build.prop是Android系統中的一個重要的屬性檔,它記錄了Android系統的一些重要的設置資訊,改變它能夠取得一些意想不到的效果,但是也正是因為.prop的重要性,如果不明白具體的含義的話,絕對不要隨便動它。
今天,我們來看看如何對build.prop檔進行修改,以達成省電和加快上網速度的效果。
注意:修改前請先備份好build.prop檔!
第一步:打開你的R.E,並改成讀/寫模式
第二步:進入system目錄,找到build.prop
第三步:右擊(長按這個檔),會彈出功能表
第四步:找到“以文字編輯器打開”
第五步:加入下面的行列,並最後保存。
第六步:重啟兩次
調整build.prop檔以取得更好的信號和資料傳輸速度:
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
X最大測試到10,超過硬體限制,資料在高速下更穩定? 估計是WCDMA才有用??
(我們的MB860 要用10的哈哈---ro.ril.hsdpa.category="X"
CAT Speeds
Cat 1 = 1.2 Mbit/s
Cat 2 = 1.2 Mbit/s
Cat 3 = 1.8 Mbit/s
Cat 4 = 1.8 Mbit/s
Cat 5 = 3.6 Mbit/s
Cat 6 = 3.6 Mbit/s
Cat 7 = 7.2 Mbit/s
Cat 8 = 7.2 Mbit/s
Cat 9 = 10.1 Mbit/s
Cat 10 = 14.0 Mbit/s
*Note*
You can play with the "ro.ril.hsxpa=2" & "ro.ril.gprsclass=10" values depending on your location. The hsxpa Values range from 0-2 and the gprsclass is either 10,11 or 12. IF YOU GET WORSE SPEEDS..JUST CHANGE THE "GPRSCLASS" TO 12
To save power while phone is asleep
//在手機休眠時更省電
ro.ril.disable.power.collapse=1
To make the phone ring faster when dialing out...
//使電話撥出時更快接通
ro.telephony.call_ring.delay=1000
To make UI more responsive
//使介面反應更快
windowsmgr.max_events_per_sec=150
To save battery by decreasing the amount of time Wifi looks for an access point
//使WIFI在查找接入點時更省電
wifi.supplicant_scan_interval=150
**Now wifi will scan once every 1.5 minutes when not around a known location instead of once every minute which will save battery.**
//現在wifi將每隔1.5分鐘查找一次接入點而不是每分鐘查一次。當你在一個沒有已知接入點的地方。(估計是,如果你開WIFI了,如果沒有連接到接入點,查找接入點的時間間隔改成了一分半鐘)
Change the Dalvik VM heap size
(??? heapsize是棧的大小,是不是影響速度??)
dalvik.vm.heapsize=32m
**If on CM7 then you can just go into CM setting/Proformace to change this.**
To enable the hard key lights to stay on while the screen is on and not timeout
(保持螢幕常亮。。。。汗。。)
ro.mot.buttonlight.timeout=0
**Try disabling BLN if your having trouble getting this to work**
To make the phone come off of the "black screen" in the middle of, or the end of phone calls when you pull the phone away from your face
(在通話中或通話結束時,當電話離開臉時,隔多久??重新亮屏?)
mot.proximity.delay=150
***May kill the dialer***
To disable usb debugging popup
(禁止USB調試提示)
persist.adb.notify=0
**Some devs already have this disabled, or have an app to disable it.**
To give your phone an HD effect fitting a little more on the screen, look for this in you current build.prop and change the 240 to...
(給你的電話一個寬屏感覺??)
ro.sf.lcd_density=X (225 or 230)
。。。。。。這樣修改後,手機可能啟動用時會長一點。。。。。
**Phone will take a little more time booting when changing this value**
To enable Stagefright..Helps stream Video/Music Faster but may not let you watch recorded videos...
(使能stagefrigh,視頻和音樂會更快?但可能不能看你自己錄的視頻了。。)
(Press the enter key after every line typed)
media.stagefright.enable-player=true
media.stagefright.enable-meta=true
media.stagefright.enable-scan=true
media.stagefright.enable-http=true
To enable hardware acceleration where the GPU controls the UI instead of the CPU, giving u a much better UI experience....
(使能硬體加速,用GPU而不是CPU,給你一個更好的體驗)
debug.sf.hw=1
。。。你可能會也可能不會注意到性能上有改變,因為vibrant有一個很好的cpu,哈哈
**You may or may not notice a difference because the Vibrant has a very good processor thats capable of handling the UI very well**
To turn off the bootanimation speeding up the boot time....
debug.sf.nobootanimation=1
To enable the menu button too unlock the phone...
ro.config.hw_menu_unlockscreen=true
To stop the phone from waking up when pressing the volume key...
ro.config.hwfeature_wakeupkey=0
小知識:什麼是build.prop?
/system/build.prop 是一個屬性檔,在Android系統中.prop檔很重要,記錄了系統的設置和改變,類似於/etc中的檔。這個檔是如何生成的呢?
build/tools/buildinfo.sh 腳本就是專門用於生成build.prop檔
build/core/Makefile中使用build/tools/buildinfo.sh 腳本生成build.prop檔,
並把系統預設的system.prop以及定制的system.prop中的設定追加到build.prop檔中
後面還有一些設備相關的配置追加到build.prop
