TechforTheTechie Review: The OnePlus5


The budget super-phone you never knew you wanted… until now!

THE PITCH
If you're racing to catch a bus or train, or just glancing for 2 mins at your phone, here's my elevator pitch…

Grunt. Speed. Elegant styling. Ridiculously quick. Super-affordable. Sexy-in-Black. And, Oh the camera(s) on this device... Crisp quality pictures, and an even sleeker 'portrait mode’. Easily kills all of the competition on the majority of benchmarks, and all that for a comparatively 'diet' price point.

Buy a OnePlus now!
Need further convincing? Read on.


STYLING AND DESIGN

The OnePlus5 in Matte Black (snippet of Carbon Fibre case top-right)
The OnePlus5 comes in a sleek black.
It has a very sturdy feel and design with an all metal chassis. And a burnished non-reflective matte coating.
It also has a decent weight to it while still feeling very light.

One particularly useful design cue is the side button for muting notifications. The left side of the OnePlus5 has a super-handy slider button for doing just that. And has three settings: one to mute all notifications, one to allow all notifications, and a mid-level to allow only priority notifications.

I've found this very handy and use this all the time especially when you're in those awkward moments where you quickly need to adjust this (like when someone else's phone rings out in the middle of a meeting)!


THE CAMERA(S)
The OnePlus5 is revolutionary in that of all the phones with dual cameras released around the same period (we're talking early to mid-2017), OnePlus decided,
“Nah, do you. We’ll do it differently”.

It comes loaded with a dual camera setup at the back of the phone.

One 20MP sensor and an accompanying 16MP sensor primarily to support 2X optical zoom with no loss of image fidelity. It also does pretty well for itself in low light shots.

It also has a very crisp 16MP front-facing camera for taking #Selfies
#PortraitMode uses some form of artificial intelligence algorithm to apply a blur effect on photos to make the subject stand out better and give it a more refined sense of depth-of-field in focus. It works automatically and all you need to do is just switch to that setting in camera mode and it does the rest for you.


Portrait Mode on the OnePlus5 really makes the subject standout

It does still need some work though as in some cases it tends to blur the edges of the primary subject as well or get confused by highly contrasting colours like black text on a light background. All-in-all, ‘Portrait Mode’ on the OnePlus5 does an amazing job most of the time.

Focus is sharper and Depth of field narrower in Portrait mode

SCREEN (Let's talk about Notch… baby)

So.This one doesn't have a notch (*phew*... the OnePlus 6 will though... pictured)

‘The notch’. Hate it or like it, is the next smartphone trend we’re seeing primarily in 2018. (I’ll blame Andy Rubin for even introducing the concept with the Essential phone in 2017. The iPhone X made this even more popular. A few other manufacturers have followed suite since… including OnePlus).
It’s that little dark portion at the top of some smart phone screens housing the front-facing camera and other sensors with phones where the manufacturers are beginning to push for less of a bezel at the top and the bottom.
It's the same reason why one key difference between the souped-up OnePlus5T and the OnePlus5, is that the fingerprint reader was moved to the back of the phone.

We all like the extra screen 'real estate’ this affords us. The notch, however is a very divisive issue. The good thing is, after some protests from the OnePlus faithful, Carl Pei and team decided to introduce a software option to hide the notch on the soon to be released OnePlus6. Effectively including bars of black pixels on either side of it to give the illusion of a flat-lined bezel.

So if you do not like the notch, rest easy. It isn't a problem on the OnePlus5. It won't be a problem on future OnePlus iterations.

Notch aside, You get a 5.5 inch amoled display on the OnePlus5. Generous for doing things like gaming, watching videos or even reading and editing documents on the go. It feels more natural than using a small screen and doesn't hurt the eyes having to strain excessively like you would on a smaller phone.

