BlackBerry DTEK50 Review – The Most Secure Smartphone


In the late 1990’s when the smartphone industry was in its infancy, the BlackBerry brand was very popular. However, technology has significantly advanced since then but the BlackBerry brand hasn’t been able to keep up with the advancements in technology. For this reason, BlackBerry hasn’t been a viable option for many smartphone users in years.

BlackBerry DTEK50 Introduction:


Last year BlackBerry launched their very first Android smartphone, this was a step in the right direction. There were many smartphone users who anxiously awaited the BlackBerry PRIV.


But the PRIV did not live up to its expectations, the PRIV has its pros and cons like every other smartphone. However, it was overpriced and the camera was not up to par with the other smartphones that were currently on the market at that time.


The BlackBerry DTEK50 is BlackBerry’s second attempt at greatness in the smartphone industry.


The main selling point for the BlackBerry DTEK50 is its security. BlackBerry claims that the DTEK50 is the most secure smartphone in the world, that’s great because everyone wants a secure phone.


However, the avid smartphone user will expect much more from their phone, will the DTEK50 live up to those expectations? I will answer that very question in this in-depth BlackBerry DTEK50 review.


BlackBerry DTEK50 Display:


The DTEK50 comes equipped with a 5.2-inch IPS LCD display screen, Full HD resolution, and a pixel density of 424 pixels per inch (ppi). The display screen is good but it doesn’t look as rich as the display screen on the Galaxy S7 Edge or the HTC 10 smartphones.


However, the display screen is bright and the picture quality never gets distorted even when viewing the screen from different angles.


The display screen has quite a bit of color and contrast, the 1080p is high enough to provide a great viewing experience whether you’re surfing the net or watching videos you will have an enjoyable experience.


BlackBerry DTEK50 Design:


When it comes to the design I think that BlackBerry could have been more innovative with the DTEK50. The design is not bad at all, however, it was modeled after the Alcatel Idol 4s, both phones look very similar.


The only thing that distinguishes the DTEK50 from the Idol 4s is the back panel. The back panel of the Idol 4s is made of glass and the back panel of the DTEK50 is made of a textured plastic.


The textured plastic material is great because you will not have to worry about the back panel collecting fingerprints, and the material provides great traction when holding the phone in one hand.


The DTEK50 has a microSD card slot which is located on the right side of the phone along with the SIM card.


The headphone jack is located at the top of the phone and the micro USB port is located at the bottom. The volume rocker is also located in the typical position at the right.


Directly below the volume rocker is a circular button which BlackBerry calls the “convenience key”.


You have the ability to program the convenience key button to do a number of different things such as controlling the LED flash, composing an email or text message, launching an app, and toggling Wi-Fi.


The convenience key can be used to lock the phone as well, however, it cannot be used to wake it.


The power button is located in an unusual position at the upper left side of the phone, this will probably take a while for the avid smartphone user to get used to.


One of the nice features of this phone is that you have the ability to double-tap the screen to wake and sleep the phone.


This is a great concept, sometimes it works exactly the way it’s supposed to but sometimes it doesn’t, sometimes it’s a bit slow to respond. Never the less it’s still a useful feature to have on a phone.


BlackBerry DTEK50 Performance:


The DTEK50 has 3 GB of RAM an octa-core Qualcomm Snapdragon 617 processor, which is clocked at 1.5 GHz, and backed by the Adreno 405 GPU.


These are some of the things that you would expect in a mid-range phone in 2016. If you’re someone who only plans on using your phone to talk, text, surf the web, send emails, and watch videos.


Then the DTEK50 will  perform well for you, the phone runs smoothly when opening and closing apps and even while multi-tasking you will not notice much lag.


However, if you’re someone who enjoys playing games on your smartphone then that’s a different thing altogether.


I was able to play a few games, however, when starting a game the load time is a bit long and the phone has a tendency to lag while playing games. I don’t think the DTEK50 will be a great fit for an avid smartphone user who enjoys playing video games on the phone.


BlackBerry DTEK50 Hardware And Battery:


The DTEK50 comes with 16 GB of internal storage this is somewhat typical for a mid-range phone.


