Hello all,
I'm just curious as to how this feature is supposed to work. I have my device set to automatically adjust while it's on medium brightness and I've noticed that the brightness jumps from low to medium frequently, especially when I'm on just one page.

I believe it just counts the number of white pixels on the screen on the omnia. this is why it jumps so much. The only way to prevent the jumping is to set the birghtness on low, with the auto setting off. Even on medium or high it jumps when the page has a certain % of white pixels. Like for opening the browser its really annoying however on low brightness the colours are really nice and its just perfect for me. Its just too bright on med or high brightness for my preferences.
But the way how the "feature" itself work I have no clue. Maybe a light sensor. But the jumpiness is caused by the number of white pixels on the amoled screens, and occurs only on samsung devices I believe.

Thanks for that explanation, Marvin
I couldn't find the original thread about this, so I'm making a new one

Theres a video where i film after the 1.28 patch, and as you can see the top isnt making that weird thing anymore, Its just the screen flickering or how i should call it.
You barely see it, but you can see in the video that theres something happening when im moving up and down.
i think the problem is by the ambient light sensor beside the hTC logo
so when your fingertip pass thru the sensor, the light enter reduce so it become brighter...

What is an ambient light sensor on a monitor?
It Is A Sensor That Detect Light So If Its Dark Your Screen Monitor Brightness Will dim down so you're not looking at one source of extreme bright light, When Its Bright The Screen Monitor Will go up to compensate for the extra light around you so you can still see the monitor comfortably

No, that's not it. It's a software bug, the fixed it just a little. It's probably driver problems still. If it was the light sensor it would just dim, not blink.
still the bug is there.. but less than before.. mine screen flickers (not the screen flicking bug) when the bug hits.. just in an instance.. and distorted the date a little than before.. updated to 1.28.415.9 Arabic version
Well mine still makes the thing where everything in the bar gets all blurry.
Just not as often.
So the bug is still there but they sure did something to improve it
Edit: yeah ayan15 did a good description of my bug
Sent from my HTC One X using XDA
This is my first AMOLED screen phone and something I think I may be noticing that maybe you guys can help confirm or deny about AMOLEDs vs LCDs, is that at night when turning the brightness down (way down, like -50 in the Lux Dash app as an example) results in getting the screen to a point where not bright enough to hurt your eyes at all but the blacks are too dark. So there's no real ideal brightness setting in a dark room that equals no eye pain but still allows you to able to see everything on the screen. Or are my eyes just too sensitive and most other people don't need to turn it down as much as I do and therefore don't have this problem?
You tried night mode
Lux is garbage. Factory adaptive brightness and still being able to use the brightness slider to allow on-the-fly adjustments is far superior - it works perfectly on this phone. And in a pitch black room, with adaptive brightness, setting the slider from 0-25% results in an extremely dim screen (1-2 nits) will information still perfectly viewable. Blacks may have uniformity issues, but that is the nature of OLED panels since it is extremely hard to control voltage at near-black levels when the brightness is extremely low.

Amoled displays, when used with automatic brightness adjustment, have a small problem - when you are viewing them in the dark, they appear too dark. Their contrast ratio is infinity, which means that dark colors are basically zero luminosity or close to zero. A lot of internet imagery is calibrated for lcd displays, so when you lower your phone brightness to make the brightest parts viewable on an amoled display, the dark colors become too dark and blend together. This is especially true when you are viewing a screen in a dark environment. There's nothing you can do but increase device brightness by hand when you are using automatic brightness adjustment and viewing in the dark,

You do realize that Adaptive Brightness simply changes the brightness of the screen in response to the light sensor reading?
In other words, the phone doesn't care about your preference - it will change the brightness to preset levels.
On Samsung phones, this situation is far more intelligent. The phone still uses the light sensor to adjust the brightness, but the phone also applies a user preset to augment the brightness - when you slide the brightness slider up, the phone will make auto brightness adjustment higher, and vise versa.

