Screen uncontrolled auto-dimming - Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl

Hi.
I recently noticed that the screen is performing some sort of auto-dimming when displaying content, just like Samsung TVs do on Dinamic Mode. This is not to be confused with auto-brightness, it's something completely different that happens at every brightness level and in every screen mode (Standard, Dinamic, Cinema, Adapt Display).
I first noticed this watching a TV show with subtitles. Whenever the subtitle kicked in, the screen will shift the luminosity of the image displayed, dulling it, resulting in washed out blacks and contrast. After the subtitles disappeared, the image was restored to its previous state. I thought it was app-related, but it happens everywhere. It even happens when displaying still pictures in gallery apps or using comic reading apps.
Cycle between this two images and check it out. Maybe subtle, but it's annoying as hell. I'm on 5.1.1 and I don't know what may be causing this, but I can't recall it happened in KitKat.
Any help will be appreciated.

Not sure if I notice this back on KitKat, but I believe this could possibly be a standard feature among IPS screen?
My VAIO Pro 11 laptop and my Xperia Z1 also experiences it, albeit only if the changes are total ie if the displayed colors cover the majority of the image for instance when changing from a black image to a white image, in which the screen will brighten a bit when more whites are displayed, and vice versa. So it's a more subtle change than what you are experiencing there. However I have not yet notice this on my Note 2014, maybe I wasn't attentive enough. Not really a major bother though.

Hi.
I have an standard IPS desktop monitor and it surely doesn't show this behavior. I have even calibrated it with a colorimeter and it works flawlessly within its specifications. Anyway, I don't recall the Note 2014 having an IPS screen but a simple LCD, but maybe I'm wrong.
I will later try and record a video, I hope I can capture the tablet performing the tweaks. I find it so annoying that I hope downgrading to KitKat will solve it, if there is not other way to fix it.

Here, I managed to capture on camera exactly what I see. Check it out:

I don't know what is causing this.

[Q] media link banding on tv

Hi guys
has anyone else experianced a flickering every now and then when using the media link accessory. It occurs every few seconds and caused the picture to bounce, with a usually green band on the bottom part of the screen. Ive started to use zoom to get rid of the banding on my tv - not ideal and the boucing is still there.
this is occuring on all my videos, using both mobo and gallery.
Ive got samsung plasma 50 inch tv, it also occurs on my 23inch led sammy and my 40inch sammy lcd (older tv). ive fiddled with my networks and cannot get rid of the problem, i think there maybe an issue with the firmware on the device but need other people to say they are also having this issue before i go to htc.
thanks guys

[Q] LiquidSmooth 3.2-2014-07-28, Videos mostly appear only in pink and green

Hello, I've been a member for a while and I can usually figure problems out on my own just by searching, but this is something I haven't seen anything on after some pretty extensive searching (unless I'm just searching wrong). When I try playing most videos, they play as normal, but all the colors are green. There is also a pink color, but it is stretched and doesn't seem to line up with the green portion of the video (which looks to have the proper ratio). This happens in the YouTube app, when I'm screen mirroring on my TV, and in YouTube via Chrome (but only when not in full screen).
Does anybody have experience with this or know why this might be happening? The videos were working before I installed this rom, and it's not this way for all videos, just most of them. Again, these are standard YouTube videos that I have no trouble playing on my computer or TV, and some videos will even display properly on my phone while I'm screen mirroring, but will be green/pink on the TV simultaneously.
I've also attached some pictures so you can see what I mean, since I'm not quite sure how to describe it.
Is this a known issue? Is there a fix for it?
EDIT: I've done some more searching around and found some people that have had similar issues, but on PC and not Android. It seems their fix is to disable hardware acceleration, but I don't see anything like that anywhere in the settings. Should I install a new kernel? Could that be part of the problem?
Edit2: I'm going to try flashing a new rom tonight to see if anything changes, will edit with any updates.
Flashed SlimKit yesterday, videos work like a charm now. Seems there may have been an issue with either the ROM or kernel I was using before. Mods, feel free to close/delete this.

