Disable dynamic contrast? - One (M7) Q&A, Help & Troubleshooting

I hate the dynamic contrast on this phone. To the point im thinking of returning it to get another phone. I was reading this review
http://www.anandtech.com/show/6747/htc-one-review/10
and it leads me to believe that it is possible somehow. "The HTC One includes a dynamic contrast function which can’t easily be disabled, as there’s no option in the display settings for it."
Does anyone know if theres a mod to do this or how I could do it? Maybe theres a rom that allows this? Its driving me crazy the way the backlight adjusts constantly.

Errm do you mean auto brightness? As dynamic contrast really isn't going to be noticeable enough to annoy anybody, as proven with TV's.
Try just setting brightness to 1/3 of the slider.

No I don't mean auto brightness. I would never use dynamic contrast on a tv. It's terrible and I don't know how anyone can not notice it.

Dynamics contrast only affects pure black scenes and it is not really noticeable during a normal TV show. Apart from us lot most wouldn't notice it, but on this phone I can't notice It at all and it would be linked to auto brightness so that it tries to keep up a consistent experience. Try sticking a constant brightness and see if it's better

I am interested in the Dynamic contrast. I use 4 24in HP monitors at work and I actually am in the 5% of people who enjoy having it lol

[Q] Jeff Sharkey's AMOLED "night mode"

Has anyone attempted to/willing to try to implement this on the Captivate?
jsharkey.org/blog/2010/07/01/android-surfaceflinger-tricks-for-fun-and-profit/
This is really interesting. I'm into astronomy and it would be awesome to not have the phone blind me everytime I turn it on during an observing session to use it for google sky and the atomic clock.
Apparently no dev types are interested enough to tell us that they are not interested.

No doubt.
This thing is blinding even on the lowest brightness setting.
Yes, the brightness is pretty ridiculous. Is this because of the AMOLED screen? Can't set brightness below "blinding" due to no backlight?
I have heard that the leaked I897UCJH2 rom has a lower mininal brightness; which might help with the blinding brightness at night, and also helps bettery a bit.
Not sure if you guys are interested in leaked ROMs but I'm sure if Samsung does not release it that a cook will make a custom rom from it.
looks awesome
Bump.
I think this would be extremely useful.

on Google sky map theres a night mode option when you press the menu key.
I seem to recal hearing that at a certain point when the voltage is too low the screen will still work, but you see glitches/artifacts.
So im assuming this is why the min brightness is set where it is.

There is that very low brightness that occurs when you have less than 10% battery life. I wish they would make that brightness user selectable.
Even if the screen cannot be physically set below a certain level of brightness, it would be trivial to have the OS do the equivalent of putting a partially-transparent black rectangle over the screen. Sure, color fidelity would suffer, but it would be a welcome option anyway--I have seriously considered wearing sunglasses in bed.

wow, i think your right.
instead of trying to set the brighness lower just put a transparent gray object that sites on top of all the windows.
It would have the same effect and save tons of battery.

Search for a widget called Curvefish Brightness Level in the market. Set it to 0% brightness, which appears to be the same as the low battery life brightness.

Hello,
are there any solution on lower brightness in jp6 like voodoo 4 on 2.1?

Just slide your finger along the notification bar.
app called "brightness level"
set to 0%
Interested in this as well.
I think we are actually looking for something lower than 0%
It is probably the amoled screen vs backlit one, the way they operate. 20% on lcd is much lower than 0% on amoled.
Maybe there is some kind of overlay that can act as Rayban? Like ie when you do Titanium backup, you can see the rest of the application being much darker than the notification that pops up. Probably some overlay being used.
Maybe some of you asking yourself why, but try using it in complete darkness for awhile and you'll see what I mean.

Thanks for help.
Mybe a dev or supercurio can help to explain
Yes, the lowest stock level is already quite bright, too bright of course for night use in bed.
You'll also notice that the colors & contrast looks quite dull on the lowest stock brightness settings, with a color deviation in the red shadow colors.
With the revamped Voodoo color which will be released step by step during the next weeks, you'll be able to go so "dark" (if chosen) that you'll be almost not able to see it in the dark even when on
All that, preserving color accuracy and color temperature (which goes more red when you lower the brightness on stock)

[SOLVED] Xperia T - screen dimming

Hi, I love my Xperia T but there is one thing that bothers me. I noticed that every xperia T has that automatic screen dimming when viewing darker media on your screen. For example, when i turn on facebook app, before the actual app opens there is dark grey screen. During that sequence screen gets darker, and when white facebook page pops up you can actually see screen adjusting its brightness to higher "normal" level. That really bothers me especially when gaming. On dark sequences screen gets really dark, and than it takes second or two to adjust normal brightness when brighter sequences appear. You can actually see brightness going down when darker images are displayed, and then back up again when brighter images appear.
So I'm not talking about dimming when overheating or flickering (that second is fixed by jellybean update as I noticed), or etc. And before you ask me I if turned on autobrightness in display settings, it has nothing to do with that.
My question is, is there a way to turn this off because it is really annoying?

