Kernel makers, please add the ability to adjust auto brightness.

Please add the option of modifying auto-brightness levels, like CM 6.1. I suppose that it would require a kernel modification + an app to do this through gui.
Thanks.

What can CM do? I've been thinking it would be nice to be able to modify the min and max, and maybe the curve.

It allows one to arbitrarily edit a table of sensor output vs brightness/button brightness.
It's really nifty.
CM6.1 reports these sensor values:
10, 160, 225, 320, 640, 1280, 2600, 10240
10-160 is in dimly lit indoors, 320-640-1280, in moderately to brightly lit indoors, and the rest is outside.
So I set those to brightness something like 50,60,70,80, 110, 140, 180, 255. A it was perfect to my eye. Not too bright, not too dim.
Didn't ever have to mess with brightness after that.

I'd really like to hear from developers like Netarchy and King, as well as from regular users - if they would like that option.

I would love to see this.
I always feel the auto-sensor tends to be too bright, and never adjusts the screen low enough inside.

That's exactly what I think. Plus, the brightness is not at maximum in direct sunlight (although that might be a safety feature).

Mine always send to bright, or it won't get bright when I go into a bright area until I sleep and wake it. :|

+1 on this. So motivated that I searched for this thread....

Any news?

The stock auto-brightness is way too bright in completely darkness. This is one of the things I had on my list nearly since the beginning. Nobody else seemed to care.

An article showing how useless auto-brightness is:

Do people not notice this or do they just not care?

Pretty sure people have given up on this. It's taken me three days of Google searching to find this thread so people probably don't know where to turn.
The lack of adjustments to the auto brightness values is extremely annoying. Even my old Windows mobile 6 phones had this ability.

There was an application for WM I used to use on my Mogul, cant remember what it was called but it allowed you to calibrate the auto brightness levels. Anyone know what I'm talking about, or if there's an Android version?

This can be done with Tasker in the Market. Its a powerful app and there was a thread a while back about this exact thing. I don't remember what it was called, but I posted in it, so you could browse my posts from a month or so ago.
Hey... This thing makes phone calls too!

[Q] How to change auto-brightness sensitivity

I want to change my auto-brightness sensitivity.
Im not talking about manualy changing brightness. I still want my phone to use sensor in order to regulate brightness, but i want every level to be a little bit brighter overall.

That's an coincidence. I was just searching the forum to see if a similar question has been asked... I've noticed varying min / max brightness levels on a variety of builds and I was wondering if there was something I could tweak to change those values (my goal is to get zero to represent something akin to "very dim" (not off), as the builds I've used over the last couple of months have been oh so bright.
Anyone know or point us to a resource that might tell us?

We have same problem and i havent seen anyone talking about this. I also noticed its different from build to build. And my latest problem is brightness is too low on recent build im using.
Any help would be appriciated from anyone.

Only thing I can tell you is CM6.1 based builds have those features built in, but I'm not aware of ways to do it for all builds.
JDMS has those features built in as well.

I wonder if it really is auto-brightness or just a kind of work-around. Looking at the ambient light sensor with the app GPS-Status, there are only two values: 10 LUX if darkness is around, and 160 LUX if any light hits the sensor. It seems not really precise...

[DISCUSS] Screen brightness sensor a joke!!

Sending this straight back, I cannot believe there is no option to disable auto brightness settings on this heap of ++++.
It has got a mind of its own and is extremely annoying to suddenly see the screen get dim and bright every 5 seconds without any change in actual lighting condition...it makes the phone almost unusable.
Hope someone can make a hack for this soon.

Yes, totally a reason to send it back, software bug on a phone with a unlockable bootloader. Hope your next one doesn't have any real issues

Maybe this was the software bug vodafone was saying?

http://www.google.com/search?client...rceid=opera&ie=utf-8&oe=utf-8&channel=suggest
sure you can't find a solution? It must be somewhere in the settings (I'm no android expert though).

It's not a "software bug", it's SE dictating to us that in order for the paltry battery to last a day, we need to use it in the dark, or disco mode!

well i report no such shinanigans happening on my phone! i can see the light sensor in action when i cover it with my thumb, it works really well and the gradient of fading and lighting up is the best i've seen on any phone so far! i dont notice it when using it normally.
you must have a faulty one....

Thought I'd mention that I have no such problem with my device.

I'm very happy with the screen. Especially good as I moved from a nexus one.

Can't you install brightness level from the market to controll the auto brightness ?

Wanna control your brightness levels quick and easy? I use a very slick widget called Dazzle. It has every option you can think of to control just about everything on your phone. Give it a try.

I don't seem to have auto-brightness, do have a slide in the settings to ste brightness though, on highest I can easely see in the sun and it hurts in the dark, on the lowest settings it's hard to read at night.
A Dutch review actually mentioned a lack of auto-brightness as one of the downsides to this device.

It does have Auto Brightness as if you put a finger over the light sensor the phone screens dim.
The phone had an update pending the day I purchased it so most of the reviews I have seen are out of date. This phone is excellent at playing games.

I hear that. In love with my Xperia Play.

Guys can someone tell me. A lot of reviews say that the screen is very dim even on max setting and a lot of reviews say the exact opposite. So what is it?

Mine is perfect in the sun. I'm starting to think there are 2 types of screens involved, anyway to check what screen you have without opening the device up?

Screen brightness is ok for me, but just remarked the display have some ghosting issues. Slide beetween programs screens and observe carrefully the icons.... with red "Adresse" one this is very visible. i can't belive sony use a high response time display on a gamer device.

Gpad screen gamma is too low

Some of you may have noticed it's difficult to watch dark scenes in movies on the gpad. I think the problem is the gamma calibration, you can see it clearly on the pictures I took.
https://imageshack.com/i/nf96iaj
On the top you can see my nexus 7 2013, you can differentiate all the shades of grey from 1% white to 100%.
On the gpad, everything is solid black from 1% to 12% of white.
You can find the original image here : http://imageshack.us/f/594/6291.png/
How low can you go, on your gpad, before the grey melts with the black ?
Do you know an app to apply gamma correction ?
Here you can see the same picture on the N7 and the gpad. You can't even distinguish the guy's ear on the g pad.

I see the difference, and I knew it was there already also.. I'm sorry, but apparently gamma is not something that is doable. - I was looking to link you the app from market called "Screen Adjuster", however you want to look at this description, especially the last sentence. ;/
- dimming the screen 15-100% (below minimum system brightness)
- screen color and a contrast adjustment
- system brightness 0-100% adjustment
- functional widget (on/off, system brightness, settings)
- autorun option
Some phones have a color tint screen. This app have a possibility to try to improve colors on this kind of the screen by setting an additional factor RGB.*
The range of the dimmer is from 15% to 100% (it allows to dim the screen below a min system brightness value). Make a relief for your eyes during a nightly reading.
Furthermore, you can change fast the system brightness too.
The additional contrast factor can try to make the reading or a picture viewing more comfortable on some screens.*
The widget provides fast on/off service with a shortcuts to the Adjuster settings and the system brightness settings.
The application has the autorun option which works with the dimmer set above 22% (for the safety).
Note
A gamma adjustment is not possible to do.
You can of course try and download the app anyways and see if contrast or brightness will do anything for ya.
- In case you do download the app, remember that setting contrast low will result in problems with installing apps, as in you cannot hit Install, only cancel. To avoid this, open up Screen Adjuster and turn it off, install the app and turn it back on afterwards. It's something about lowering the settings to lower than what is "intended", I don't quite understand it and I find it rather odd. But it let's you install apps.. So I guess hooray.
That's all I got.

Thank you for your response, but I'm already using screen adjuster. I set the contrast at -25 and it helps a lot to see dark details.
Unfortunately, it has two side effects :
- it brightens the dark shades of grey, but also the black levels.
- I noticed that the contrast setting also affects the white making it look like light grey.
So the contrast setting in screen adjuster doesn't affects only the dark tones like it would on a monitor or a tv, it affects the contrast ratio.
I've found apps to make gamma adustment but it only works on some devices with custom kernel.

