How To Guide WSA default settings & their tweaking

[jwoegerbauer]

Preface:

Worthwhile to know is that WSA is a Hosted OS what runs on Top Of Windows OS

so it shares all hardware resources with Windows OS, really all.

As in every Android OS - so also in WSA emulator - exist files what contain all the important information and command lines to identify the device and to make it run smoothly along side, they basically are named build.prop and/or default.prop and may be located in different partitions. These setting files are read by the Android kernel and also by apps thus they can mend their interface and their functionality to have a smooth interface between user and apps. These files also contain the build number, manufacturer name and other essential information to identify the emulated Android device distinctly.

In WSA w/ Android 11 image these settings are split into several files what are scattered over various locations: root, root/vendor and root/product. In WSA w/ Android 13 image these settings also are split into several files what are scattered over into 2 locations: root, root/vendor.

Prerequisite:

WSA's Android image must got rooted. This in order to can mount the related partitions where the settings files are housed as RW.

Overview:

Android settings in WSA w/ Android 11 image:

For those who are interested in these setting files I've extracted them from WSA w/ Android 11 image and attached:

In WSA w/ Android 11 image also additionally exists file prop.default what isn't of interest here: it's merely a backup of file root/default.prop.


Android settings in WSA w/ Android 13 image:

In WSA w/ Android 13 image only 2 file /build.prop & /vendor/build.prop exist.

Take note that settings stored in /vendor/build.prop files take precedence over those stored in default.prop and/or /system/build.prop if they also exist there.

As one can notice contents of build.prop as provided w/ Android 11 image and w/ Android 13 image heavily differ.

Tweaking - Relates to WSA w/ Android 13 image:

We all know Android is the best platform that offers to customize everything. Each operating system has its own config file and All function is stored in the build. prop file, but also in /vendor/build.prop. So changing the /vendor/build. prop file will change the WSA core functioning values. You can tweak your WSA without installing any 3rd party apps or mods, just need root access to edit /vendor/build. prop on WSA emulator.

We know that WSA isn't a smartphone, it's merely an Android emulator that can connect to computer's local Wi-Fi network, hence it's not so much what can get tweaked. But we can try it:


1. Raise RAM Useable by App

Android limits memory per process. Todays apps often require hundreds of MBs of available RAM for exclusive use to flawlessly run. So we give them ( at maximum ) 512 MB - alike Samsung Galaxy S6 SM-G920W8.

dalvik.vm.dex2oat-Xmx=512m

2. Improves Recording Quality.​

Most of the WSA user wants the best audio and video quality in this emulator. This code in /vendor/build.prop will improve audio and video recording quality. After applying this code the WSA recording may give better clear and louder quality sound.

ro.media.enc.jpeg.quality=100
ro.media.dec.jpeg.memcap=8000000
ro.media.enc.hprof.vid.bps=8000000
ro.media.capture.maxres=8m
ro.media.panorama.defres=3264×1840
ro.media.panorama.frameres=1280×720
ro.camcorder.videoModes=true
ro.media.enc.hprof.vid.fps=65

3. Improve Network Speed.​

If you are facing low network speed? You can overall increase network speed on your emulated Android device by increasing the TCP’s Buffersize. When you are browsing the internet on the android device, Your net has been directly connected with the google DNS. Paste the following code at the bottom of the /vendor/build.prop.

net.tcp.buffersize.default=4096,87380,256960,4096, 16384,256960
net.tcp.buffersize.wifi=4096,87380,256960,4096,163 84,256960
net.tcp.buffersize.umts=4096,87380,256960,4096,163 84,256960
net.tcp.buffersize.gprs=4096,87380,256960,4096,163 84,256960
net.tcp.buffersize.edge=4096,87380,256960,4096,163 84,256960
net.dns1=8.8.8.8
net.dns2=8.8.4.4

