"Tweaking to the fullest"

Reviewed by / Dec 03, 2013

Semaphore Manager allows you to tweak your Semaphore kernel-based Android ROM [Root]

From CPU to Auto-Brightness, Stratosk's Semaphore Manager allows you to take full control of all Semaphore kernel features. Root required (check developer's description for compatible devices).

Semaphore manage is divided in different tabs (CPU,Tweaks, Modules, SAI and Info). From there you can overclock your device, set governors' min and max frequency, adjust idle and voltages. Likewise, you can set a bunch of stable and experimental features like fast charge, vibrator level, touch wake and auto pickup phone,...

As you can see, all these features require expertise. Don't mess with them if you don't know what you are doing. Use it at your own risk.

Developer's original description available here
