 I just got the new Obi WorldPhone SF-1. Few weeks ago , i made a post about the launching event you can check it out here


The Phone is classy and will definitely compete strongly against Tecno and  Infinix. Here is a short review. I am so in love with this device.


The design is pretty minimalist with only two buttons, the
power/unlock button and the volume control rocker (which can also be
used as a shutter button when using the camera) on the left. On the
right side,you  have the SIM card tray slot that is a hybrid one, which is dual sim. However it is worthy to note that it has a slot for a nano sim which is pretty smller than a micro sim or a micro SD card slot.

Chipset RAM, Storage
Coming down to the stuff that matters to most buyers, the Obi
Worldphone SF1 packs in a 1.5 GHz, 64-bit, octa-core Qualcomm MSM8939
Snapdragon 615 chipset. Obi has generously included 3 GB of DDR 3 RAM
for the 32 GB model (2 GB for 16 GB) and allows for storage expansion,
via the previously mentioned hybrid SIM slot.


The smartphone packs in a 13 MP Autofocus (Sony Exmor IMX214) with an
f/2.0 aperture on the back and a 5 MP sensor up front; both of which
are accompanied by an LED Flash.

The primary camera’s quality was satisfactory
at best but it tends to overexpose. Colour reproduction is amazing, but
the camera presses for noise-free images, which lead to reduced details
while zooming in.Still then, it keeps things simple
with all the options easily accessible when needed. The front facing
camera does a satisfactory job and the flash really does help in low light
situations. Obi has thrown in a few more features like the Dynamic focus
(UbiFocus) and colour preserving ChromaFlash, OptiZoom.

Although Obi did focus on the LifeSpeed UI at launch, it seems to be
limited to just the launcher and the homescreen. LifeSpeed (with Android
5.0 Lollipop) seems to deliver what can be accomplished by any
third-party launcher (available from the Play Store) and as of now comes
with few customisation options such as the ability to customise the use
of the power button to end a call or answer a call using the home
button. Also included are some gesture-based Smart Functions such
as flip-to-mute.

Moving to the top we have a 3.5 mm earphone jack and a second
microphone along with a plastic insert for the antenna bands. Around the
rounded bottom, you will find the mini-USB charging port flanked by two
speaker grilles out of which only one is functional, while the other is
for aesthetic reasons.


The 3000 mAh battery that the Obi packs is supported by Qualcomm’s
Quick Charge 1.0 meaning that the battery does charge up quickly which is very good for the Nigerian Tech Scene.

On the connectivity front, Obi delivers with support for GSM, WCDMA
and 4G LTs. You get the dual SIM set up
which is basically a hybrid SIM tray so you get a 1 micro SIM + 1 Nano
SIM or 1 micro SIM + 1 microSD card set up. And then are the usual WiFi
options including Wi-Fi 802.11 a/b/g/n, Dual-Band, Wi-Fi Direct and
Bluetooth v4.0 with A2DP. The SF1 also packs in the standard A-GPS with

Coming to the stuff that really matters. Lifespeed that runs atop
Android 5.0.2 Lollipop is basically a skin that comes with nothing
special apart from the theme functionality, which can also be turned off
from the Display Settings.

We had a lot of expectations from Lifespeed, but sadly it is nothing
more than a third-party launcher that hides some Cyanogen
bits underneath (for a variety of reasons). While Obi confirmed that
they have not used Cyanogen OS, but a firmware developed in-house, we
could not help but notice that the File Manager, Messaging apps come
from Cyanogen.
All said and done, the Obi Lifespeed UI style that can be turned off
from Display under Settings does provide the device with a distinct look
from the lockscreen down to the icons on the homescreen that are
instantly recognisable and look unique. Talking about the lockscreen, we
wish that it could have been able to display some notifications other
than simply giving options to swipe to unlock (shown in the image
above), to open the camera or the dialer app.

The audio performance of the Obi Worldphone SF1 is great. Call
quality was good with the call volume on the earpiece speaker are loud
and the mic is good; as callers on the other end could hear
conversations loud and clear. The same can be said about the SF1’s
loudspeaker, that is placed under the right side grille at the bottom
end of the smartphone, it is sufficiently loud and does a fine job at
what it is supposed to do.
The SF1 scored pretty much in line with the rest of competition that
sports a Snapdragon 615 chipset. But you also have to remember that the
SF1 sports a Full HD (1920 x 1080 pixels) display, which should take a
toll on the GPU so you need to keep this in mind before you have a look
at the scores.
Obi Worldphone SF1 Benchmarks Screenshot 360 A
The hardware on board the SF1 delivered some commendable scores on
benchmarks despite my worries about the software ruining the user
experience. The Qualcomm Snapdragon 615 with the Adreno 405 GPU and 3GB
of RAM passed off as a great combination and the deal looks even sweeter
when you factor in the price tag.