However, the DTEK50 has a microSD card slot which is expandable up to 256 GB. So this is a viable option if the 16 GB of internal storage is not sufficient.


One of the best things I like about the DTEK50 is the way the speakers are setup. The DTEK50 has dual-front facing speakers as well as dual-rear facing speakers which provide good sound quality.


Even when I cranked the volume up as high as it goes the sound quality remained the same, BlackBerry did a great job on this.


The DTEK50 comes with a 2,610 mAh non-removable battery, this was a bad decision on the part of BlackBerry.


The battery will last for one day of moderate use but if you’re someone who uses your phone heavily on a daily basis the phone will not last a full day. The phone comes with Qualcomm Quick Charge 2.0 so it will not take a long time to charge.


BlackBerry DTEK50 Camera:

The DTEK50 comes with an 8 MP selfie camera with a f/2.2 aperture, a 13 MP primary camera with a f/2.0 aperture, phase detection autofocus, and a dual LED flash.


The camera app is very simple and straightforward, you get the following shooting modes: photo, video, and panorama.


There is an HDR Auto mode, and a built-in manual mode which gives you control of the white balance, focus, ISO, shutter speed, and exposure.


This camera does not take the best photos, especially when using the zoom feature the picture quality is not as sharp.


When taking photos in a dark setting the camera has a hard time focusing and the image quality gets a bit distorted.


However, when shooting pictures in a well-lit setting without using the zoom feature the quality of the photos are a bit better.


My Final Thought:


The BlackBerry DTEK50 is a mid-range smartphone, the main selling point for this phone is the security that it provides.


BlackBerry claims that the DTEK50 is the most secure smartphone ever. That’s good, however, the camera and the battery needs to be improved.


The BlackBerry DTEK50 can be purchased for $300 US dollars and it can be used with T-Mobile and AT&T. Please let me know your thoughts on the BlackBerry DTEK 50 in the comment section below.



  1. I appreciate this review! I am a big fan of Blackberry, however with how far they have been lacking as of late, as well as their reputation, I have been reluctant to purchase one. If the Blackberry Classic was of better quality, I would’ve purchased that in a heartbeat, but I was sold into purchasing an LG G4.

    That being said, there isn’t much of an excuse for a poor camera and poor battery life for such a new phone. Thank you for making my decision for Blackberry in the future easier.

    • You’re welcome Dylandb, the classic BlackBerry phones were of better quality. BlackBerry needs to do a better job with their phones in the future to regain their position in the smartphone industry.

  2. Thanks for your honest and thorough review. My wife and I are in the market for new phones, I know Blackberry got rid of it’s old design but had no idea they had come out with the newer design that is similar to other smart phones. I think after reading your review that I agree, the blackberry seems to be missing something and definitely could have been better designed!

  3. Your site is very informative as far as Black Berry is involved. I like how you stated the pros and the cons. But, to be honest, all phones have the battery problem sooner or later. It is a great product though. Good work , Black Berry is a good brand.

    • Thanks Curtis, I think a good phone is supposed to have a good battery life especially when it’s new. It’s not a good sign when you have a new phone with a bad battery life.

  4. I really like your site. The information is solid and it seems like you do your research. The page you wanted the comment on is what I found very interesting though. Not for any bad reasons, I just didn’t even know that BlackBerry was still in business even, I though it was done. Keep up the good work!

  5. Hi Marvin,

    Thank you for the thorough review of the BlackBerry DTEK50.

    I have to say that I am a bit critical of BlackBerry not only because I have used the phones before, but I have been in charge of enterprise wide deployments of BlackBerry Enterprise Server!

    I am very happy to see BB move into Android phones. If that didn’t happen there would be even less apps for BB than there are for Windows Phone!

    It’s too bad the display is not as nice as the Galaxy S7 or HTC 10 phones, but I’m not sure the buyer of the DTEK50 is interested in the screen as much as security.

    The convenience key seems interesting. I’m not sure what I would program with it.

    I can see this phone for the middle of the road business phone, but I’m not sure anyone would want it as a personal phone.


    • Thanks for the feedback Britt, I don’t think the DTEK50 will be too popular among smartphone users, however, I hope that BlackBerry will do a better job next time around.
