MI UI (for Xiaomi's phones) customization!!

What I like about having a Xiaomi phone is that there's a bunch of customization for your interface.

I got a icon pack that makes all my icons glossy and button like. The theme (which includes other stuff too like wallpaper and stuff, but you can choose what to change before installing anything) is called GlossyGlass2.

You can also find cute themes there. A lot of them are user made, but there are official MIUI ones too.

This is just my observation as someone who owns a Xiaomi. The other android phones that I owned in the past didn't have this level of standard customization without installing third party apps.
