[Nokia X] veez21:
Most of these are BS, use if you want placebo. I don't support these anymore.

If you don't want to flash zips that makes your phone faster, or you just want to do it yourself, you should try this.

Intro:

As you know Android is open source and the development of Android is increased in today’s life. Android operating system is having some of the information which is really important . Now, whenever a user wants to do editing in the Android system, they do changes in build prop. Build prop tweaks are something which helps you to do changes in the system and customize your android.

If you are having any rooted Android device, this tweak will work absolutely fine. Every user can do editing. But while editing you have to make sure that you do it properly or else it will lead to a bricked Android device. You can easily increase the bootup time of your Android. Increase sound and much more.

Here are the working build.prop tweaks for our device:
