can i use build.prop tweaks on galaxy s III?

i have use biuld.prop tweaks on all my android devices such as samsung infuse,galaxy s II and skyrocket with good affects...
but last time I put this tweak on my galaxy s III
ro.ril.hsxpa=2
ro.ril.gprsclass=12
ro.ril.hep=1
ro.ril.enable.dtm=1
ro.ril.hsdpa.category=14
ro.ril.hsupa.category=6
ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
but my conecction was changing between hsdpa11 and hsdpap15<<< (which i think is the best)...but without the tweak my phone held on hsdpap15...
with the galaxy s3 a can reach 7MB download in my house while the other could not reach that speed but using that tweak i get close between 5MB and 6MB....
i was planning trying different tweaks for scrolling battery life and streaming but im scare of messing with my phone because i bought at full price to use it on my att mvno....
if you have any experiences with tweaks please share with us and let us know which work for you...THANK YOU VERY MUCH
pd:im sorry but my english is not the best!!!

I already test it by myself and this are my result...im on the limits of my town i only get 2 or 3 bars..i made 3 test for each settings
Regular settings
2.93 D 1.05 U
3.23 0.81
2.63 0.69
With internet tweak
5.88 D 0.82 U
6.50 0.95
6.19 1.08
I changed values and got better results this is the tweak try it your self leave a feeback
ro.ril.hsxpa=3

[MOD] Disable CPU Rendering + Build.Prop Tweaks [GB][ICS][JB]

Disable CPU Rendering​I'm not responsible for anything that goes wrong with your device, you know the risks of flashing files to root. Make a backup first.​It's been confirmed that this tweak on Froyo based roms, causes an endless bootloop and doesn't seem to work. Although it's been confirmed to work on Harmonica. So from what I know it will work best on GB and ICS (JB need tests). ​
I've red this article so i want purpose this method for tweak more smoothness from our beloved HD2!
XDA-news
OP words:
"I started this thread over at the LG-VM670 forums at Android Central. I thought maybe it was about time I share it over here on XDA since it's a pretty great tweak and it works without any added issues.
But keep in mind, if your phone doesn't have adreno200 gpu drivers, this won't work and could probably cause an endless bootloop. Now that that's covered, read up and do this carefully, this will not work on every device and is only meant for adreno200. I may have another tweak up my sleeve, but I need a device with something other than adreno200, such as tegra, to test it out on, which I don't have at the moment. Anyway, this worked out quite well for the Optimus V users, I believe it works on Xperia devices as well and it's been confirmed to work on Galaxy SIII. I'll try my very best to keep this thread updated, I don't have a ton of devices to test this on so I'd really appreciate the feedback so I can update the main post and list whatever devices this tweak works with (nobody wants a endless bootloop, so let's inform each other) oh and before I forget.. MAKE A NANDROID BACKUP ALWAYS!! Just in case
I found this tweak while trying to look for a loopy smothness tweak made for ICS, but I ended up finding something better than loopy smoothness, a guide to disable CPU rendering. With this tweak you can take full advantage of your device's GPU. In other words you disable software rendering and enable hardware rendering instead"
Original thread
(related to) http://forum.xda-developers.com/showthread.php?t=1575984​
Confirmed working on:
- BobZhome CM9 [VM670]
- quattrimus CM9 [VM670]
- mrg666 MiRaGe IHO [VM670]
- BobZhome IHO [VM670]
- Galaxy SIII
- Xperia devices
- Tegra Device
- any device with working adreno200 drivers (in this case my LG myTouch 4G is a good example, it worked marvelously and more noticeably on this device)
HOW TO
(thanks for the summary to thierry_hd2)
1) MAKE A NAND BACKUP OF YOUR ROM. Just in case something would go wrong
2) To disable CPU rendering the ONLY things to do are:
- with a file manager with root access go to system/lib/eg
- open the file egl.cfg. DELETE everything inside the file but keep this line: 0 1 adreno200
- rename libGLES_android.so from egl folder. Don't delete it so if there is an issue with your ROM you can revert back to this file.
- REBOOT
That's all you have to to to disable CPU rendering. Depending on the ROM you are using you'll see some improvements or not (compile the poll on the top of the page)
TEST (for return back) Flashable .zip with original ROM files (not tested yet - for who have black screen, try it before recovery) TEST
(Thanks to blacksn)
http://forum.xda-developers.com/attachment.php?attachmentid=1331025&d=1347811207
MY IMPRESSIONS:
I'm trying it now on Tytung V2.7 and seems to works very well.!! :good: this trick can show the limit of benchmarking system (they will give you low score respect the new general smoothness).
Some feedback comes from some users that saw how with this hack, they can now play with GTAIII or other games more fluently.
In addiction to this explanation, disabling CPU rendering reduce battery juice!
Set the permission to rw-r--r-- for the egl.cfg file.
What might you benefit from? So far this is what I noticed.
- performance boost
- speed boost
- increased responsiveness
- better audio quality
- apps such as Facebook that would become slow and unresponsive are suddenly blazing fast

