MIUI 4 for Samsung Galaxy Ace

The Samsung Galaxy Ace can add a trophy to its mantle as it becomes the first MDPI device to get a port of MIUI 4 based on Ice Cream Sandwich Android 4.0.3. Before this, MIUI 4 was available on only phones with high resolution screens, aka HDPI devices. But now Galaxy Ace owners can boast of having MIUI 4 on their HVGA resolution sporting phones as well.

MIUI 4 is still in its early stages, so it doesn’t yet have as many features as MIUI based on Gingerbread, but it’s got all the bases covered when it comes to the beautiful UI. A lot of themes are already available for it, which has always been the best feature of MIUI.

Do note that due to MIUI 4 itself being under development, this Galaxy Ace port also has a few issues at this time which should be fixed as time goes by. Well, we know you’re excited, so let’s get on with the flashing procedure.
