[22FEB2012] [FIXED!!!] Custom Auto brightness with flashing LED (Read First Post)

We have a fix​
Please read this post (and Thanks Milaq for the fix!!) and follow the instructions.
[*]Also, can someone test custom auto brightness levels too please?
I have made a ClockWorkMod flashable version of the fix in this post. This should cover almost all ROMs, irrespective of how the device is named in build.prop (leo, htcleo, bravo, qsd8k).
Original Post:
UPDATE: Thanks to Looki75, we have a workaround using Tasker to have custom auto-brightness levels with the flashing LED libraries here. Please go through his post and give your feedback!
I am rewriting the whole post, based on what I realized/ learnt today
We currently two lights libraries for to our phone:
lights.htcleo.so - this file has working auto-brightness and flashing LED notifications - but custom auto-brightness settings do not work (more on this a bit later)
lights.qsd8k.s0 - this file has working auto-brightness and custom auto-brightness levels, but LED notifications do not flash
Custom auto-brightness settings
What is it?
This is a setting/ feature in CM7 ROMs, not sure if MIUI has it or not (Users, please confirm if you have custom auto-brightness settings in non-CM7 based ROMs)
In a pitch dark room, the screen's brightness chosen by auto-brightness setting may be higher than required. With custom auto-brightness, the level of brightness the phone uses for a specific amount of light can be configured - the biggest benefit being higher battery life. Please read this post by @Dorimanx for custom auto-brightness levels.
How do I know if I have it or not?
You do not have the lights library that is compatible with custom auto-brightness levels if:
Your LED Notifications work (Except HeirOS kernels)
If you have something similar to this in your logcat:
20:50:43.090 Error lights 180 ***: value=90 (Mode=1)
20:50:43.090 Error lights 180 ***: value=91 (Mode=1)
20:50:43.090 Error lights 180 ***: value=92 (Mode=1)
20:50:43.090 Error lights 180 ***: value=94 (Mode=1)

On the other hand, you have it if
Your LED does not flash
Your screen will dim for several seconds (5~10seconds) before timing out
You do not see the errors I had quoted above in your logcat
So what is the point of this thread?
I had tried several Kernel combinations (and libaudio.so, but that does not matter in this issue) while trying to figure out the No Sound/ BT Voice Command/ libaudio.so issues, and found out that even if I have lights.qsd8k.so, which enables custom auto-brightness levels, LED Notifications flash with HeirOS 1.7.5 Kernel - they flash in amber and green alternatively. This gave me a hope that
This is something to do with the kernel (I used Tytung's initrd.gz, so it is not from there...)
This could be fixed easily with all our kernels, because HeirOS has already done it!
So What Next?
Anyone using any of the HeirOS kernels see what library you have (/system/lib/hw), and please use the lights.qsd8k.so if it is not there, deleting lights.htcleo.so while at it (it is available in the Mirrors used by @Dorimanx), and confirm if you concur with my observations - please mention the kernel version and the name of the lights library in your feedback.
Once we have that confirmed, we can request HeirOS to let us know the secret ingredient (or someone intelligent enough to look through the source codes can find it and post the diff/ findings).
This is not a critical/ experience-affecting issue, but rather something that is now "broken" and can be fixed without much ado!! I am sorry for not being clear earlier, a little bit of Rum cleared things up for me
Lets now restart this discussion!!!

It is people like you that are going to make our phone as if it came with android when we bought it! I know you are not the one doing the coding but with all your support, your don't give up attitude, and your connections you get the job done. Thank you for all your determination.

hopefully the next thread for collaboration work that will become one of it's kind in hd2 android history. thx for your dedication and all the testing that you do! thanks to all the devs making our hd2 improving everyday.

I have posted a request in HeirOS' kernel thread, meanwhile can those who use earlier versions (1.7.2 or so) confirm if they have working LED Notifications when you use a working auto-brightness configuration please?
If so, I think we can trawl the source code posted on the first post of HeirOS kernel thread...

Had never problems with auto brightness and my last kernel with a non working LED notification is older than around a half year. But I tried only MDJ, Tytungs and Raf's kernel. Green and orange LED are working perfect with these.
What problems do you have with auto brightness? Not working or the false brightness for the actual light?
Only outdoor at sunshine the auto brightness sometimes didn't choose the maximum brightness, than I set manual to max.

The auto-brightness / LED notifications are from /system/lib/hw/lights.htcleo.so (or lights.qsd8k.so).
In our case if your ROM's chef chose to have a working LED Notification configuration, auto-brightness will not work - the display will have a fixed brightness irrespective of the surroundings, and will not dim before fading out.
If you choose working Auto Brightness, the screen will maintain ambient lighting, but when have a missed call or SMS or email or chat, the LED stays on and does not flash.
That said, what kernel are you using? And can you check your logcat right from system boot (using QtADB?) and let us know if you see any errors?

Yeah...
Typhoon included Led blinking, i always replace it with lights.qsd8k.so with auto-brightness, i dont care about Led blinking too much, more interesting good working auto-brightness

Install led me know from the market and you will have both working fine.That is what i do in dorimanx rom which has auto brightness enabled by default.

If I remember it correctly, the working LED Notification (i.e. No fading out feature) of lights.htcleo.so in my GB ROM is from Gpc.

Moreover I think that the developer of LedMeKnow app, which is free by the way, may point out to the developers what to change in order to have both auto brightness and led blinking working out of the box for hd2s

leds and auto brightness work perfectley if you use the lights file from iamgpc. So I dont see the problem. Secondly this problem is hard to catch I can remember that Letama and gauner1986 tried to solve this problem but at the end they gave up.

Yes, manual brightness works in GPC's lights.htcleo.so, but auto-brightness does not.
I found the HeirOS has fixed this (though not documented) in 1.7.5 (not tested earlier versions)...

ph03n!x said:

I am saying "most" because in my quest to fix the No Sound/ BT Voice Command/ libaudio.so issues, I tested various kernels and configurations, and found that with HeirOS 1.7.5 kernel, I have a working auto-brightness WITH flashing LED notifications. The notifications actually flash amber and green.
So looks like this is something that we can fix easier than the close to 5 weeks spent on the No Sound bug
HeirOS, please share your thoughts/ inputs for the benefit of all of us!!

Like I said earlier, while fixing it natively is a good-to-have solution, and not a deal breaker for almost all of us. But still having it fixed surely feels good, doesn't it?!!

LED Me Know eats up battery while flashing notification. When its flashing LED, the battery drain is more than 100mAh. Though I haven't used the application in a long time, but I remember previously it used to do that...I wonder if its changed now..

I actually prefer a static LED with working auto brightness.
Its very obvious without staring at my phone whether I have a new text, missed call, or otherwise. I tend to miss the blinking since its 8 seconds apart.
(know it can be configured to 3 seconds, but still)

Auto brightness works fine here.

In HeirOS 1.8 kernel i have led working and i do notice that when its really dark the screen will get bright and when its super sunny it gets darker so i believe auto brightness + led works fine in his new test kernel btw i am on sense gb rom.

Auto brightness with flashing LED notification works perfectly in Tytung's rom and kernel.

[Tips] Screen Color Calibration for the Galaxy Nexus

After using the Galaxy Nexus for two weeks, I found the screen color of the new amoled+ is much better than the Nexus S, but still inaccuracy. I'm a part-time photographer who keen on the right Gamma, color accuracy and color temperature.
So I just finished some test with such things:
Galaxy Nexus
franco Kernel 18.5 nightly(with the ColorControl from Ezekeel)
Voodoo Screen Test app
x-rite i1 Display 2 color meter
HCFR software
The test result was not so good...
Average Gammar value is about 1.9, far from the ISO stand 2.2. So the color is just too bright (I'm not saying screen brightness).
The shadow part (0-40% gray level) of 3 color curve were almost out of trim. In another words, incaauracy color balance.
As the color unbalance. The color temperature is starting from lower than 5500K to 6500K, which the ISO stand is 6500K at any color level.
I also tested the ColorControl in franco Kernel. After the adjustments, Gammar value is still bad, but I save the (most part of) color balance & color temperature in the end.
The adjustments step by step:
Make sure you have a rom/mod with /init.d autorun function.
Bye, stock rom...
Make sure you have a kernel with ColorControl function.
Such like Ezekeel, franco...Else? I don't know.
Set the screen brightness to 50%.
It's the mesurement "baseline". But why 50%?
Because, at this point the screen has a brightness about 120 Lux--also a ISO stand. So, it's very close to our desktop LCD.
Make a new file as /etc/init.d/900colorcontrol-b50
Which could be done by Root Explorer or adb.
Inside the file, type such line:
Code:
echo "-10 0 -10" > /sys/class/misc/colorcontrol/v1_offset
echo "1820000000 1900000000 2000000000" > /sys/class/misc/colorcontrol/multiplier
I choose "182 190 200" here, because the default value was about 200. Rising will increase the risk of LED Burn-in.
And, don't forget the 7 zero!!!
Just reboot & enjoy the almost right color temperature.
It's (6500±300)K at any color level in my device. Not perfect, but much better indeed.
Done, that's all I can do for you.

Thanks so much for the mod.
I'm willing to test your new calibration for the GNex color but how can I revert back to stock in case of problem ?
So I guess we can only use this modification at 50% of brightness ? If we change to auto, how could it be ?

