READ CAREFULLY before applying...
Procedure:
Need rooted device with root explorer and full permissions.
Located in root/system/build.prop
Edit build.prop and save.
Reboot to take effect.
Note:
Place no spaces between the codes.
Make a backup of your original build.prop if incase stuck at bootanimation you can make a flashable.zip anytime.
Some developers uses these codes in there custom roms if are'nt added then you can add at the end of build.prop so will be easy to recognize.
Many of them may or may not work also it wont harm your device.
If you can help updating me by posting here then i can add/remove more tweaks.
And whatever you do, you will do at your own risk
if you find this helpful, then hit my THANKS meter !!!
if you want to blame me for this, then iam always WELCOME !!!

i hope this is not too hard for me

Valid?
Are these all known to work with our hardware? (I know some entries such as lcd.density will cause problems with certain ROMs)
There is a thread suggesting dalvik.vm.dexopt-flags=v=a,o=v,u=y,m=y (which works well for me), instead of dalvik.vm.dexopt-flags=m=v,o=y
It is like: verify=all dexopt=verified uniprocessor=yes registermaps=yes

also... Spoofing the hardware as a Galaxy Note eh? Interesting! Most places I've seen the hardware spoofed as Crespo.
:good:

mayb it works with diff. roms depending upon the customization of rom owners...i just collected and posted here...so we can test to see which supports or not with our roms and can share with others...most of them are already added in my rom (LH)...as for lcd density 120 is'nt compatible...i will attach an empty flashable zip file for build.prop so that it can b modified with original one if anything goes wrong...i dont think any of those will harm our devices...
Note/Streak=5inch...i knw it sounds stupid but i think we can get more even dual core support'd apps to download :silly:

boot animation does not work
Hi,
I am testing the tweaks for better response/ less lags / speed and call/network quality.
First thing I tried is boot animation disable.
to disable boot animation...
debug.sf.nobootanimation=1
Click to expand...
Click to collapse
The boot animation line I have added n saved.
On restart - the Boot animation still plays.
( ROM - DSC 1.4 )​
EDIT-
Please ignore the above problem-
the "sf" was added in upper case
Another observation -
After boot - the phone shows me lockscreen - in 3 weird and different ways!
and- ends up finally - in a proper manner!

I've been testing a lot of those tweaks for some time for my LXdroid ROM, some of them don't work and some of them are simply...useless
I've included the best of them and more tweaks in my ROM, in version 0.2 though, if i can fix the Skype problem, i will launch it
Many of those tweaks ar for CM7 ROM's, but some of them could work on others
But thanks anyways

DSC already has the tweaks needed, since has been in production stage long now.

@MadHaker,
Thank you very much for these brilliant list of tweaks! Love it... I have seen some are already added in some newer custom ROM developers, but some aren't...
I have some questions...some are silly questions, hope you don't mind answering them. Thank u.
1) Why do we need to disable sending of usage data? Will that cause problem if user is tracking their use, so that user do not go over their data usage quota?
2) What is the benefit of keep launcher in memory?
3) What is the benefit of lock app in memory? Will that make the memory full?
I see the command is "sys.keep_app_1=com.example.app"
What app best to be listed here?
4) If user make phone hibernate instead of shutting down, then is there a way to shutdown the phone? Is it safe to open the back cover and take out the External microSD and/or battery out during hibernate?
5) For key lights to stay on while screen is on...
- Is the a command to make the LEDs to lit at, say 50% capacity, or that is control also by auto-brightness of the phone setting or the CM setting?
6) I don't understand what is and the use of "enable surface dithering". What is it actually.
7) Why is it useful to have "disable usb debugging popup" ?
8) This is neat - "to get rid of "non-compatible device" in market" .
ro.product.model=GT-N7000
ro.product.manufacturer=samsung
- But any side effect of doing so?

BTW...I can't seem to make the hibernate function to work. Didn't see any icon/selection for hibernate. Power button only have Power off selection. Am I missing a step somewhere?
