The light sensor is really annoying! Actually, it turned off in display settings, but i see the brightness jumping all the time, it is really, really really annoying! I want to turn it off, or switch it totally, is it possible ? This brightness jumping is torture for me ((((, sometimes i have a strong wish to disassemble the phone and cut this sensor off. Could someone give an advice how to turn it off totally?
But it's no more the light sensor.
It's caused by thermal throttling. You can edit those values in /system/etc/sysmon.cfg to your likings, like I did. I found, that brightness values are not needed to be so low.
If it will really work, i will pray for you, man
Thank you!
I see there`s a lot of values of brightness in this file, what is the maximum value of brightness ?
And what values do i have to change ? All brightness values in the long list ? Or somewhere else ?
For now, you can just change the brightness values, maximum is 255, but still, for the highest temperatures, do not set more than 190.
Ok, thank you.

I noticed the phone also dimming/brightening the screen respectively colour temperature or sharpness ratio (or whatever it is changing to influence image reproduction) in recovery. Does the recovery pull in the same configs the full OS does? If it doesn't it must be the hardware doing some trickery to the image.
I don`t understand, why Sony done it ? I had Xperia Ion before T, there was no brightness jumpings. Maybe the screen of T is more sensitive, or something, so it needs lower brightness when the phone is too much hot? I can`t understand...
I found that Xperia Ion does not even have this file, sysmon.cfg. What for this file in T - this is the question.
Because ION does not have Qualcomm S4 processor.

Hi all, I was wondering if anyone new how to lower the brightness level to below that of stock, up to the level of night mode if I needed.
I like to do a bit of browsing before I sleep, and the brightness levels even on the lowest hurt my eyes! If anyone knows how to do this I would very much appreciate it. Thanks!
UPDATE: Issue helped, and possibly resolved with the help of my mate Rich @ Geek you Up. Check out his app in my thread:

Ive been looking at the Auto-Brightness thread and it seems Cyan already knows how to tweek the brightness values, but I dont even know what a github is let alone the deving needed to acheive this.
cyanogen said:
Anyway, the Desire has 10 auto-brightness levels, and the N1 has only 5. These are just an array of lux/brightness values. I put them into my vendor overlay and rebuilt, and I have to say it's much nicer. I'm going to include it in the next CM.

Cyan if you can help, I would appreciate it!! But understand if the modding is far more important
Like how the brightness dims before the screen auto turns off, or how it is dim when you tap the sleep button in the clock application - these would be good. As for that stock widget that controls the wifi,blutooth,gps,sync and brightness, i never touch it because it messes with autobrightness, but if it could be changed to temporarily go really dim thatd be perfect

Either my friend! The clock application goes even dimmer than I want, so somewhere in between would be great. But I'm sure that could be customized, I just dont know where to start looking..
I'd be really interested in this too - I like reading in bed before going to sleep, but the wife doesn't like the light being on. I have to angle my nexus slightly away as it is too bright, even at the lowest setting, to have it directly facing me while in a dark room.
Hi,
When surfing at night the minimum brightness is still to high. Any apps or hacks that allow to dimm the screen more?

Same here, seems like it could go down lower but it doesn't. I think it'd also be overall nice to be able to adjust the behavior of the automatic sensor, but in this case, the automatic sensor in darkness is at least the same as manual turned all the way down.. My old phone it wasn't.
Hi!
The automatic brightness on my Xperia Z behaves weird (altough I think it is a bug)
This is what happens:
I have the phone set to "adapt to light conditions" (automatic brightness)
Now when I slide the brightness slider, the brightness changes. But, depending on the setting of the slider, it will not go to full brightness or darkest on its own. When I turn off "adapt to light conditions", it becomes brighter or darker, depending on slider position. But it will never go to 100% on it's own, not even directly under a lamp. It also becomes a little brighter when I turn off automatic brightness and have the slider set to 100%.
Expected behaviour:
I turn on automatic brightness, and put the slider in a, let's say, 60% position. The phone goes to 2% brightness in a pitch dark room (when I read in bed) and switches to 100% when I'm outside in the bright sun. When it does not sense extreme conditions (e.g. sensor reading <20% ambient brightness or >80% respectively; then gradiently going to darkest or brightest gradiently, of course), it aims for the +-60% brightness I specified with the slider.
Conclusion: The slider is an overall threshold for screen brightness and it does not adjust in a 2-100% brightness range, but around maybe +-30% or so around the position the slider is set at. This sucks!
This seems to clearly be a bug, and imho this contributed to the somewhat "not so impressed with the screen" reviews I read before I bought it. Because the screen is really very good if it is set to the correct brightness.
Thanks for the answers!
PS: When I enter the service menu with *#*#7378423#*#* and check the ambient light sensor, it gives me values between 0 and 1000 - so it does definitely work correctly. Build number is 10.1.A.1.350 - I know there is a newer one, but my phone is carrier branded (3 Austria, for that matter) and hasn't been updated yet, unfortunately. Can someone confirm that is is fixed in .434?