The OnePlus5 screen has a 1920 x 1080 pixel resolution which ensures that you get a crisp, clear display at all times and in all conditions. Surprisingly, it's also very good in high-exposure to sunlight with minimal reflection (just remember to keep the auto-adjust setting on for screen brightness)

Video
Image stabilization is standard and works very well on the OnePlus5. You can also shoot crisp, clear 4K video easily. Just watch out for memory usage though if you will be shooting a lot of 4K video.

Split-Screen
Yup, it means what it says.
You can use two apps side-by-side (or one above the other depending on your phone orientation in portrait or landscape mode). Pretty cool feature. Although, haven't had many instances where this has been an absolute necessity. Feels to me in general like the sort of feature that you'd really find very useful on a much larger screen like on a tablet.

DASH CHARGE (A full days charge in 30 minutes!)


Shall I say more?
Okay.
I will.

If there's any good reason to get a OnePlus, it's for this reason. The OnePlus5 for instance in just a 30 minute charge, gives you enough power for a whole day!
Gone are the days of charging overnight. You can simply plug your phone in when you wake up, and by the time you're ready to leave for work, school, the school-run..(or whatever else gets you up daily), your device is charged up enough to get you through the day.
OnePlus proprietary Dash Charge technology means that it's still the best in the market in this area making it an easy decision to go for this device for that reason.

There are also no issues with heavy usage like calls and gaming while charging causing overheating. This is a known issue with most other smartphones. In the worst of cases, some even exploding and causing injury to the users.
This is another core difference between Dash Charge and other Fast Charge technologies as its energy use is way more efficient than others.

FINGERPRINT READER AND FACE UNLOCK
I will not elaborate. There is no need to. The fingerprint reader is quick. Very very quick. (Less than half a second). I have experienced absolutely no lag using it to unlock my phone.
Face Unlock seems even quicker. It has also been noted to easily be quicker than the iPhone X’s Face ID. It works, in fact, almost instantaneously!
It is worth noting also that from a security perspective, the iPhone X maps specific points on the face using LIDAR technology to create a 3D image.
The OnePlus Face Unlock on the other hand uses a flat 2D representation of your face. This doesn't mean it is easily fooled for instance by a photo for instance and in fact it is very difficult to trick it.
Try wearing dark glasses even and note that it doesn't unlock. There is a very detailed analysis of the facial biometrics that is done on every unlock attempt before access is granted.
Quick. Effective. Secure (Enough).

STORAGE, RAM & SPEED
I personally opted for and reviewed a 128GB onboard storage version with 8GB of RAM.
This phone has more processing power and memory than my work computer!
It is so ridiculously fast, and the OnePlus Oxygen OS so smooth to use, that I have genuinely forgotten what it's like to use a “laggy” phone.

There is a cheaper option as well with half the storage and memory, 64GB x 4GB RAM. For £50 extra, I think the extra memory and storage space is definitely worth it, especially for a super smartphone they costs you only £549.99.
Also, if you create a lot of media like pictures and videos you'll appreciate the extra storage even more.

ACCESSORIES
OnePlus, with every phone release, does a lot of work to ensure that there are good host of accessories available at launch. An added bonus is the very detailed styling and range of options made available (and designed) by OnePlus.
Over the years, the catchphrase “Designed by OnePlus” has come to be denoted with style, quality and elegance. Three words that are synonymous with the brand.
One of the all time favourites for OnePlus has been its carbon fibre case.

WARRANTY, REPAIRS & TECH SUPPORT
I had a slight issue with the volume rocker of my OnePlus5 getting stuck (sometimes) after just a few months use. Quite unusual.
Although support staff were very nice, unfortunately I was told that this was not covered in my warranty and I'd have to pay £100 to get this sorted. I found this a bit odd given than the volume rocker on any phone must be one of the most difficult things to actually damage, even if you were trying to.
All-in-all, not too fussed about it, however, this is one area in general (warranty and post sales support), that a few users have been known to complain about.
It wouldn't be fair of me not to give you the 'full picture” here.
I do know a fair few though who have had absolutely no issues with having repairs done with OnePlus.

FREE DELIVERY
As an added bonus, OnePlus delivers for all orders over £40 in the UK for free. A minor detail, but noteworthy.

