This Application will let you disable the Touchwiz DVFS (Dynamic Voltage and Frequency Scaling), and prevent any CPU/GPU table adjusting through the Samsung DVFS helper.

Why? because it seems to cause much troubles than it fixes, check @mattiadj thread for more details.

How to install:
1- Install Xposed Installer (http://dl.xposed.info/latest.apk)
2- Install Xposed Framework through Xposed Installer App
3- Download DVFS Disabler (Link bellow)
4- Enable it on the Xposed Installer modules
5- Reboot your device

Download.

Tested on my GalaxyS4 (I9505) and GalaxyS5 (G900F) running Android Touchwiz Kitkat 4.4.2.

Change-logs:
1.3.0:
- Add a blacklist option when you enable DVFS, this will let you disable DVFS on some of your selected games, heavy apps...

Required permissions:
- Internet for Ads to support my work, you can remove them through the "Remove Ads" menu

Big thanks to @mattiadj for his help with tests and debugging.

Thanks to @rovo89 and @Tungstwenty for their awesome work on Xposed framework.

This looks great thx! I sometimes wondered why weird things would happen during gaming, where a restart was the only fix to fix lag/jutter

@wanam: you also have an option to enable/disable DVFS in Wanam Xposed module. Is this the same thing so I don't need the extra DVFS module? And if yes, do I have to tick or untick that option to disable?

Nop, it's an updated implementation to support both JB and Kitkat.

This is NOT aimed to boost your benchmarks, it should show you your cpu real perfs, Samsung used DVFS to cheat on its GS4 benchmarks, but they used it also to set some cpufreq limitations.

Am I not understanding, I thought all smartphone soc whether Samsung or not have stock kernel that use dvfs to scale cpu (and gpu) frequency up to meet heavy loads and similarly dropped frequency back down when under lower load or after prolonged high load due to thermal throttling.
How does Samsung differ from this ? (I am aware of so called cheating when certain benchmark detected)
