[DEV] Exynos Galaxy S II Screen tuning app - dev. snapshots discussion

Hi Galaxy S II users and developers!
I'm working since months on Galaxy S II Super AMOLED+ screen calibration and rendering customization.
As it takes a lot of time to get something really usable, I decided to publish dev snapshots as a free application on android market.
This project takes so much time because I reverse-engineer all the mDNIe image converter registers one by one. Same for the ld9040 Super AMOLED+ controller.
Then I measure the potential effect of settings found, transform it into comprehensive settings etc.
I also back-up all this by measurements made with a calibrator.
Most of this reverse-engineering will be published as GPL source code.
I don't provide any kind of support for the dev snapshots but I'm sure you'll be interested discussing screen stuff here.
Icon chose is self-explanatory: unstable software!
I have ambitious plans for this application. It may become more powerful than anything you saw before affecting screen rendering on any mobile device

I've installed the Market version but can't see differences between the Native and Samsung mode.
Same as with the earlier version you distributed on Twitter. I've read there you said it worked only on your SGS2. I guess it has been fixed now but still, no changes for me.
EDIT: I see a change now between the 2 modes, my screen mode was set to Movie, not Standard. And I remember having seen in the app you change the Standard mode settings only. Maybe worth adding it to the 1st post?

I was also using the movie mode but sometimes the screen will became a little bit greenish.
I'm so happy with the screen Turner now especially with light blue!

exciting only things i hate after switching to sgs2 (from i9000) was color calibration (and banding issue) and a bit sound quality which can be increased even though its not that much difference..
@supercurio do you have something in mind about color banding or its just calibration?

Nice start supercurio!! Happy to know you have started working All the best

thanks for the early feedback:
@snark_be as its really dev snapshots, I won't document it as virtually anything can change from one day to another.
Thats why sharing your observation with other curious experimental testers is so valuable

As someone stated before, I got good result against light blue colours...

Color banding: mostly done already.
Disabling artificial sharpening on everything make any banding very hard to notice.
Still, some apps are runing in 16-bit mode without dithering on MALI GPU instead of 32bit as you can see in Angry Birds RIO introduction animation.
Samsung settings apply sharpening even on dithered images. Result is not good, as expected.
The gradient pattern in today's app show that.
Gradient itself is a screen screenshot of Samsung browser rendering, for an accurate simulation.
The app will be declined for power-users, allowing full control over all the settings.
Sharpening, color saturation or tones: its all a matter of user preferences.
For Calibration I'll work on linear domain, directly tuning AMOLED hardware and not mDNIe effect.
Its what allows the best precision and avoid ending with 7 or 6bit usable per channel, but due to how is supposed to work factory calibration it's also the only way to fix color calibration issues, that makes some screen very different from others in terms of white balance, especially in low brightness modes.

hi
i tried tune it but it doesnt work.
When you look at letters ex web you see bluring letters. I discovered i had the same problem on windows 7 but switch of smooth edges of screen font and font are sharp crisp. Take a look http://forum.xda-developers.com/showthread.php?p=15554743#post15554743.

Yes, everyone eyes gets lazy when used to a sharpened result.
Immediate comparison makes the normal rendering looks blurry even if it's not − brain trick!

Maybe you just don't like Android font hinting.
Personally I prefer stronger hinting like freetype "Best Contrast" one available on Linux desktops.
Issue with this kind of string hinting is that it doesn't play well with arbitrary font size.
Shapes become 1px or 2px wide but nothing in between, probably why Android uses an intermediate hinting, that eventually works better on higher density screens.

does this only work on stock based rom? are you planning to get this working on cm based rom as well?

It will work on CM based ROM when they'll re-add mDNIe support in their kernel.
mDNIe feature doesn't depend on kernel patches as Samsung nicely allowed customization in their own driver.
Of course this official driver must be enabled (CM) and not destroyed in its functionality (hardcore's patches)
I discussed it with Unhelpful and codeworks a few days ago and will contribute if needed.

Edit : seems to work, even though difference barely is noticeable, I guess it'll improve with updates

this may be a solution of fixing the left side yellow tinted screen just like mine

WOW~~supercurio you are come back again~welcome! just installed it from market~
native mode seem look soft and warm ..i like it..
samsung mode look dazzling and cold..
but i think it's a long way to go...
but i am very happy..you are back...
because i love your voodoo lagfix voodoo color voodoo sound for SGS..
also hope you can bring some things for SGS2~~

Says this device is not supported, running CyanogenMOD7 ver 31

Incredible difference. I really hated the sharpening Samsung do. Cannot thank you more for your hard time put into this.

