The HDC Galaxy S3 I9300 MTK6588 unit is already listed on Fastcardtech, but its currently not on stock yet. They just have a test unit given by HDC, and they did an advance showcase of it. Just FYI, HDC always does this for their new products and so Fastcardtech is among the first to have their devices.

Back to the topic, let’s take a deeper look at this upcoming HDC Galaxy S3 I9300 MTK6588.


The HDC Galaxy S3 I9300 sports a MTK6588 quad-core CPU, has a 4.8 inches screen with 1280×720 pixels screen resolution (HD), with 8 megapixels camera and runs on Android 4.0.4 with TouchWiz UI integrated as well.


HDC ones again brings us another variation of the Galaxy S3 knock-off. Now this HDC Galaxy S3 I9300 sports a MTK6588 Dual Core CPU that is clocked at 1.4 GHz. Paired with that is a Mali-400MP GPU, pretty much a sudden change on the trends of MediaTek’s GPU trend as it was used to be Imagine’s PowerVR GPUs.

It runs on Android 4.0 ICS out of the box, and for sure is a multi-language supported device. It is totally unlocked and guaranteed to work with any GSM carrier from all over the world. Yes, with 3G/WCDMA support. Device also support dual SIM, looks like no micro-SIM slot here but that’s okay.

This S3 knock-off now has a 4.8-inch, just like the real S3 and unlike the previous 4.7″ screen on the HDC Galaxy S3 Pro. The screen is a multi-touch IPS touchscreen with 1280×720 pixels HD resolution. That’s one of the best number you can have for your smartphone screen, expect HD game and movie renders. Everything about the display is yes, impressive.

Its snapper set is as well a bit up on the edge compared to previous 8.0/0.3MP camera pair. This one has a 8.0 megapixels main camera and 2.0 megapixels secondary snapper to give you better self-portrait shots and video calls.
