[Q][USA][GSM]Any way to turn off "dynamic contrast"?

Hello all,
I've been poking and prodding my new USA GSM Galaxy Nexus all day and I noticed something: the screen seems to have a dynamic contrast function, similar to that of new TVs. I would like to turn this function off, although I don't see anything in the stock ROM to do this.
NOTE: I AM NOT TALKING ABOUT "AUTOMATIC BRIGHTNESS".
I want to see if anyone else can reproduce this or if it's just me.
Turn off "Automatic brightness"
Set your phone to 100% brightness.
Hold your Galaxy Nexus in portrait mode.
Go to this page in your browser on your Galaxy Nexus:
http://www.samsung.com/us/
(make sure to request the desktop site and not the mobile site in your browser of choice)
Scroll down to the bottom of the page and zoom into the black section with all the links. Zoom in as far as you can. If you're using Chrome, the words "Who We Are" should go across the length of your screen.
Scroll your screen so the words "Who We Are" is at the top of the screen and no white background is present at the top of the screen. The lettering should be pure white. Remember where they are.
Slowly scroll the page up by swiping your finger down the screen so that you gradually see more of the white background and less of the black background until the black background completely disappears off the bottom of the screen.
Swipe back up so that the words "Who We Are" are in the same vertical position they were in Step 6.
Repeat steps 6-8 multiple times at a faster rate. As you keep scrolling, watch the brightness of the screen and/or the whiteness of the words "Who We Are". When you first start to see white, the white will be white, but when more white starts to take over the screen, the phone switches to a less-intense white. (I'm assuming to save battery)
Is anyone else experiencing this?

download supercurio's voodoo mod sequel, the displayexpert beta in the voodomods forum. there is an option to turn off the dynamic brightness limiter. works perfectly!

This comes up once in a while, and many people say they see this issue. But I just can't see it! The sgs2 has the option to turn this off, but nexus doesn't.
Is this available in the kernel code to view and tweak,or is it closed?

Are you considering adding this into AOSP and letting Google know, or just tweaking/adding to other custom ROMs? Or just curious?

I'm not really a dev in any sense, but would like to see if this function is in the kernel and not hidden. If its not hidden then I'd imagine someone would have added an on/off option by now. So I'm not the person to handle this. My ability is at most compiling my own kernel with a little code change, at most, unfortunately.

Yeah. There is some kind of brightness limiter like plasmas have it too to meet energy star standards. Its a lot less noticeable on a phone screen and probably helps with power management. It can be a bummer on plasma watching hockey or movies like ice age. I would gather there is a way to tweak it. On plasma, no go.
teach a man to fish, you feed him for life. teach a man to fastboot, and you create competency. and less threads on xda.

Hmmm? I have an LG plasma TV and I can turn off all the dynamic stuff fine. It's in an Advanced menu on my TV.

all plasmas can turn off dynamic whatever. i am referring to what is called auto brightness limiter aka ABL. i know samsung and panasonic utilize it in their plasmas. no way to tweak it. there is something similar with samsung phones with amoled. bright images get toned down because all the white/brightness suck a lot of juice. i don't know if it can be tweaked on phones, but i think it can somehow.

To disable auto brightness limiter at boot:

Third party camera app until HTC tweaks their firmware?

I'm curious what you guys think. I've never used a 3rd party camera app, so I have no idea if they're even worth it.
Discuss . . .

I don't think that is necessary given the tweaks that are producing good results: capping ISO 200, knocking sharpness down - 1.5 and using medium resolution.

ISO Cap

Sorry if this question sounds dumb, but you can either select ISO 200 from the settings screen or from going into manual mode and setting it to 200. Correct me if I'm wrong, but wouldn't this take every photo at exactly ISO 200?
How do you "cap" it meaning to allow the camera to select a lower ISO if necessary, but not to exceed 200? DSLRs will do this by selecting auto ISO with a 200 cap, or 400, 800, etc. Am I missing something or are you referring to simply setting the ISO to 200? I saw no setting of "auto with a cap".

Whilst waiting for the next OTA for my HIMA, I spent $3 for DSLR CAMERA PRO from Play Store, and it is giving +15% over the current state of stock camera though..

I will give that app a try. I've also been using Camera FV-5 and by the way, Flavio, the developer of that app says the next update will add the ability to save to an external SD card.
The XDA settings seem to help using the stock camera app. I guess it remains to be seen how much, if any, HTC can do with this sensor via software updates.

