I’ve used MIUI V5 for quite some time now and starting to fall in love with it. It has smooth and cool interface, It also have tons of themes to choose from. My Xiaomi MI2S were already pre-installed with MIUI out of the box, the GUI has similarity to IOS but it is much powerful and customizable than IOS.
I am now waiting for MIUI ROM for HTC One and I hope anytime will come out soon from the porting team of MIUI. Anyway, that’s all!
