BlackBerry Passport Review: Don't Believe The Haters

BlackBerry is BACK with one of the most unique and quirky handsets we’ve EVER tested

Rating: 
4.5
Typical Price: 
£529.00
Pros: 
Excellent battery; Best in-class QWERTY keyboard; Gorgeous display; Decent Camera; The ability install and run Android applications via SNAP; BB Hub is awesome for notifications; SD-support; Premium design and finish
Cons: 
BB10 –– even with Amazon Apps –– is still officially app and content-light compared to Android and iOS (Thank god, then, for SNAP); Design of handset won't suit all tastes
Verdict: 
The Passport is a weird looking piece of tech, yes, and the keyboard does take a bit of getting used to, but, like all new ideas, once you’ve accustomed yourself to its ways you feel right at home banging out emails, editing documents and tweeting. Good work, BlackBerry!
Remember when BlackBerry was one of the dominant forces in the mobile industry? It seems like such a long time ago now. Well despite doomsayers prophesising the death of the company for years it has managed to keep going regardless. And just as well too, because BlackBerry's efforts have produced some very interesting and compelling developments; the new BlackBerry OS, and an array of quirky devices which run it. Most bizarre, divisive and ultimately noteworthy amongst these being the BlackBerry Passport.
Possibly one of the oddest looking smartphones in recent history. But as Samsung will tell you of the reaction to its first Galaxy Note device, a skeptical press put off by novelty isn't necessarily a reflection of what the consumer will think. And you really do want to convince the people who vote with their wallets more than anything else.
BlackBerry has now released its first ever Android-powered smartphone. It’s called the BlackBerry PRIV and it is perhaps the most powerful handset BlackBerry has ever produced with specs and hardware that’d get even the most hardcore Android fan’s pulse racing. You’re looking at a gorgeously designed handset, complete with a large QHD panel and awesome 18MP camera. It runs near-stock Android software and ships with a bunch of bespoke BlackBerry applications. Check out our BlackBerry PRIV Review for the low-down on the handset and whether it was worth the wait.
The BlackBerry Passport doesn’t really need any introductions whatsoever –– it’s THAT square phone you’ve been hearing so much about in the run-up to its launch. But is the Passport any good? That depends. KYM has long been a fan of BB10 and what it stands for, but for the longest time we’ve also felt a little let down by the hardware it shipped inside. Can the BlackBerry Passport change this? We aim to find out.

BlackBerry Announces Passport Silver Edition: Up For UK Pre-Order Now

On August 4 2015, BlackBerry announced a new version of its Passport handset; the Passport Silver Edtion. Unsurprisingly, the key difference between the regular black edition and this new one is the silver colour used throughout its design. But this isn't just a colour choice, no, the bodywork is actually made from stainless steel. The spec line-up, however, remains the same as the existing model.
Pre-order details have now emerged for UK fans (it's already out in the US). The phone will be available towards the end of August, but retailer Clove has posted a pre-order price tag of £399.