All i thought it differs to auto brightness thats why i ask it sir. Sorry for the question then
You dont have to apologise. So, the problem is that when you watch darker images, or videos, or just any darker screen on your display, contrast and brightness goes down. And when you switch to brighter screen you can actually see, with your naked eye, brightnes going up. I see that Sony intentionally put that feature, but it is very, very stupid one. There is no point in making dark images even darker with even less contrast. I assume they wanted to achieve better black levels that way, or I don't know, but it is very stupid way of doing black levels more black. And, of course, there is no setting in settings menu tu turn this nonsense off, nice one Sony!

This similar annoying ass feature is there in my Spectre laptop. This was supposed to be a battery saving feature and I haven't yet found a way to turn it off. Maybe it's also a way to get higher black levels.
This is the Bravia Engine. Just unselect Settings -> Display -> Mobile Bravia Engine

Dude, this is definitely not a battery saving mode. There is no need for batery saving mode when displaying dark screen, and the problem occurs when displaying dark images or any other dark media, app or non-app. every single time.

OMG... Mobile bravia engine has apsolutely nothing to do with with that, because bravia engine works only in phones stock apps for viewing videos and pictures, and the effect is not even similiar to screen dimming. It brings more saturated colors and that is all.
Same problem is posted here: http://communities.sonyericsson.com/thread/61560?start=0&tstart=0 and Sony replied "I'm sorry that it has taken so long but I have done some testing now using a later software and I'm not able to replicate the issue that you guys report so I assume it's fixed." It is more than obvious that they like to close their eyes on every single problem that occurs. Thank you Sony for your gorgeous support to your beloved customers. I cant be more sarcastic, of course.

I'm terribly sorry if I ofended you, and I apologize for my attitude. I'm not mad at you, or anybody else here, I just don't see why would one write something just to be written. I know my T-Rex wery well, and I know there is no "normal" way to turn this dimming crap off, so I posted my question here, and expected that someone of the experts would offer some kind of solution to that. And I got things like "turn automatic brightness off", or "turn mobile bravia engine off" even though I previously mentioned that i tried all that stuff. People are "trying" to "help" me here, and they didn't even read what I've written. I'm really not one of guys that would post a question here just to be posted, I searched the crap out of the internet, and I found apsolutely nothing helpfull.

Thank you guys very much! Changed values, and rebooting my phone...everything is fine now, no more stupid dimming. However...I noticed that color adjusment is still visible when changing from dark screen to colorfull bright one. So the dimming is now definitely gone, but that color adjusment is still visible, like it changes contrast a bit, from worse to better, it is clearly visible. Any ideas about that?
I'm uploading a video I recorded with my webcam to get you a closer look. I'll post a link once it's uploaded.
Video will be live here in a couple of minutes: http://youtu.be/fHozO8zGZ1Y
After I managed to turn off DLS, that auto-contrast thing still remains. If you look closely, you'll se that the blue facebook stripe (and everything else) slightly changes its color/contrast when returning from the gray screen. But DLS was much bigger pain in the ass and I'm very pleased with the result od turning it off.

[APP]OLED Saver (flicker free backlight dimming, no PWM)

This app is a life saver for anyone who suffers from "invisible" screen flickering caused by PWM backlight control. Most AMOLED displays control lower than 100% display brightness by PWM. This method is extremely easy to implement, but can cause eye strain and headaches for sensitive people. DC dimming is rare as it is hard to implement without sacrificing color accuracy. This is where OLED Saver comes in handy.
How to use:
- turn off system adaptive brightness
- install the app, allow permissions it requests and enable the service
- set minimum screen brightness to 255 if you want to have the safest value (guaranteed to have zero flickering). After further testing, values as low as 96 seems to be still safe - but test it with your phone to be sure.
- minimise the ongoing notification to hide it from lockscreen
- turn on automatic brightness change from the notification ("A")
- remove OLED Saver from battery optimizations
In some rare cases you will need to suspend the service from notification (while taking screenshots for example, app installer might need it disabled too).
If you have Tasker and root access, you can toggle the service to force 100% brightness automatically. I'm using 100% while viewing videos/pictures and taking photos.
Start service
Code:
am startservice org.js.oledsaver/.MainService
Stop service (this will remove also notification)
Code:
am stopservice org.js.oledsaver/.MainService
So far I haven't found any negative point while using this app, just wish it was included in the AOSP code so we could still use adaptive brightness. Anyway, give it a try and share your experience.
I used to have some trouble watching text on this display under certain light conditions.
I don't know if it is just a placebo effect, but since I've installed this app, I don't feel any discomfort anymore.
I also can't see any difference in picture quality.

