Tweaks for the Build.prop

[Ciro]

HELLO TO ALL GUYS, I MADE THIS GUIDE FOR SHOW TO ALL PEOPLE OR DEVELOPERS OF ROMS ALL THE CODES FOR TWEAKS TO BUILD.PROP ( system ), this work on all devices but some roms can have problems if you put something of this so asking ur Dev roms...​

[TO ALL DEVS: feel free to use all the codes in your rom, but remember give credits to me and xda community for edit codes]​

[TO ALL DEVS: all the codes are working fine in lollipop and are edited by me and others dev for more performance and others thing so not needed do more changes]​

REMEMBER

Roms like Project Lucky, Noble Rom, and others can already have some of this codes, SO PAY ATTENTION on what you will do or what you are doing because im not responsable of your future problems or errors if you do something wrong so please first of all ask your developers or look in the "BUILD.PROP" if it already have the code you want put​

 

[Zola III]

Ok nice to find them all around on one place all do I don't agree with most of them.
Hire are some for you to try out.

#dalvik
dalvik.vm.heapstartsize=16m
dalvik.vm.heapgrowthlimit=150m
dalvik.vm.heapsize=261m
dalvik.vm.heaptargetutilization=0.75
dalvik.vm.heapminfree=2m
dalvik.vm.heapmaxfree=8m

Adjusted values by my self to fit this tin can based on this as a base:
https://01.org/android-ia/user-guides/android-memory-tuning-android-5.0-and-5.1
I deed go with initial devlik heap size of 16MB instead of 8 as 8 doesn't fit so it's increased almost instantly. I am still testing them my self but I have to say impressions are rather good in many arias from tasks witching to more tasks steady remaining in RAM. Less to none apps crashing & also far less lag in memory hungry apps. All this as this should actually initial save a pretty good amount of ram compared to initial reference settings. The positive effect on battery life remains to be seen but it certainly is positive. I am testing it on last official CM12.1.

You may also want to try:
debug.enabletr=1
It enables Tile based rendering. The tile based rendering is faster but it also needs more time for textures to be loaded so results don't have to be always positive (even in most cases they are). Tile based rendering on the other hand certainly also saves some power.
Even Adrenos aren't top of the pops in Tile based rendering (compared to MALI's & PowerVR where this is default rendering mode) it certainly helps.
Let me demonstrate in tied screanshot.
For rendering composition I use:
debug.composition.type=dyn
This is basically to let it choose by flags between GPU & CPU all do most things are GPU rendered this day's still saving some juice on those that are ment to be rendered on CPU is a good thing. It naturally goes with:
dev.pm.dyn_samplingrate=1

I find this surface flinger config best up to date:
#Surface flinger 1.0 2.0 4000
ro.fling.distance.coef=2.0
ro.fling.duration.coef=3.0
ro.max.fling_velocity=3000

It saves a lot on resources even compared to defaults not to mention over exaggerated other ones & yet it produces very smooth results.

Also remove the remark (#) on:
persist.sys.purgeable_assets=1
It does cost a bit of speed (rather not significant) but I still recommend it to be used in contrast to same page merging where performance hit is significant enough.

That's it in shortly, best regards.

Zola III, Thanks for the tip, i will edit the codes and put more

Hi,
There is a way to increase sound volume in s3 neo? It's way to low! Like editing some file or something... I am rooted but viper app doesn't install it's saying something about the busybox...

Well honey install the busy box comands extension binary.
https://play.google.com/store/apps/details?id=stericson.busybox
(that is installer).
It is possible to manually adjust output levels with good root Explorer & text editor but I don't recommend you to do that as you are obviously a noob.
Anyway the file is located at root /system/etc/mixer_paths.xml
& your interest is only in the:
<!-- Play Scenario -->
Section.

I had to modify something in the build prop file and now viper works but I don't think it increases the in call volume or overall volume. It just gives better headphone audio.
Anyway thanks man! :good:

LOL. When you install ViPER4Android it mods build.prop by it self disabling lo power (DSP) audio decoding. It's natural that it doesn't touch cellular radio layer (fm radio & calls), however all adjustments are in the mentioned omx file.

 

[htb2050]

Thank you very much. I am trying all of these tweaks on my s5 running cm14 ROM and it looks like its running perfectly fine so far. I will test more and see what kind of improvements I get.

Thanks for combining all of these in a single thread. It just removed the need of any kind of performance or tweaking app.

 

[Korax94]

How to apply this tweak? Do I just paste it into build.prop and then reboot? I have cm 12.1

 

[Mantoi]

Thank you for this thread.
