Summary: The HTC One (M8) ticks most of our boxes: design, build and performance are all excellent, there's no app overload, and HTC Sense is improving with every iteration. Battery life could be better and some of the camera tools may seem unnecessary, but overall it's a winner.

Superb hardware design; Storage expansion via MicroSD slot and USB port; Good gesture-based features; Well-rounded range of apps and UI features

Relatively heavy; Camera features need work; Battery life outside power-saving modes could be better

HTC has a long and proud history in the mobile industry. From their early years as an ODM (original design manufacturer) making phones and mobile devices to be branded as HP and Palm, HTC have grown through leaps and bounds to their current standing as one of the leaders in design and mobile...

Beautiful industrial design; Bright screen and beautiful colours; Fast - both actual performance and perceived

Camera - it's good; but the low resolution lets it down; Bluetooth connectivity seems to be spotty at best; Slippery to hold without a case

HTC made one of the best-designed, probably the best one there is, smartphone in 2013. So they made a lot of great improvements, and a few not so great ones, for this year's release. Check out our full review of the HTC One M8 after the break.

In the past, there's been a set formula for developing a flagship Android phone. Grab all the latest hardware components you can get your hands on, cram them into a body that's somewhat attractive, sprinkle on some customizations over the latest Android treat and call it a day.

Key Features: HTC One (M8) Review HTC has essentially made a rod for its own back with the success of the original HTC One. It won so many awards last year I imagine HTC had to build a new wing at its headquarters in Taiwan to hold them all.

Beautiful design and flawless build quality; Powerful performance aligned with good battery life; Great screen

Duo Camera feels like a gimmick; BlinkFeed and Motion Launch feel unfinished

So, do you want this phone? If you're not a fan of Windows Phone, the HTC One (M8) won't convince you to become one. Window Phone still suffers from the well-documented app gap and you won't be able to get some popular apps such as Instagram, Google Maps, YouTube and others.

All-aluminum body; excellent display; good performance; very good photo software; Windows 8.1 update includes the personal digital assistant Cortana

Low camera resolution; lack of apps for Windows Phone

Pushing the limits- that's what HTC is doing. Many people adjudged HTC One to be the best phone of 2013. And how do you make an exceptional phone even better HTC has the answer and it is called the HTC One M8.

The original HTC One was a huge success, however it perhaps didn't sell quite as well as it should have. Nevertheless, it's a hard act to follow, but the HTC One (M8) improves on it in pretty much every department.

From the moment you pick up the HTC One (M8) it feels like a premium device should, with its aluminium unibody casing featuring a beautiful brushed effect. The increase of display size results in a larger and heavier device that measures 70.6 mm wide and 146.4 mm long.

Fantastic design and solid construction; Intuitive and responsive Sense 6 UI; Strong processing and multitasking capability; Relatively well priced

HTC proprietary keyboard slightly inaccurate; Volume button oddly placed
