MIUI  (pronounced ‘Me–You–I’), developed by Xiaomi, is a ROM for Android devices. It is used on all Xiaomi phones and can be flashed into other Android mobile phones. As one of the most successful ROMs, MIUI takes customization on Android devices to a new level with its limitless themes, wallpapers, icons, lockscreens etc.

Today, we heard the news that MIUI has reached the milestone of 10 millions users with supports to over 30 Android handsets after 850 days since it’s first released.

Smile Angel Foundation is a Beijing-based charity supported and managed by the China Red Cross Society. Founded in 2006 by Faye Wong (famous singer/icon in Asia) and Li Yapeng, the foundation helps low-income families with children born with cleft lip and palate (CLP) and also aid in providing general children health care.

As a token of thanks to the users, MIUI team created the MIUILove theme and launched the so-called MIUILove campaign. This theme is free to download, and with every download, MIUI will donate 0.10 RMB to the Smile Angel Foundation.

MIUI is obviously doing a great job, but one of its competitors, Tapas OS which is backed by Innovation Works has been struggling for a while. Rumor says Tapas OS has been acquired by Baidu at the valuation of $10m.