This has potential to be a major breakthrough for SGS2 phones. Modifying our displays to fit everyone's needs is a much needed addon.
Thanks Supercurio!

Rant about hardcore users, productivity and the Sense launcher

There are some things I can't get my head around.
From the screenshots of all the cool user ROMs and themes available it's clear they've been designed by clever people who use their phones a lot. So why does it appear from these shots they use the Sense launcher, and their default home screen has a big Sense clock and hardly any apps?
Presumably, like me, these people are pulling their phones out their pocket and putting them back there many times a day. Presumably also, like me, these people use a number of apps and widgets in a day that hits two figures. With this in mind, I want to be able to get to those apps and widgets easily and quickly. I.e., with as few swipes/clicks/screen presses as possible. I'm sure these people do too, right?
So that rules out the Sense launcher doesn't it, with its 4x4 grid limitation and non-resizeable widgets. Not to mention its time-consuming spin-in carousel effect every time the phone's security screen is unlocked. I haven't found anything useful the Sense launcher does that another launcher can't, at least after downloading other apps.
Furthermore, who really keeps that big clock on their home screen, when 1. you probably wear a watch; and 2. you can see the time on the top right. It seems like a silly amount of screen 'estate' to use.
Or is it that these people in fact have a more practical default home screen and it's just tradition to post the screenshots they show?
Finally, why do so many of these otherwise brilliant ROMs not mod the battery icon to show how much battery is remaining, percentage-wise? Appreciate this can be modded using the kitchen website. But surely everyone wants this info from the off, so is it not included?

Well, I'd never call myself a hardcore user - although I believe that term should be defined too, because I'm not sure it's interpreted the same way by everyone. That aside though, here's what I think on tinkering with the launchers. You buy an Android phone - be it of any manufacturer. In general, and especially considering the top level models, it can be said that there isn't much diversity hardware-wise. What does make a difference is the UI, the services integrated and how the phone handles them. (And let's exclude synthetic benchmarks for now, I don't believe they represent real-life scenarios.) So, someone knowledgeable going for an HTC device (meaning it's not chosen because of price or because of how "pretty" it is), imo, means they're attracted to Sense: those little nuances that do make the difference. Ditch the launcher and you've pretty much ditched at least about half of what Sense - of what HTC is about. But then, why did you go for HTC in the first place? And the same can be said with Samsung and SE as well, those who quite heavily modify the Android UI. Sure, you can do it, you can dump the whole customized everything...but can doesn't mean that you should: if you're a "hardcore user", however we define the rest of it, you know you'll have an easier life with a phone that runs stock Android, there's no point in choosing something customized (read: more complicated), with risk of locked bootloaders and whatnots.
And you're right: you can get the puzzle pieces from the Market (or elsewhere) to create a Sense-like experience. That's because Sense offers so many good things in one package that ppl are aiming at re-creating it, but ask this: if you want to re-create it, why not spare yourself the hassle and use the real thing right out of the box?
As for the clock: I haven't even owned, much less worn a watch for at least about ten years, nor do I feel the need. Actually they seem pretty redundant now that mobiles have become as complex as they are and being carried everywhere. But as for the battery percentage - I couldn't agree more, I wish I knew why HTC itself doesn't make it available at least as an option.

In addition to the great points made by breathlesstao, I'll add the following:
Many devs concentrate on performance, stability and removing bloat when developing their ROMs, so if you want UI mods like battery percentage etc then the option is there for you to do it yourself. It would be nice if HTC could add percentage but they do have a battery widget that shows it.
As for on screen icons, I suppose many people like a sleek looking interace with not a lot of clutter. Plus, the more you have on the homescreens the more likely you are to experience lag when scrolling between the screens. Personally I have every app I use often on one of the 7 screens and if I need anything else it's only a few presses away in the all apps menu. I like it to be set up with each page having similar types of app, so on one I have music / media related stuff, another tools / settings type stuff... etc. See my helicopter view screenshot below for an example. My screen aren't crammed, but then they're not too sparse either.
I actually like the flipclock as it integrates local weather and just generally looks cool... I also haven't had a watch since the 1990s.
Choice and the ability to customise things are part of the many joys of Android, you set it up your way and use it your way.

