[Galaxy S3 Neo Themes and Apps] Ciro:
HELLO TO ALL GUYS, I MADE THIS GUIDE FOR SHOW TO ALL PEOPLE OR DEVELOPERS OF ROMS ALL THE CODES FOR TWEAKS TO BUILD.PROP ( system ), this work on all devices but some roms can have problems if you put something of this so asking ur Dev roms...​

[TO ALL DEVS: feel free to use all the codes in your rom, but remember give credits to me and xda community for edit codes]​

[TO ALL DEVS: all the codes are working fine in lollipop and are edited by me and others dev for more performance and others thing so not needed do more changes]​