BlackBerry Passport Review: Design 

If you want to get people talking, give them something interesting to talk about. And in a world of rectangular slabs dominated by two platforms, it’s good to see something a little more eccentric with regards to design. Yes, the iPhone 6 is gorgeous. And, yes, the LG G3 and HTC One M8 are beautifully designed smartphones with excellent operating systems, but variety (at least, outside the mobile space) is considered the spice of life, and for the longest time nothing of note has really happened in the arena of phone design.
They just seem to be getting bigger –– A LOT bigger. Hell, even Apple’s getting in on the act with the iPhone 6 Plus, which is now one of the largest handsets money can buy, save for the newly released Google Nexus 6. Beyond this trend, however, not much else has happened with respect to design; tech brands still worship the thinner, faster, lighter mantra. And that’s fine –– I like svelte, lightweight gizmos. And yet, at the same time, I still often find myself hoping for something truly leftfield from OEMs… it just never happens. 
UNTIL NOW.
The BlackBerry Passport is big –– very BIG –– it’s square AND it has a physical keyboard, which also doubles as a trackpad for scrolling around menus, apps and webpages. And all of that has caused a lot of people to write the handset off as nothing more than a mobile version of a bearded lady, labelling it a freak that’s kind of interesting but hardly convenient in normal, everyday life. But here’s the thing: this sentiment couldn’t be further from the truth. 
Measuring in at 128 x 90.3 x 9.3 mm, the BlackBerry Passport, like all good things, is more than a handful. You can’t really use it comfortably with one hand, but so what? I can’t use my Nexus 5 with one hand all that well. Ditto the iPhone 6 Plus. The Passport weighs in at 196g and is heavier than anything the company has ever produced. It is also more premium than anything BlackBerry has turned out in living memory, with a gorgeous metal frame, high-grade polycarbonate backing, pitch-perfect keyboard, and an ultra-high-resolution 4.5in display.
As I see it there are two talking points regarding the Passport’s design: it’s keyboard and the display. The former is a full QWERTY setup arranged over three rows with the space bar housed centrally on the bottom line of keys. BlackBerry says this is the best keyboard it has ever produced, and it really is –– it surpasses the Q10’s setup in everyway. And the main reason for this is because it is A LOT smarter. On top of that it is more fully integrated with BB10 and the overall experience of using the phone. 
I’ll admit, ahead of using the BlackBerry Passport I had plenty of reservations about this device. The shape didn’t really appeal to me, and the idea of using a QWERTY keyboard, while always an interesting prospect, struck me as a bit antiquated. I really liked the BlackBerry Q10 and used it as my daily driver for a good six months, but in the end I still ended up going back to Android. The Passport is better than the Q10 because it takes the principles that made it great (an excellent QWERTY combined with a decent OS) and evolves it into a handset that feels like a proper, full-on 2014 flagship – something that can and will (in some instances) replace an iPhone or Android handset. 
The design is definitely controversial and it certainly won’t suit all tastes. But that’s OK. If you want an iPhone, chances are you already own one. Ditto for Android. The Passport handles pretty much as you’d expect. It does feel incredibly wide compared to standard-issue handsets from LG, Google, HTC and Apple, and it does take some getting used to… but, AGAIN, so what? You could say the exact same thing about the original Samsung Galaxy Note or the iPhone 6 Plus for that matter.  
Beauty is in the eye of the beholder, which is to say different folks find different things attractive (just look at Benedict Cumberbatch), so rather than taking my word for it –– even though I do like the way it looks, and find Mr Cumberbatch very handsome  –– the best possible route for you, dear reader, is to ask yourself whether you could see yourself using a handset that looks like this? If your the gut answer is no, fine, move along. But if you’re intrigued by its odd proportions and find yourself musing about what it would feel like in your hand, or how its keys work in practice, then I’d advise you to go and check one out in a phone shop because there is a certain je nais sais quois about the Passport that I think A LOT of people will really enjoy. 
Initial sales seemed to indicate this too –– BlackBerry confirmed it sold 200,000 units in the handset’s first two days on sale. The company has remained quiet on exact figures since then, but John Chen recently confirmed the company is experiencing shortages of the handset due to higher-than-expected demand.
Speaking to The Globe and Mail, Chen said: “I’m glad to have inventory issues. It shows that people want the phone. We took a very conservative approach and didn’t order too many.”
Incidentally, the Passport also sold on Amazon within hours of going on sale. Guess there is quite a bit of love out their for BlackBerry after all… 

Red BlackBerry Passport Now AVAILABLE In UK 

The BlackBerry Passport (in sexy red) is now available SIM-free in the UK from retailer Clove. The handset costs £525 with VAT and, as you can see in the image below, it really does look rather snazzy with its red QWERTY keyboard. 
Clove sells all three versions of the Passport, so if red’s not your thing you can also get it in white and bog-standard black. Personally, we’re all about the red on –– it looks fantastic. 
“The BlackBerry Passport introduces a great deal of innovation. Firstly you will notice the fact that the device has a square design. BlackBerry has designed the Passport to move away from the traditional dimensions associated with smartphones. They have done this to increase the width of the screen making it easier to read emails and view information,” reads Clove’s product description.

BlackBerry Passport Review: Display 

The Passport’s display is a 4.5in 1440 x 1440 pixel IPS LCD setup and is the best display I’ve ever seen inside a BlackBerry handset – bar none. BlackBerry chose this resolution and aspect ratio (1:1) for a very specific reason: normal mobile phones display 40 characters across their screens, but with the Passport’s extra width you get 60 characters, which makes reading things like eBooks, webpages and - BlackBerry’s favourite - spreadsheets, A LOT easier. Or, if you prefer, better, by showing you more of what you’re looking at. Either way, it’s a good thing, as you can see below:
With regards to clarity and colour production, the HD-grade panel also delivers the goods. Colours look fantastic with excellent contrast and lots of detail. Text appears crisp and there’s no hint of pixilation anywhere, whether on the web, in an app, or when reading an eBook. Viewing angles are great too, and the Passport also performs well in direct sunlight –– unlike my current Nexus 5. But this was always going to be the case, as what you’re looking at is an HD IPS LCD panel.
The only real downside of this setup is to do with video, which is affected by boxing on account of the Passport’s 1:1 aspect ratio. This isn’t ideal by any stretch of the imagination and makes TV shows and Films a bit of a no-go on the Passport. Quick YouTube sessions are fine, but the Passport does lose out to other more traditional 16:9 aspect ratio handsets in this regard. 

