[TWEAKS] List of build.prop tweaks (can be applied to stock ROM)

---

I'll share with you the /system/build.prop tweaks I have in the upcoming Nova.

You can do this on any ROM, even on stock, you just need a file manager with root access and built-in editor. Edit this file and add/change/remove values as follows.

Here we go:

# Force launcher into memory
ro.HOME_APP_ADJ=1

# Raise JPG quality to 100%
ro.media.enc.jpeg.quality=100

# VM Heapsize; 512MB RAM = 48 is better
dalvik.vm.heapsize=48m

# Render UI with GPU
debug.sf.hw=1

# Decrease dialing out delay
ro.telephony.call_ring.delay=0

# Helps scrolling responsiveness
windowsmgr.max_events_per_sec=150

# Save battery
wifi.supplicant_scan_interval=180
pm.sleep_mode=1
ro.ril.disable.power.collapse=0

# Disable debugging notify icon on statusbar
persist.adb.notify=0

# Increase overall touch responsiveness
debug.performance.tuning=1
video.accelerate.hw=1

# Photo and video recording quality tweak
ro.media.dec.jpeg.memcap=8000000
ro.media.enc.hprof.vid.bps=8000000

# Signal tweaks
ro.ril.hsxpa=2
ro.ril.gprsclass=10 
ro.ril.hep=1
ro.ril.enable.dtm=1
ro.ril.hsdpa.category=10
ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
ro.ril.htcmaskw1.bitmask=4294967295
ro.ril.htcmaskw1=14449
ro.ril.hsupa.category=5

# Net tweaks
net.tcp.buffersize.default=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.wifi=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.umts=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.gprs=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.edge=4096,87380,256960,4096,16384,256960

# Disable blackscreen issue after a call
ro.lge.proximity.delay=25
mot.proximity.delay=25

# Fix some application issues
ro.kernel.android.checkjni=0

# Phone will not wake up from hitting the volume rocker
ro.config.hwfeature_wakeupkey=0

# Force button lights on when screen is on
ro.mot.buttonlight.timeout=0

# Disable boot animation for faster boot
debug.sf.nobootanimation=1

# Miscellaneous flags
ro.config.hw_menu_unlockscreen=false
persist.sys.use_dithering=0
persist.sys.purgeable_assets=1
dalvik.vm.dexopt-flags=m=y
ro.mot.eri.losalert.delay=1000

# LG flags
persist.service.pcsync.enable=0
persist.service.lgospd.enable=0

Adding some more (14/08/11) for Nova v4...

# Change ROM name
# (forgot to add this one before)
ro.build.lge.version.release=My ROM name

# Disable LG ****
# (flex must be enabled or phone app will FC) - needs moar testing!
user.feature.flex=true
user.feature.lgdrm=false
user.feature.lgresource=false
user.feature.lgpoweroff=false
user.feature.ls_event=false
user.feature.ls_normal=false
user.feature.sui=false

If anyone has some other tweaks or better values (tested of course) please do share.

Thanks! I go to try with the Orange stock rom v10b.

Nice Noejn.

# Helps scrolling responsiveness
windowsmgr.max_events_per_sec=150

Here I use 260 and it is very smooth and responsive. The maximum value for this tweak is 300.

# Save battery
wifi.supplicant_scan_interval=180

180 is the scan interval in seconds so you can use a lower or higher value.

Good topic

[QUOTE=Noejn;16487272]

# Raise JPG quality to 100%
ro.media.enc.jpeg.quality=100

This will make for very large files. I would suggest using a value of 90-95, this will be indistinguishable from quality 100 while leaving smaller files. You can test this yourself by encoding any high quality image using various JPEG quality settings with the image tool of your choice.

# Net tweaks
net.tcp.buffersize.default=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.wifi=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.umts=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.gprs=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.edge=4096,87380,256960,4096,16384,256960

I don't know what those values used to be in their default state, but I am sure that it isn't sensible to use the same values for all networks. TCP buffer sizes should consider bandwidth and delay of the connection, which are both vastly different between edge and wifi for example.

Other values which seem interesting are:

user.feature.lgdrm=false # disable lg drm service

I can confirm this will disable the lg drm service - I have no idea what it does, but apparently I don't need it.

user.feature.flex # don't disable this

flex must be enabled, else com.android.phone and com.android.mms will crash constantly.

These can be disabled without visibly breaking something:

user.feature.lgresource
user.feature.lgpoweroff
user.feature.ls_event
user.feature.ls_normal
user.feature.sui

Anyone know what they do?

launcher into memory
ro.HOME_APP_ADJ=1

can also be used using another launcher, like Launcher7 or Zeam? Have i change something?

Of course =) It will do the same for every launcher. It isn't specific for LG.

I really don't get it... If this value actually given a better performance, why didn't those LG's engineer use this value for stock ROM?
They do know aren't they?

Ask them, they come to this forum.

don't tell me they come here to learn how to make a better ROM...

Maybe the factory setting is for failsafe defaults. Like ones on computer BIOS, only advanced user dare to change to their own setting.