WE TECHIES JUST LOVE ONEPLUS
OnePlus is a company that from day one has always striven to make themselves different. To be simply incomparable.
A good example of this ethos is in the innovative technology that is ‘Dash’ Charging.
As I write this review on a flight to Berlin, I am only able to do so on my OnePlus5 (with ample battery to spare), because I was able to juice up from 34% to just about 79% battery life in the 35 or so odd minutes it took me to wake up, freak out that I'd be late for my flight, get ready, pack my charger and bounce.
I work in a highly technology inclined environment. (So much so that the name of my team at work actually has the word 'Techology’ in it). I was one of the OnePlus pioneers in my team. (Myself and someone else I'll simply refer to as 'The Bearded One') 😉
I had a OnePlus2 at the time. The Bearded One stuck to a OnePlus1 - the first iterant of the device.
Over time, as more and more of my techie colleagues started to ask questions, handle our phones, play with them… we saw a shift.
In less than a year, almost all of my team, who would normally be iPhone or Core Android users have slowly come on board with OnePlus. We got to a point where there were even fewer people not using a OnePlus device.
This says a lot for the virtues of OnePlus devices in general for being very sturdy phones, but even more so, trusted by the tech community. (Another old friend of mine even went as far (and crazy) as configuring his OnePlus1 for cybersecurity penetration testing… (Yes. You can actually do that!).

I'm really looking forward to getting hands-on with the soon to be released OnePlus6. A killer device the OnePlus5 is and it's big brother the OnePlus 5T even more so. It's exciting and frankly mind-blowing to think how much more better the 6 will be considering how crazy-positive the OnePlus5 and 5T already are!

See you at the OnePlus6 launch event on May 16th!

#TechResponsibly


We all have a profound social responsibility to each other with our use of Technology



by Paul Ekwere

We are at a pivotal point in the history of the human race.
Advances in the areas of artificial intelligence, robotics, data analytics, big data, genomics, mean that as a human race we can do anything, go anywhere, be anywhere, experience it all, achieve great things.

Technology and its many advancements however come with risks. Present and future risks.

The dearth of privacy, the further potential division of society into further distinct and further apart classes based on race, wealth, increasing unemployment, natural (or customised) genomic makeup, cyber crime and advanced cyber warfare to mention but a few are all very real risks that come with our technological advancements.

I could go on. I won't.

Technology can be used for a great many other beautiful things too. A unending list of good things. And in fact, it already has.

Our technology of today, has the power to magnify our good or ill will on an astronomical scale, affecting all around us including ourselves, and further accelerating the course of human history for better, or for worse.

My advice to all including self, is simply this.. Think of the impact... Think of the greater good... Think of Societal benefit more than you do personal gain; Because as with any 'tool' ever employed by homo sapiens, it starts with the heart... It starts with your prime intentions... It starts with you.

Epilogue: My inspiration for this short piece begins with a lazy sunday morning waking up and feeling awful with a nasty sore throat that wasn't there when I (eventually) went to bed at 3am. I decided to take my medication, lie down on my couch and pick a random movie to watch. Netflix seems to have studied enough of my data on movie and series watching patterns to know that I'd love the movie 'The Circle'. I did. I also found it very inspiring. I suggest you watch it too.

Ah, Netflix. You know me so well. A little disturbing when you think about it. Ah well, Touché.

Wanna Cry? Don't. Protect Yourself


*** Bite-sized Security Update ***



by Paul Ekwere
___________________________




Cybersecurity is important.

Nothing brings that to bear more than the WannaCry malware which last week Friday, (12th May, 2017) "hit over 200,000 computers in 112 countries across 28 languages", including critical systems relied on by public services such as the NHS in the UK.

If you're using an older version of the Windows operating system, you may want to download a security patch and update your system's security. You may also want to invest in an up to date antivirus package.

