MIUI 4 ROMs remain popular these days, especially with new supported devices being added to the list. Thanks to the brilliant guys at XDA Developers, users of the Motorola Droid RAZR XT912 and the Motorola RAZR XT910 can now experience Android 4.0.3 Ice Cream Sandwich (ICS) via unofficial MIUI 4 for the said Motorola handsets.

The new unofficial MIUI 4 ROM for the RAZR promises tons of exciting features that are not present in other ICS-based ROMs. For starters, MIUI features a beautiful user interface, extensive customization on themes, and full control of customization with regards to the homescreen and interface.

The ROM is made available for both the GSM and CDMA versions of the RAZR. The ROM is currently in its alpha stage, so it is not yet completely stable for daily use.  Among the current bugs/issues noted by the developer are the following:

  • Camcorder
  • Front-facing Camera
  • External SD card doesn’t mount
  • Data doesn’t come on by itself
  • When downloading anything your phone will warn you about downloading using your data connection
  • Wallpapers don’t scroll
