"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.

    It does what it's supposed to do but it doesn't have a lot of options for heavy tweaking.

    Both the app and the kernel are great, however one minor issue that I have had is that I can't have double tap to wake apply on boot (I may have just overlooked it). If this feature could be added in I would definitely change my rating to 5 stars .

    Semaphore Kernel, in conjunction with it's own app, is epic. My Nexus 4 running 4.4.2 OmniROM, runs buttery smooth, and lag free. I've tried Franco Kernel, Faux123 & Hells Kernel, and this is my personal favourite. The app itself is simple, clean and has