Sorry for being a noob here, but this is compatible with any rom/kernel right? I'm currently running on AOKP Build 25 and Popcorn kernel 7.1
Thanks,
Mosh

Hi, and thank you for offering your expertise. I'm not confident in doing the above.... Can you offer a little bit more step by step?
I've played around with root explorer which I imagine is what is necessary to change these values.you lost me at the 2nd step.....
Also, is 50% necessary?
Thanks kindly,

You can change all of these settings from Franco's kernel updater program directly without modifying any files.
The OP's settings appear a little warm at first but I'm liking them so far...

Can you please add this file 900colorcontrol-b50

sooooo do i make a folder in system like this?
system/etc/init.d/900colorcontrol-b50 and then add that text above or??

Instead of making that script, can we just input those numbers into the Color Control?
-10, 0, -10 for Gamma (RGB);
182, 190, 200 for Multiplier (RGB)
Right?

Thank!
your feeling about color is exactly. Gray is dirty, it's not sync at all pixels.
I hope someone changes this by kernel - easy for me control everything
After flash franco kernel it's better more but not perfect.
If this problem is not improved, i'll buy other phone that uses Superamoled PLUS replace this one . HIZzzz

These settings look green to me

Indeed... especially settings menu looks very greenish!
But maybe I get used to it...
Edit: Maybe a typo? '-10 0 10' looks not that bad at all ;-)

And that would do absolutely nothing
SAMOLED Plus displays are identical to the SAMOLED HD displays when it comes to colors and such.

It would be better and more easy if someone was able to do an app like this one that works for the Nexus One :
http://forum.xda-developers.com/showthread.php?t=745248
I really miss this app since I've bought my Galaxy Nexus

Thanks for the info. I had mine looking very similar but with a combination of lower brightness and higher multiplier values. Nice to have it set now without the additional risk of burn in. Thanks a ton.

screen looks greenish compared to franco's recommended value, using his instead but thanks for the write up.

Peoples rom v 2.2

I am running a clean install of peoples rom v 2.2 on mtd. At around 15% battery life, the phone shuts down as if its completely dead. I restart the phone and it shows around 15% battery. Any ideas on what's causing this? I have had this happen on a few roms now, also happened after about 2 months of running the clean gb rom. Another issue I am having is on certain apps, like facebook or gmail, when I open the app, my screen flickers as if I am having a loose connection inside my phone. Doesn't happen on every rom, but its happening on this rom. And last question, my wifes epic 4g keys do not light up anymore on her physical keyboard. Tried different roms and even stock. Still no lights. Any help? Sorry for the lot of questions. Thanks for the help in advance!

#1: Search for threads on battery calibration, or look in the People's thread for Kenny's method. Some say it works, others say no, but YMMV.
#2: Settings in Voodoo color too low. Use Voodoo control to adjust until no more flicker.
#3: Hardware issue. Take it to Sprint.
EDIT: Here's the settings I use on TPR. No flicker and looks awesome.
(Don't know why his name won't show, but credit goes to marcusant)
I have tested these settings on a personal kernel with mdnie disabled.
These should look fine on cm9 on most if not all kernels.

If you get screen flashing, increase v1 values a bit and decrease RGB.

What rom are you using... what kernel etc..
On maximus with stock kernel I barely get heat...

Your comparing a DHD to a One X.... It's a quad core device *facepalm*...
So before you give up and call the One X a terrible phone (like the 500 rants this forum has) . We need much more information about your device.
1. Have you unlocked the bootloader?
2. Are you running a custom rom/kernel?
3. What base are you on?
4. How long have you had this phone? And how long have you had this problem?

If the screen becomes yellow due to the heat, I would say this is hw problem as he tested different roms. UV might help, but the device should not become like this.
What I would be interested in, if he is not using it in direct sunlight on a beach with 40 degrees in the shadow. Even though I saw ppl say their devices survived that.
I am now in Egypt myself and even at night. With -125 UV. And the device still gets hot, red/green blinking on charge.
BUT I never got yellow spots coming out of the screen. And just cuz of that I would says something is wrong on hw level there.

try faux kernel and undervolt it and underclock it using system tuner or setcpu that will solve all your heat issues

I have exactly the same problem. Whenever i use my One X for navigation in the car (using Navigon) the battery drains more than the Kidigi Car Holder can charge. I already checked all advices that there are like:
- Kidigi Car Holder is charging with AC
- disabled 2 Cores
- UV all frequencies by -125mV
- running the phone in airplane mode
- disabling autobrightness
At the moment i´m running ARHD 9.3.2 with Faux 007m Kernel.
Could someone please help?