BlackBerry Passport Review: Hardware & Specs

Inside the Passport you’ll find Qualcomm’s Snapdragon 801 chipset running alongside 3GB of RAM and an Adreno 330 GPU. That’s a pretty ferocious setup even by Android standards and makes for one hell of an experience in the day to day. Even more so when you factor in that BlackBerry, like Apple, has complete control over the software and hardware inside its handsets, which always translates in to a smoother, more power-efficient experience for the end-user. And the Passport is no exception to this rule.

Base Stations and Masts

How It All Works

What Is A Cell?

There are three types of cells: macrocells, microcells and picocells.
macrotwomacrocell provides the main coverage in a mobile network. The antennas for macrocells are mounted on ground-based masts, rooftops and other existing structures. They must be positioned at a height that is not obstructed by surrounding buildings and terrain. Macrocell base stations have a typical power output of tens of watts.
  • current and future customer call use because each base station can only support a limited number of calls simultaneously
  • the physical terrain of an area as radio signals are blocked by man-made and natural obstacles such as buildings, trees and hills
  • the frequency band in which the network operates can affect cell size - normally the higher the radio frequency (as in 3G technology) the smaller the cell
The cells in the third generation (3G) network are smaller because 3G uses a higher radio frequency. These cells also expand and contract in size depending on the number of simultaneous calls being made. For this reason, 3G cells have to overlap more than 2G cells.

Expanding The Mobile Network

More base stations were built to enhance the infrastructure for 2G and 3G mobile phone networks; operators are using the existing base station network as far as possible for 4G antennas, although some additional sites will be needed in rural areas.
New base stations are required as each cell can only support a finite number of mobile phone calls at any one time. If there is a high customer demand in a cell, greater capacity is needed to enable more calls to be made. This can be done by placing another mast in between the existing cells and creating additional smaller cells.
3G networks use smaller cells because they have to support the transmission of large amounts of information and operate at a higher frequency. 3G cells also expand and contract in size depending on the number of simultaneous calls being made. For this reason, 3G cells overlap more than 2G cells. 4G networks operate on 800MHz, 1800MHz and 2600MHz. 

Site Sharing

Site sharing is when two or more mobile phone operators agree to put their base station antennas on the same structure, such as water tower or roof-top. Mast sharing is when the antennas are put on the same mast.
Operators try to share sites whenever possible. However, it is not always a viable option. Shared masts are normally taller and have more impact on the environment because they have to accommodate two or more sets of antennas. The more antennas that are clustered together, the higher the overall radio frequency emissions are likely to be. Further, the radio frequencies that different mobile network operators use are not always compatible and could interfere with existing antennas.

Bluetooth Technology

Bluetooth is a technology specification designed to eliminate the cables and infrared links used to connect disparate devices. Its aim is to provide small design, low-cost, short range wireless interconnectivity between, for example, laptop computers, mobile phones, headsets, watches, digital cameras and cars. It also enables close-range applications in public areas like e-cash transactions.
Based on low power radio frequency technology using 2.4 GHz spectrum and a power level of 10mW, the data rate is almost 1Mbit per second and the range is approximately 10 metres. The technology enables users to connect a wide range of computing and telecommunications devices easily and simply, without the need to buy, carry, or connect cables.
It also delivers opportunities for rapid ad hoc connections, and the possibility of automatic, unconscious, connections between devices. It will virtually eliminate the need to purchase additional or proprietary cabling to connect individual devices. Because Bluetooth can be used for a variety of purposes, it will potentially replace multiple cable connections via a single radio link.

CEO of African telecom giant MTN resigns as $5.2 billion Nigeria fine looms






CEO of African telecom giant MTN resigns as $5.2 billion Nigeria fine looms

 

 
 
 
JOHANNESBURG - The CEO of Africa's biggest telecommunications company resigned on Monday because of a $5.2 billion fine meted out to from MTN Group's Nigerian subsidiary.
Sifiso Dabengwa was quoted in a company statement as saying he resigned "due to the most unfortunate prevailing circumstances occurring at MTN Nigeria."
Former group president Phuthuma Nhleko will act in his place for the next six months, the company said. Nhleko promised to "proactively deal" with the Nigerian Communication Commission, the regulator that fined the subsidiary for failing to meet a deadline to deactivate 5.2 million unregistered cellphone SIM cards. It's considered a security threat in Nigeria, where authorities say cellphones are used to co-ordinate suicide bombings and other militant attacks by Boko Haram Islamic extremists as well as in rampant kidnappings and armed robberies.
The share price of the company based in South Africa and listed on the Johannesburg Stock exchange has lost about a fifth of its value, according to South Africa's Business Report.
"Shareholders are advised to continue to exercise caution when dealing in the company's securities until a further announcement is made," MTN said.
On Monday, the price dipped on news of Dabengwa's resignation. When the fine was first announced at the end of October, MTN's share price tumbled. Last week, the Johannesburg Stock Exchange halted trade of MTN shares until the company assured shareholders that it was negotiating the fine with Nigerian authorities.
Nigeria's 60 million-plus MTN cellphone subscribers provide about one-third of profits for MTN Group, which has 233 million subscribers in Africa, Asia and the Middle East, according to the company website.

