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.

Suddenly the screen of my "samsung galaxy's" seens to lost resolution, looks blurred and weak colors.
It looks like when changing the resolution of a monitor to display fewer colors.
Please can any good soul help me?
completing information
I also noticed that the button used to end the call, it seems
orange and not red as it should.
I restored the settings but not solved the problem. I'll try to flash the rom again to see if it works, but seems to be a hardware problem that appeared out of nowhere

That do not sound so good. Looks like a hardware failure to me. Do you have the screen on full brightness all the time? Perhaps you could try changing display density in build.prop and reboot. How long do you have your sgs?

Galaxy S screen problem fault
I am having the same problem. Vodafone Australia stock.
The screen has lost its clarity.
Actually, it appears as though every 2nd horizontal line has been lost - this is quite evident when you scroll through a list that has dividing lines (Eg. Scroll through settings - the separator lines alternate visibly as you scroll).
I've had the i9000 for just under 4 weeks and this fault occurred without any reason (not dropped, no water damage, not exposed to heat, etc). The phone was fine one minute and then the next, it became blurry.
The colours all look flat, the background is no longer crisp black, it is light black/grey as if the LCD that had its brightness settings turned up too high.
Also, tried upgrading Android to 2.2 (from 2.1) and that didn't help. This fault appears to be a hardware fault - you can see the loss of resolution when the Galaxy S logo appears when you first turn the phone on (before Android boots). Look at any curved text/lines and you will see that it appears with jagged lines.
Don't waste your time doing the factory reset, upgrades, etc... It is a hardware fault. I spent a bit of time running the screen through the LCD tests " *#*#0*#*#* " and downloading DPI checkers, etc.. The LCD test shows the solid Red, Green and Blue are ok, as was the dimming test.
The image looks grainy as if it was displayed in the wrong or low resolution. It looks like an old school CRT screen at VGA resolution - almost pixelated.
I have installed the Aries bootloader and the small font text displayed also looks grainy and very hard to read.
Have a look at the two images I've attached.
Real shame, I was starting to get attached to this phone.

First step would be to backup and do a factory reset for any major problem .

I already tried that and it did not help.

Don't waste your time. If you got warranty, you are going to get a new Screen or perhaps a new phone. Go for it.

Did you changed kernel? which kernel are you on?
I had a similar experience (not so bad) when trying some kernel with sharpness and color fixes.
You could try flashing hardcore's speedmod k13c Kernel, it also has some sharpness and color fixes but his work very good.
i don't have thi problem
I have the same problem, just purchased a i9000 four days ago, and it fail after 30 minutes of use .
It si very strange, because if i zoom a image, it will also enlarge the banding gradients (like if the image was low quality)
THe problem only appears wirh dark colors, strong colores dont have any problems.
this sounds like a display problem

Hello everyone,
I would like who claims to have a perfect display (as well as all the others) to Try this test:
- Completely dark room and eyes accustomed to the darkness for a few minutes
- Completely black screen (like the one in the test screen by typing * # * # 0, but also any settings menu screen that has not written)
- Minimum brightness (but can be seen even at maximum brightness).
If there are, you should see black spots darker than the background black.
I have them and at night are quite annoying.
I need to figure out if it is a problem of all devices or only of some (in this case tomorrow i will apply for replacement).
Please, you who are reading now, don't leave without doing this little test, it only takes 5 minutes
Thanks: D
Are you nuts? While this may be new to you, there's a 200+ thread already going on this that was started in May. We don't need another 200 pages of "yes it is," "no it isn't." The short answer is yes, there's banding on the 1/4 left side of the display but for most people it can only be seen in a dark room, at 10% brightness, on a grey background, and by taking a pic of the phone. It's been that way since the phone launched and at this point choices are: 1) live with it, 2) return or sell the phone.

Apparently some don't have this issue, as you can see in the first listed thread. Difficult to confirm or not of course, I know mine does have smears/smudges/lines and no it is not grease.
@Barry don't think he is talking about the yellowish tint.
You read this on another thread and started a new one?
I saw the exact same thing on a post yesterday..

Dude, If I may :
before asking us to show the perfect screen (which does not exist actually), please consults an eye specialist and then, come back to XDA.

If you can ever see what you describe under normal use then it is a problem. If you can't see it under normal conditions then you are simply looking for problems and it's nothing to worry about. It's just what SAMOLED screens look like when they're "off", but not off.
I see this every day when I go to bed as my phone is also used as a night clock.
I have the font set to a very low brightness font, except for me I see lighter splotches on an otherwise black background.
I went through 4 SGS2's trying to find one that didn't have it. They all did. Bad batch I guess.
It wasn't a major deal for me so I just live with it.
It's a shame but meh. otherwise this phone is fantastic.
Recently, my mom's tf developed a weird screen effect, everything turns this reddish orange color. Not all pixels, but some of them, like a shading. The only thing she said that changed was that her weather wall-paper updated, but the issue turns up on all screens. Help?
After looking around more, it appears as if it's mostly on picutres that the strange coloring appears.
Also, the TF is completely stock, with the latest update.
If you could post pictures that would be helpfull but most of these issues are caused by drops loosening the digitizer cable so you may have to send it in to get fixed
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?

I have the same problem with a GearBest YD206 running Android 4.4.3. Would updating the firmware change anything?
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?
Hello,
So my S7 edge got a replacement display due to being broken like 2 months ago. Today purple smudges started to appear, when I used the device for quite some time heavily and it got quite hot. They disappear when I change display mode or when brightness changes. But sometimes reappear. Is this a defective Display, should I get it replaced via warranty again?
Mine does the same thing, but it has never been repaired or suffered any kind of serious damage. It's not that annoying either.
Could it be some kind of factory defect?
When googling I found it clearly is a hardware display fault. As I had my display swapped by a third party mobile repair shop, they would be the ones to make accountable.
It only occurs at certain brightness settings, and not in all apps/states of display - mostly in those which are really bright like chrome browser without tab open, or dict.cc dictionary app.
I'll keep an eye on the issue and just demand warranty, as this display isn't even 2 months old now. They give 6 months of warranty on exchanged parts. So if it does not go away, I'll just get it replaced again.
It just occured today out of the blue, after flashing custom rom / flashing some stuff and constantly playing on the phone, and it became a bit hot.
It occurred exactly the same to me, after flashing a custom Rom. Now I can't remember which one, but it changed the screen's aspect ratio to simulate the S8's.
After that I flashed stock and the problem kept happening
But I don't think this can be caused by a custom rom... it's a hardware fault.
I hope so because I really wanna install a custom rom ;(
Google the issue - it happened a lot apparently and there is literally no connection to custom Roms - it's a defective Display. I did not have the issue anymore BTW.
I have to get back at this again. I recognized that I can Only see these smudges under certain conditions. I can not see them when I am inside. Only outside, and Only from specific angles - also dependant on screen brightness. When I cover the screen with my hand they disappear.
At first I thought it could also be some fault with the transparent protection skin I also applied one day before first noticing this purple screen problems. But the thing is - they move when scrolling, Only in a small portion of the screen but they go up and down.
The fact I can Only see them in daylight makes me wonder if it's got anything to do with the surrounding brightness sensor that does the automatic brightness and display mode for you.
I find it very strange that I can not provoke the issue indoors, also not if I set up brightness to max.
