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

MMS APN retry timer set to 2 sec( if SMS/MMS couldn`t be sent, it retries after 2 instead of 5 seconds).

12. ro.mot.buttonlight.timeout=0

Key lights stay on while screen is on.

13. persist.service.mount.playsnd=0

Disable notification sound when SD storage gets inserted.

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.eth0.dns2=8.8.4.4
net.gprs.dns1=8.8.8.8
net.gprs.dns2=8.8.4.4


Uses Google's DNS for better internet speed.

17. debug.sf.nobootanimation=1

Disables bootanimation. You can delete the bootanimation (mostly in /system/media) now.

18. ro.config.hw_fast_dormancy=1

Read about this one here: Fast Dormancy in a nutshell

19. ro.ril.enable.amr.wideband=1

AMR Wideband provides improved speech quality compared to Narrowband speech coders

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

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

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

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.

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

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.
