Hello All,
I have looked around different forums hoping to find an app or setting info which allows to modify the screen color, contrast and Gamma . I haven't been able to find any .
I have a Vega Tegra2 replica which has high screen brightness ( faded black colors ) and I am running Vegacomb 8.1 on it.
Can any one please tell me if such an app or modification exists?
Many thanks !!
Anyone has any info?
Sorry, don't know anything that can do it. But it's a nice idea.
It would be very helpful for those that have cheaper tablets/phones and want to improve the screen quality and picture.
Im wondering how come no apps is around? Any limitation on Android OS to handle this or harware limiation?

Thank you so much. This app solve partly my UV and Blue light allergic.
Best.
The link above doesnt work anymore... anynew app that can do this ?
I found it, can actually change colors RGB, saturation, contrast, brightness, invert, make screen black and white with root access

Somsehow work but paid with 4 day trial.
But I actually try to find a type of app that just reduce selected color from screen
Hi!
Is there any way to calibrate Samsung GS2's AMOLED display colours to look like LCD display? I think LCD generates more natural tones than AMOLED. Is there any calibration app or tool to achieve such colours on AMOLED?
I noticed the difference when I transferred phone screenshots to my laptop (which has LCD) and also when I compared the notification shade tones (cyanogenmod 11/AOSP) with nexus 4/5 which have LCDs. S2s AMOLED screen shows browner and warmer shade for QS tiles whereas nexus LCD shows grey colour tiles. This is just one example; many other elements like keyboard, pop ups have this kind of difference.
I am sure there must be some way to calibrate AMOLED screen to look like LCD colours. Has anyone tried this before?
Sammy roms and some aosp/cm roms has this "movie mode" which makes colors alot more natural.
On sammy roms it's under display settings and in aosp/cm etc roms,which has device's "advanced options",it's under screen tab.
As for complete r/g/b,gamma,saturation etc calibration solution as some other phones has in kernels or so,there is no such developed for S2 as far as I know.
And you posted in wrong section,ask mods to move it to Q/A

Thanks to @crachel for moving this thread to the right section.
I forgot to mention that I have tried playing with Advanced display options in settings menu of AOSP ROMS yet those options couldn't do the trick.
There is an option to do this. It's not a calibration, but a way to view your pictures with a correction profile on your smartphone.
I have one of these Spyder4 to calibrate the computer monitor for color reliable work. For this Spyder4 there is an app called SpyderGallery for Android. It's free. Once calibrated, you can view the photos of your gallery color-calibrated through this app...
Hey guys, recently my father got tired of ****ty MIUI and wanted something better for his Mi 5. Since it's not my phone, I cannot test various ROMs and kernels by clean flashing them.
I just need one ROM that I can switch to on his phone from MIUI.
It needs to be 100% stable (he is sick of bugs), needs to have great calling and bluetooth connection, and great battery life.
Please let me know if such ROM exists for Mi 5, and which one is it
(Do you guys face any issues with bluetooth speakers or taking calls via bluetooth in car?)
You can start with jdcteam's aosp. Has been really solid for me.

I've been using LineageOS with 0 problems so far. But it does take some time to set it up that way. For instance, you need to flash the MIUI camera to improve camera performance, and under display calibration adjust the RGB values to 90% to prevent image retention (a problem on MIUI too).
I can confirm that Bluetooth works fine, calling is clear and battery life is good but not better/worse than MIUI. I haven't tried taking calls over a car's Bluetooth.
You should also check out the Xiaomi.eu weekly MIUI 9 builds as they usually fix what Xiaomi broke in their MIUI builds and are actually supported by Xiaomi.

Thank you for the recommendations guys. Are you using the stock kernel or any custom kernel like BB kernel, Nagatobimaru etc?
What is your opinion about AOSPA and RR ?
AOSP Extended all the way. Using it from past 3 months.

Nagatobimaru kernel has terrible battery life for me (like 1h30m SOT even though I was initially excited to try it out because it incorporates EAS). I use LOS stock freq kernel, which removes the underclock of the 32GB Mi5 from 1.8GHz to 2.15GHz but is otherwise just the stock LOS kernel. On this kernel I get between 3-4h30m SOT.
AFAIK LOS is the only ROM with display calibration and all the others have no way to fix the severe image retention which is my main reason for sticking with it. If it doesn't bother you or affect your unit then I can highly recommend AEX which seems to be the ROM 90% of the devs are on.

What do you mean by the image retention issue? And what have you calibrated? As far as I understand, you have just tweaked the RGB values of the screen. Can you tell me your values? I think the same thing can be done via Kernel Adiutor if you are on a kernel that supports KCAL. AFAIK, stock LOS kernel doesn't have it but most ROMs and all custom kernels have it.
What about AOSP by JDC team, it appears very stable with EAS?

Does this problem have anything in common to the top edge of phone bleeding? Isnt that hardware's fault?

Yes, it's the same problem - I am unaware whether this is a software or hardware problem, but you can correct it 100% with software. It looks like lightbleed right around the border of the phone and you can see ghosting of previus apps around the corners (especially on a grey background). It's easy to fix in LineageOS, but I've had trouble in every other ROM I tried so far.

Its not ghosting its more like a radiant, something like a glow that increase and decrase...

