MWC 2015: 6 things you need to know about the HTC One M9

These are the talking points about HTC's new flagship

Following such a superb phone as the HTC One (M8) was always going to be tricky, and at first glance the M9 might be a disappointment. But look below the surface and there's much to be excited about. 

It's clearly an evolution not a revolution, with a very similar design and no competition-smashing specs. Plus, we've known everything about it for weeks thanks to HTC's unerring ability to leak every little detail ahead of its announcement.

No matter. If it ain't broke, don't fix it, goes the saying. And HTC has left alone those aspects which worked while fixing those which didn't. Here's what's new about it.

1. It has an all-new camera...

Let's start with the big news - after years of maintaining that its low-light gobbling UltraPixel approach was the way forward, HTC's ditched it for a standard sensor this time round.

That means that instead of a 4-UltraPixel sensor round the back, there's a 20-megapixel one. Is that HTC admitting defeat? Probably, seeing as the main criticism of the M8 was that it just couldn't cut it photographically against its rivals.

Rather than just match them, though, HTC may well have outdone the competition here. Samsung's new Galaxy S6 and S6 Edge have 16MP sensors, as does its Note 4.  LG's G3, Motorola's Moto X and Google's Nexus 6 all have 13MP snappers and the Apple iPhone 6 has to do make do with an 8MP effort. Only Sony's Xperia Z3 and Z3 Compact match it.

Of course there's more to (camera) life than megapixels, so the fact that the M9 also gets a fast f2.2 lens (with scratch-proof sapphire cover) is also welcome.

Will it prove to be the best cameraphone around? We'll have to let you know once we've tested it. But at least now it's in the game.

2. ...But it also has an old camera

UltaPixel isn't entirely dead though. HTC's kept it for the M9's front-facing snapper, which should be helpful when it comes to getting flash-free shots in low-light conditions.

Which, given that the front cam is mainly used for selfies, and given that selfies are often taken indoors at parties and the like, is probably wise.

3. It shoots 4K video

Whether this impresses you or not will probably depend on whether a) you've seen quite how good 4K footage is and b) whether you have anything to play it on. Many people will be in the first camp but not the second. But that's hardly HTC's problem.

With 4K TVs getting cheaper all the time - and with 4K content options from the likes of Netflix steadily increasing - 2015 could well be the year in which the super-high-res video format goes mainstream. So it's just as well HTC has made sure its latest phone matches most of the other flagships in supporting it.
