy S2 from someone and didn't see the burn in until a few days ago.
Now I can't reach the guy to get my money back... the phone seems in perfect shape except for the burn in (status bar and some digital clock widget).
I've been trying every day now to run this app called Screen Burn-in Tools for an hour or so but nothing happens.
You can find the app on the Google Play.
Should I continue using this tool or this burn-in is permanent and there's nothing I can do about it?
I can't believe such a high end phone has such a poor life display... how can this be possible!?!? They should've stayed with the regular LCD or something.
It's too bad because I'm a fan of the OLED idea and technology, but unfortunately samsung owns too many patents for this technology to spread to other manufacturers as well. This is what happens when the damn corporations get their greedy hands on something great that can benefit the mankind!
Hi all ! I recently bought a Galaxy note and was really happy with it. But recently I was reading a mail in the inbuilt mail client (not gmail) and had the background color set as grey and I see a tiny white dead pixel in the bottom half of the screen. I then performed the screen test with the RGB colors from the service menu but in all three screens its not visible. Its visible only on grey backgrounds not even visible on black background. Can any body else test this and confirm !!!.
Instructions: Configure the mail client in the phone (if not already configured) and open any mail and set the background color to grey. Zoom the mail as far as possible so as to see only the background and not any mail text. and check the whole screen for any stuck pixels from a distance of about 5-7 inches.
Please Check the pic !!!
Hello,
Can you please take a picture by a camera or so, as i think it gonna be easier for people to help you and to see exactly what do you mean.
I ve added the PICTURE now !
I have the same. I was considering to return it but I see the pixel not often at all.
Only on certain background...
tried to use screen test...gray background but nothing...
can you still exchange it ? Just tell them it keeps rebooting when in the middle of calls...works fro me...
More user please comment?

Checked... slightly hue change on right side but no stuck or dead pixel...
Checked mine and don't have any dead pixels or tint/hue problems. Screen seems perfect so far *knocks on wood*. HK white version of the phone.
Check to make sure your dead white pixel doesn't move when you scroll the gray background. I saw something that I thought looked just like yours when I opened up Pandora for the first time because it has a gray background when your entering your login info but I noticed when I scrolled up and down the tiny white pixel was moving as well and was completely gone when I scrolled it off the screen.

Suggest you return it. It should have at least one year's worth of Samsung warranty and depending on how you bought the phone (outright or through a carrier contract) they might be more generous as well.
And also mention that you bought this device for the screen and have a sharp eye for screen defects (because you are creative with the S-Pen? Hah!) and they may be more willing to offer an exchange or repair.
By the way it may also depend on which country you're in...
I got such a problem either.My phone had one dead pixel which is always black.And that happaned almost in 10 days after I've bought it.
I know it has 2 years of factory warranty and contacted with service.One of the technicians are a friend of mine and he told us not to give it to the service for just one dead pixel.One pixel is off the warranty until 5 and even it is 5 and the services agrees to change the panel,the phone couldn't be assembled as good as it used to be.So I decided not the see the dead pixel.
I have same issue
there is a reversed color pixel in my galaxy note display
it's visible in most background colors and just invisible in red and black back color.
this pixel is red in most times.
mines blue top right corner and you cab only see it when your screen goes in sleep mode

Try rapidly changing colors on screen it helps the stuck pixel to come back to life if it's really a stuck pixel. Never get only your screen replaced it's real bad, most of them don't fit the screen proper, dust gets in and it'll irritate you more than the current stuck pixel. Get the phone completely replaced if you can. 1 stuck pixel is mostly ignored under warranty terms, but give it a try
I have yotaphone 2 from tinydeal germany. (I think they flash the ROM to change the language.)
The phone worked fine at first but now the e screen on the back is doing strange things, leaving images of previous pages showing through the current page. This means, for example, on the clock face the clock is faint on a grey background and as the fingers move they leave a black after-image. Pages that should be black look speckled grey. Any suggestions for cause and a fix?
Unfortunately this is how (older) EPD screens work. When updated they somtimes leave a ghost image behind. To eliminate this the screen needs to be flashed white/black/white before redrawing and with the low refresh frequency of EPD this results in a very flickering image. So there is nothing wrong with your screen, this is just how EPD screens work. See also here https://en.wikipedia.org/wiki/Electronic_paper#Disadvantages
Thanks, but this ghosting or layered imaging is much more severe. I know someone else with the same phone where black is black and whilst there is very slight ghosting of things like clock fingers it is nothing like this current phone. The phone was fine when we got it, and the layered/grey imaging has started without me doing anything. I only mentioned flashing of the ROM because Tinydeal have told me that that is what they do to change the language on these phones.
So from the Wikipedia entry and your comments I now assume that the phone should automatically flash black/white between page changes but it isn't doing it.
The ghost images don't appear if you load something like chess or sudoko onto the rear display but appear again as soon as the regular Yotapanel or Yotacover is used.
I have the same problem, but only when the white theme in the Yotahub is turned off (so the dark theme is active) or when I use the Yota Mirror. The ghosting is terrible. When I use the white theme, it looks like it should look. I am not aware of any changes I made to my phone yesterday, but in the afternoon this problem started.
Does someone know how to check if the screen is flashing/refreshing correctly and if not, how to repair this?
Update: when I put a completely black screen on the back, it is spotty. The black is not black, but dark grey, and there are many lighter spots on the screen.
Update 2: the white theme has this problem too, but less visible. The white starts as real white, but because of ghosting becomes slightly grey. With black it is much more noticeable, because black does start as dark grey.
Well this may only turn out to be a temporary fix but I went through the Yotapanel pages repeatedly and very rapidly using the bottom of the page buttons.
I got all sorts of shades of grey and multiple overlying images but then the phone suddenly showed a clear black and white page with clock.
Ringing the phone from another phone produced a clear missed call message on the back of the phone and then after a minute the clear black and white clock page came back. I am leavng the phone without looking at all the othe Yotapanels or the Yotacover for the moment in the hope that something just got out of phase in the software and the phone might now settle down to correct operation again.
I have the same problem. It has started a few days ago and it gets worse every day.
Unfrtunately the problem has returned on my phone although I was able to get back to a black screen with the clock after three page changes using the bottom left arrow. This time a missed call message came up very clearly on the back of the phone but after the missed call message cleared the whole of the back of the phone was speckled grey with a very faint clock image. One question though: is this just the phones from Tinydeal where they have apparently flashed the ROM, or is it all phones?