It looks light an orange tinted lightbleed right around the borders of the display and some ghosting of previous apps are overlayed on the current app (especially visible on grey backgrounds). Check the attached image to see what mean, and this is only about 50% of how bad it can get if you don't adjust for it.
Yes I just tweaked the RGB values to 90% (anything more and you can still notice the effect).
I tried using Kernel Adiutor to fix this problem to no avail, using different ROM and kernel combinations. I never checked if the kernel supports KCAL specifically though.
It's been too long since I used JDC's ROM, but if I remember correctly it was stable and fast but lacked essential features at the time (music playback controls, lockscreen torch, display calibration settings). Their Oreo ROM is far ahead of Lineage 15 in in terms of stability though, not that it's DD ready.

Woah thanks for sharing this man, I didn't know about this, can you please share the screenshot of the settings you have made?
I have the same issue and I can't decide which ROM to flash. MIUI 8 is too laggy, MIUI 9 is faster but all apps crash randomly. I will unlock my phone tomorrow (after the stupid 72 hours waiting period) and I am hoping that this discussion will help us decide. Most probably it will be a choice between Xiaomi.eu or LOS.

As someone who recently used both Xiaomi.eu and LOS14.1 I might be able to clear that up.
Xiaomi.eu MIUI9 build is almost identical to MIUI 8. There are a few minor tweaks to the UI such as the task switcher which is now more immersive and the new icon pack. Settings are now more bundled together and ROM/System info is graphically displayed. Split screen multitasking seems to be the only new feature. I haven't experienced a single app crash, but the system animation speed was set way to fast by default and transition animations show tearing each time you switch apps. In short, it's fast but not smooth.
I switched back to LOS quite quickly. The only feature MIUI has that LOS doesn't is Dual Apps, and since I don't use that the choice was very simple. LOS is much smoother and faster, with minimal features on top of AOSP. I enjoy the additions, it doesn't feel bloated or barebones.
If you are going to use LOS, I recommend doing the following:
-If you have a 32GB Mi5, flash the LOS stock freq kernel
-Set the display calibration as per my previous posts
-Activate touch home button, always on fingerprint unlock
-Install Magisk
-Flash MIUI camera Magisk module + OISprop-Magisk
-Flash iYTBP Magisk module
-Flash unified hosts Adblock Magisk module (make sure to select systemless hosts in Magisk settings)
-Install Google camera HDR+
-Use Nova (paid) or Lawnchair (free) as the launcher
That should get you going and solve most if not all annoyances coming from MIUI. You'd be amazed with the quality of Google Camera HDR+! Just check the attached samples (they are all compressed due to Xda but you'll get the point).

Wow! that was very informative. Thanks a lot man :good: . And yes, I get the point about the photo samples are amazing.
I have the 32 GB version and I already purchased Nova Launcher and use no matter what. I will have to find the addons you mentioned as I have no idea what they do. It's the first time I install a custom ROM on my MI 5. One final question, do you have any thoughts on AOSP Extended?
@xdadevet
Hi, where is OISprop module ?

I can add all the files you need to a dropbox folder and share the link if that would be easier? I find that the Mi5 is super easy to modify, you shouldn't worry too much. I'll add the firmware you need and GAPPS if that would help you transition.
Yes, AEX is a great ROM with many features. Most Devs seem to be on it (going by their discussions). I haven't found a way to fix my LCD issues on AEX yet, which is the main reason for not using it currently.

You need to run the apk after you flashed the magisk module and rebooted your phone to calibrate the OIS.
As we all Know, Some Tianma Screen Panel has Image Retention Issue, but on Custom ROMs, we adjusted Color Calibration via Either Kernel tweak or inside Display Settings. But with Oreo (8.0 and 8.1) Things have changed. UI turned Whitish Material Color and Display Settings for adjusting Different stuffs too. So Anyone Of u Facing same issue with 8.0/8.1 based ROMs?? I'm on Omni right Now and till now not faced. But What About U all..
Waiting for valuable Response..
TIA..
I installed omnin 8.1 twice in my redmi note 4 and rolled back to LOS 14.1 because just after 15 minutes of usage I got image retention in omni 8.1 .
I also got the same in RR 6 (oreo).

Wait for next Build of Omni. It will have Manual RGB Calibration options. Till then U can keep Night Mode On with minimum Intensity. Or with Franco Kernel, Adjust RGB Value to 240 each.

i had same problem i just change screen panel and set everything on 50% (picture https://www.androidpolice.com/wp-content/uploads/2016/03/nexus2cee_cal.png) everything is fine now
Found Fix
I found the solution.. Just flash havoc rom will fk kernal.. Use smart pixel feature. Set the smart pixel setting to 25 percentage... And in display setting go to colour and set all the value to 95 percentage.. Done ??
In Miui You can change Display temperature From Normal To Warm Or Cool
But when using custom rom like Aex or Lineage i can't find that choice
the screen is really warm and white color is almost yellow
please i need any solution for this i want to make the screen contrast cool Like Miui
Thanks i really appreciate your quick answer
Theres color profile option in livedisplay setting on los based roms, use that.

Use Kernel Auditor app..and if your kernel support kcal you can calibrate the display color profile.
Would You please Explain what is kcal ??????

Its an module for Advanced color control for Qualcomm MDSS 8x10/8x26/8974/8084/8939.. your kernel have to be supported to make fully use of it. check thishttps://forum.xda-developers.com/android/software-hacking/dev-kcal-advanced-color-control-t3032080
The los livedisplay also got manual color calibration option, that should be enough to tinker by your own to get however white you want.

Not really...on livedisplay there are only tweaks for the screen RGB color which is not enough in many situation...in KCAL you have screen value and contrast value and minimum sRGB value those are valuable option to tweak... that's why I've told you...now its up to you.