If it's happening on 2 roms other ones won't help you.
For sure not customized sense ones.
You could compare sense vs cyanogenmod.
But still, the CPU is kernel controlled.
And remember always when you download a Rom it takes like a day to settle, syncing set ups and etc. So to test a Rom you need few days.
Just stick to a Rom for now. And try the advices we already gave you. Undervolting with lets say faux kernel etc.

Install Hidden settings app from play store and in the newly created Power saver settings in the app drawer, disable "Reduce CPU cores" or something like this,(its the second option on the list, thats for sure )because basically your HOX runs on 1 core with 1 Ghz, but if you turn this power saver setting off, you will have a full 4 core perfomance, as it should be. This has solved me the heating problem a long time ago when i SEARCHED THIS FORUM, which option i gladly reccomend now to you!!!

im going to test this way tonight and will tell you any updates :fingers-crossed:
thanks a lot

I have this problem too, i have try this app but still overheating....
Sent from my HTC One X using xda premium

with faux kernal and hidden setting my hox doesn't heat up like before
only once heat up when i force close some apps
but still much better the before :good:
i still want the value that i must change in system tuner
also i notice in system tuner the CPU didn't change at all
waiting for the values

try other roms
Before I face the same problem but after I change the ROM to rd miui, I think the heat still natural for me..
My advice try rd miui for ICS or jelly bean and try cm10 from trip droid ROM with new kernel 3.1.10 for jelly bean.
Now I am still try using trip droid ROM..so far so good about the heat..
Best regards
Ronny tri

Im glad i could help. In system tuner at the voltages tap ONLY 2 Times the "-25mV" icon, and at the cpu, set the governor to interactive. I guarantee your HOX will freeze your hands while you're holdin It

[Q] Possibility for Future Screen Improvement?

Today is the very first time ever for me to root an android device and thank God it run perfectly.
Now i am using AIC kernel for V500 4.4.2 stock ROM. (http://forum.xda-developers.com/showthread.php?t=2741405)
Gamma correction in it really improved screen and picture quality. (plus 8000 antutu point increase bonus)
Before, i can barely see anything in Bloodborne trailer video. (http://www.youtube.com/watch?v=G203e1HhixY)
Since i cant post in development thread, i hope i can find answers to the followings:
Is it possible to further improve gamma in the future?
Even though currently gamma is improved, but the brightness level issue still persist. Is it hardware or software issue?
Is there any possibility for brightness level improvement in the near future (kernel) update?
All in all, i really like my G Pad and really hope for the possibility to receive screen improvement update in the near future.

I heard a week or so ago through the grapevine of a version 20d coming out pretty soon. I have held off making any other changes to the AIC kernel until I see what LG did(no sense reinventing the wheel).
What brightness issue would you like changed? I know in general people think the Gpad screen is dark, but some of the AIC kernel users think the lowest brightness is too bright as well.
I think the screen is pretty bright at 100%, so for me it's a software issue. That's in 2 places, the kernel backlight driver, and the ROM brightness(think brightness slider).

Tks for the reply and also thank you very much for the kernel, it really is helping a lot!
Rather than issue, i should have worded it as G Pad having a relatively low brightness level/dim display.
Compare to my nexus 7 1st gen, G Pad at 70% brightness level still not as bright as nexus at 30%.
Actually i dont really mind it, 70-80% G Pad brightness level is my sweet spot.
However, it would be great if the number is 30% rather than 70% (i am just feeling paranoid of having big number for a display setting).
I also realized that colours (might be) a bit off, especially red that looks orange-ish.
In general display seems lean toward yellow (yellowish-white).
Wonder if this is a common thing for all unit?
Hopefully it is just a matter of colours calibration that can be solved through software update not a hardware characteristic.
I tried Screen Adjuster and added more blue and red, but i just cant seems to find the proper setting to create a whiter white or redder red...
All in all, it is nice to hear version 20d may be coming soon.
Hopefully LG will address all these screen related things.
Also, really look forward to your another great work, especially when LG get it all wrong again this time

It would be great if you could add row scheduler when you next update your kernel.
Thanks in advance rich ?

You can use Faux Clock or System Tuner to adjust the color temp and gamma.

Really...?
In that Kernel thread it states....
Add Faux Display interface (gamma control seems broken)
so does the Faux app control the gamma, even though aicjofs had noted that it seemed to be broken...?

Pardon me but where can i find this Faux Clock and System Tuner?
Do you have any preferred setting for optimum screen (colour) performance?

You can find them here https://play.google.com/store/apps/details?id=com.teamkang.fauxclock and https://play.google.com/store/apps/details?id=ccc71.pmw.pro . Your best bet is to either use a calibration tool or just adjust it to your eyes.
