ok, from my android tweaking and modding i know it can be somewhat hard to find everything you might need to make the most of your galaxy nexus so i will put links to them here along with providing support and my own little discoveries here...
This will include everything from guides to different type of tweaks, recommended settings, flashable mods, etc...you name it and it will probably be in here (as i update it)
Any suggestions are highly appreciated and will be added with proper credit
***disclaimer- I am not responsible for any damage you may do to your device, please make sure to have a backup before doing any of these tweaks***
(still a work in progress and expect much much more to come)
Guides/Toolkits

[EASIEST ROOT/UNLOCK TOOLKIT] Wugfresh Galaxy Nexus Root Toolkit v1.4
Build.prop tweaks
To use these just mount /system rw, open build.prop in a text editor, add/modify whichever lines you want, save, reboot recovery, wipe cache and dalvik cache, then reboot
Code:
#incoming ringer delay (already in build.prop) sets how soon (in ms) the phone starts ringing when a call comes in. set between 0 and 3000
ro.telephony.call_ring.delay=
Possible battery saver-
Code:
#disable sending usage data to google
ro.config.nocheckin=1
Code:
#sleep mode for battery savings. 0 power collapse suspend, 1 power collapse (best), 2 apps go to sleep, 3 show clock and wait, 4 wait for interrupt
pm.sleep_mode=
Code:
#change lcd density (already in build.prop), which is like changing the resolution on a windows computer can be anywhere from 240 to 360 (stock 320)
ro.sf.lcd_density=
Performance enhancement, may also help with battery life
Code:
#dalvik cache virtual memory size
dalvik.vm.heapsize= (stock 256m, recommended 320m)
dalvik.vm.heapstartsize= (stock 16m)
dalvik.vm.heapgrowthlimit= (stock 128m)
Can improve overall scrolling fluidity and speed
Code:
# This defines the max event window manager can
# handle in 1 s. We may adjust this # for performance
# reason later
windowsmgr.max_events_per_sec= (recommended 275)
General performance tweak
Code:
#disable the zygote loader
ro.wmt.blcr.enable=0
Extended jni checking is costly in terms of performance and battery life so disabling them is suggested
Code:
#disable extended dalvik jni checking
ro.kernel.android.checkjni=0
dalvik.vm.checkjni=0
Helps with overall performance
Code:
debug.performance.tuning=1
video.accelerate.hw=1
Helps increase picture/video taking quality and video viewing
Code:
#Raise Photo and video quality?
ro.media.enc.jpeg.quality=100
ro.media.dec.jpeg.memcap=8000000
ro.media.enc.hprof.vid.bps=8000000
ro.media.enc.hprof.vid.fps=65
Code:
#help to free up unused ram
persist.sys.purgeable_assets=1
Disables notification of usb debugging
Code:
#stop usb debugging on notification
persist.adb.notify=0
enables/disables (set to 0) dithering
Code:
#Improve screen quality at the cost of performance
persist.sys.use.dithering=1
Code:
#Use dalvik JIT compiler (Just In Time compiler is much faster and should be enabled by default)
dalvik.vm.execution-mode=int:jit
Code:
#disable camera sound?
persist.sys.camera-sound=0
Dalvik vm dexopt tweaks (USE ONE OR THE OTHER, NOT BOTH, i prefer option 2)-
option 1- disable dalvik checking, increases free ram but less optimized dalvik cache
Code:
dalvik.vm.verify-bytecode=false
dalvik.vm.dexopt-flags=v=n,u=n,o=v
option 2- enable more checking for a better performing dalvik cache but may use a little more ram
Code:
dalvik.vm.verify-bytecode=true
dalvik.vm.dexopt-flags=v=f,u=n,o=v
Init.d tweaks
To use mount /system rw, go to /system/etc/init.d create new file, add the lines in, save, and set permissions to rwxr-xr-x
Code:
#disable logcat
rm dev/log/main

Could you add the recommended overall color multiplier values?

Blue 200
Gamma (cannot remember, might be 1.2)
Hi,
Maybe an explanation for each tweaks would be great
X tweaks do this (for battery life or performance) but do this,etc...
The tweaks for the build.prop already exists (there is maybe 3/4 or more threads) in the Android section,some of these have not effect in ICS...
And maybe the general section is more appropriate...?
In any case thanks for this.

most have a simple explanation, the ones that dont are general performance/battery life tweaks
any in particular you dont understand?
I'll be happy to add in more detailed explanations on those

Me,I understand because I've tested most of these and I use Google to understand what they do.But most of the users will ask,for sure...
You suggest some tweaks...I think you could suggest an explanation that comes with.
Not just a compilation of tweaks...
It's just my opinion...