You're right.. even increasing all by 0.5 makes a huge impact..

I notice you have sharpness set to a +0.5. I thought the XDA recommendation was to set sharpness at a -1 or -1.5?

Yes, your picture was fine. I guess I'll just play around with sharpness a little to see what I like best. Thanks for your help.

I like the one Made in Sweden. Keep em coming Did you use the table to keep the phone stable?

And about that cap. Can you create a max 200 iso or not ?

I'm sorry but it's the only relevant thread about this problem.

[Root] [Guide] How to change your Resolution & DPI on AOSP ROMs

* I am not responsible for bricked devices, displays not working, or your phone melting *
Now with that out of the way, hello! Welcome to my first guide-thingy. As it is my first, I apologise if there is a mistake or if I have left something out, but this process is exactly the process I have used.
Recently I've had a few people ask me about changing their phone's resolution and DPI as said in my signature, so I thought I'd write up a guide for people to use! The ROM I've done this on is the BlissPop AOSP ROM but the process should be similar for most if not all other Custom AOSP-Based ROMs. I am UNSURE if this process works on the stock ROM or any stock-based ROMs.
Prerequisites:
- Root access
- Root File Manager & Explorer (Such as Root Browser or ES File Explorer)
* Root Browser: https://tinyurl.com/aytbttu
*ES File Explorer: https://tinyurl.com/cd4u27q
- NOMone Resolution Changer
* https://tinyurl.com/kjg63jn
- OPTIONAL (For Multi-DPI Patch) Latest AROMA (Now known as Open) GApps Package
* http://forum.xda-developers.com/android/software/pa-gapps-continuation-t3098071
Lets get started!
Firstly, the Multi DPI Patch. It's not essential but allows apps to be properly resized to match your custom DPI, and in the latest Google Apps package it has an option when installing to install a multi-DPI patch for people who are using custom resolutions on their phone. Like me, I'm not using 2560x1440 (Stock 1440p resolution) I'm using 1920x1080 (1080p) resolution @ 370 DPI.
Changing your Resolution & DPI
1. Download NoMone Resolution Changer from the Play Store above (It's free) and grant root access
2a. Open a root file manager (Like Root Browser or ES File Explorer (You have to enable root-access for ES) ) and navigate to the /system folder on internal storage. Find your build.prop at the bottom. Now, you're going to want to create a backup of this file before we do anything as it defines how things work on the phone, so create a copy and move it somewhere safe from being wiped (Like an external SD card)
2b. Click on build.prop and open with a root file browser
2c. Find the line under the #ADDITIONAL_BUILD_PROPERTIES section that says ro.sf.lcd_density=xxx and change 560 (default DPI) to something like 430 if you want the font and stuff to stay the same size or 370 to make it smaller and hit save, grant root-save access if required. Then, open the file with another file manager to verify it's saved and changed. Adjust the DPI to something that you like, but be cautious as not all DPIs work properly (I only know of 370 & 430 that have worked for me). This step may vary depending on how your ROM sets out your build.prop.
3. Set your desired resolution in NOMone Resolution Changer (Mine is 1080x1920, remember to do it backwards so 1080x1920 not 1920x1080 otherwise your phone's GUI will be landscape and not portrait, and will go off the screen)
3b. Set your desired DPI to match the DPI you put into your build.prop file and hit apply (Grant root access if requested). The app will apply your settings and change your screen to match the new settings. It will then prompt you if you'd like to keep these settings, hit yes or no. If you hit yes, it will give you an option to change back the settings after a minute so you can see what the phone looks like at that setting.
*This next step only applies if your ROM has an option to manage the DPI setting itself, like BlissPop does, otherwise skip it*
4. After you've applied your custom resolution and DPI, go to Settings (Yes everything will be massive-sized don't worry) -> Display & Lights -> Scroll down to the bottom, hit advanced Display Settings, and change the LCD Density DPI to match the one you set in your build.prop and NOMone app.
5. Hit yes to reboot or reboot your phone if not prompted.
6. You're done! Your phone should reboot and apply your new resolution and DPI changes.
I have attached some screenshots showing off the BlissPop & Facebook UI at 1920x1080 Resolution & 370 DPI, as well as an example change in the NOMone Resolution Changer App. Lowering the Resolution and DPI is beneficial to those who want to squeeze more stuff onto their screen (it enables lots more text on the screen that isn't really big.) As well as gamers (The lower resolution doesn't strain the GPU as hard.)
If you have any issues, just delete the build.prop you edited from the /system folder in TWRP and copy over the original one you backed up and put it in the /system folder.
Known issues caused by this guide:
- Boot animation may stretch when booting.
- Recent app previews will also be larger for some unknown reason, this is a small side effect however.
Hope this helped!