The replies are right in. As for the launcher I have people coming to me all the time cause their phone is slow and lagging and whenbi unlock screen they have dozens of shortcuts all over the screen. Of course its gonna be slow when it need to reload a the launcher and all those Widgets. I swear some look so much like an icrap with all the shorcuts when I see it I have to double check. Lmao
As for the battery icon, you have to edit the coding for the file to add the extra 150 images that make up the % battery and charging icons and the bigger the file......
Now the clock well to be honest I remove the clock from the top bar any chance I get as I see it as pointless. We have Widgets for that.
As for sense it has its pluses like everything is prebuilt in. Social networking (not sure as I don't use FB at all) built into contacts and all the other handy apps that it comes with. I mostly run a senseless Tom my self but that is only due to it be long a resource hog. But the contacts and dialer work so well together that I have not found a better dialer/contact combo. The sense 3 lockscreen is just too good. I have widget locker but prefer the sense lock screen

Some very good replies, and here is my take, i've been modding my phone(s) now for a few years now (Since the Windows Mobile 5 Genre) and I would say function is not the only thing i look for. I want "coolness", "graphics"... I love the way the flip happens when you unlock a Sense ROM ..I strive to make it smoother !
Having said that I do resort to simplicity at times however, and you can too. have a look at Cyanogenmod and get Launcher Pro.. Ain't nothing simpler than that with the most "Function".
The ROM above will satisfy anyone who loves Function over Heavyness and also it has the option of showing percentage battery amongst plethora of other customizations neatly laid out in the settings menu.
But sometimes that just isn't enough for me..I want a ROM with More......Sense framework is probably the best Integration of everything I've ever seen. Yes its huge ! But then...this phone ain't that weak either...It is a beast
That is why you have an "option" my friend...an option to choose non-sense ROM or a Sense ROM. You could go for a Sense ROM (if you like all the integration of sense) and get yourself a different launcher from the market if you choose..customize it with the battery percentage mod.... yourself... The Dev's like to leave the option customize some aspects of their ROM's to the users... mostly because its personal preference.
The Sense Rom cooks, mostly, give u the most basic thing... A highly optimized ROM with a stock-like UI. You can choose to customize it the way you like ! After all thats what XDA is all about ..do it youself modding..

Hi all,
Your responses are appreciated and it's nice to have a polite conversation about this!
You're right breathlesstao, what the hell's a hardcore user. I just meant anyone who'd flash a ROM, root their phone, perhaps mod some element themself.
So I guess many of you - suprisingly for me - are happy to swipe between screens to get to their apps or widgets. You like what less clutter for doing this. Can see your point of view! I don't experience any lag though, zelendel, for packing my homescreens.
I suppose it was assumed that if you're more knowledgeable you'd be aware of apps and widgets with more options and functionality than the Sense launcher and its own widgets, and choose to use the former instead.
To be clear, I do like using other HTC features such as their contacts and dialler. It's just the homescreen layout I'm ranting about.
In particular for me, a good GUI, as well as looking pleasant, is as simple and quick to to use as possible. So when, for example, I'm going for a lunchbreak at work it's satisfying to be able to put my music or podcast-player on in a second without having to hunt it down.

i keep meaning to try a non sense rom but i like virtuous unity 2.39 sense 3.0 rom so much i´m loathe to part with it.
i know it only takes twenty minutes to go back to it but i just find it does everything in such a pleasant manner.. its smooth fast responsive and most of all it looks the buisness. plus as others have said you dont have to use all that sense stuff if you dont want to.
for music i do tend to use the stock player but i have been playing with other ones of late same with video but things like the clock and weather widgets for me are much more polished on the sense versions than anything comparible available from the market. plus i´ve not had any problem running low on ram or anything, the dhd is more than capable of handling sense 3.0 and whatever else one cares to throw at it without any hiccups

Circle launcher 1x1 widgets are the best
Sent from my Inspire 4G using xda premium

killersloth, thanks for the heads up - it looks very useful.
ponk2k, you know I also use VU (2.39) but with Launcher Pro - have uninstalled the Sense widgets that aren't connected to anything else. You probably think what's the point! To answer my own question, I wanted a custom ROM for things like battery life optimisation, and the VU team's branding has seemed more user-friendly to me than the non-Sense ROMs. Though maybe I'll try one soon. While I've got you though, can I ask if you have a problem with the brightness dimmng slowly on command in most scenarios with that ROM version? More info in my question here:

Just a fair warning man. No rom will be 100% bug free. That is what the stock roms are for. The roms here are for learning and trying new things. So there will always be bugs that need to be fixed. Plus some things that one person may see something a a bug while another sees it as a feature.

