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)

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?

Red 180
Green 192
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

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 :D and you'll never wanna go back to stock colors again

Also play around with Gamma/Omap4 control for contrast

Are you sure they're the same? also what about OMAP?

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)