Now ...again...me....you forgot to mention borked gigantic recents and borked bootanimation on boot.....you should add it to issues list...IMHO

oh...even using 1080p bootanimations doesn't solve that issue....i've never looked deeper into it myself....but tried many workaround w/o succes
/LG-G3/d-855/16Gb/Titanium Black/

I've used this application to lower resolution on my G3 to 1080p but found that the small text and other stuff was blurred because it's disproportionate to the amount of pixels, since 720p would be a more accurate number to downscale to on a 1440p screen (1/2).
Do you notice this "fuzziness"? I forget exactly which DPI I set it to when I did go down to 1080p, but the other thing I realized was that the performance gain was marginal. I did not do long-term battery testing with this, though. So the verdict is still out on whether or not there is any gain there.

you might not gain much or if any juice on battery....but...performance boost is noticeable on.my side...I forgot how it feels at 1440p ...and switched to for a moment....oh gosh....why do apps take longer to open?....back to 1080p and it flies again...
Oh...you must have set too low dpi to get blury text...I don't even know how that looks like...and if you'd change it to 720p your dpi would be around 220 or something ......

I had tested both normal applications and some 3d games that sometimes bring down fps and neighter seeemd to be any better, but I will have to test this with Bliss as that was some time ago.

Hmm, you could be on to something. I need to test with your recommended DPI to see if it fixes the blurriness of small text. Thanks!

So I used the recommended settings of 1080p and 370dpi and the blur is minimized but not completely gone. Bearable, though.
I'll be testing out some other performance things and more long-term battery savings. Thanks again for the write-up. Hopefully it will help with people willing to try out different resolutions and DPI's.

Sorry, but this is the kind of thing that cannot be shown on a software level. Screenshots will not work.
The images and text is just not as crisp because since it's not 1:1 with the pixels it will naturally display fuzzy. This is unavoidable but can be lessened by using better ratios (ideally 720p, but that would just be too low) and different DPI settings. If you do not see this yourself then you may lack the eyesight. Again, it's not very noticeable and the positives may very well be more beneficial than having a perfect 1:1 ratio.

You could try going to 1080p @ 430 DPI. This makes the text similarly sized to the default 560 DPI, only on lower resolution. If you did this, the GPU wouldn't have to work as hard, and your text would still be the original size
But yeah it's worth playing around a bit. I haven't noticed any fuzziness at all at 370 DPI, and I do a lot of reading on my phone.

If you lower the resolution on any lcd screen made for a specific resolution it will make things fuzzy. You can even do this on your computer monitor.
Everyone should expect this as it is not 1:1, but I still consider it pretty useful.

And If that was written somewhere...most people will fall under mass hysteria and take it as granted .....that's a fact....i'm enjoing my huge screen like I did before on 1440p ...it makes no difference for me and side by side comparison with my co-worker's G3 which is all Stock except rooted(by my advice)....makes no difference at all....none, 0,....he didn't notice that I changed anything except THE Beautiful Rom and pure raw power against his Stock G3...so...don't complicate to much....

Notification Area

So I just got my Note10+. I came from a S10+ and I'm loving it minus one thing. App notifications seem to stop at the camera and not go to the other side. Moving the clock to the other side helps, but it feels like a huge waste of space.
Does anyone know of a way to utilize both sides? Any help would be appreciated. Thanks!

I never tried as I assumed that was a display limit. Oblnce you fill that space, u think there is a dot right by the camera to indicate more notifications. I will poke around to see olidni can change.

13 on the left? How do you change the dpi?

In settings>developer options> minimum width, there you input the value,
think the max possible is around 611,

Question how to change aspect ratio of phone

hello, i wanted to change my aspect ration to 4:3 to have a stretched resolution like pc on my whole phone
there is a app called easy dpi changer. It changes resolution, the only thing you get black bars (not stretched res).
is there any way to make it stretched instead of black bars?
here are some screenshot how it looks like after resolution is changed.
thanks

If you stretch 4:3 to fill the 20:9 screen you'll end up cutting off part of the display.. so I think it's not an option

It needs root and I'm actually unrooted.
Other apps just works with adb, like P ixels:Resolution+DPI changer, in playstore.

I think it also has more option than the one you mentioned.
