The build.prop is a system file that stores a lot of information needed by Android to work properly. Some entries can help to fix some issues or speed up the device, but mostly of these so called “tweaks” are nothing but placebo. The thread mentioned below will only prove the point that most of said tweaks are nothing more than myths that need to be busted.

Some tweaks work, but most of them simply do nothing. XDA Forum Member LaraCraft304 did a magnificent job and studied the source code in Android to see which tweaks are rubbish. The results are interesting. Almost 20, yes 20, of tweaks that can be found on XDA do nothing, as they have no entries in the source. Android, after reading the code, simply skips them as they are invalid. Interesting, don't you think?

Of course they are entries that do something, and Laracraft304 presented them with documentation and code examples. This guide only proves that we should not blindly believe in everything and be aware of the placebo effect. The best way is to check the code and verify if a specific entry is worth looking into. Well, that's the end of my short rant, and I hope that no kittens were seriously injured in the process and that you're still awake.

If you are interested in seeing some results, make your way to the original thread and check for yourself. Do you believe in build.prop tweaks and use them? Have you fallen for some of the placebo effects before? Leave a comment below and share your opinion.
