Asus is bringing three ZenFone 2 models to Europe, all running Android 5.0 Lollipop out of the box.
First we have the ZenFone 2 ZE551ML, which is the series' flagship, offering features like a 5.5-inch 1080p display, a 64-bit quad-core Intel Atom Z3580 processor clocked at 2.34 GHz, 4 GB of RAM, 5 MP front-facing camera, 13 MP rear camera, and 32 GB of internal memory. For a limited period of time, Asus France will sell the ZenFone 2 ZE551ML for just €299 (its regular price will be €349).
The second ZenFone 2 model, the ZE550ML, also comes with a 5.5-inch screen, but its resolution is of only 720 x 1280 pixels. The ZE550ML further features a quad-core 1.8 GHz Intel Atom Z3560 processor, 2 GB of RAM, and 16 GB of storage space. The handset costs €249.
Finally, the cheapest ZenFone 2 is the ZE500CL, which offers a 5-inch 720p display, a dual-core 1.6 GHz Intel Atom Z2560 processor, 2 MP front-facing camera, 8 MP rear camera, 2 GB of RAM, and 8 GB of internal memory. Asus will sell the ZE500CL for €179.
We assume that Asus will soon launch the ZenFone 2 in other European markets, as well as in North America (where the 5-inch ZE500CL model is already available, though not directly from Asus).