[Q] AFTV2 Screen Brightness Changing by Itself

Hello, I've been noticing this weird issue since day one with my device. The screen will dim and brighten itself periodically through use. I have only noticed it while using amazon instant video, a few games, and occasionally netflix. I have not noticed any dimming/brightening while watching Kodi. My aftv2 is currently rooted, but I have noticed this since originally setting it up on stock, and all the way through 5.0-5.05 or whatever the current version is.
It basically looks like the screen dims itself a little bit or brightens back up and it is really annoying (at least to me, not sure the wife even notices). When it happens, it looks like when a phone dims itself automatically from a sensor. I have not seen anybody else mention this issue, and I am fairly certain I'm not insane (or at least not because of this).
FWIW, I am using fairly new LED samsung "smart" tv and the input i'm using for the aftv2 was previously used by a nexus player that i have since gotten rid of and never had any dimming issues with. I have had all sorts of other devices used on this tv's from pc's, gaming consoles, receivers, etc with no issue.
any ideas?

exposure / autofocus flickering

Very happy with the HTC 10, certainly with audio quality when recording live music.
Anyhow: I have a problem with recording video in dim light situations: the video (whole screen) flickers now and then.
In good light situations (outside daylight) the issue seems not to be there.
The flickering is already visible in the live preview during recording (but even worse: also in the final recording)
Note that when you switch to "photo mode", the flickering is not visible in the live preview.
I think the cause can be that de Auto exposure is switching too fast, or is interfering with something.
For a very short example clip see: (here you see the flickering is also visible in the final recording)
https://www.youtube.com/watch?v=2brDkD4Zjn8
This may look like an "artificial situation", but here also a real life situation (with nice live music )
https://www.youtube.com/watch?v=ujDZtrS0NXc
(flickering: second 1-3, second 15-18, second 38-41)
Firmware HTC 10:
1.95 / 1.95.401.3
Camera Version:
8.10.763406
Question is:
- Are any users experiencing this issue?
- Do you think this is a hardware issue? Or software?
- BTW: photo's look perfect, so I hope it is an issue that can be fixed.
- In daylight the flicker issue also seems not to be there
Tried so far:
- Deleted camera data / camera cache
- Cleaned the camera lens / autofocus lens
- Tried other camera apps (same issue), so if it's not a hardware issue, the issue is not in the camera app, but probably in the firmware.
Any ideas?
Update:
Maybe it can be related to 50 / 60 Hz interference ?
Also see: http://forum.xda-developers.com/htc-10/help/camera-flickering-video-recording-t3476842
Note: on my Mi5 I don't have this issue
BTW:
See this clip: Using 30fps video can create flickering artefacts in artificial light in PAL regions.
https://www.youtube.com/watch?v=KxBB8HmJB6A
Currently the HTC 10 indeed records in 30 fps (actually 29.97), so maybe that is the cause?
If this is the case, then this issue probably only affects users in Europe ?
-> Update: see comment below: flickering is can also be reproduced without electronic lights
- Update: can also reproduce the flickering without electronic lights, so the 50/60 Hz looks like a different issue.
- The flickering seems to happpen in low light situation, with backlight (from a window by example), where +/- 50% of the frame is in low-light and the other 50% has backlight
I get serious flickering both with photo and video if there is ANY light interference in low light situations.
Example being aiming camera sideways on our couch (so 90 degrees away from TV on far wall), low light as evening, the TV is enough to send my phone in to overload, its more or less impossible to get a photo or video due exposure and who knows what changing what seems like hundreds of times a second, drives me nuts I have given up trying to take shots in such situations.
Can put in pro mode, then the colours jump all over the place from that interfering light.
edit: just to add to this, the TV of course is changing colours / light constantly so I believe that is what makes my phone have a meltdown. If say the TV light is static the camera will stay static I believe with little to no issue.

Did you try if the problem is also there in other camera apps?
Try by example open camera.
In my situation the flickering is not gone, however, i did see that the "banding issue" is less in open camera, unfortunately it doesn't help against the flickering I experience.
BTW: what firmware are you on?
I have not tried another app, no
Can try that tonight though (8.21am in the morning now)

I also have made a topic with this issue. I've tried with Camera FV-5 which has the interference option to set 50/60 Hz and it makes no difference. With the TV i haven't any trouble making video/photo. No bands passing by.
The conditions are: environment with low illumination (the lower light the higher visible effect) and any source of electric light.

What is your firmware version ?
Still not clear to me if this is an software issue, or that we maybe have a device with a hardware issue.
This beacuse I don't see a lot of reports about this issue. If this would affect all users, I would expect more reports.
I have the same issues, combined with some dropped frames AND a weird panning effect (have a look at the HTC 10 Camera Thread).
You can check my videos here , here and here.
But, if you put the slider for the exposure all the way down, or lock AF/AE to a bright source, the flickering disappears, no matter if you pan from a bright to a dark area or not.