You can easily check if it's working with another phone's camera. People have different sensitivity to PWM flickering, from none to watering eyes. You are probably somewhere in between. Without the app, I had a slight feeling like something was pulling my eyes. As soon as I enabled the app, this sensation has been gone. My wife doesn't see/feel any difference, but I left it enabled for her anyway, just to be on the safe side.
Thanks a lot for introducing this app. It works.
However I encountered a problem. With this OLED Saver activated and using GCAM to take photos, it boosts the brightness to maximum. Then I went elsewhere like home screen or other app, the auto brightness seemed not working and kept the max. brightness.
Then I tried locking the screen and unlocking, the brightness went up or down randomly, or it worked in some particular patterns I don't know. Anyway, it can't keep the brightness I set previously.
Does anyone has any idea to remedy this? Thanks a lot.

Which GCAM app do you use? I'll try it. In stock camera it doesn't behave this way.
Btw. I tried to contact the developer if he could add global intents so we could control OLED Saver with Tasker and without root, this should help in preventing this kind of behavior. No response so far though. If you are rooted you could use method mentioned in the first post.
Also I'm in touch with Velis Auto Brightness developer - this app offers much more features (customizable automatic brightness levels, apps exclusion and more) and has similar feature for OLED displays, but sadly it doesn't work on status/nav bar as of now. If he manages to use the same method as OLED Saver, we could switch to VAB app.
The GCAM version is 7.0.009.259843690.
Phone model is M1906F9SH (64G global version) with OE ROM.
Thank you.

Hm, I can't replicate this. I've installed GCAM, enabled max brightness for pictures (but it does nothing, as system brightness is at max already and real dimming is done with OLED Saver, which is not being controlled by GCAM). Moving to/from GCAM doesn't change anything. If I manually suspend OLED Saver from notification, GCAM shows max brightness correctly. On resume it returns to the expected behavior and dimmer display.
Yeah, sometimes I got what you described. Sometimes it rushes to very very bright, but sometimes it can be very dim...
I'll try reset it again and see how it goes. Thanks for your time.

I think that I saw OLED Saver "crash" once while using the phone - brightness suddenly went to max and was controlled by system. Since I removed this app from battery optimizations, it seems to be stable. Though this does not explain rapid bright/dim changes.
This looks very useful but what is it doing exactly? Is it running the screen at max brightness at all time and using some kind of overlay to dim the screen? Isn't that bad for battery life?

Yes, as you said, running HW brightness at max and putting a translucent overlay over the screen. It's basically SW implementation of DC dimming. It has a small artifacts with very low brightness, especially on grey colors, but otherwise no issues. Impact on battery should be negligible (OLED displays work different than LCD).

Hi _mysiak_,
I changed to some other version of GCAM (without the max brightness view finder) and then this OLED Saver App is working fine afterwards. Thank you.
Then I found, when in very dim setting, occasionally, the white color (now it's actually gray) seems not stable. It could be fluctuating from neutral gray to warmer. Not intrusive, though. Do you see that?

Yes, I noticed that "slow flickering/artifacts" as well. I believe it's the side effect of DC dimming method and probably one of the reasons why it's not so widely used. From what I read, Samsung AMOLED panels are designed to be used with PWM dimming, so we probably can't avoid it with very low brightness. If it's too disturbing, I just move the OLED Saver brightness slider a bit higher (it stops completely at roughly 40% brightness). Using pitch black themes in apps helps too. Not a perfect solution but definitely better than PWM
Btw. it's the same for any app using translucent overlays, I tried a couple of them and at similar brightness, all behave the same.

Has anyone used a high speed cam to determine at which brightness level the a3 flickers, or is it all level below 100%

It seems to be at 80% and below. 81-82% and above should be safe.

Try to change the "basic physical brightness" to value 96, artifacts don't disappear completely, but I don't notice them so often.
Level 96 in OLED Saver corresponds to HW brightness level 82%, which seems to be still free of PWM.
Thanks for the tip.
It's really works. Thanks for the tip ???

Request: Module to lower screen brightness below minimum slider value

When using dc dimming on my amoled phone the brightness is way to high at night at lowest slider value.
While with pwm its a lot better i still would prefer it less bright (anyway no solution because flicker is annoying at lowest brightness).
Im pretty sure i am not at the lowest possible brightness level.
Unluckily beside some third party apps which running in the background and overlay a black layer i couldnt find anything useful even tough tons of people looking for a solution.
Your battery would thank you aswell .
Please can anyone make a module which sets the lowest brigthness to 1 on boot up ?
Thanks.

Don't think there is currently a module available. Having the same problem with my second mobile. The only App that I found and which is working as expected is for me:
Darker (Screen Filter) - Apps on Google Play
Darker can lower your screen brightness to extremely low levels.
play.google.com
Maybe anyone other knows a better solution.

Yeah this one uses a overlay, no good solution unluckily.
Hopefully some dev pick up my request.
