[Galaxy Grand 2 Themes and Apps] gracefang:
This is Build.prop just copy/paste what u want of tweaks on ur Build.prop then save & reboot

Guys this may work on ur Rom & may not so some roms didn't work with this build.prop so asking ur Dev roms okay Guys

DEVs this build.prop may helping ur work .. I hope

But make sure to make a nandroid backup before making any changes in the buildprop in case you get a bootloop or softbrick your device and click thanks button if you like my post :D

ALL this tweaks support lollipop LL 5.0 just as normal copy/paste to ur end build.prop on system/build.prop & sure make full backup for ur rom or at least to ur build.prop & make it as flashable zip because if u got bootloop at sammy logo u need to flash ur backup build.prop ... NOTE THIS THAT I HAVENT TESTED ALL AND ONLY FEW 5.0 TWEAKS ON CM 12