Yea, I was about to say that gamma can be done but only on custom kernels. Lot of Nexus 5 stuff on the market. Apparently it's Google who locked the gamma settings completely down but only in 4.4.2. I guess it may work on stock LG Kernel since it's only 4.2.2? I'm afraid we'll have to wait for some kernel support for other roms. That would be awesome. I really hope for some Franco-kernel-glory on this device.

That's what I thought, we need to wait for custom kernels...I hope it will come soon, because it's so frustrating to have such a good screen with bad calibration !
People tends to complain too much about the warm white balance but the gamma calibration is far more concerning.

Hi there Young Bobbie, I am new to posting on XDA so I couldn't post this in your kernel developer page. This is my first post on any forum page ever. First off, thank you very much for your hard work to make this kernel happen to correct gamma on the v500. I have been sitting on the fence whether to get the gpad, and if i would get the v500 or the v510. Was leaning toward the v510 because of Sleekmason's wonderful kernel work, but it's exciting that we have now have the same options available for the v500. I noticed this was working fully with the Malladus ROM. My question to you was whether or not this worked with stock LG ROM as well? Thank you again YoungBobbie and Sleekmason for your time and creations.

Not sure if anything there can help, but I know that the sharpening is applied when there's something light on a dark background or vice versa and also if you have any type of floating menu it'll sharpen everything in the background.
Samsung does this as well but as far as I know only in multi window mode.
Its not a screen issue as its not always apparent. And as far as I know the oppo find 7 has the same panel and doesn't exhibit these effects.
So anyone have any ideas?
Kernel related ?
Display drivers?
Maybe we should all email lg and ask them for an option to remove it.

Just fyi oppo use japan display inc panel while lg use their own panel

I think the only way to defeat the sharpening is with a custom kernel and possibly an app to tweak the display unless LG of course turn this 'feature' off in the future themselves via an OTA update.

Hope they do. Its pointless.
So anyways I came across another thing.
If you tune the display with a kernel app as in colors. If you tune all the colors down and make the colors darker and such, everything will have the sharpening applied. So it seems like the software sees that and applies it to everything.
Hoping it's just kernel

I am just guessing as I am not a developer by any shape of the imagination but this sounds like it's built into the OS so possibly a tweak to prevent this behaviour from getting triggered which will turn off the sharpening effect.

When it finally rolls out to the USA then I think it will get better dev support.

I'll have the device soon, but I'm not sure we're able to turn it off since it may be the part of the driver. Haven't done it yet, but if we can debug the running code and binary patch the trigger effect into not signaling, we may fix it. If it IS a trigger at all; e.g. we should find when it does signal the driver/gpu to apply sharpening and just switch code from JE to JNE or similar to kill the trigger and never apply it.
Theoretically.

Hopefully LG can turn it off and not a hardware combo issue with the 801 and this particular display tech.

The purpose is either, they want to emphasize the need for it so they make things extra sharp over 1080p not realizing it actually looks worse when its sharpened. Or its because the contrast ratio is low so to do that they sharpened it in areas where it would be more noticeable to make it more legible. Again, doesn't really help.
On the galaxy phones it would produce this on multi window mode as stated and when putting a cm ROM on it you wouldn't get any of that since there's no window mode. But... If you go into screen settings and change the screen aliasing type or whatever, if you change from standard to reading mode it would make the display sharp exactly like we see on this one. So once we get kernel support for screen modes (cm adds modes such as movie mode and sharpness ect) then we should be fine.

Well, I don't believe a whole bunch of smart engineers, designers and such in dev and QA would not notice it sucks...
And for screen modes, after so much hassle, I hope and expect LG is preparing us a "turn bloody thing off" setting...

Well once it comes out in the states I will be contacting some devs about it. We need a boot loader unlock as well though

Without seeing it in person, it probably was added to make their simple UI have more of a pop to it. They were probably trying to make it stand out more in stores, like how tvs usually have horrible settings when on display at a store.

They're dumb because it makes it look worse. In almost positive a fix will be found. If anything maybe the carrier releases will have this fixed already.
