Brightness fluctuates in low light conditions - Nokia Lumia 920

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?

[Q] Screen Flickering - Black lines?

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...

CM7 Screen Dim Levels

I've done a search and it produced no results at least nothing relevant.
I'm wondering what people are using for their custom Light Levels in CM7.
Auto typically, but in my office I find it too dark... so I use 40%. I've got brightness (all of them) in the notification dropdown.... removed bluetooth and gps (pointless).
I have not done any of the screen rendering...
That's the same issue that I've had as well. I suppose it's partially due to my eyes being so accustom to the bright colors from the standard 2.2 ROMs. I'll look at tweaking it a bit. I don't mind the screen not being as bright as it was before, but it stays rather dim and becomes slightly hard to read at times.

[Q] LED Brightness Decreased after JB

Hi. 2-3 days before I did a Jelly Bean 4.1.1 update to my S3 from kies. (My country has DLJ1 release of JB). After the update i noticed some LED problem. When plugged my phone to plug, i noticed that my LED's Brightness has decreased (the red one, while plugged in). I plug out and plug in lots of times and only few of them shows bright LED. Also these bright LEDs loose it brightness again in 1-2 mins.
I tried the LED on notifications also. The same problem occurs again. Most of times the brightness is low from its usual.
Firstly i though it was a hardware problem and open test of my s3 from *#0*# and test my LEDs lots of time. In "EVERY" of the test, the LEDs are bright as sun and bright as usual before. So i start thinking that is a software/firmware problem.
Note: I also read a comment in another forum, someone also complain about this issue on "Charging Battery problem on JB.
So is this problem is usual and known or what. Do you know the reason and solution. How can i fix it? Thank you for your replies...
This is surely a widespread problem, I've found it too. As soon as I flashed official JB, I noticed the LED wasn't as bright. I suppose it's not a serious problem, but it isn't right.
Hi,
Happens the same here, with DLIJ4 ROM.
[]'s
Only affects the red charging notification and is a feature, not a problem. Less glare.
You make it sound like the end of the world... how sad.
Firstly i though like that but: If it is a feature why i can see very bright red LED while charging sometimes. As I said before, 90% times the brightness is low. However also as i said before in few times I saw bright red LED after a moment its gone again. If it is feature, is it normal ?
Also this happens in blue (notification) LED sometimes..
So i dont think as it is feature...
Not seen it on other colours, red is always dimmer than it was on ICS. I recall seeing somewhere that it was deliberate...
This is a feture. The LED brightness is now regulated automatically, depending on surrounding light.
I also tried in very dark room and also tried in under the lamp. But brigthness of LED is not change anyway I dont understand this ...
It seems that the surrounding light level is checked only when the charger is plugged-in and then in rather long interval.

For anyone interested, some info about screen flickering issue.

Seems that a lot of people complain about this bug/glitch. It mostly happens with this device, specific to some carrier like s5 t mobile etc. Mostly what people face is flickering with a green/yellow nuance that covers at least half of the screen, and that happens when you set screen brightness on minimum. Some other ( like me ) also get the flickering while turning the screen on or off. So I started doing some searches over the web, and tried all the 'fixes' possible. Sadly to me nothing worked. Some of these 'fixes' are :
Turning off auto brightness.
Turning off adaptive display.
Turning off screen overlay ( found on developer settings )
Also other strange ones like removing your sd card etc. Few people say that these worked for them, but for me it didn't.
I tried booting on safe mode, and the problem was still there. I also flashed official 5.0 and the same. So the only thing left was to blame the hardware. But I was sceptical about this since the problem is not persistive, sometimes it happens, sometimes not. Sometimes it happens on small scale, sometimes it is worse. Also a lot of people say that their devices were working fine and the problem started after marshmallow update. A certain person on an online forum claims that he/ she spoke with samsung officials and they are aware about this problem and working on an update to fix this. Does this mean it is not physical problem but just a software glitch ? Hard to say, I sent my phone to different local repair shop and they say it is screen physical problem. But maybe they just want to scam me and take money ( new screen costs too much )
After going through all these, I just got the idea to try and flash an older firmware, like kitkat. And to my surprise, on official kitkat rom it still does the problem, but FAR less.
So TLDR if you have this glitch and gave up on all the 'fixes' you found online, try flashing kitkat, it might work for you even if it's not a permanent fix.
I'm sorry to bump this topic being that it seems dead. However after my own research and now my second S5 from T-Mobile. I'm at the same point as you. My research states that it's more of an AMOLED screen issue, which after a factory reset and flash of older ROM and such does make sense. However, at the same time it could be an actual issue with the screen.
It's definitely a hardware issue in my case-cold temperatures exacerbate it ie-I have no flicker issues in the summer, but get flicker issues in the winter if my phone cool's down to the 60s. The flicker goes away if I heat the screen.
It seems the lower the temp, the more wattage (brightness) is required for the display matrix to function; insufficient wattage/heat when the screen is activated, and the matrix collapses. This is why it autobrightness tends causes issues when it provides power below threshold for matrix stability.
Easiest legitimate econimical fix is ordering a replacement screen, if you have reaervations about yiur shop doing it, it's a very easy/cheap/simple process to do yourself and plenty of how to YouTube videos.
okay, I will solve this issue for yall. I have an s5 g900t that had the screen flicker issue and also when temps are cold, the screen would blank out till I warmed the screen. I fixed this issue after a year of having the issue. a temp fix which can damage the device was found by accident when I went to change out a broken rear cam. heating the screen with a heat gun during surgery fixed the issue for a while then the symptoms came back. after much much research and testing, I found the amoled screen was the culprit. I ordered a new screen and replaced it. no more issues. I took the old screen and replaced it to my other s5 which is for testing only and the screen flickered under low light and would not come on when cold. so, if you have a screen that is flickering in low light and/or wont come on during cold, its your screen. replace it and fixed. how long the new screen will last? well 2 years later no problems, yet.
FYI, AMOLED screens are notorious for this issue and the manufacture is well aware.

Screen getting purple blotches

So I know this is a pretty common issue with this phone, but all was good for me until I was playing roblox with my daughter for an extended period and the phone got slightly hot. Now every time the phone gets even slightly warm the corners and notch, as well as anything on the screen, will repeat down the screen several times in a weird purple colour and the left edge has a green tint. I'm assuming this is a hardware fault and judging from the forums it is getting worse by the day (more users experiencing it). I tried contacting motorola but they are not getting back to me. Has anyone on here had this happen and if so how did you get it fixed/contact motorola?
Same here, it was good for a couple of weeks. A few nights ago I observed a green cast when adaptive brightness was on and the brightness was set to low. Today the purple artifacts appeared. now they are gone again.
I read that motorola has been trying to fix this with software and is stating that this is not a hardware issue.
disappointing though.
