MIUI ROM – one of the most well-known custom ROMs for Android – has made its way to the Samsung Galaxy S3, as promised by the MIUI team who said that we would see the first version get released as a beta on July 6th (today that is). MIUI brings a unique interface with features such as extensive themes support, inbuilt backup and restore, useful functions such as guard mode, and more, and Galaxy S3 can finally try it out on their device.