Those are included in the franco app but i guess i can put them in too, maybe morfics battery saver ones too if someone posts them (or i find them somewhere)

I did add some explanations but i still think many explain themselves...unless you're talking about the dalvik dexopt ones...those are somewhat technical

These all look to be only Verizon / cdma versions,why post this in the GSM section?
For Trinity Spiceeeee use these values:
Multipliers:
Red 135(0000)
Green 135(0000)
Blue 200(0000)
Gamma: 0,0,0
Give your brain some time to adjust like Master Morfic says and you'll never wanna go back to stock colors again
Also play around with Gamma/Omap4 control for contrast

I just put the Verizon/cdma versions up first since that's what I have, I'll add in the sprint and GSM versions too if someone can give me a link to them
Just tried some of your tweaks (build.prop) and coloursettings and everything seems to be working fine. Colours look similiar to Trinities, little better imo. While scrolling a bit it feels a little bit faster, but that can just be the result of a placebo though.
Thnx for posting this!
Added custom auto brightness tweaks for custom roms with that option (should help save a lot of battery, actually can go lower than manual brightness)
Hi All!
Kindly share your KCAL settings here
Like this:
Kernel - my kernel - IceMan ( not for public )
OS - LineageOS build myself

Red 216
Green 222
Blue 256
Saturation 65
Value 129
Contrast 129
Hue 0
Thank you!

Red 235
Green 248
Blue 256
Saturation 52
Value 132
Contrast 138
Hue 0
Tianma Panel
Excellent idea to open a thread like this. If anyone has a Kcal profile which makes blacks blacker, whites whiter and colors more vivid, please share your profile. :3. I'm on an LOS based rom by the way.
What app are you using to control the KCal?

Elementalx app its fine, but also required custom kernel for kcal.

Whiter screens
Sent from my HTC 10 using XDA-Developers Legacy app
Hmm, I think I found a profile which I like. I used the DarkDroid profile as the base and changed one value.I only changed saturation.
Red: 250
Blue: 250
Green: 256
Saturation: Default is 45 but I changed it to 65
Value: 120
Contrast: 145
Hue: 0
As different type of panel is available and implemented on our beloved HTC10, shouldn't we share what type of panel too ? it's easily available using DevCheck app
I don't think applying settings from a panel to a different brand is really productive.
It's like calibrating a Sony TV and applying the resulted calibrating profile to a Samsung one, just because models share the same IPS panel ? Hmmmm no !
Btw this topic is an excellent idea !)

You are right; I have updated my post
Hello there, I'm a "true colors" maniac, I have all my pc monitors calibrated with icc profiles and everytime I look at this screen it feels wrong, though is a very good screen
now...I once found some preloaded profiles with elementalx kernel and app, now I wiped and reflashed and they're gone (wat)
anyway, I still haven't found a good one
do you have an objectively good color setting? can share it?
or, if you have any suggestion to make a serious calibration (images, tools and stuff) share it!
thank you for your attention and support!

aaaah srgb is pretty good on balance, but damn washed out.....
5T comes with a few color profiles and last one where you can slide from cool to warn modes.
But the profiles I like the most, have too much saturation on colors.
Are there any option/non-root app to manually fine tune color/contrast/saturation?
If not, there are any root app to do this?
Regards!
Very good question I have the same trouble with profile colours that we can manage in Oxygen OS.

Any kernel that has kcal as a feature can fine tune colour using kernel aduitor
I've got a Spyder5 and measured the OnePlus 7T's display. I'd like to share my settings so that you can have a neutral display colour. Keep in mind that every panel might be slightly different. So as always: YMMV.
Requirement:
- Custom kernel
- Kernel manager that can tweak KCAL
> Instead drag the slider or enter the value mentioned below manually.
- In this case: OOS
Got to Settings > Display > Screen calibration
Select "Advanced" and "AMOLED Wide Gamut"
Set the slider (see the attached screenshot)
(Unfortunately there is no percentage or something similar to adjust it accurately.)
Go to your kernel manager app
Set the RGB to 256, 251, 256 (= lower green to 251)
Done
Additional information:
- On my device I've noticed that it has a green tint no matter what you change in OOS' screen calibration.
- The profile is calibrated towards 6500K. Changing the preferred temperature might yield to slight color shifts but it will be better than not reducing the green tint at all.
- This profile is calibrated towards the 50% screen brightness. Changing the brightness may also slightly change the colours.
- In the end it would be enough for the average user to simply reduce the green pixels to 251 and then set the preferred colour temperature.
what kernel are you using?

Nice thanks.
Does this change the reddish tone of the display?
---------- Post added at 05:58 PM ---------- Previous post was at 05:57 PM ----------
Very poor colour calibration on stock oos. OP7 has better color reproduction
I don't see the attachment to reference.
