LG 8.3 Screen Temp Calibration - G Pad 8.3 General

This may or may not work for any of us but I thought I would like to share and point some people in the right direction.
savoca over in the G4 forums posted this daemon to run at start to adjust the screen temps.
http://forum.xda-developers.com/g4/orig-development/kppd-configure-post-processing-settings-t3165247
I am not sure if these work on other LG tabs but it seems like it might. I know my new LG X8.3 has a VERY warm red temp and drives me crazy. I have to crank up Blue like 50% and Green like 25%.

Overclocking.

Ooo. Such a scary word. Is the G1 a potential candidate for overclocking anytime soon using the SDK? Also, does anyone else's G1 heat up on the backside of the chin area? It gets pretty warm down there.
yea mine gets warm in the same place if i us it a lot or if it on the charger for a while.
There was a discussion between a dev and a Google Android employee on GoogleGroups quite a while ago where they explained the warmth is normal + o/c-ing would not have a noticeable effect. Will try to find.

[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!

and apps force closing are just the man keeping us down!
... unless the sensor it's self is dicked, then it can be fixed in software, even if it is dicked, it can be completely disabled.... just cool your jets.
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....

They have to stop the complaints some how, at least the speakers are not gimped
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.

[Q] Adjust screen bightness

Hi everyone!
maybe you noted that the lg screen is too bright! even in low setting it is almoust unusable in the dark (night)!
Is there someone who knows a way to change the value of brightness of the presets (maybe a regystry tweak)?
I thinks it will be usefull for a lot of people. . . thanks for the help!
I find the low setting to be... quite dark.
Perhaps try setting your theme to Black instead of White...

The low setting is dark in a bright place of course. But if you are in dark, the lowest set for becklit, is too bright. I'll post a link with technical conparison between screens.
here is the link with some data:
http://www.anandtech.com/show/3982/windows-phone-7-review/28
I'm bothered by this too. Does anyone know how to set it to a reasonably low value, so that text can be easily read in the dark? (white text, black background)
I found something in the registry related to brightness, but it seems to be already set to the lowest value (0).
HKEY_LOCAL_MACHINE/Drivers/BuiltIn/Backlight/MinBrightness

Have you tried setting it to a negative value?

Just bought it,and i noticed this too high brightness too...any way to adjust it?
Same here. This is really starting to bother me...
I've already tried messing around with several values in the registry values with no luck... I suspect this can only be solved with drivers and/or firmware. Maybe if enough people complain about this they will change it in a future firmware?
Lg can solve the problem

Exactly! I phone my local support and said this and they were really happy to have a customer feedback.
thay said that they are collecting suggestion and than they will evaluate for a firmware update...
maybe we should suggest to implement autofocus (or prefocus at least) in video too!

Done.
They told me no one had reported about this issue yet, and that they would call me back somewhere over the next few weeks, after their engineers discussed it.
In other words, we need a lot more complaints to achieve this...
(Bump)
Out of curiosity, has anyone else done the same? Several people complained here, but this topic is now suspiciously quiet...
You guys sure you don't have the Automatically adjust setting ON?
Stupid question I know, but I need my 8 posts to post links for my mini PDAir LG Optimus 7 Aluminum case review.
Agreed the LG screen is ridiculously bright on both the Lo and Automatic setting in darkness.
I can't use it in bed as it lights up the whole room, and it causes far too much glare in the car at night so no good for SatNav etc.
Surely it would be better for battery life too if the backlight wasn't burning a hole in my eyes!
Data from link above. Obviously LG need to recalibrate their presets:
Brightness Comparison (White Point)
Phone Low Medium High
HTC Surround 10.4 nits 183.1 nits 405.7 nits
LG Optimus 7 130.4 nits 259.1 nits 381.2 nits
Samsung Focus 61.9 nits 143.1 nits 234.3 nits
LG Service Sites - email your local office to request a fix:
http://www.lg.com/global/supports/service-sites.jsp
Don't know if they will bother fixing this on the E900 (here's hoping) although you would expect it to included in the refresh Mango E906?
Did anyone of you use the amazon Kindle app on lg optimus 7? You can adjust the brightness so damn low within this app...

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.
Sorry, just answered my own question. Guess it helps to read the very first line of the page (making fun of myself now ;-P) Thank you again YoungBobbie and sleekmason!!!

Gald to have helped would you be willing to try the kernel for the stock LG ROM?
Please take a look at the images below and compare
The tablet on the right is running my kernel and the left stock
You can see the differences on the first image as the deepness of the blacks
and on the second the highlights on the white

[Request] Get rid of screen sharpening from LG V20 kernel

The sharpening effect on V20 is less aggressive than on LG G3, but I still find it unpleasant to look at. I have very high hopes that this community will be able to fix it by removing the effect altogether.
Here is a link to LG G3 thread about a successful fix: http://forum.xda-developers.com/lg-g3/orig-development/fix-stock-kernel-oversharpening-fix-t2951620
Here is a link to code commit containing the fix for G3: https://github.com/Skin1980/D855-kernel/commit/74f033f5798b35a491c7fabd2767a6c0e785d788
Thanks in advance!
Wrong section.
Can you explain, or demonstrate what you mean by screen sharpening?
Nvm, I just saw it. Doesn't seem to be prominent at all, let alone noticeable.
I'll try to poke around with the kernel, but I can't guarantee anything since I am so new to android cooking. Also, I am still working on fixing FM+bluetooth in my kernel, so it might not be til January until I try. Maybe sooner if I get some time off.
