[Sprint Samsung Galaxy S III] mw86:
*Users with Ktweaker settings reseting: Freezing system tuner and or rom toolbox is a possible fix for either min/max mhz, scheduler or governor resetting in Ktweaker. Another way could be making a backup of your settings, clear data on ktweaker, reboot and restore settings twice as not all apply right first time and reboot again with restore settings immediately at boot.

*Ktweaker Issues if on Kt747 Kernel: could have issues on roms like Freegs3 and it is noted that if you prefer to use Ktweaker to set your settings vs script than make sure no conflicting script is running for example check /system/etc/initd/ for 70tweaks and remove or place somewhere for safe keeping to prevent conflicts with Ktweaker for example min max changing or voltage tables, governor or scheduler. This script in the example is Freezas script to set phone based on screen on and off and current battery level for example of some of its functions, there is nothing wrong with using scripts nor is there a problem with this script in particular. Just be aware there will be conflicts if used in conjunction with Ktweaker and or setcpu and the like.

-#*note#* (you can get away with one of these high threshold tunings and not feel laggy by using touch booster set to 384mhz on booster one and for touch two 486mhz which should help response time on any interactive action where in you touch the screen and immediately resume the normal minimum mhz as during touch boost the cpu still ramps based on load over the touch boost values if and as needed. It provides less frequency steps to target frequency during interactive use)*! 384/486 being conservative and 702mhz touch boost 1 756mhz touch boost 2 for more response and still will not be over target frequency during interactive use.

[Light usage] SIO> ZEN> NOOP> Deadline > BFQ > CFQ [medium/heavy usage]

************

Battery Saving:

-Noop: best battery savings for all mobile but not the best data rates. Considered a simple i/o

-SIO: similar to noop but uses a little more battery with benefit of some deadlines.

-Zen: Combo of noop, sio and deadline.

Balanced:

-BFQ: a good balance of battery and performance.

*tuning for solid state storage

General Tips for faster UI

-enable Hwoverlay and force gpu rendering (leave out Hwoverlay on touchwiz to prevent a noted video playback issue)

-Disable animations and transitions on launcher (or set to as fast as possible)

-Use Launcher options to force launcher into memory like in Nova Launcher (Thanks Pberge)

Create localprop and force app in memory thanks nonato

- Go to terminal type su hit enter

-Type all of the following and hit enter to add an app to local.prop and force it in memory. Nova Launcher would be as follows. If local.prop doesn't exist the command will create it.

echo sys.keep_app_1=com.teslacoilsw.launcher-1 >> /data/local.prop

-(Thanks nonato for posting this trick in Seeder thread.)

Fix Gtalk fully disable if it was removed and causing a wakelock (needs credit need to find poster of this)

Cyanogenmod Based tweaks

-enable memory management options

-disable dithering (dithering on smooths color transitions off can show a banding effect) (if not on a CM based rom the use dithering 0 build prop has same effect)

-16bit transparency (close to half the bandwidth needed for 24/32bit color)

User suggestions for removable apps (Touchwiz)

Stop MPDECISION on a 4.2.1 Rom

- Navigate like in this pic to system/etc

- Open initpostboot.sh

- Go to line 223 (i use droidedit free at play store to edit the file it makes it easy to find line numbers)

- Place cursor in front of mpdecision and insert a #. Save the file and exit and reboot. Thats all thats necessary to prevent stopping mpdecision from starting or showing errors over and over in logcat on Android AOSP 4.2.1.

BUILD PROP

-tested on Freegs3(4.1.1), Goodness(4.1.1)rom, Paranoid Android(4.1.2), Chemistry(4.1.1), Unofficial AOKP(4.2.1), PACman(4.1.2), Cm10.1 nightly(4.2.1), Kiljoy(4.1.1)

- Build prop i use and has been tested on 4.1.1/4.1.2/4.2.1

- Gtojim and I are running these without issues. Tested on freegs3, cm10.1, Paranoid android and PAKman (#*has not been tested with Morphology need feedback*#)

-credit for the build props goes to Rom Toolbox and an XDA member Custodian. Thank you Custodian.

http://db.tt/q7S1s8yp

- Directions same as other build props we have listed. Until we have an easy install script this is for advanced users only who already have experience editing build.prop. I will always suggest using rom toolbox to do so vs manually editing your build prop file. Do not add all of them in without checking if the value exists already. You don't want double lines that one says the line and true and the other false, its hard to say but one may override the other. THIS IS NOT A BUILD PROP IT IS A SIMPLE TEXT FILE WITH ALL THE ONES I USE. THE BUILD PROP ENTRY IS TO THE LEFT OF THE EQUAL SIGN AND THE VALUE USED IS TO THE RIGHT OF THE EQUAL SIGN. YOU MUST SEARCH AND REPLACE OR ADD THEM MANUALLY.

Systctrl settings via Init.d (requires kernel with init.d support or enable initd with RyuInfernos apk link at bottom) (tested on same roms as Build Prop)

- * Thanks Zeppelinrox for talking some settings over with me.

- Help entropy pool

- read_wakeup_threshold to 1366

- write_wakeup_threshold to 128

http://db.tt/NilQsqG6

- Init.d for systctrl with the above set already and other optimized values

- Here guys this one is without anything special for entropy the values related to it are set to default on this one

- read_wakeup_threshold 64

- write_wakeup_threshold 128

- randomize_va_space 2

http://db.tt/rHcNuTfR

- Instructions:

Download. Using a file explorer, i like es file explorer go up from internal storage with a root explorer till you are at / you should see system, sys and much more. Go to /system/etc/initd/ and paste this file in there. Select it and go to properties of the file and select permissions. Change them to rwxrwxrwx. In other words enable read, write and execute for the three options user, system and other or whichever they are called. Now exit and reboot. Now at boot systctrl are applied. These are the presets system tuner sets plus a few tweaks by Freecharlesmanson (if you see him please be sure to give him thanks) and a fix for entropy where noted above.

- What is changed in the two systctrl (initd commands are as follows in the above files except the settings mentioned) (you can pick and choose and make your own initd script):
