[Miscellaneous Android Development] H M Judge:
Hi guys !!! this is the second update of my previous thread - build.prop tweaks for all !!!! . i hope this helps you !!!!:cool::D:p

General Performance

debug.sf.hw=1

Edit existing line,

dalvik.vm.heapsize=48m

persist.sys.ui.hw=1

Faster Scrolling

ro.max.fling_velocity=12000

ro.min.fling_velocity=8000

Saves power

ro.ril.disable.power.collapse=1

pm.sleep_mode=1

windowsmgr.max_events_per_sec=60

wifi.supplicant_scan_interval=180

*If you don’t keep Wi-Fi active lowering the value below the default of 90 seems to make Wi-Fi connect faster after being turned on but will consume more power if turning Wi-Fi off has been forgotten when not in range of a known network.

ro.mot.eri.losalert.delay=1000

*Should smooth out disconnects and reconnects, saving battery. Seems to brake tethering with CM7, let me know if anyone else experiences this issue.

Raises quality of images

ro.media.enc.jpeg.quality=90

ro.media.dec.jpeg.memcap=8000000

ro.media.enc.hprof.vid.bps=8000000

Increased Media & Streaming Performance

media.stagefright.enable-player=true

media.stagefright.enable-meta=true

media.stagefright.enable-scan=false

media.stagefright.enable-http=true

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.tcp.buffersize.evdo_b=4096,87380,256960,4096,1 6384,256960

*Note: I don't know why but the forum is placing spaces in the above lines that are not there. The last 3 are for data speeds but have been places here to avoid multiple explanations for the spaces. The spaces are not present when I edit and have even tried retyping them in Word and then pasting the lines in but it still shows the spaces after saving, kind of frustrating. The ends for the above lines should all be the same ending values for each line (=4096,87380,256960,4096,16384,256960). I don’t know why but for whatever reason anytime I save the post the spaces appear.

Disable error checking (Should speed things up a bit)

ro.kernel.android.checkjni=0

ro.kernel.checkjni=0

Disable sending usage data

ro.config.nocheckin=1

To make the phone ring faster when dialing out

ro.telephony.call_ring.delay=0

Disable black screen issue after call (Thanks to Whyzor for finding why looking into the other tweaks)

ro.lge.proximity.delay=25

mot.proximity.delay=25

Disable USB Debugging icon from Status Bar. (Just the Icon, debugging remains enabled.)

persist.adb.notify=0

makes apps load faster and frees more ram. (Edit exsisting line)

dalvik.vm.dexopt-flags=m=v,o=y

Improve 3g data speeds

ro.ril.hsxpa=2

ro.ril.gprsclass=10

ro.ril.hep=1

ro.ril.enable.dtm=1

ro.ril.hsdpa.category=10

ro.ril.enable.a53=1

ro.ril.enable.3g.prefix=1

ro.ril.htcmaskw1.bitmask=4294967295

ro.ril.htcmaskw1=14449

ro.ril.hsupa.category=5

Wipe both Caches in Recovery after adding or changing the above lines.

If you have used the 3g script put out by the developer of theV6 Turbocharger script then they have already been applied to your device.

Next few can be found in the CM7 Performance settings but am including them in case someone would like to use them on another Rom like Miui.

Lock Home Screen into memory

ro.HOME_APP_ADJ=1

Use Jit (Dalvik just-in-time compiler)

dalvik.vm.execution-mode=int:jit

Enable Surface dithering (Improves image quality at the cost of performance)

persist.sys.use_dithering=1

Allow purging of assets (System can free more Ram when needed)

persist.sys.purgeable_assets=1

Disable animation for faster startup

debug.sf.nobootanimation=1

i hope you guys know how to apply these tweaks . if not , you can browse the tutorial in the first update . waiting for your feedback .

regards ,
