screen too bright

hello my s5 mini, when exposed to sun for example, automatically increases the screen brightness...altought so much bright that even the colors became strange. anyway, since i am rooted, to change the maximum brightness allowed in auto mode?

I've just read an article pointing out this weird thing:

I've just tested this on my S5 mini, wow! I see what they mean by colours going psychedelic.
I don't think you have any control at all under Auto Brightness. You'd have to switch Auto Brightness off then slide the brightness to Max.

maybe some moding?

Maybe this is due to a feature named "Adjust Display". Go to Settings > Screen > Screen Mode. By default, it's set to Adjust Display, so the screen will automatically change its colors depending on ambient lightning.

[Q] Auto brightness doesn't work

Hi
The "Adapt to lighting conditions" is checked, but it doesn't really adapt. I have to manually change the slider to adjust brightness.
Looks like a bug. Not sure if there are any other settings to make.
Is this a known issue? Any workarounds?
Thanks.
Farhad.

The slider sets the maximum brightness of the screen, not the minimum. Hence, in order for the auto adjust to work, set it to the max and tick the check-box.

seems to work more like a brightness scale kind of thing. not only sets max, but minimum as well.
it'll always adjust when the box is ticked, but the slider determines how bright or dark biased it is.

It's a sliding window of brightness ranges, which should be good news to anyone who's felt that autobrightness on other phones swings too far in either direction. Now you can customize to your own taste.
Personally the sweet spot for me with good compromise between use in low light indoors, daylight and office lights is about 25% - the slider button just above the second "g" in "lighting conditions"
Remember though that changing White Balance settings will darken the display, and you'll need to boost brightness to get decent contrast again.

Use Lux Lite from the playstore. It lets you individually "link" a specific brightness level to a specific lighting condition, which the app then remembers and automates.

What do you mean "Source"?
That's how it work[s|ed] on my Xperia U, Xperia M, Xperia SP and now on Xperia Z3C.
Not proof enough?

It works, but doesn't work well. When I wake up at night the brightness level goes lower but not nearly low enough. I have to manually reduce the brightness to the lowest level. When the day starts, I have to manually increase the brightness. Not ideal, not a deal breaker either. Hopefully Sony addresses in the next update.

Totally agree, Im using lux to improve the brightess auto adjust....

[Q] screen backlight perameters.

I use my Z3C at night quite often and find that the backlighting is too bright even turned all the way down. The adaptive lighting option does not bring it bright enough durring daylight use if left un the low setting. Is there any way to adjust the backlight other than a 3rd party app?

Do you mean other than the brightness slider?

Install lux and set it to adjust brightness automatically depending on ambiant light.
Set it to -10 or 5% with 1 lux and 100% with 100. Etc. It take time to adjust it but will save your eyes and battery.
Donation isn't necessary but bring some good options.
Works like default adaptive brightness but with more steps (if you desire), darker or lighter...

After a few days with Lux, it is much better. It allows the screen to dim and brighten way past stock settings. I really like the night filter mode. When i am outside and check my phone i am no longer getting blasted by a spotlight bright screen!

Is auto brightness working good ?

I seach many threads but in my case it works but I have a probleme for having the REAL auto brightness with my Z3C.
I mean... If I disable the auto brightness in display settings an put the maximum brigtness it's very high, and when I check the auto brightness and put the brightness (notification bar) to maximum and switch between auto and not auto... YES there is a difference, the auto mode is less bright, so yes the auto brightness option works because i see a difference... I gess
BUT... at night when the room is COMPLETLY dark (yes because I sleep in the dark lol) the brightness is very bright for me, too bright. And I go to the notification bar and put it at less... but wait! This not my definition of "auto brightness" if I have to manage it. For me (maybe I'm weird, tell me) if auto brightness is enabled, when the light sensor see a COMPLETE DARK room the brightness should be at minimum, am I right???
And, with all my previous smartphones, the auto mode was with the brightness bar in notifications bar and if I check the auto mode, the brightness setting bar is desabled... and if I setup the brighness bar, the auto brightness check is disabled... etc
So why my Z3C haven't an real auto brightness? Why can I enable the option in settings but set the brightness bar too? Why in a complete dark the brightness is too high and not at minimum? Because in the morning in the dark if I set it at minimum, later I have to set it more bright because it's too low at the day ligh... BUT I'M IN AUTO MODE IN THE DISPLAY SETTINGS!!!
It's like I have the auto mode and the right to set the brightness too... not logic! If I check the auto mode it's because I don't want to setup brighness bet the device must do it for me like my others phones...
Is it normal?
Thank you for help...

Its normal, auto brightness on the Z3 has a very narrow range of auto adjustment. So exactly like you are saying its either too bright at night or too dark in bright light. Do yourself a favor and use the app LUX, I think there is a free version to try. My auto brightness now works as it should, bright enough to read in sunlight and dim at night so I'm not blinded. You can tweak the values for every type of.light you are in, works great.

Do you have Lollipop on your phone?
Do you know that in Lollipop there is no Auto-Brightness anymore, there's "Adaptive Brightness", and it scales less, which explains your experience (and you're not the only one)?

It's was called something with "adaptive" in Kitkat, too.
You can just set the slider to the minimum, then it won't be too bright in the dark and it'll get bright enough in sunlight...

Auto brightness with 5.1.1

When I got my TAB S2 it was with 5.0.2 and I was able to increase or decrease how auto brightness works with a slider in notification tray. After flashing T710XXU2BOJ1 (5.1.1) if I use the slider with auto brightness turned on it will turn off the auto brightness This is a bit annoying because I like to use auto brightness and now can correct it if it's not doing a good job :/ Is this a 5.1.1 feature or a bug and I should do a factory reset?
P.S. If I do a factory reset on rooted firmware will I loose root ?

Ok, to answer my question it's a bad feature off 5.1.1. Will have to do for now, maybe 6.0.1 some day will fix it

The whole point of auto brightness is just that "auto" the slider is disabled because the OS adjusts the brightness based on the light in the enviroinment.
If you are in a dark room it will dim, outside it will go bright. If you move the slider the device assumes you then want to use manual brightness and disables the auto brightness and then adjusts the brightness of the screen based on where the slider is positioned.
This is the way Samsung devices work. (I have had several over the years and currently have a Note 4, a Tab S 8.4, and this Tab S2)
How are you expecting the slider to function when auto brightness enabled?
The slider is suppose to be for manual brightness.

The auto brightness slider still allows for manual adjustment on 5.0.2.
-5 to +5 to set the level to your liking whilst still maintaining auto brightness mode.

Exactly, any way I could have this with 5.1.1? Maybe some xposed module?

I think I recall there being some form of auto brightness audjustment fix in the downloadable modules. I can't link you as I don't have it installed currently.

Couldn't find it ?