I meant with the basic day to day phone functions and stuff like WiFi, video playback etc. To me that's an expected level of functionality for any non beta ROM. I've flashed and tested many over the last 2.5 years of owning Android handsets so my standards are quite high

I haven't had any problems with vu dimming slowly no. I do find that the dimming settings on the ROM are a bit brighter than on the stock ROM though but with no noticeable battery drain incurred.

Thanks will have to investigate further.

Using Blackout ICS

I'm new to using a rooted device and installing custom ROMS, and I love it!
I've loaded the latest Blackout ICS version 3.0.0, and am really impressed by how well it works. I immediately noticed that battery life is better than anything I've used previously, always different versions of Gingerbread. So that's a big improvement straight away. As others have highlighted, it's a bit laggy at times, but I overclocked the CPU and it runs much more smoothly. Even just 1.2 GHZ produced a noticeable improvement, and I'm now on just under 1.5 GHz, which I gather is a safe setting. I was worried about this affecting battery life, but if it has it's barely noticeable. I suppose it only runs at the fastest speed when it needs to.
The only problem with the ROM is the auto-brightness, which jumps up and down even in fixed light conditions. Not sure if the developers pick these threads up, but that is really the only issue I've found.
As the DHD seems to be the only device not to be getting an official port of ICS, I'd definitely recommend giving this ROM a try.
With all these other devices getting updates, is it likely that more fully working ICS ports for the DHD will be on the horizon?

Really? You get better battery? I suspect i get a little less battery time...

You should also try AOSPX and Nik Project X. The first one is stock ICS and the second one is ICS with Sense 4.0. I tried both of em and they work flawlessly on my DHD.
Haven't tried Blackout yet because I saw in the thread that there were still quite a few issues to be solved.

I like the look of Nik Project X, though the final post on the forum raises an issue with not being able to get HSDPA data speed. I'll keep tabs on that forum and maybe give it a try.

Hmm, haven't really paid attention to that (I 'm mostly on WIFI). I 'll do a speedtest when I get the chance.
Edit: Did a quick test and I 'm getting 3,6Mb down / 1,6Mb up (inside a server room right now so not the best connection). Seems quite normal for my network (7,2Mb is max speed I can get from my provider). Of course the max HSDPA speed is alot higher but that 's something I cannot test.

Hi,
I've just installed, and recovered my apps, as i've wiped battery calibration i cannot talk about it, but OC is excellent. Even in default frequency the desktop turns without any lags, but as you mentionned, sometime there are some lags (typing on keyboard for instance) but i guess it's linked to the OC profile changing , try in performance instead of on demand, this should solve that.
Regarding the brightness i agree , it seems it change on "i don't know which parameter" from bright to low brightness.. so i've installed Bright day app to set the brightness along the day at low value and i've set on the main desktop the brightness widget to up from system parameters to push it up when i need, then bright day will recover the setting after a while..

So after few days of testing here are my feelings :
Takeing account of deamon set to 1,2Ghz, i can still reach 1d and half near 2days without charging , with a light use :
Allways connected to network though HSDPA (as i take train it often check the network to change the connected cell)
Playing 20-30min 3times a days to Pirates of carabean (3D game multiplayer so connecting to the network)
Surfing a bit
no music
no video
With an harder use i reached 1d wake up to sleep:
still same network condition
playing double time at least (1 to 1,5h 3times a days)
Surfing more (1h)
no music an no video
using battery eater apps (windguru) a bit
to resume my feeling on battery is excelent, i've noticed a light improvement on idle battery drop, a bit accelerated over time (due certainly to used app remaining processes.
Let's go now to the issue i've noticed :
-Back tactil button doesn't work on phone screen while it works everywhere else
-Using smoth rosie to supersmooth show a light display trouble when reducing the app drawer windows (doubling the reducing animation)
-Light keyboard trouble doubling the A letter some time (like if the touchscreen has been typed twice when its not the case)
-blackout tweak shortcut from top task bar doesn't linked (need to go through the app drawer to access it)
-Folder creation missing from widget/app shortcut addition screen (or i didn't found it) , i use the moving app on another icon to create it (i don't know if it's the ICS new way of creating folder on desktop)
The plus i've found (don't know if it's an ICS feature) : create a folder in the lower task bar : can jump from 4 shortcut to full app contained in your phone accessible from the locked screen : I loved that !
The overall impression is really great and for an old phone that "doesn't give a good experience of ICS" following HTC, i feel this ROM fullfill my expectation from ICS on my Desire HD !
Many thanks to the Blackout team !

