In the face of competition from big firms such as Samsung, Sony and HTC, Acer is attempting to carve a space in the smartphone arena with the Acer Liquid S2. Going up against the Samsung Galaxy Note 3 and HTC One Max, we see if this high-end, large-screen handset can gain the firm some traction in the market.
The first thing that will catch your eye about the Liquid S2 is, of course, its size. Even by phablet standards the Liquid S2 is a large phone, measuring 166x86x9mm and weighing 229g. Given its size, the Acer Liquid S2 can be hard to grasp comfortably, and we think that even those with large hands will struggle to use the handset's large 6in screen one-handed.
That said, the Acer Liquid S2 isn't an unattractive device. We got our hands on the metallic red model, which certainly will turn heads on the street and stand out from the throng of black and white smartphones lining store shelves. There are some eye-catching design touches too, such as the circular flash around the rear-facing camera lens.
We found the design rather busy, though, with the Liquid S2 surrounded by ports and holes, none of which are labelled, which makes the device difficult to get to grips with at first. The capacitive keys under the display are different to those you typically find on an Android smartphone, although we soon got familiar with them.
The Acer Liquid S2 has a 6in 1080x1920 in-plane switching (IPS) LCD touchscreen with a pixel density of 368ppi. As you'd expect from its full HD resolution, images and text are exceptionally crisp, and while its pixel density is slightly less than those of the Samsung Galaxy Note 3 and HTC One Max, the Acer Liquid S2's display gives its rivals a run for their money.
We found the screen brightness levels somewhat disappointing, but thanks to the on-board IPS technology the Liquid S2 is well suited to outdoor use and its viewing angles are above average.