Dowload the latest Microsoft security patches here:

Tech for The Techie: The Data Science Guide I never had

An Introduction to Data Science - Where do I begin?




 by Paul Ekwere
___________________________


It’s a very difficult thing to be interested in a very broad and ironically esoteric topic such as data science and know where to begin your research. The most difficult part of any great journey is taking that first bold step.

Unfortunately, not many of us know what that first bold step should be.

Welcome to Data Science 101.




There are quite a few varying opinions on what 'data science' is. Interestingly, the most apt definition I have read in recent days was on wikipedia.

Data Science (definition): " Data science, also known as data-driven science, is an interdisciplinary field about scientific methods, processes and systems to extract knowledge or insights from data in various forms, either structured or unstructured, similar to Knowledge Discovery in Databases (KDD)."

As such, a data scientist, may be categorized as one who employs scientific methods, processes or tools to analyze structured or unstructured data to produce results that make the tasks of high level analyses, and drawing inferences and conclusions from the data simpler.

Data science is something I do everyday. It is something I have always done.
From my geeky love of weird sequences such as Fibonacci and hours spent as a pre-teen on my own creating my own unique logical sequences and custom cryptographic code, to my years as that-guy-in-class-that-doesn’t-use-a-calculator-to-do-his-math-but-rather-does-it-all-in-his-head, to my late teenage conquests of being that-guy-who-solved-the-rubik’s-cube-in-1-min-27-secs-flat-while-barely-even-looking-at-it-the-whole-time; to my latter years as an aerospace engineering student / honours graduate & now doing full-fledged data science work as a professional service, I have always been involved in one way, shape or form, in data science.

In my life as a data scientist, I have found that some things just come naturally to me. Other things, not so much. One thing though has stayed consistent. If I want an answer, I search for it. I find it!
If I’m puzzled by a problem, I ask, I read, I google, I annoy, I pester, until I solve it or find a solution!

Data science is exactly this!

  Be curious.
  Feed your curiousity.
  Find a problem.
  Fix it (or learn 1000 ways it can’t be fixed)
  Repeat above steps.

For a lot of people though, the first step is the hardest. So I thought I’d give you a little nudge in the right direction. Awaken that curiousity if you will.

I read a lot of posts on data science, analytics, machine learning and artificial intelligence. I also post every now and then on these topics on my twitter or my flipboard microblogs.
Among some of the things I have been reading, I thought it would be helpful to compile a list of some introductory data science topics & blogs I’ve recently read that may help. A basic guideline I wish I had when I first started my career.

They are, (in no particular order):

The Basics

Intermediate to Advanced

I stayed away from Social Media for 7 days --- it didn’t kill me

...something else almost did. Read on to find out what!  ;)




 by Paul Ekwere
___________________________



Capture - phone screenshot.PNG
I decided not to use Social Media for a week.
Crazy?..... maybe…..  Impossible?...... nope! …. Cathartic? ……. Oh hell Yeah, without a doubt!

So what led me to this decision?.... I’m glad you asked! :)

Every day of our lives, we are inundated with an endless stream of notifications on our devices --- laptops, tablets and smartphones…. especially the smartphones!
Barely a minute passes by without the usual “X just liked your post on twitter”.....”Y and 63 others liked your picture on Instagram”...”Your post on 500px is now upcoming”.... “ Z mentioned you in a comment on Facebook”.... “John Doe and 9 others viewed your profile on LinkedIn”.

It’s great to be ‘in the know’ and keep up-to-date on what’s happening. It does however have it’s detrimental effects. It’s easy to get sucked into this modern day convention, always needing to know everything right now! With some it gets so bad that you could develop psychological and physiological health problems such as ‘Phantom Vibration Syndrome’ or ‘ringxiety’ ---  a condition where the sufferer suffers a form of tactile or auditory hallucination caused by the false perception of one’s mobile phone (or other primary communication device) ringing or vibrating when it is not.
Yep! ‘Ringxiety’! --- it’s a real thing. Look it up. There’s loads of other really serious ailments that could come about from being addicted to mobile phones and the like. Another good example is text neck’.