WHAT? You have it totally backwards. Stock Android, including the Pixel, uses user input to augment the auto light sensor brightness when adaptive brightness is enabled. If my phone thinks 50% brightness is appropriate, but my slider is set to 100, it will choose something like 75% brightness instead. If I drop the slider to 0% in the same instance, it might choose 25% instead. The user preference will ALWAYS be impacting auto brightness.
Samsung phones, unless it changed with Nougat, rely strictly on what the phone thinks is best for auto brightness. The user can adjust the slider with auto brightness on, but the slider is a direct adjustment 0-100% of the true brightness level, and the slider will change automatically when there is a large shift in ambient light after the display has been turned off at least once. User preference does NOT impact auto brightness unless you set it at that specific moment.

Girl, are you kidding me? I just returned a Note 7 for Pixel XL. What were your phones?

I have a Note7, Pixel XL, and LG V20. Google how adaptive brightness works. There won't be a single article that matches how you say it works.

Give me evidence. I don't care what your hypothetical "articles" say, I had the actual phones and played with their brightness settings.

If you seriously can't tell how adaptive brightness works just by using it as compared to Samsung and LG, I don't know what to tell you. It's pretty damn obvious. If I'm the kind of person who prefers a bright screen, I can set adaptive brightness to 100% and it will always be bright, but stay relative to the ambient lighting. If it's a dim room, the screen will be bright, but nowhere near 100% manual brightness. It only hits 100% manual brightness when under bright light like the sun.
Samsung's auto brightness is still very cookie cutter. If you put 2 Samsung phones side by side with auto brightness on, they will always be the same no matter the ambient light. If I take 2 Pixels, both set to adaptive, and put one on 25% and one in 75%, they will always maintain a brightness difference even when ambient light changes. Samsung phones do not maintain user preferences once the ambient light level changes. I almost never have to adjust my Pixel. I always have to adjust my Note7 because I prefer a slightly brighter screen.

What you are saying is EXACTLY THE OPPOSITE of my experience with Note 7 and Pixel XL. I NEVER had to adjust my Note 7 brightness once I set it.
I find myself constantly adjusting Pixel XL brightness setting.
Maybe they both have "adaptive brightness", but the Note 7 version was perfect, and the Pixel XL is just sh`1rt.

Or maybe you two just have differing opinions on what a "perfect" brightness setting is...
Doesn't matter how you adjust your brightness. I'm just saying that when brightness is low, blacks are darker and disproportionate to other colors.
I love Lux especially with it's profiles. Much better control and accuracy than adaptive brightness. I just wish Lux had an auto-profile switcher based on time of day. I have a day profile, night profile, and car profile.
One thing to note is that Lux allows me to bring the darkness down below 0% to negative values, which is where I usually notice my concerns. But that's what I need to not hurt my eyes at night. So I don't blame the phone or anything - just posted this article out of curiosity. The blacks are probably just turning off completely at some point when I bring the value to below 0% which I think makes sense based on the nature of OLED.
You should just turn on night mode to help with eye strain. If 0% brightness is too bright I don't think you will ever get lux to work the way you want, but night mode helps my eyes a lot.
Pixel XL adaptive brightness adapts to what you set the brightness to. If you go from 0 to 100 in a totally dark room, you notice how the screen stays really bright and doesn't go back to 0 on Pix
Many phones use auto brightness to fullly determine brightness based on sensor and ignores user brightness. If you go from 0 to 100 with an auto brightness phone, the phone will go back to 0.
Some prefer one over the other.
Dose any one notice in mi A2 lite saturation increases if high beam of light hit light sensor. Even sunlight is enough to increase saturation of display. I have tried disabling adaptive brightness but no change it increases saturation. I dont know this is a defect to my device or an 9 pie update bug.
I have this also
You can find this setting under developer options as "increase readability under sunlight". Disable it and you'll be fine.
I'm still not sure in which condition it occurs if it is due to sudden light sudden intense light.
Basically it will start to glow (it increase the saturation I guess) depending on the colors of the current screen ( on screen with dark colors the saturation increases and vice versa)
I have then to reboot to fix it.
I'm still using 10.0.3
Hi,
is there a way to change the brightness on the fingerprint sensor. I believe even if you put your brightness to lowest the fingerprint's brightness remains the same when idling.
I'm scared because it might cause uneven display or burn-in issue/s.
Thanks
Are you using Always On Display? If not, then there's nothing to worry.
