i will keep updating as i play arround with diferent values. if you have any other tweaks you want to add let me know and i will add to the list.
add or edit existing lines to build.prop with text editor. you can do it with rootexplorer or copy it to the sd card and open on your computer using notepad++ or any other text editor and then push it back using abd or root explorer. these should help with performance and battery life.
*MAKE SURE YOU MAKE A NANDROID BACKUP FIRST*
Note: if you dont know what you are doing please dont try. read first and make sure you understand what you are doing and make a backup before doing any mods. i am not responsible for messing up your device but the s3 community and i may assist.

What changes does this make?

it gives you a better benchmark score. i had snapshots but my phone is hard bricked so i cant post them. but i did get to pull the buildprop before it bricked. it gives the phone better performance and makes it run smoother. theres also some tweaks that are supposed to increase data speeds but i was still testing those. then there are some tweaks that save battery and a few that give you better picture and video quality.

@ OP

Please explain what each of these mods do to the system. If you dont know what they do then how will you know whether they work on the S3 and exactly how they will affect the system.

If you dont know exactly what each mod does then please do not use other people as testers until you know how they work and if they are safe.

Op mentioned that he bricked his phone so he is probably in the same situation as you.

This should be closed and content should be deleted from op.

He has not done anything wrong by sharing that.
Ask him for the result of any of the mods rather than giving your crap conclusions and advices.

Few years back, only these types of sharing led to formation of THE XDA!

yea and did you read why i got hard bricked? it had nothing to do with the build.prop. you need to read some more. and no one is forcing you to use the tweaks.:p

i read and understand everything in your thread, it's just a hilarious thread that's all. Mark had a good point ; anything you post in these forums should have an explanation of what they do so that users can understand what they are doing. your thread just has "here, flash this", "oh yea, and btw, my phone is bricked" i know it had nothing to do with what you're are posting, but if you had an explanation of the changes to the build.prop, then you wouldn't have @ssh0les like me give you a hard time about it.