I suffer from neither of these conditions.
For me, the decision to not use social media for a while came from a much simpler thought process.
You may not suffer any ailment as a result of time spent on tablets and smartphones but therein lies the problem itself (I said it already and you didn’t even notice) ----- TIME!

Using the american populace as a benchmark for the rest of us, it is estimated that we spend about 20% of all online time on social media with Facebook accounting for 14% of that time.
The average person has 5 social media accounts and spends a lot of their day poring through, consuming and generating even more content.

All of this amounts to valuable time. Time that you can use to do a whole lot more and be productive.
My epiphany came over the weekend reading the new book by South African comedian and TV personality, Trevor Noah titled ‘Born a Crime’. (fascinating read by the way, I think everyone should read this book!)
Trevor tells the story of his life, growing up as a mixed race kid in apartheid South Africa and the numerous challenges he faced, one of which was ‘street hustling’. He talks about how much useful time he wasted waking up every morning, expending a lot of energy, making just enough money to get by, and spending it all again, pretty much dialing back to zero.
‘Time wasted’
He used a very ‘colourful’ metaphor though.


And that was it for me. Talking to a very good friend about this later that evening the decision was an easy one to make. “Let’s experiment. One week. No social media. You in?..... Cool!”

Day 1
3 am. At a bar with some friends. Stood in the queue to use the loo. This is boring. What do I do now? No real conscious thought. Just force of habit…. Phone comes out. Whats happening on my Instagram ?...Oops!... *closes Instagram app*... phone back in pocket.
Hmmmmm…. This is going to be harder than I thought.

Day 2
I don’t feel so good. I really, really do not feel good.
No, it’s not the social media thing, I could care less. I’m in a lot of pain. Physical pain. Please tell me it’s not that blasted pharyngitis again! I can’t do this right now.
6:15pm - confirmed. Doctor says it is pharyngitis…. Again! *sigh*

Day 3
In bed. Very sick.  Hello painkillers.

Day 4
Still sick. Please go away.

Day 5
Netflix.
(Obviously) getting better.

Day 6
I'm back from work and my thumbs are itching. I've got quite a few notifications now on different social media platforms.
I've opened Instagram once and promptly shut it after remembering I'm not supposed to.
I'm still determined to prove to myself that you can live without some of these modern day accoutrements.
1 day to go Paulie … hang in there. Barely 24 hours to go!

Day 7
Gosh this house is a mess! Spring cleaning time. Funny, I’ve actually not missed social media that much. ….Okay, maybe just a little.

Day 8 (Freedom)!
Oh wait…
It’s 1:25 am? I can actually get back on social media now??? Meh!  It can wait. Going to bed.
Yawn. 9:25am. Need to take my medication.
OK. 9:40am. So what did we miss?
  • Facebook (23 notifications, 2 new friend requests)
  • My Twitter (1 like, 1 mention, oh and some guy I know has joined twitter. Great. I needed to know that)
  • LinkedIn (12 notifications: some people published posts, some people viewed my page, some people commented on posts I’ve previously commented on.)
  • 500px (4 likes)
  • My Instagram photography page (13 notifications in all, 2 comments, 3 new followers, a couple of likes)
  • My Instagram art page (1 mention, 3 new followers, 1 like)
  • Youtube (22 notifications)
(Oh yeah, Donald Trump got inaugurated on Friday)

10:12am well. Doesn’t seem like I missed that much after all.


Closing Statement
It’s funny how dependent we get on something without realizing it. Apart from being ill for the majority of my self-imposed social media exile, I did notice that personally, I had a lot more time to catch up with family, read books and even when not doing much, my thought process seemed to be a lot clearer with fewer distractions.


All-in-all, it’s really not a big deal not using social media for a while. You can actually survive with minimal to zero social media use. It is good for a lot of things.


Use it. But don’t let it use you!
I definitely recommend everyone tries this at some point. I guarantee you’ll be a lot better for it.


Just…. Don’t tell your friends.
Especially if they’re all sat round a table with you and have their phones on them!
