10 Best Build.Prop Tweaks To Optimize Your Galaxy S II Experience

Samsung Galaxy S II is the hottest dual core Android phone that has gained massive user base since launch. The phone got rooted within hours of initial release and the development community has supported the phone wonderfully since then. In case you have root on your Samsung Galaxy S II and want to tweak your phone without the hassle of testing different ROMs available, then you can also manually tinker with build.prop files to optimize your experience. XDA member, KNZO, has compiled a complete list of Build.Prop tweaks for Android in general and S II in specific.

In order to access you phone’s build.prop, download ES File Manager [Free] or Root Explorer from Market. After the download is complete, launch the app and navigate to /system/build.prop and open the file in a text editor [comes integrated in Root Explorer and ES File Manager].

Once the text file is opened on your phone, type the following commands exactly as they are:
