so I returned my sgs2 today and got a new one (old one had scratches). Now it seems to me that there is some flickering with black lines (very faded) on certain brightess settings on mainly white sites using a browser.
I noticed the flickering appears around 16% - 19% brightness settings (using "brightness level" from the market).
This flickering only appears only if "auto adjust screen power" is NOT selected, same brightness with it activated shows no flickering.
Also last but not least if plugged in with USB cable the flickering stops as well.
Can anyone re-produce this flickering?
1. Download "brightness level" from market, go between 16% - 19% (try step by step), with me its strongest at 17%.
2. Ensure "auto adjust screen power" is deactivated under Settings>Display
3. Open Internet and just look at a mostly white page
4. Ensure USB is not connected.
Can you see some slight flickering? Lots of lines across the screen?
Wonder if its just me, might go back and return this one tomorrow then
I assume no one suffers from this issue?

No flickering.
I get black/dim horizontal lines flickering on the display at low brightness regardless of my "auto adjust screen power" setting. I'd describe it more as a shimmering of the screen. It's very distracting - I first noticed it whilst trying out the Kindle app and it made it very difficult reading the text.
I believe it's down to interference with some radio component of the phone. I've searched various forums and haven't come across many mentions of this so maybe it's a bad batch and I'm considering returning mine. It's frustratingly variable so I hope I can demonstrate the fault in store...
I'm wondering if the increase in brightness just masks the effect rather than eliminating it. At lower brightness settings, any local differences in brightness are going to be more noticeable.

have you noticed any change at certain battery levels?? Like if the battery was at 90% its easily noticeable, once its like below 70% I'm not able to re-produce it, no matter what I try down to 0%.
So maybe since it seems to be only from 90% - 70%, it could be to do with the current/voltage at certain brightness levels with white background...very unique problem it seems..I'm thinking of going to the o2 store but I most likely wont be able to re-produce it then and there so will they still exchange it? hmmm lets see..

I'll note down what the battery power levels are over the next week or so.
I went into the O2 store after work and reproducing the effect was indeed difficult. I had it showing the effect in the shopping centre whilst sitting down at a bench. I had it showing the effect whilst in the queue to wait for an O2 staff member. Fifteen minutes later, once I'd got to talking to the staff, it worked fine. All I could do was explain the problem and ask if anyone else had reported it. They advised I "kept an eye on it over the next couple of weeks".
Really frustrating. I'd entertain the possibility that my eyes are faulty but I've shown the effect to someone else and they agreed it was distracting.

Hi,
I was not able to reproduce it using your directions, but I have to say that I also noticed horizontal lines flickering on white.
I tried to reproduce it but I can't find out what it is related to.
So it's doig it just in random fashion

does it flicker with auto brightness on? You might want to download an app like "brightness level" and set it to different settings to see when/where it flickers...mine usually flickered at 17% screenbrightness when battery was at 70 - 90%

Yes I did download it and followed yur directions to try to repruce it. But I could not. I set then brightness to various level from 100% down to 0, but no luck. I have to try now when battery is at that level. Then it could be some kind of intereference. Lines I noticed on mine are very subtle and close about 1 mm
Ok, confirmed: 92% battery, brightness 17% on white or close to white screen color, there are horizontal lines like some itnerefernce/noise. Annoying
Samsung galaxy S2 screen flickering
I also have the same screen flickering problem.
it happens when the battery level is around 87-91%
Any soulution?
same here
black lines around text on white background. It disappears after a while, but is really annoying. I suppose the only solution is to change the phone?
sorry guys to hear u got the same problem....I never found a resolution to it apart from returning it to the store....once I managed to reproduce the issue infront of the manager he swapped the phone straight away.
If you got the same issue make sure you get to the store with the battery level and brightness level that shows it up, ask to go into a dark area to show it properly.
First o2 store I went to the guy refused to look at it properly and as it was light outside he couldnt see it anyways. Second o2 store I went to, the manager went downstairs with me and turned off the lights to see the flickering because it shows only on low brightness so make sure you take that into consideration when in a bright/well-lit store.
i have the same problem, it, but it only appears when "auto adjust screen power" is on. Its really a shame! Only way to fix it is to change the phone?
same here. flickers at low brightness with battery under 90%. called samsung hotline. the problem was new to them and the only idea they had was resetting the phone. tried it but unsurprisingly its no help. galaxy s2 could be great but it has just too many annoying hardware flaws
Same problem
Well I noticed this on my SGS 1 !! ... when I have PACKET DATA turned on this flickering starts. It starts really hard when i have this function turned on, but when i disable it there's nothing...
Noticed same problem on SG2 bought in Sweden
Realise this is an older topic but i have recently noticed this issue in low light with Auto On. Battery level at 85 percent. For those that had their phones replaced did the issue continue? Has anyone seen this with the yellow tint also?
Noticing this issue as well on Villain ROM 2.4. Auto brightness enabled and 90% battery.
*Edit* Just did a CWM restore to stock rooted and the flickering seems to have gone. 85% battery, auto brightness enabled.
phone swapped... problem kept
i got my phone replaced 2 months ago and was very happy with the new one since it had no screen flicker... until now. so my current sgs 2 now also suffers from screen flicker and my only options are to send it to samsung and hope to get a replacement or to live with it. and since im beginning to think that this might be a general problem i tend to keep it. although i have to admit that i dont like my sgs2 as much as i did before...
I have a 920 that came preinstalled with Portico ROM version (I bought it about two weeks ago). It's a great phone and improvement over my LM800.
One thing is bothering me, though. In low-light conditions the screen brightness keeps changing from normal and readable to hardly readable. It's like the light sensor is constantly flipping between two states. I read some report on the internet that I am not the only one.
Some suggested that it could be fixed by turning the phone of and turning it on in complete darkness and unlock the screen. That sounded a bit strange, since the screen will emit a lot of light during the boot process, but I tried it anyway... didn't work.
Anyone else experiencing this issue?
I have smart stay and auto brightness turned off, yet my screen still seems to dim and brighten on its own sometimes.
Also, when the lights on the two soft/touch keys goes out, shoulsnt pushing the middle button make them light back up? Cause I was pretty sure it did at one point but it doesnt do it anymore, but I could just be tripping and remembering it wrong so I wanted to check