Neither to me if it's hardware or software. I have the 1.92.709.1 firmware of the 10h unlocked version.
Due to the variable conditions, i tend to think that is fixable via software update, but well, i don't know...
Hi, I've the Taiwanese version of HTC 10 and I can confirm this issue. It should be noted that D4v3 is right. If you lock AF/AE the flickering effect dissappear. Please long press over a light source until AF/AE block message appears. You'll see the problem is gone.
I guess the problem is firmware related because if it's a hardware issue why can we fix this blocking the AF/AE? I think it's related with how the firmware manages changes of lights.

I agree this looks like it could be fixed with software, but the fact that so few users report this issue, makes me think it is not affecting all users.
If it would affect all users I would expect a LOT of reports, since in fact recording in dim results in very poor quality.
@ Jadraker is saw your threat about a new update: 1.96.709.5 -> Does this update fix the issue?
It could be too that not all users uses the camera to record video in such low light circumstances. For example, I noted this issue when I read your post. It's probably that without reading the post I would never realized that flickering.
About the update I'll test the phone at night and I'll publish the result accordingly.

Unfortunately the flickering issue wasn't fixed with the update I received.

The question is if HTC is even aware of that. Don't know how to point this out to them, since it's really annoying and not just happening in low lit areas but also during daylight
It seems HTC 10 is not the only device with flickering issues while recording video. Please see: http://forum.xda-developers.com/galaxy-s7/help/samsung-s7-camera-flickering-t3337032
I don't know if it is the same problem but at least it's very similar, isn't it?

I could not find a lot examples on youtibe of the S7, but based on the text I would indeed think it is similar.
I also own a Xiaomi Mi5, and compared it with the HTC 10 in the exaxt same situation, the mi5 doesn't flicker at all, whilte the HTC 10 flickers.
It looks like the Mi5 is change the exposure more gradually.
I think there are 2 issues with the HTC10 camera:
1. Flickering caused by (eletronic) light in dim situation (scenario: +/-50% of surface dim +/- 50% of surface bright)
2. Issues when panning the camera
I find it still difficult to define an exact reproduction path.
But part of the problem also seems to be white / shiny surfaces, see this video: https://www.youtube.com/watch?v=7PZQYZvJ8lI

Question OP9 Pro Netflix unwatchable, darkness problem with HDR content (LE2123_11_C.62)?

Hi, first of all, I did all the googling, read reddit etc. so the following problem seems to be quite common, u find it a lot on the internet, but maybe I have not seen a possible fix yet...
So, I got the OP9 Pro yesterday, did all the updates, so iam on LE2123_11_C.62 EU right now. When I watch netflix, the dark / black colours, are so dark, I cant see anything. Video quality looks really, really bad, basically unwatchable. Brightness in the system and netflix settings obv highest possible lvl.
I tried the following:
- changed all the video/picture enhancement options in the settings menu, on/off, combinations, everything. Nothing helped.
- Restarted the phone, tried PIP, uninstalled the Netflix app via ADB (u cant uninstall it manually caus they put it as systems app...), reinstalled via play store
- turned off HW-Overly or so in developer settings, caus someone said this will fix it, it didnt.
I basically read 2h of reddit and whatever not threads, I tried so many possible fixxes, nothing helped.
The colours/blacks are so bad, I cant watch netflix at all, makes no sense. It seems to be a long term problem of this phone, caus u find people complaining abt this back from their OP 7. This is only a problem with the dark/black colours and probably HDR?
For a almost 1000€ Phone, this is just ridiclious... I come from a Poco x3 and even though that screen was garbage, at least it would play netflix content properly...
Maybe I missed smt and there is a fix for this?
Thx so much, if I dont find a way to fix it, this phone goes back to OP.
no idea what to tell you. i'm stock and rooted no issues. have u tried uninstalling netflix and reinstalling after a restart? if that persist try reinstalling your current or latest firmware. OP9 Pro is a great phone with a spectacular screen
Hello ,
I have exactly the same dark and yellowish image problem on netflix and amazon prime video.
it seems that the problem only occurs in hdr or high quality video. so I think that with the netflix 1 screen or 2 screens subscription there should not be the same problem.
indeed in the netfix settings if I lower the video quality (saving data) the image becomes much brighter.
I think there is really a big bug on hdr content, and what is more worrying is that the problem is still present in the oos13 beta despite the problem having been reported several times...
the problem seems to be known for a long time and still not corrected and affecting many users:

Is there a way to effectively resolve this issue?
Apparently not...I'm on one plus 8t on Android 13 and the black section are simply unwatchable
