For this week’s Galaxy S2 GT-i9100 ROM of the Week, check out Fusion ROM.
Based on Samsung TouchWiz Android 4.1.2 firmware, Fusion ROM is another custom ROM similar to WizzedKat ROM that brings you S5 features onto your Galaxy S2.
You will find many S5 features including S5 UI, S5 UI sounds, S5 icons, S5 boot animation, S5 AccuWeather widget, S5 toggles, and more.
Fusion ROM also ships with latest S5/Note 3 lockscreen (just like the one on Galaxy S5, you will need to install Galaxy Locker app from Play Store), this is probably the coolest feature since I have not seen the Particle lockscreen on any other ROM yet. Also you get Light/Ripple effects from Galaxy S4.
Other notable features include LCD Density Changer, AC!D sound mod, Galaxy Note 3 keyboard, Galaxy S4 transparent multi-window, Apollo kernel with 50mV under-volting to save you battery life along with Snapdragon BatteryGuru app, which should get you very long battery life.
