Samsung has its moments of glory. The unveiling of Samsung Galaxy S 5 was a big media event, and Sammy is poised to sell millions of their latest Galaxy phones. Some owners of the company’s previous flagship, the Galaxy S 4, had some issues relating to CPU speeds in certain applications. These issues were caused by dynamic voltage and frequency scaling known, otherwise known as DVFS.
If you don’t know what DVFS is for, you may be in for a surprise. Samsung used it to cheat benchmark applications like AnTuTu, and they claimed that they remove it with in KitKat. Naturally DVFS is still there, despite good PR from Samsung headquarters. Disabling DVFS at the kernel level doesn’t solve the problem, as it’s controlled by the ROM. XDA Senior Member mattiadj found a way to disable it and Recognized Developer wanam made an Xposed Framework Module to disable DVFS entirely.
Why is this important? Samsung had the brilliant idea of lowering the CPU frequency after few minutes of intensive usage. Thus after 5-10 minutes of playing an intensive game, your CPU goes down to 304 MHz, which makes the phone barely usable before a reboot resets it. With module made by wanam, rebooting isn’t required and overall performance is improved. Two things are required to use this module though: root and Xposed Framework by Recognized Developer rovo89 and his partner in crime Recognized Contributor Tungstwenty.
If you own a modern Samsung device and are suffering from poor game performance, visit the module thread and give this a try. Please note that while this will likely work for all Samsung devices with KitKat and DVFS, it has only been tested on the S 4 so far._________