Some universal Build.Prop Tweaks​
If you want, you can apply some extra tweaks. These tweaks will help your HD2 feel even smoother and should improve battery life. Again depending on the level of optimisation of your ROM, you'll experience or not improvements.
- Just to be sure I could go back to the original build.prop; for first made a backup of it!!!
- Then I just opened the build.prop file (in the system folder) and made all the modifications manually. Some of the tweaks where already included, other tweaks had different values!
We need help to test & describe the strings. I'm convinced that using some of them, we can reach new level of optimization.
Thinks You need to know is:
1. All options starting with ro.ril is applied only once during boot
2. Most of other options can be applied after phone booted using "adb shell" or terminal direcly on phone with command "setprop option"
3. All prop settings can be read with command "getprop" and can be redirected to file with command "getprop >> /mnt/sdcard/file.txt"
4. Better/easy way is to rename file and not delete while testing. In case You renamed file and go wrong always can put phone in recovery, mount system, connect phone to pc and restore/rename affected file. This will save you a lot of time and nerves.
(http://forum.xda-developers.com/showpost.php?p=31690267&postcount=89)
After some tests i reached new scores on our known benchs:
Antutu: 3180 (1155Mhz Smartass V2)
Quadrant: 1215 (1155Mhz Smartass V2)
Vellamo: 966 (near Galaxy Note and Galaxy Nexus)
Open build.prop (using Build Prop Editor from market) and modify or add the following strings (if they are not just included). All these settings/tweaks are rom and Android version independent.
dalvik.vm.dexopt-flags m=y
CHANGE TO
dalvik.vm.dexopt-flags m=y,o=v,u=y
then Save & Reboot
In this mode we have set up app optimization for unicore...you set u=n only if you are using a device up to 2 cores.

Using part of tweaked dalvik setting is not recommended, because whole section is result of many calculations and correlations in options. Also it is highly recommended after putting these setting in build.prop to delete cache and dalvik cache and after first boot to make power off and fix permissions in recovery.
Thx to all Devs that will give a hand
Thx to gecata & Pixelfreak for the list.
Thx to all users for feedback

Sounds really interesting, I'm definitely trying it out soon
Could you please correct the links so we don't have to edit them in address bar manually (showthread.php instead of show....php)?

Just correct them! Thx ^_^

Just tried it on my Barebone CM7.
Although the ROM is amazing fast, it seems that this tweak improves the performance.
With original config i had some slight lags in LancherPro. Now no more lags...
Anybody knows a proper way to test if this is working?

I have almost immediate results!
Cheers

Don't want to be a fun spoiler but some things are there for a reason

what's the negative side of this mod?

Its just editing the config file to read only the GPU. You will notice a huge improvement in day to day tasks. However benchmarks will go down. But that just proves how benchmarks don't mean crap after this i'm using my device lagfree! also internet experience is better than before.
Vellamo score: 939 using this trick.
Antutu: 3040 (1075Mhz) 3100 (1155Mhz)
Quadrant Score: 1134

this thing works for now on PARANOIDANDROID HD2 v1.5b ICS 4.0.4

I'm studing for some other build.prop string tweaks..maybe we can reach new performance level :good: i'm looking into all general thread of XDA for find someother things to add. Because surely other people discovered some general tips in other forum's region

Thanks for this, yes, benchmarks drop Down slightly (i have 3103 score at 1190 MHz with this tweak), but, it really improves perfomance. Thank you! \(°_°\)

Can we use the zip file from the original thread to install? And had anybody tried this ok CM7?

It's ok! but if you install it manually you are sure to do everything correct

Sorry I feel like tard but for the life of I can't seem to get the flash able zip.....it said to register android forum and I did but still just says attachment... no file. I know its me, could somebody lend me a hand the kids are making me nuts and I wanna try this before we leave lol
Edit sorry never mind just had to view thread in desktop mode, the zip showed then.

its not an flashable zip. you must do it yourself.

