Dynamic Brightness?

Apologies if this has already been raised in another thread, however, I've just got my HTC One X and I've turned off the auto brightness.
However, even with auto brightness turned off, if I pull down the white status bar (or even view anything with a white/light background), the display appears to get brighter. Then when I return back to the launcher, it "fades" back to the original brightness over approx 1 sec.
Is this the "flicker" that people are reporting, or is this simply the Tegra PRISM function? Either way, can it be disabled? If I've set the brightness, I want it to stay that brightness, regardless of what I'm viewing.
Si

exactly the same happens here with my HOX. i dont know if this is the "flicker" everybody is reporting, but a way to turn it off would be nice.

i think thats the wrong section..
however, i got the same issue, but its gone after 3-4 weeks, OR it was fixed by a custom rom.

This is "dynamic brightness" implementation is called "tegra prism". Search for it.

New SIII (former HOX) - Screen questions, etc.

So, I'm coming from an AT&T HTC One XL and I have a handful of questions. The screen and the camera on the HOXL were borderline perfection in my opinion, but the phone had a few flaws led me to an SIII.
1) The auto brightness on the SIII is laughable. The HTC One X was seamless and smooth with its auto brightness adjustment, and I never once turned auto brightness off. I have had the SIII for a day and I cannot stand it. Are there any solutions out there for the jerkiness and delay of the SIII's auto brightness function? If not, what do most of you keep your brightness at? Right now, I'm finding ~70% to be fair. Anything below that is a sacrifice and I don't do sacrifices for battery life.
2) Pentile.... I cannot stop noticing the pentile. Granted, I am coming from perfection in terms of screen quality I was hoping it wouldn't be this noticeable. To exacerbate the issue, I use my phone an awful lot as an e-reader. My eyes were playing games with me while using the Kindle App last night (same settings as One X). I kept blinking as I thought it was a result of my eyes, but it was the screen. The font simply does not have smooth, sharp edges. Will my eyes get used to this or is this going to be a constant battle?
3) I recall a setting on my GS2 where I could sync up phone call ringtone volume and notification volume when I adjusted the volume on the side of the phone. I did not find this setting on the SIII. Does one exist? I
4) One the One X, when I had headphones in, notifications and phone calls would be pumped through the headphones instead of the loudspeaker. Is there a setting I can enable where ringtone and notification tone flow through headphones when attached?
Thanks!

1- I personally use a modded auto brightness but you can probably find a app that will do a better job at it than stock firmware. I believe there are some in here as well (in the app section of XDA).
2- Never had a android that didn't have a SAMOLED screen so I don't know what difference you're talking about. Although, I use my phone quite a lot as well and my eyes don't get tired. Keep in mind that screen brightness too high = damages your eyes, too low = hard on your eyes.
3- Settings -> Sound -> Volumes -> check link volume.
4- That should be on by default. If it's not, there's either a app that changed it or you did yourself.
Btw, what firmware are you running?

Thanks for the reply!
3 - Don't see this setting...
4 - Ya know what, maybe I did. The only setting I changed was unchecking "connecting earphones will enable audio applications in quick panel" in the Accessory menu as I didn't like all the apps being displayed in the notification area. I wouldn't think those are related though...
EDIT: I'm on stock ATT 4.1.1
EDIT 2: Just tried checking the box I unchecked for the audio applications and notifications still play through loudspeaker..

Brightness reduced when some apps launched

With auto-brightness turned off and brightness turned up all the way, I am seeing the brightness go down when some apps are launched and turn back up when the app is closed. I noticed this today when launching GoChat and then also saw it when launching the stock jellybean web browser. I am not sure but I think this has only been happening since the last software update (T-Mobile USA).
I wonder if others are noticing this.

Saw the same thing when I launched camera app, I am on the latest update.
One difference is that I'm on auto bright and the brightness never came back

From DisplayMate:
Since the display often uses 50 percent or more of the total Smartphone power, various display power management schemes are frequently used. The Galaxy S4 uses one innovative approach to overcome this – when Automatic Brightness is turned on, the Peak Brightness becomes significantly brighter in high ambient lighting than is possible with Manual Brightness, up to as high as 475 cd/m2, which is 34 percent higher than is possible with Manual Brightness. This is done so that users can’t permanently set the brightness to very high values, which would run down the battery quickly.​From Samsung:
Samsung Adapt Display: The Galaxy S4 "learns" what you are viewing and adjusts the display's brightness accordingly. If the phone senses you are reading an article, for example, it will illuminate from a more muted brightness.​

Well, I have auto-brightness, auto adjust screen tone and power saver ALL TURNED OFF, but this 'feature' persists... and as I said, this is not just during web browsing, this is also during messaging with a 3rd party app, namely GoChat, with black background theme.... this is just not a smart feature.

maybe this is taken care of in the new update. i haven't unpacked it just yet. hoping to do that over the weekend or maybe even tonight.

What you're describing sounds like how Adapt Display is supposed to work. Does the display act any differently when you enable Adapt Display?

I have the same issue. Turned everything off completely and it still happens. I posted about a week ago and some people were having the same issue.
Some people said it was adapt display on, but I have it off. Once I switched to.the CM10.1 the issue went away. I switched back to wicked Rom and I'm still getting the same problem.
Maybe a dev will eventually figure it out while building a Rom

It seems like this is a feature that cannot be disabled by the end user. This is from Anandtech's review
"On the brightness front, the SGS4 includes dynamic contrast functions that cannot be disabled and change as a function of what is being displayed. There's an "auto adjust screen tone" checkbox under display but don't let that fool you, that doesn't disable dynamic contrast, just white point."

If it really annoys you, you can always try rooting it and install CM10. I'll be a drastic change but at least you wont have to deal with Samsung's bloat

Missing Light/LED notification on Galaxy A50

Thread closed, previous thread on same topic exists
I bought the Galaxy A50 a few days ago and I'm terribly missing the LED notification option.
It does have the 'Flash notification' options, using the camera and flash sensors in the back or screen flashing, but they are worthless.
Tried various apps but nothing works as it should: you have to live AOD always on, it does not always work and it consumes a lot off battery.
Is Samsung working on adding this option (using front camera light notification) or is there any other way to work around this?
Thank you.

I'm surprised no one made an app for phones with OLED displays to use few pixels of the display to act as a notification light...
Or is there something like that?

Question Screen Brightness

I've had my Z Fold now for about a month and I've been noticing an odd fluctuation in brightness. I've made sure that the auto brightness option as well as eye vision comfort are disabled. I still seem to get random drops in brightness even with those turned off. Is that something that just happens with this being a AMOLED display? For instance today I was on my messaging app. I was watching the brightness in real time drop and then go back up. Drop and then go back up. I've never noticed that with other phones. Any help or explanation would be appreciated.

I have noticed this too and thought it was me. It is not due to overheating because it happends in browsing, mails and just viewing the gallery. I have all screen related adjustment set to manual or locked.
