With the Samsung Galaxy S5 hot on its heels, competition is just as fierce for this year's HTC One M8. HTC has added upgraded features and tweaks to its second generation flagship, but looks to be sticking to last year's tried and tested formula rather than delivering an entirely new handset.
The design of the HTC One M8 is similar to that of last year's HTC flagship smartphone, but HTC has made a handful of tweaks and improvements.
The HTC One M8 is built from a single piece of aluminium, which features a slight curve to its rear, meaning that the handset sits in the hand more comfortably than last year's more angular design. HTC has added a slight texture to the aluminium that makes the device easier to grip, as does the handset's 160g weight, which makes it feel robust and durable in hand. It is a little larger than most flagship smartphones on the market, measuring 9.4mm thick.
A downside of the HTC One M8's design, however, is that, unlike the Galaxy S5 and Sony Xperia Z2, it isn't resistant against water or dust, which means that those concerned about their smartphone's well-being might opt for its rivals instead. There is no fingerprint sensor, despite that feature appearing on the iPhone 5S and Samsung Galaxy S5.
Improving on the original HTC One, the HTC One M8 has a larger 5in 1080x1920 resolution HD display with a pixel density of 441ppi. While this makes the pixel density a little lower than that on the original HTC One's 4.7in display, we didn't notice a downgrade in quality, with the screen on the HTC One M8 proving to be one of the most vibrant that we have tested.
Despite the larger screen size, we still found the phone usable with one hand, unlike some devices with larger displays on the market. This, in part, is thanks to the thin bezel surrounding the screen, which means that the handset doesn't feel too unwieldy.
Thanks to the onboard Super LCD3 screen technology, the HTC One M8 also has good viewing angles, with blacks remaining black and colours vibrant. However, we weren't so impressed with the way the HTC One M8 performed in bright sunlight, as we found the display awkward to use outdoors at times. However, this is an issue with most smartphones.