I spent some time for build.prop tweaking. Here is it. The sections are self documented, but if You want I can explain more. All these settings/tweaks are rom and Android version independent.

Info/settings about to edit/tweak the build.prop

I know its not new and i know that many roms+tweaks have it inside,but i think there are many users without any knowledge about this,so ive made this thread,please when anyone knows more than make a post here.!!!
----------------------------------------------------------------------------
how to:
1, Open "Root Explorer" and click the R/W
2, Go to /system/build.prop.
3,backup yout current build.prop.
4, Long-presson Build.Prop and you’ll see a pop up.
5, Text Editor.
6, Type in those few line of words below into the last line of the text then save.
7,reboot and enjoy.

Lets make this thread to learn and discuss about tweak and function of tweak.. Advantage and disadvantage using tweak.. Which part cant running if only use 1 part of tweak.. etc
Its more helpfull than only share tweak without know what are they doing..
Ask permission to original tweak like stagmatis, adrenalin, kuro, etc tweak then discuss in this thread..

does this apply on stock or custom rom? I apologize im a noob

thats the reason why ive posted that other peoples please share her expierence too on this thread.to freaks one idea,lol:good:

Some Modifications you can make on your Build.Prop

I found this from freeyourandroid.com thought i would share it. I would happy If an experienced user has anything to say about it:
The following lines in the build.prop file can be added and edited to change several properties in your device:
debug.sf.hw = 1
Render UI with GPU (relieves pressure on CPU)
dalvik.vm.heapsize = 32m
Set size of Dalvik VM heap (how much RAM each instance of the VM is allowed); depending on how much RAM that is available to a device, this can be increased.
persist.adb.notify = 0
Stop debugging icon from appearing in status bar
windowsmgr.max_events_per_sec = 120
Increase to improve scrolling response
persist.sys.use_dithering = 0
Do not use surface dithering (surface dithering improves image quality)
debug.sf.nobootanimation = 1
Disable boot animation
ro.HOME_APP_ADJ = 1
force home launcher into memory
ro.sf.lcd_density = 240
Set screen density; change according to your device or what suits you, a lower value will display more but may be too small to use on a device with a smaller screen. Also note that changing the pixel density will make some applications in the new market ‘incompatible with your device’.
mot.proximity.delay = 150
Lower to fix black screen after calls issue
ro.telephony.call_ring.delay = 0
Decrease dialling out delay
ro.gsm.2nd_data_retry_config = max/_retries=3, 2000, 2000, 2000
Change MMS APN retry timer from 5s to 2s
wifi.supplicant_scan_interval = 120
ro.ril.disable.power.collapse = 0
pm.sleep_mode = 1
Increase battery saving potential
ro.com.android.dataroaming=true
Enables data-roaming by default in the build
ro.com.android.dateformat=dd-MM-yyyy
Changes default date format to day-month-year
ro.config.alarm_alert=*.ogg
ro.config.ringtone=*.ogg
ro.config.notification_sound=*.ogg
Changes the default sounds for each item. Must correlate to ogg files available in /system/media/audio/
ro.build.display.id=NAMEOFROM
In Settings>About Phone, it lists the name of the build number. This is where you set it.
ro.product.locale.language=en
ro.product.locale.region=GB
Sets the default region and language. You must have the correct letter combo, and the language must be available for this to work.
video.accelerate.hw=1 or 0
Whether to use hardware acceleration to render videos, doesn’t work on all devices
** Mind you, my attempt to change failed, because it said "failed to save". You probably wont have this problem.

Some add-ons
Please always do a backup before you made any changes
And try to do it one by one or at least group by group
So you would know which are working and which are not
And easier to revert changes
Good luck

Many build.prop tweaks set this value to 300, but it seems this is a bad idea. As Google points out, Android maxes out at 60fps. The default value is already allow for a possible max_events_per_sec of 90. Even if you allow for 300 max_events_per_sec, you’ll only ever see 60 of these events in any given second. Therefore, any value much higher than 90 is unlikely to have any noticeable impact on your experience in general. Additionally, setting this value too high can starve other UI events that need to get processed, viz. touch inputs. You’re not likely to feel like your device is running very smoothly when it is busy processing thousands of scroll events instead of responding immediately to you clicking to try and open a link or an app. There may be some specific scenarios where increasing this value does appear to improve system feedback, but changing this value for all UI events across the board will likely cause more problems than it will solve.