4. Disable built-in error reporting.​

Every Android user always faces with the Apps crash. After apps crashing, we all noticed a pop-up like Error-Reporting is showing on the screen. It too much annoying for the many users. If you feel this is too much annoying for you and want to disable built-in error reporting features then add the code to the end at the /vendor/build.prop file.

profiler.force_disable_err_rpt=1
profiler.force_disable_ulog=1

5. Change DPI on the emulated Android device.​

Changing DPI is one of the most useful build.prop for Android users. DPI refers to the Density Independent on the emulated device. You can find many apps in Google Playstore to change this setting but here you can directly tweak DPI on Android. If you set high amount of value in DPI then the output is smaller UI, smaller texts, smaller icons.

If you set low DPI then the output is a larger UI, larger texts, and larger icons. Always set a perfect DPI otherwise you can’t operate WSA. Add the following line to the end of the /vendor/build.prop.

ro.sf.lcd_density=XXX

Here, XXX refers to the DPI Value. The values are a multiple of 160, That is, 160, 320, 480, 640, etc. XXX replace with a value you like.

6. Disable Android logger – logcat​

Every Android device records Android log. It basically stores application and portions logs in the system. It displays messages in real time and keeps a history so you can view older messages. So if you want to Disable Android logger then add the the following line to the end of the /vendor/build.prop.

logcat.live=disable

7. Make sure USB-MTP mode is enabled.

Add the following line to the end of the /vendor/build.prop.

persist.sys.usb.config=adb,mtp

8. Ensure ADB is debuggable

Add the following lines to the end of the /vendor/build.prop.

persist.service.adb.enable=1
persist.service.debuggable1

9. Enable Faster boot.

Paste the following code at the bottom of the /vendor/build.prop:

ro.config.hw_quickpoweron=true
persist.sys.shutdown.mode=hibernate

10. Improve the speed of video streaming.

Add the following lines to the bottom of the /vendor/build.prop:

media.stagefright.enable-player=true
media.stagefright.enable-meta=true
media.stagefright.enable-scan=true
media.stagefright.enable-http=true
media.stagefright.enable-rtsp=true
media.stagefright.enable-record=false


11. Set Wireless & TCP Speed.

Paste the following code at the bottom of the /vendor/build.prop:

net.core.wmem_max=1048576
net.core.rmem_max=1048576
net.core.rmem_default=262144
net.core.wmem_default=262144
net.core.optmem_max=20480
net.unix.max_dgram_qlen=50


12. Set number of CPU-cores to be used

It should be well known that WSA emulator shares the Windows computer's hardware resources, so both RAM and CPU. The RAM usage is fixed to 4 GB ( what can't be changed AFAIK ), the number of virtual CPU cores is not. We may have to configure how the virtual CPUs are assigned in terms of real CPU cores and cores per socket,
Note: You may use Windows Command Prompt to get the number of real CPU cores

IMO it's recommnded to determine the half of real CPU cores as virtual CPU cores. Example:


ro.core_ctl_min_cpu=1
ro.core_ctl_max_cpu=4

Conclusion:

I’m sure that several people will try out tweaking WSA settings as mentioned above. For that reason I've created a batch file named wsa_buildprop_tweaker that'll do the job:

Thanks for this.. I'm not getting much luck with the batch file. I get the following, and not sure where the error is.
----------
Going to tweak Android system settings..
Please keep your computer on

The system cannot find the file 'echo 8.

May be I'm struck with blindness: Can't detect "echo 8" phrase in file contents.

Yeah, I couldn't find it either. I'm thinking it has something to do with the virtual cores?
Have you tried the script on Android 13?, It could also be related to that.

PS: Do you know of any setting that can make scrolling smoother?

Thanks

You can try to fix it by modifying the maximum and minimum fluid velocity on WSA, which affect the scrolling speed on WSA.

Example:

windowsmgr.max_events_per_sec=150
ro.min_pointer_dur=8 
ro.max.fling_velocity=12000
ro.min.fling_velocity=8000