Yes. Some can't send at all. Some have data drop in and out while sending and some have no issues. Seems weird to me since the hardware is supposed to be the same for the most part. I think apn and radio combo has the most to do with it.

Love this ROM...
This ROM would be my daily driver if the Wifi hot-spot worked. Has anyone found a work-around or fix? Wifi Tether didn't work either btw. I know it's WIP by the devs but they said it wasn't a major priority for them (Boooooo lol) Fingers crossed for v3.2

As noticed recently in the official thread, i've also noticed the magical battery jumps, i first guessed it was linked to the battery calibration wipe i've done before to flash the Blackout3.0 rom, but i can sometime still see this trouble also.
It happen even phone is in use but every time inbetween 30 and 5 percent of battery left. it goes down to low then readjust it to an higher value without any reason.
The phenomen come back lately less often, but maybe devs can check this out. I'm running on a SFR Desire HD recognized as an incredible S on the 3.0 rom.

[Q] What is the mDNIe scenario? (Custom ROMs)

Hi, I am still fairly new around here (and to the custom ROM scene) and I have been lurking around for some time. So far, I haven't had the need to ask any questions as they have all been answered in other threads, but here's one that I am curious about; it's one that I have noticed in a few custom ROMs I have tried so far.
[Q]: What is the mDNIe scenario and what does it do?​
It is located under the Advanced portion of the Settings menu. I've ticked a few of them, but it doesn't seem like it does anything.

mDNIe stands for mobile Digital Natural Image engine.
In stock galaxy S2 rom (at least my i9100 international), under Settings ->Display -> Screen mode, it shows a sample image and three preset profiles - Dynamic, Standard, and Movie. These adjust the brightness, sharpness, contrast on different screens/ in apps like camera.
Custom roms can always have custom settings for these display-related parameters of a phone.
I am not android developer, so I cannot tell you how to turn it on, but I think stock rom has mDNIe enabled by default.

I also wondered about this option on CM10.1, but from reading the quote (from another post) above, I conclude that they are just different settings to tune the displaly of the phone. The differences between each scenario are so small that I can't really notice them, so I just leave it on the preset UI mode.

Yeah, I dug little into it myself and read that they were some presets for color management. I was kind of curious if they were working properly on the ROM I am currently running and if it would have any impact on battery life as well, but if it's as minute a change as you say, then it's probably not worth investigating, at least not for the time being.
Thanks for the reply and the info, by the way. I guess it's more for display clarity if anyone were to have problems with the viewing screen. I'd give your post a "Thanks" if I haven't already met my thanking limit of the day already. lol I'll be sure to give you one when I get the chance to.

Can this be related to the Galaxy S4 auto-dimming problem? If I set the background mode to STANDARD instead of AUTO, it will probably not dim?

[Q] Color profiling with CyanogenMod

It's not a secret that AMOLED screens like the one installed in S4 mini have wider color range than IPS what often results in over-saturated images which were prepared for standard sRGB range.
Stock S4 mini ROM has means to change color profiles. So the question is - if this functionality also included/planned to be included in S4 mini's CM and kernel CM uses for this model? Could profiles be anyhow adjusted?

It's on my to-do list.

Really glad to hear it, Arco! Thanks!
Could you please share a bit about mechanism behind that? Is it really some driver/kernel-space functionality or it is being implemented on higher levels?

Haven't really looked at it yet, but I think both kernel and user space changes are needed.

Hi arco68,
I'm also interested in a solution for the over-saturation problem of the amoled of my S4 mini. Before that I'll keep my stock rom that has the profiles included.
In the meanwhile any progress on that?

S4 Mini oversatured display - solution!
Finally I found something that really works: S4minisettings.apk

look for F4k's post
This build is for cm 11 (4.4 kitkat). The only thing is you have to manually put it to system/apps/ folder and then correct the permissions to
rw,r,r (644)
otherwise it doesn't work.
To get really natural colors instead of the oversatured ones you have to set mode to "natural" and temperature to "normal". Sometimes you have to switch the display off and on to get the settings applied.
Great thanks to F4k!

Cool!
Finally i get rid of this unnatural colours,
thanks peter and f4k! :good::good::good:

If you're interested I've developed an App called "ColorModeChanger" to adjust colors and saturation. You cn visit XDA thread at: http://forum.xda-developers.com/showthread.php?t=3154845
