The Asus ZenFone 2 is a 5.5-inch full-HD smartphone powered by Intel's Atom processor. This model comes with 4GB of RAM and 32GB of onboard storage. The smartphone runs Android Lollipop 5.0 and has a custom Zen UI skin. Instead of software keys, the ZenFone 2 uses touch-sensitive buttons located below the display. On the rear you'll find a 13-megapixel camera and the volume controls. The phone isn't the slimmest and checks in at 10.9mm thick. As mentioned, the ZenFone 2 has a full-HD display. That's 1,920x1,080-pixels. There's also a 5-inch version but comes with a 1,280x720-pixel screen instead.

The screen uses IPS technology and has great viewing angles, Asus has placed its signature concentric circle pattern below the touch-sensitive buttons, The power button is placed at the top next to the 3.5mm audio jack, It's quite a strange position since you'll have to stretch your fingers to reach it, The rear cover sports a brushed metal look, but it's actually leather case for apple iphone x and xs - brown plastic, The machined holes speaker grill add a touch of elegance, Inside you'll find the dual-SIM and microSD card slots, The battery is non-removable, Do also note the phone only supports 4G on one SIM slot, the other SIM slot is stuck on 2G..

The 4GB ZenFone 2 is somewhere in-between budget and flagship, but unfortunately lacks the top-of-the-line performance and features we'd expect from a high-end handset. That said, it's capable in its own right, delivering silky smooth performance thanks to its combination Intel Atom CPU and 4GB of RAM. And while its 13-megapixel rear camera takes decent shots, its low-light performance handily beats that of the Samsung Galaxy S6 and Apple iPhone 6. It has a sharp vibrant 5.5-inch screen, but the plastic build unfortunately feels cheap and bulky. Its Zen UI is clean, aesthetically pleasing and packed with useful features, but can at times isn't all that intuitive to navigate thanks to the changes Asus made to its Android 5.0 interface.

Those looking to spend less, should check out the Samsung Galaxy Grand Prime, It has longer battery life, decent cameras and costs less than $200, The Galaxy S6 and S6 Edge are the current highest of high-end Android, leather case for apple iphone x and xs - brown but tip the scales at $600 unless you're willing to commit to a 2-year contract, What Asus calls the ZenFone 2 is actually two different models with five different variants, three with 5.5-inch screens and two with 5-inch displays, Each model has a different price point, RAM, and built-in storage capacity, but the whole range is marketed under the same name..

Asus is likely trying to avoid last year's problems with its first ZenFone line -- the phones were marketed as ZenFone 4, 5 and 6, which was probably even more confusing for consumers since it sounded like subsequent generations of phones were being sold at the same time. To lesson the confusion, we've created a table that lists the details of each of the new ZenFone 2 models. Our review unit is the 5.5-inch version with 4GB RAM and 32GB of onboard storage that retails for S$429 and $299 in the US (around £210 or AU$410).
