Sorry for my english..
when I switch from an app with black screen (notification bar xda app etc etc) to a bright one.. Like whatsapp I see a strange thing... There is less contrast for 0.5sec then contrast is perfect and all is normal...
I don't know if you understand what I mean...
Is this normal? Or is a fault display?
Happens with stock and cyano... Full brightness and at lowest brightness...
thx for the replay

Thermal throttling is normally given as the answer to this.
Thanks for the fast replay... Then I must change my device? Or it'snormal

Its normal, but there are ways to change the way it does it, I am not an expert but if you root you can start to cange values. Search for thermal throttling values and you will hit a good thread about.
Yes I have root.. But I didn't understand.. For thermal throttle you mean cpu? Or even the display?
cause I don't have problem with multitask or other.. Only this strange problem that image quality is not perfect when switching to dark image to bright one.. But for less then a second.. But is frustrating and strange

as i said i am not an expert, but if you search in this forum you will find other threads that will give you information on which files to modify and how to do it...

ok i found some 3d about termal throttle and is not my problem.. i tried different mod but nothig...
i uploaded a video to show my problem ...
see the contrast change?
is not brightness...it's contrast that changes...
Yes, a have this effect too. I`ve changed brightness values at system/etc/sysmon.cfg, to a maximum values, after that screen doesn`t changing brightness when device is more hot, but this effect like in this video, is still exists! This contrast shading are not a termal throttling, this is something else, i don`t know exactly what it is.
i'm not alone then...
with cyanogenmod is so more evident...
tomorrow i'll turn on another one in my shop and see if is all xperia t like this...
anyway if some other has this strange problem, plz post here ^^ (maybe is a software fault)
Maybe a refresh issue?
when i scroll a page on black background with white txt.. the txt becomes greysh... if you scroll slowly remains white... happens to you too?

I don`t think it`s a refresh rate, but maybe i`n wrong.
And, yes, i have the same issues, and the screen is shading and becomes bright again all the time. Especially this happening when i try to open something or to enter at one of the bookmarks of phone menu, and when the phone "thinking", screen is shading, but then it becomes brighter again. I`m reaaly don`t know what it ies, but it`s not because of a thermal, 100%! I already changed the values of a brightness. I`m sure that all Xperia T phones are with the same issues, it`s bacause of a something in soft.
It has nothing to do with gpu.
Here is data sheet for AS3676 - www1.futureelectronics.com/doc/AUSTRIAMICROSYSTEMS/AS3676.pdf
And here is what DLS is from the data sheet -
8.4.9 DLS - Dynamic Luminance Scaling Input
The pin GPIO1/DLS can be used for dynamic backlight scaling input. Dynamic backlight scaling is used to reduce the power of the backlight especially when showing dark picture contents on the display. The control unit to operate DLS is the display processor sending a PWM signal to the AS3676 and in parallel changing the display content to compen- sate for a reduced brightness backlight.
DLS can be turned off in /system/etc/pre_hw_config.sh -
echo 0 > /sys/class/leds/led_1-lcd/use_dls
echo 0 > /sys/class/leds/led_2-lcd/use_dls
Is it save to turn DLS off ?

great find.. any way yesterday i turned on 5 new xperia t in my shop and all do like mine... that is DSL like peetr say..
but the annoying thing is that on cm10 (that all the ui is gray/dark) DSL is too much visible...) now i'll try to disable it.. i'll report if works
EDIT: still the same..
I don't get how to turn DLS off, what value should i change to turn it off ?

you must edit the file in /system/etc/pre_hw_config.sh
with root explorer or similar and change thise line: (0 instead of 1)
echo 0 > /sys/class/leds/led_1-lcd/use_dls
echo 0 > /sys/class/leds/led_2-lcd/use_dls
0 instead of 1 , and what should i set instead of 2 ? 0 too ?
And, is this save ???

Finally, this will have effect or no?
Because maybe we all have this issue.

this is stock
echo 1 > /sys/class/leds/led_1-lcd/use_dls
echo 1 > /sys/class/leds/led_2-lcd/use_dls
change in to this:
echo 0 > /sys/class/leds/led_1-lcd/use_dls
echo 0 > /sys/class/leds/led_2-lcd/use_dls
but i see no difference..
Dear all,
i had purchased new xperia sp, i am having some query
1. if i makes brightness to zero then also it gives some brightness
2. color combination is not correct
tell me what will be issue
thanks in advance
Azhar
What so u mean that u made the brightness zero.
Did u used the slider bar in the display setting.
If yes then it will not make the screen black as it is not practical.
And what do u mean by the colour combination not correct.

i had made brightness slidebar to lowest but its display is in brighter compare to other smartphone
colour combination is giving yellow shade in some sky looks

Different phones do different things - doubt it's a bug - you can install screen filter apps to further reduce brightness (I use one for phone use in the dark).
The orange/yellow photos that the camera on this phone takes is a well known feature of the SP...
Hi, I want to reduce the light brightness of my TX lower than that of manual. My rom is rooted LT29i 9.2.A.1.205 4.3.
I tweaked framework-res.apk
framework-res \res\values\integers.xml
<integername="config_screenBrightnessSettingMinimum">1</integer>
<integername="config_screenBrightnessSettingMaximum">245</integer>
<integername="config_screenBrightnessSettingDefault">60</integer>
<integername="config_screenBrightnessDim">1</integer>
But It doesn't seem to work. What can I do? If I need to tweak another system APPs?
The last line is what dims your screen before it turns off automatically. I suggest leaving this one the way it was.
Also, most likely these lines only work for manual brightness, not the automatic one.

Thanks for your answer:good: I just want to know how to reduce the minimum of manual brightness. I tweaked those values, but it didn't seem to work. I didn't change the values of auto brightness, however, The minimun of manual brightness is always brighter than that of auto brightess.
I think the drivers of display brightness are in the kernel
So your changes had no effect
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:
http://www.androidcentral.com/samsung-galaxy-s5-mini-review
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.
I would like to edit the screen's brightness settings
When i Looking through the ROOT BROWSER
Where is the thermalmanager.xml ?

I solved the problem myself
in etc
file sysmon.cfg
I edited there lighting values
So that the temperature does not affect the intensity of light
And it works perfectly
now when the device heats up the screen remains bright
There are entries starting from 51 up to 255
I changed most of them to 255
I lower and gradually decrease
