MIUI 4 Android 4.0.3 ICS Custom ROM for Samsung Galaxy Ace

Samsung Galaxy Ace being a low end device is still receiving high end updates. Android 4.0 MIUI 4 based ROM has been released and can now be ported to the device. Before this ROM, MIUI 4 was only available for devices having a high resolution screen, but developers of XDA have made it possible for this low resolution screen to run the firmware on it. As, MIUI 4 ROM is still under development and cannot have so many features as found in the Gingerbread ROM, but still it’s better than the stock ROM. Read on to know more about the installation procedure.
