No other Android smartphone currently protects users against security vulnerabilities and cyber threats as well as BlackBerry's DTEK50... Apart from the extensive security features, BlackBerry's DTEK50 remains to be a solid mid-range smartphone. It convinces with a bright, Full HD panel, decent SoC performance, powerful stereo speakers, and a decent battery life.

It might appeal to the business customers with the type of security the company is giving, but for a regular people, it is just another Android smartphone.

The BlackBerry DTEK50 is definitely not perfect. It has its issues; most notably battery life and performance. However, the handset - for its price and features - is very impressive.

If it is security and functionality you are after- this is the phone for you. The camera could have been better and although the display is great, the audio reproduction quality and the battery life pull it back slightly from being the great streaming device it could have been.

Whilst some might consider the lack of a physical QWERTY keyboard and a fingerprint sensor losses, but (...) you don't just get a competent, elegant-looking Android device, but you also get the peace of mind afforded to you by BlackBerry's know-how in the security industry.

Android Authority | Lanh Nguyen

The Blackberry claims that the DTEK50 is the world's most secure smartphone, and if security is your number one priority, Blackberry's second attempt at Android won't let you down. However, it falls short in a lot areas that prevent it from being a great smartphone.

BlackBerry DTEK50 is definitely one of the more secure Android smartphones out there. Its security enhancements ensure that your data remains safe and the design is also really good... with the enterprise-grade security of BlackBerry, the DTEK50 is definitely worth buying....this is value-for-money smartphone.

While the DTEK50 offers far better hardware than previous budget BlackBerries, it just isn't in the same league. It seems as though TCL slapped the BlackBerry logo onto one of its own products. When it comes down to it for most buyers, this is just another Android phone.

Phone Scoop | Eric M. Zeman

You'll find the DTEK50 nails most of the basics. It features a good screen, solid wireless performance, and excellent battery life. Some may dislike the sealed battery, but support for memory cards is a bonus.

Mashable | Jason Cipriani

Even diehard BlackBerry fans may not care for this mediocre phone. Unless you really, really care about security... This is a very niche device built for a niche set of users, most of which work for big corporations or the government.

Pocket-lint | Cam Bunton

BlackBerry has added some valuable additions to its software, but without the reliable performance we'd like, the DTEK50 can be a frustrating overall experience. It has a nice screen, decent camera and feels great in hand, but there are better phones out there for a similar price.

Mobile Syrup | Ted Kritsonis

It's easy to see how the DTEK50 may have been more impactful had it been released as far back as 2014. A mid-range Android phone like this would have been an interesting choice for consumers priced out of the premium market, and in turn, helped the company's sagging hardware division.

Tom's Guide | Mike Prospero

The DTek50 is a good option for those worried about security, but it's not the greatest smartphone, even at this price.

The Verge | Chris Welch

The DTEK50 is secure, sure, but it's underwhelming in most every other regard. If BlackBerry could only marry that security with better hardware, then it'd have a far more compelling package. Until then, it fails to stand out in a competitive field of midrange smartphones.

TechPP (Technology Personalized) | Nimish Dubey

It is a good device, but nowhere near the greatness that BlackBerry needs. And while it is affordable by BlackBerry standards, those standards still seem a trifle out of sync with ground reality, especially taking the new generation budget flagships into consideration.

AndroidPit | Scott Adam Gordon

If you're looking for the most secure phone in the world then you're sure to be interested in this. If you already know some smart ways to protect an Android device and want a higher performance product at the same price, then you should look elsewhere.

The Inquirer | Matt Farrington-Smith

The BlackBerry DTEK50's hardware is almost irrelevant, as the magic lies in the software.

CNET UK | Sean Hollister

... the DTEK50 feels a good bit slower than I'd hoped. It always feels like there's a slight delay before the phone opens the app, summons the keyboard or loads the link I want. Raw performance numbers show the DTEK50 performing at about the same level as the Moto G4, a phone that costs less.

V3 | Matt Farrington-Smith

BlackBerry still rules the roost when it comes to enterprise-ready security, but that price is less forgiving when it comes to specifications. There are rumours of a further Android-based handset being unveiled later this year, so maybe you're better off waiting.

Trusted Reviews | Max Parker

Sluggish performance, poor battery life and a dull design make this privacy focused device difficult to love – even if it benefits from some really neat software tweaks.

Stuff | Andrew Williams

An unimaginative phone with a price that overvalues BlackBerry's software extras - unless you're CIA-level paranoid.... The hardware is fine, the performance is fine. But at this price tag you should hold out for more than just 'fine' - particularly if you're not in love with an Android injected with some BlackBerry DNA.
