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.

Hello everyone,
A few days ago, my phone screen became very bright. Not happen immediately but gradually, first for a few hours, then recovered, then for a full day, followed by a shorter recovery and so and so. Right now is from two days in this condition. Besides the fact that all the colors are very fade, there are some aberrations in the gray area (green and purple instead of dark grey), as can be seen from the photos attached.
In this time I did a factory reset and an upgrade to Mango, but the problem persisted, so it's probably not software.
So, has anyone any idea what could be the problem? I think it's not the screen, but maybe the connector or the video card? Has this happened to someone else?
Thanks in advance for your help.
PS: As for the good side, I have an excellent day view of my screen, no matter how sunny it is ouside )

The AMOLED screen gargled. Get it repaired / replaced at a service center. Happened to me on the SGS.
Today my hd2 has shown some strange color issues: Grey / Transparent black causes a grin/yellow tint. I did the usual troubleshooting (soft and hard reset) but it did not help. I also read some old threads about it saying that I should flex the screen to make it go away (http://forum.xda-developers.com/sho...m.xda-developers.com/showthread.php?t=1003265). I tried that without luck though I'm not sure if I "flexed" the screen enough but I'm afraid of breaking it.
Anyone an idea what caused this problem? I did drop the phone a few times over the years, however, today, when it all started, not. Secondly, I can't really think of a broken screen as it seems that only a specific grey is tinted yellow/green (the grey whatsapp uses for their contact without photos and the grey used for the keyboard when you eneter your pin.
Any help is really appriciated... Don't want to loose the king :crying: as this color issue makes really unconfortable.

EDIT: I'm on a european hd2 with the latest Pdaimatejam WP7 rom (v8.2) and I even tried to reflash the rom... Seems a hardware fault:crying:
Today morning the issue faded away without doing anything at all . Might be that the screen got somehow pressure causing some disorder of the fluid crystals and with time, they reordered themselves...
So My S5 worked great for 2 months or so but then the screen started flickering at very low brightness. As time passed the flickers increased and now whenever the brightness goes below half, the screen shows yellow flickers. That's not even the biggest problem, when i lock my phone and then press the lock/home button to turn on the screen, it shows a flash on the screen and goes dark again. This takes around 15-20 tries everytime almost (sometimes even A LOT more) to turn back on.
There was no water or fall damage.
I've tried factory/hard resetting, disabling hardware acceleration, disabling google chrome (worked for some people on the internet) still not solved.
I don't have warranty, and i'm willing to pay for some repairs but can someone help me out here and tell me where exactly is the problem? Cause i really don't want to pay for a new LCD. It's kinda costly. Thank You

I have the exact same problem but only at the bottom of the screen...I am sure is not a software problem because I tried everything (from reinstaling soft with odin from4.4 to 5, with kies, to CM12/13). If you find which is the hardware please let me know.
Thank you. I also don't have warranty and i got this flicker from November.

I also have this problem. I did bring my S5 for repair under warranty (but have knox tripped) and they REFUSED to repair it,because they think the problem is caused by ME. I did go to a lawyer, and I am gonna sue them. Will update you if I have new info. I am sure it is NOT a Software problem caused by the user,I also tried changing OS,reinstalling Stock,nothing solved my problem.
any update dear as i have the same problem but for me it happened when there was low light means in darkness so when i un tick the auto brightness it will be okay no more flickering issue
Same here. Flickers, stays black. Tho I can fiddle around and it will pick up touches, and have gotten it to reboot.
It will work fine charging. Batt icon works. It only seems to be an issue while its running.
Happens on stock and cyanogen 14.
I have noticed it seems to happen more when cold.
Same problem here on cyanogen 13.0, tried factory reset to no avail. I'm about to try flashing another ROM, just need to figure ou what.
Just done wiping and reinstalling new ROM, bumped up to 7.1 and the problem is still the same.
- Screen has difficulty turning and flickers when the brightness setting is low.
I guess it must be a hardware issue.
My fix for the moment is to disable automatic brightness and never set the brightness too low, so as to avoid have trouble turning on the screen.
Same here. It's a typical problem.
Same...

I have a feeling that the problem is caused by overheating when charging. I fell asleep and woke up with the phone underneath me, it was blazing hot. It has been doing what the rest of you describe since then.
I am not 100% sure, but I've heard that it's due to the low voltage (brightness) being applied to the screen which is causing the flickering. Unsure why it's only the bottom half (Also happens on mine).
A work around for this is to install a screen-dimmer such as Darker, set the brightness on your phone to be above the flickering amount, then use Darker (or whatever app you use) to lower the brightness down.
Because Darker (or whatever app you use), is a filter, it won't change the voltage, thus no flickering.
do any of you have the always on feature enabled on the screen?
This problem is soooooooo often. Internet full of it.
Is AMOLED designed only to work for 2 years???
Anyone any information about that?
try downgrade firmware back to Android 4.0
Edit: nevermind, this didn't work
Perhaps AMOLED life time is short.
I will buy a LCD display next.
Same here only below the screen. It happened last month

How can we up to low brightness voltage? Is this possible?
It happens only at low temperatures. When you make your phone warmer, the flickering at low brightness stops.
Has anyone tried to check if some kind of cleaning the flex connector helps? I'm thinking about buying LCD sticker and give it a try.
I have the exact same problem and its related to temperature, I never face this problem in the summer.

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?