I dont think this is a bug. It's been like that on the t, tx, v since they were launched.

Really? This is almost a deal breaker for me :/ that is a really stupid behaviour, what do I need automatic brightness for if I have to change it myself anyway? I really don't want to care about this miniscule thing on a 600€ device - I expect it to adapt to all conditions.
I didn't want to root it or put a custom rom on it - Sony did a good job with the software as it is, except the automatic brightness.
Sony phone has the best auto brightness
You can find on any phone.
You can say Samsung's auto brightness sucks but not Sony
In auto mode you have the choice to set the minimum brightness level you want and the level will go up depends on the lighting situation and sensor reading.
Yes it has some threshold limitations but it's very sufficient.

Sorry, but "best auto brightness" is not what would've come to my mind thinking about the xz and I would never buy a Samsung plastic brick
I had a Nokia N9 previously (that I miss dearly, but the internal 3G antenna was broken so I had to replace it... still by far the best phone I ever owned) and it had exactly the auto brightness behaviour I expected - when I read in the dark, it when down to the lowest possible setting. And when I was in bright sunlight, it went to full brightness wihtout a delay or hassle. I could read it perfectly under any condition and never thought about the settings. The slider only indicated a preferred standard brightness - always had it at 60% and it was perfect.
I really don't understand why other manufacturers wouldn't do it exactly the same way? As I said before, why even have an auto brightness setting if I have to go to settings to adjust it anyway?!?! If I put the slider on 60% and auto brightness on, it burns my eyes in the dark and I can't read it in bright sunlight - I even have to adjust it when the sun shines through my windows at work?!?! WTF Sony?
We are talking android here
I don't know if you had the chance to use gingerbread,froyo....
Maybe android has some limitations.

iirc it didn't annoy me (and boy am I picky about details like that! ) on the HTC Magic (up to the last CM that supported it) and the Nexus S I had before the N9... anyway, seems I have to get a decent brightness toggle widget :/ (maybe you can point one out?)
but thanks for your replies!
just for the record and anyone who may find this thread in the future:
I just installed "Auto Brightness" and it seems to work well and has tons of settings. Would have preferred a more native solution... I hope this doesn't drain the battery.

Recently I've had my phone display repaired and the very first thing I noticed was that the brightness on the replacement display was not working. I tried wiping data/changing ROMs and confirmed that it really is hardware related.
My solution is to use LiveDisplay Color Calibration from LOS. What is does is basically reduce the screen "brightness" by reducing the RGB values. It does a relatively good job at preventing my eyes from drying out at night.
Now, the problem is that everytime I need to increase/decrease the brightness, I need to manually go deep into Settings to adjust it. Is there any Tasker profile to let me adjust those values on the fly? Or at least to profile a low-brightness value on one tap?
I found a thread on r/tasker that is close to my problem, but isn't really doing anything. Any help would be greatly appreciated.

Test the sensor light under the screen

I'm not sure what you meant by that but my phone doesn't have a light sensor.
I am experiencing automatic dimming of my screen when set to maximum. The big thing is Adaptative Brightness is Off. I also set Power Mode to High Performance to make sure power management would not dim. I even bought an app that supposedly cranck up brightness beyond system limits (did not work)
I first noticed this when taking pictures of my garden in bright daylight, the screen was dim and even going over the orange marker on the dial I still struggled to view the screen (sun was almost 90 degree angle).
However when I placed my hand over the screen I could see well but then I noticed a sensible dim. At first I thought it was some king of optical trick, so I tried to repeat the experiment in different conditions to the point that I would simply crank up brightness and have a strong light over my phone then I used a black sheet of paper just above sensors. If I take the sheet off the brightness ramp up a bit, if I put the sheet over the screen dims. And again no auto Adaptative Brightness is turned on neither Power Mode in save.
I guess this wasn't supposed to happen, if I want to ramp up brightness as much as I want I should be allowed and the system should not interfere with my preference? I don't need to justify my use to anyone but as a courtesy to those that are inclined to help me, here it is: I work a lot with gardening and construction all day, including strong daylight, and I need to take a lot of pictures for my work.
What can I do to squeeze this bit more brightness from my Note 9?
Thanks a lot.

Try the the twilight blue app filter. It works wonders with the bulb features on your phone
