Samsung teamed up with the Linux Foundation and Tizen Association and developed a new platform whose initial name was LiMo, but it was changed to Tizen after Intel joined the project. The launch of this operating system happened in January 2012, but the first Samsung phone which came loaded with v2.3 was the Z1 (it was released in January, this year). This mid-range device wasn’t very well received and only 1 million units were sold in the first month. But Samsung is back with a successor with better specs. Here’s a comparison between the Z3 and the Z1.

Designs and Displays

The fist Tizen-powered phone was a lot thicker (9.7mm), but it was very short (120.4mm) and weighted 112 grams. It looked like any typical mid-range smartphone from Samsung, as it featured a plastic back available in White, Black and Wine Red colors, with curved edges and the sides were protected by a metal frame. Samsung used a 4-inch PLS TFT which supported a resolution of 480×800 pixels and the pixel density was quite low at 233ppi.

The Z3 came with a bigger body and the evolution is noticeable. Besides the three variants of colors (Black, Silver and Gold), the Z3 offers a more interesting design, such as a curvier back on both sides and it’s much slimmer at 7.9mm, while it has a height of 141.6mm and a weight of 137grams. Also, this time was used a Super AMOLED screen with a longer diagonal of 5-inch. The resolution was increased to 720×1280 pixels and the resulted pixel density is 294ppi.


If you haven’t heard of Spreadtrum yet, we’ll tell you that this is a Chinese company that manufacturers chipsets for mobile phones. It’s not very known worldwide, because a few phones are powered by these types of processors, and Samsung a model in 2012, for its Samsung Galaxy Star 2 and Galaxy Star Advance low-end devices.

The Z1 received the model number SC7727S and it had two cores running at 1.2GHz, but they were paired with Mali-400 graphics and only 768 MB RAM. Not much of a big deal, and not to mention that the internal memory had a very low capacity of only 4GB, which supported expansion up to 64GB.

The model number of Z3’s processor hasn’t been specified, but it’s known that it has four cores running at 1.3GHz, which are backed by 1GB of RAM, while the internal memory is double and expandable up to 128GB.

Cameras and Batteries

Samsung placed a mediocre camera of 3.15MP on the back of the Z1, but at least it supported LED flash, while the front camera was VGA. Very disappointing and we expected more from this phone, but for its price of around 77 dollars, the Z1 couldn’t afford to have better specs.

The Z3 costs 130 dollars, but it has an improved rear camera of 8MP, also with LED flash, and the front camera was a big surprise, because it supports a resolution of 5MP.

The first Z1 came with a very small battery of 1500mAh, which lasted 8 hours on paper, when making voice calls. But the advantage is that it can be removed once its lifespan starts to deteriorate. As for the Z3, it received a unit with a capacity of 2600mAh.