And as of today, the softkeys started not lighting back up when dimmed, after I press one or touch the screen. I have to turn my screen off and back on to get them to light back up. Doesnt do it all the time but its annoying. I just got this phone exactly a week ago and so I wanna figure this out so I can exchange it for a new one if I need to, before the 14day return policy is up

Sounds like the proximity sensor is acting up. If you are within the 14 day period you can exchange for a brand new phone.
My phone also has some weird dimming issues. The most prominent issue I've seen concerns the stock Gallery app (http://forum.xda-developers.com/showthread.php?t=2421173), but I do see strange dimming occuring at random.
My phone does some other wierd **** too so im just gonna exchange it for a new one today. Its only a week old so it shouldnt be having problems already. I paid a decent price for this phone, so I dont wanna get stuck with a faulty one

I think I figured out the screen dimming issue. I didnt know there was am auto control for the display tone. I turned that off and so far the screen hasnt dimmed at all

Oh and turn off Auto Adapt mode in the display>screen mode, options.

Hi, a few days ago I've updated my Z5C to the last firmware (32.0.A.6.152). Everything went fine, except for this problem with contrast or gamma right after unlocking the screen. It goes all the way up, stays crazy for a few seconds and then goes normal. It happens only if Adaptive brightness is turned on.
I really have no idea what is going on, but I've seen around the forum that others had the same issue with Z3C, but no solutions were given.
Any idea of what could it be?
Thank you.
I have same problem. So I use 3rd party application in google play. (like lux auto brightness). Then the problem solved.. (My eng is not good. I hope you will understand.)
Same problem here. The problem always had been here, since the first firmware. Wait and see.
Same here, I also noticed some extreme oversharpening (LG G3 style) while it does that.
I can't reproduce this issue because sometimes it doesn't do anything and sometimes it does.
This was a known issue on the z3c since it surfaced never got fixed, I believe Sony acknowledged this issue too.
If we indeed have the exact same panel in the z5c then its almost understandable why it is occuring on the z5c.
However I have not yet noticed this issue on my z5c (adaptive brightness turned off.)
It is caused by adaptive brightness. Yeah i had it before on my z3c as well. Only solution was to turn auto brightness off
How could it be possible that Sony still has to fix this? I mean, adaptive brightness is quite useful, what are they waiting for?
Yep.
For now turn it off, as that's the work around for now buddy
Same problem here, it is really annoying since adaptative brightness is very useful... don't want to change the brightess manually 5 times a day ...
Same here with z5 UK
Same here too. Z5c spain

Same...I thought it was some app going crazy, lucky I found this thread. Z5C HK on the latest version.
Same problem here aswell, but i also noticed i dont know about you, when i scroll text its getting blurish and greenish dont know really how to explain, if it problem with something in software or screen panel?
I opened this topic weeks ago, uploaded a "bug report" to a Sony forum member (a few weeks after). And he contacted the development team. After that he told me that it will be fixed in Marshmallow update.

Display is so dim even when the brightness is kept at full and i dont know how this happenned and someone tell me the way to solve this problem ! Screen is very dim even when i adjusted the brightness level at max and i even tried formatting phone but the issue remained same
Hi this also just happened to me. Image is working but no brightness in screen except some bright ess in top right corner. Phone overheated a couple kf times and shutdown after this initially happened and consumed 2 full batter chages in minutes. Now the heat and battery problem is gone but screen still dark. Any ideas
Hi guys!
I`m having the very same problem. Back light of the main screen is gone, and it doesn`t matter how I adjust it, it is always dark.
Have you guys solved your problem already? Any ideas?

Having the same issue as of yesterday, been Googling possible reasons and it seems the 'backlight controller' has malfunctioned and the entire screen needs replacing (allegedly). Considering a new screen costs almost as much as the V10 itself on ebay these days I'm going to be trying to take mine apart to see if an easier fix is possible, it is more than likely there isn't, but I at least have to try. Let me know if any of you guys have any luck in repairing your phones

Update: Having replaced the screen with a new replacement screen, I am still having the same issue, indicating an issue with either the mainboard and/or the chipset. Can't really go much further with this it would seem so unfortunately I don't think the issue has any DIY fix...
Sorry guys... RIP my V10

I have Same problem,, Any solution ? please help me
My LG70 just did this for a few minutes
My LG70 just did this for a few minutes. Scared me to think my phone was dying. Restarted, still the same. While I was googling it, the screen came back on. Hope it stays that way. Really strange to take it out of my pocket and only have the screen lit in the upper right hand corner. I hope this wasn't a preview of things to come. Love this phone and want it to last!