Sony Xperia Z5 review Three months since Sony's last flagship phone, the next one has arrived. So what's changed this time?

Sony releases expensive phones at a rate of knots. It seems only a few months since we reviewed the Xperia Z3+ because, heck, it was. Just three months on Sony gives us the Sony Xperia Z5. The Z3+ is already old news. If you bought one, we feel your pain.
Where’s the Z4? The Xperia Z3+ was released as the ‘Z4’ in Japan: the name’s already taken.
Unsurprisingly, there’s no grand innovation with the Xperia Z5. Sony is gunning for that with the even more expensive Xperia Z5 Premium and its 4K screen, which hardly ever renders at 4K resolution. Oops.
This more sensible mobile doesn’t hit us like the Samsung Galaxy S6, which was as refreshing as a morning dip in an ice pool. However, it’s a decent choice if you can’t stand the thought of siding with Samsung.

A GLASSY AFFAIR

image: http://images.cdn.stuff.tv/sites/stuff.tv/files/styles/big-image/public/brands/Sony/Z5/Review/Hands_On/sony_xperia_z5_review_top_01.jpg?itok=6RK6hXTU
Sony can’t seem to stand by a phone for much longer than it takes to make a cup of tea, but it still loves the metal and glass boxy design it has been touting since the Xperia Z series began in 2013. You get glass on the back and front, metal on the sides and little bungs of plastic on the corners, so any impacts don’t head straight to the glass on the back and turn it into a fractured spider’s web.
It’d be a shame if that happened too, because the Sony Xperia Z5’s back glass in particular is quite lovely. It has a frosted finish unlike the earlier Z-series glossier phones, which both feels more refined and avoids any scratches becoming too apparent.
The Xperia Z5 I’m checking out has a dark green finish, but you can also get it with gold or black back and sides.
It’s a good look, but the feel of the phone isn’t best-in-class. The sides of the Xperia Z5 actually stick out from the glass back just a fraction, and it’s enough to give the rear a kinda sharp feel. It doesn’t have anything like the smoothness of the HTC One M9 or Samsung Galaxy S6.
We’re even at the stage where a 7.3mm-thick phone like this can feel slightly chunky, because that thickness extends across the whole width of the phone. The Huawei Mate S makes it feels like a pork pie fan by comparison. A teeny-tiny bit fat and a bit sharp isn’t the best combo for a £550 phone.
As ever with this sort of thing: try to get your hands on the Xperia Z5 and the competition if you can.

EXTRAS? NO EXTRA ££

image: http://images.cdn.stuff.tv/sites/stuff.tv/files/styles/big-image/public/brands/Sony/Z5/Review/Hands_On/sony_xperia_z5_review_flap.jpg?itok=NrAHCfEO
There are some great side bits to compensate you, though. Unlike the top Samsungs or the iPhone 6s and 6s Plus, the Xperia Z5 has a memory card slot. With 128GB cards available for under £50 and 64GB less than £20, it’s a media hoarder’s delight. There’s 32GB storage built-in too.
The Xperia Z5 is also waterproof. There’s been quite a bit of fuss recently about Sony saying you shouldn’t really submerge its phones, even though it has been showing them off hanging out in fishbowls for years. “We recommend not submerge our Xperia Z5 in water,” is the official line.
Why? Waterproofing is provided by little rubbery seals, not magic. And tiny little bits of rubber are fallible. Some have gone as far as to suggest overheating has caused bits of the seals to melt but… we’re not even going to go there.
If you want to take photos of the small grey fish you’re likely to see while snorkeling on your hols, get a GoPro with a waterproof case rather than an Xperia Z5.
The phone's most notable new hardware feature can be found on its side. What looks like an oversized power button is also a fingerprint scanner. Right now it doesn’t do much beyond unlocking the phone, but it works very well. It’s neat that Sony has managed to make it not feel like a 100 per cent ‘me too’ job as well, in bunging it on the side.
A front-loaded scanner is still a bit more convenient because it keeps you thumb even closer to the screen. And I have found myself using the passcode instead at times as a result. But it’s still a good scanner.