That's the app for Nook ereader to refresh its screen and get rid of ghosting. Works also on Yotaphone.
What always works for me to clear the screen when the ghosting annoys me is to switch to Android on the EPD screen (by holding the circle button and choosing the left option) and switch back right away using the same procedure. This always leaves me with a clean black back.
Thanks Keeper and VirtualL.
Tinydeal asked me to upload a video to demonstrate the fault, and no sooner than they did that the phone started behaving normally again!
So if it goes again the first thing I will try is that page sequence, and if it fails the App.
I have to say that these are really fantastic phones. I think that a lot of original reviewers completely overlooked the basic issue of not being able to see a phone screen in bright sunlight, but that the yotaphone overcomes this problem.
Resolved by switching the back to front screen views a couple of times. Getting the front screen to mirror on the back seems to give that hard black and white interscreen flash that clears previous images.

I don't know if you already use it but this widget makes it very easy to switch between mirror and back. Just one click on the widget.

Last week, I got a chinese version (YD206) through GearBest. I had the same problem what you mentioned. (Black was always Grey and was never black and lot of ghosting). Until yesterday, I used to think that's how the e-Ink display works so I was using White theme all the time.
After seeing your post, I tried using Nook cleaner software and it did not help. Then, I removed the screen protector which the phone came with. For the next 1 hour, I did not see any difference. I left it thinking it could be ROM issue.
But, after few hours, I noticed everything became normal. Now, the e-ink screen looks goergeous in BLACK.

This issue keeps coming back and I am not able to find a guaranteed solution to this.
Like you described, activating and deactivating Yota Mirror in quick succession clears the ghosting and makes the screen BLACK. At other times, it does not work at all.
I even try swapping to different Yota Panels, but it is a hit and miss. Is this issue specific to Chinese version of YD206?
How to solve this issue permanently?
If not possible, is there any known step which I can do to clear the ghosting?

Hey Yotaphone Users!
I finally have a solution for this problem, that I received from the Yota Phone Support:
"If you see that ghosting is amplified, try to do some steps. Try to discharge the phone completely. Then leave it discharged for long periods of time, f.e. overnight. Then charge the phone to 100%."
For me that worked perfectly!
For me the discharge-recharge didn't work at all.
Discharged untill it switched off. Turned it on again untill switched off, untill phone wouldn't start up again. So: battery was flat.
What happened was: EPD turned black. Yohoo! Happy!
But: after one night discharged, i put it on charger again. Screen switched on, and ghosting was immediately back.
Disappointed. Very disappointed.
Anyone has a different solution?

Sad to hear that.
Did you remove the screen protector from the back side as in the post #14 the user said that after removing the epd screen became normal black again?
Has anyone heard and try heating with hairdryer the EPD screen for 2 minutes (not too hot) to eliminate ghosting?
Does anyone know how to solve screen burn-in issue? I didn't have this issue when I purchased the handset. It started all of a sudden. And now no matter what ROM and what android version I'm on, I always see the shadow of last used app (even if I keep the app open for 2 minutes). I am using Gold varient (64GB) handset.

From other threads there are two screen types and they appear to have moved to a new screen type that is less likely to burn, if you can, get the screen changed under warranty. The new screens are not quite as warm (more white). I have the new screen type and am happy with the colour.
I dont know if its the same, but i had a similar issue, where recent Apps that i used for some minutes (e.g. Whatsapp) slightly burned a shadow into my home screen.
I solved it by changing the 3 RGB values from 100% to 95% at Settings - Display - LiveDisplay - Color calibration (then restart phone).
