HTC is back with the HTC One M8, its new flagship smartphone for 2014. Here's our in-depth, hands-on review of the new HTC One M8.

HTC's aim was to take the original HTC One, codename M7, and make everything better – an all-round upgrade job. One thing's for sure: there are no major leaps with the M8, but we're seeing a similar trend with all new flagship smartphones this year. The Galaxy S5, for example, adds a couple of new features while the Sony Xperia Z2 is barely different to the Z1.

Let's take a look at the new HTC One M8 in more depth.

HTC One M8 hands-on review: Design and build quality

As you can see, the HTC One M8 looks a lot like the original. However, there are some differences.

Once again, the Taiwanese firm has used a uni-body aluminium design but the metal wraps around to the front rather than having a plastic strip around the edge. The corners of the phone are also more rounded. It has a brushed look and has been treated to gain its glossy finish.

A larger screen (see hardware, below) means that the phone is both taller and wider than its predecessor - predominantly taller - but it doesn't feel too large in the hand. It's also a few grams heavier at 160g compared to 143g, making it one of the weightier flagship smartphones.

HTC puts design first and you can certainly tell that with the M8 in your hand. It feels like a premium smartphone which is something Samsung has failed to achieve, in our opinion, with the Galaxy S5. The new HTC One is ergonomic, but also sturdy.

This is important because, as well as feeling like a device which has been carefully designed and put together, it doesn't feel overly delicate which is a downside to the iPhone 5S and previous metal versions. Visit: New HTC One (m8) 2014 price and where to buy in UK

However, if you do want to protect you precious M8, then HTC has come up with a rather cool flip-style case. It's called the DotView case - for obvious reasons as you can see below. A nice feature is that the time and notifications appear when you double tap on the case when it's shut. You can also use other gestures to perform other tasks such as answering a call.

Viewing the screen through the holes creates a cool LED effect. The DotView case is available in seven different colours.

From launch, the M8 itself is available in three different colours. The most popular is likely to be 'Metal Grey' but there's also 'Artic Silver' and 'Amber Gold' – a line-up reminiscent of the iPhone 5S colour options.

The eagle-eyed will already have noticed that HTC has ditched the dedicated navigation buttons in favour of on-screen alternatives. We'll talk about this in more detail in the software section below.
