dark_knight35 · Jun 7, 2012

Hello everybody,

this is a collection of build.prop modifications.
The red marked ones aren't tested by myself, the others will work for sure.
Please let us know if a red marked works for you.

1st POST MODIFICATIONS
2nd POST HOWTO APPLY

1. ro.HOME_APP_ADJ=1

Locks launcher in memory. Only use with light launchers. This won’t work on ICS and above.

2. profiler.force_disable_err_rpt=1

Only for HTC firmwares. Disables sending of error reports.

3. wifi.supplicant_scan_interval=30

Sets the interval for scanning for WiFi networks in seconds when not already connected to one.

4. ro.ril.hep=0
ro.ril.hsxpa=2
ro.ril.gprsclass=12
ro.ril.enable.dtm=1
ro.ril.hsdpa.category=8
ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
ro.ril.htcmaskw1.bitmask=4294967295
ro.ril.htcmaskw1=14449
ro.ril.hsupa.category=6

3G tweaks.

5. ro.telephony.call_ring.delay=0

Phone rings immediately. You can set a higher value for a delay in seconds.

6. persist.cust.tel.eons=1

EONS stands for enhanced operator name string. Maybe someone knows what that is?

7. dalvik.vm.dexopt-flags=m=y

Enables register map for tracking objects to garbage collect. Might give a little more RAM at the cost of a few CPU cycles.

8. ro.com.google.locationfeatures=0
ro.com.google.networklocation=0

Disables locating. Also delete /system/app/networklocation.apk and /system/framework/com.android.location.provider.jar

9. persist.adb.notify=0

Disable notification while adb is active.

10. ro.sf.lcd.density=240

Change LCD density. Default for Galaxy S is 240. Don´t forget to install patched Play Store after changing it.

11. ro.gsm.2nd_data_retry_config=max/_retries=3, 2000, 2000, 2000

13. persist.service.mount.playsnd=0

14. persist.sys.usb.config=mtp

Enables MTP mode.

15. debug.kill_allocating_task=0

When system has to free up memory, it won't stop the current process(default). Maybe you want to change the value to 1, so it doesn't have to look for an other process to close.

16. net.wlan0.dns1=8.8.8.8
net.wlan0.dns2=8.8.4.4
net.pdp0.dns1=8.8.8.8
net.pdp0.dns2=8.8.4.4
net.ppp0.dns1=8.8.8.8
net.ppp0.dns2=8.8.4.4
net.eth0.dns1=8.8.8.8

net.gprs.dns1=8.8.8.8
net.gprs.dns2=8.8.4.4

HOWTO

It´s saver to edit the build.prop on the computer, as the lines are shorter on the phone. So that`s how to do it:

1. With a root explorer(I prefer ES file explorer), copy /system/build.prop to the root of the internal sdcard (/mnt/sdcard).
2. Connect phone to computer and copy the file on your computer.
3. With Notepad++, open build.prop and edit it. Be careful as some of the parameters already exist. Just change their values.
4. Save and copy the file back to your phone's root.
5. Overwrite /system/build.prop with the edited file.
6. Make sure that the permissions are still rw-r--r--:

7. Reboot into recovery and wipe cache and dalvik cache.
8. New values should be applied now.
9. Enjoy

Thanks for this tips mate..but bit noobish..can ..u do a video for us..please?

Cheers

dark_knight35 · Jun 7, 2012

No, sorry, won't do a video. Which step isn't clear for you? I can edit the howto with some pics.

Yes pic would be nice, Just the scrolling one, also better signal one..thanks mate

rafal408 · Jun 7, 2012

i can't find ro.HOME_APP_ADJ=1 on CM9

I've edited it

. Try with ES file explorer, activate root explorer in it's settings and tick the system thing box.

rafal408 said:

Just put the line at the end of the file. The most tweaks aren't already in build.prop.

dark_knight35 · Jun 7, 2012

I forgot two:

persist.sys.purgeable.assets=1

Allows system to free up more RAM when needed.

debug.sf.nobootanimation=1

Disables bootanimation for faster boot.

These two are for testing, don't know if they work:

ro.mot.hw.HAC=1
ro.telephony.sms_segment_size=160 ->longer SMS? I read of something like that, may doesn't work in all countries.

MAQ7 · Jun 7, 2012

First of all,
Thanks for sharing

Second,
just a suggestion, update the first post and put all of the newly added tweaks there in one place.

Thanks again

Zorigo · Jun 7, 2012

This is great, but the instructions on editting the build.prop are a little unclear, are we copy and pasting the tweaks from the OP into the file, or do we locate the appropriate lines in the build.prop and then change the values to match the tweak.
I'd like to be able to apply better 3g speeds and better signal but it's a little unclear.
Pictures, or thorough instructions would be appreciated.

madushan92 · Jun 7, 2012

no need of a computer, i can do it in the phone itself, can't I?

oswade · Jun 7, 2012

Not sure if half of these make any difference, but I have added a couple to my phone. Some are not applicable to our device for sure.

For the 3g tweaks, my research (google) seems to indicate that for the sgs,
gprs class should be 12
hsdpa category should be 8
hsupa category should be 6

I don't know if these even work though, i can't tell any difference.

One that i do find very useful for ICS, is one that enables MTP (most roms/kernels don't seem to have this option).
persist.sys.usb.config=mtp

Hope that is useful for someone, MTP rocks

Some of the parameters like supplicant.scan.intervall are already there in build.prop. Then you just change the value. If there isn't a parameter in your
build.prop, you can copy&paste it from the OP.

You can do it on the phone, but it's not as save as on the computer. i.e. if you're at the end of a line with a root explorer and press the space bar to get to the next line, you aren't really in the next line and could get bootloop by rebooting. So I wrote how to do it on the computer.

Yes, the tweaks are only slightly noticable, and not all needed. But I'll add MTP to the list tomorrow for sure.

Madflapjack · Jun 7, 2012

This is great. Good job

jelle2503 · Jun 7, 2012

thanks!

there's no point in editing your build.prop if you cannot figure out how to do it after you've read the OP.

next thing they'll ask author of OP to create a custom build.prop for the users that "aren't sure" how to do it.

Just please, learn to use notepad

PS. And if a line doesn't exist in your build.prop, add it!

marwan91 · Jun 7, 2012

first of all thanks ..
i have 2 question:

1. i can apply more than 10 tweaks at once?!
2. do i need space(enter) between every tweak?! or no need?!

1. Why not? That works.
2. Yes, for every parameter a new line.