The 13MP rear camera is a Sony Exmor IMX214 Sensor with an f/2.0
aperture that delivers a sufficient amount of detail in daylight and low
light captures. Obi has included three extra goodies in its camera
software that inlcude, UbiFocus a dynamic focus mode, OptiZoom
a multi-frame super-resolution photos that mimics an optical zoom and
the colour-preserving Chroma Flash. Clearly, all of these are software
tricks and while the OptiZoom and ChromaFlash mode proved their worth in
daylight scenarios, the UbiFocus mode did not.
Also not useful in the camera app was the HDR mode (result in the
second image above) that made captures far worse by overexposing them, I obtained better results with tap for exposure in the normal auto

Apart from the above mentioned camera modes, you get the standard
auto mode that does a great job and is quick to acquire focus and
process an image thanks to the great hardware.
Daylight shots are great and the engineers seemed to have managed to
squeeze out a good amount of detail from the 13MP sensor. It was a hazy
day while the clicking the above images so the details may appear to be a
bit washed out.
Low light shooting is the biggest drawback of the SF1’s camera. The
images way too noisy and you can notice this even without zooming half
way into the image. There is plenty of chroma noise upon closer
inspection and this results in low-light images that are almost
In short, the camera is good only for daylight images, so whatever
your shoot in low-light better be close to the camera; close enough for
both the front and rear flash to cover. The 5MP unit on the other hand
did a great job in normal brightly lit scenarios and yes, the
front-facing LED flash does help. Video recording at 1080p was pretty
much spot-on and this can be said for both artificial and brightly light


The phone is placed at about N50,000 on SLOT. However when it launches fully into the market there may be changes in the price.

Huawei Ban In The US – The Domino Effect And What Is Really Going On



Huawei Ban In The US - The Domino Effect And What Is Really Going On 12

I’ve been following up the Huawei ban by the Donald Trump and administration and to be frank with you, I really hope this ban is reversed because the effect is something I would call a “Domino Effect”. Can you just picture a pack of dominoes falling ?

Huawei ban

I believe you get the picture now, that’s what Donald Trump just set off and I really hope this doesn’t escalate. The US got into a trade war with China and The Huawei ban was a result of the crossfire. This move is affecting a lot of companies not just Huawei and it would slow down a lot of improvements in the tech sector globally.

 Huawei Ban In The US - The Domino Effect And What Is Really Going On 13

Huawei is the second largest smartphone company in the world coming in right below Samsung and just above Apple. They even made an excess profit of $100b some time ago and this money comes in from their various buinesses. Huawei happens to be the biggest Chinese brand in this position globally and it’s really disappointing that this is coming just right after the Samsung Fold issue and people were looking towards the Huawei Mate X as the next foldable device to look forward to , even Android Q now natively supports foldable phones but now it’s seeming like we all will have to wait for another foldable phone to get us excited again.

What Huawei Has To Do With The Trade War

Huawei doesn’t make just smartphones, they make a lot of things from laptops to servers to telecom materials and now they have developed 5G.

Huawei Ban In The US - The Domino Effect And What Is Really Going On 14

Yes you read that first line well, Huawei has developed 5G and is working on improving data download speeds and also fixing the problems that come with such speeds . 5G is not just advanced 4G LTE as many people feel, 5G is actually a whole lot faster. You can download a 2 hour movie on 5G within 3.6 seconds.

Huawei Ban In The US - The Domino Effect And What Is Really Going On 15

Yes.. it’s that fast and with the growing number of driver-less cars , smart homes and inter connected devices, 5G would actually make life a whole lot easier. Doctors can even perform surgeries in a location from an entirely different part of the world. The benefits are just too numerous.

The US was actually the first to develop 4G and it added about $100b to their GDP and created over a million jobs. If they had pioneered 5G first, they would have added $500b to their GDP and created almost 10 times the amount of jobs they created. I get the fact that Trump is a businessman but there are better ways to do settle this rather than accusing Huawei of being a pawn of the Chinese Government.

 Currently, Donald Trump is literally like a frustrated driver in Lagos Traffic getting annoyed that someone overtook him in traffic after he did the same a few moments ago .The major issue Trump is using to cover up here is that he fears that the Chinese Government would use the 5G network to spy on other countries and personally I feel this is just a bit overblown.

The Effects OF 5G and Why The West Is Scared

Now most of our communication systems already have some sort of encryption in place so I really feel it’s not something that we should be worried about . The only major concern here is the power it comes with and the security concerns have gotten into the UK. The UK already set up a panel to investigate Huawei and make sure there isn’t any security  breach or backdoors in the system.

Huawei Ban In The US - The Domino Effect And What Is Really Going On 16

Like it or not, the future of warfare would be totally cyberwarfare, if someone can shut down the communication systems of a country with the touch of a button, the resultant effects would be definitely catastrophic.

I believe you now understand why western governments are scared. I also understand this but I still feel the decision to ban Huawei was rather too hasty even though one Huawei executive was arrested sometime ago for a case related to espionage but I still feel it isn’t enough to pin Huawei completely and start a Huawei ban

Huawei CEO Responds To The Huawei Ban

I followed up an interview where the Huawei CEO was asked to give his views on the Huawei ban is facing at the moment and here’s what he had to say –

Huawei Ban In The US - The Domino Effect And What Is Really Going On 17

“I’m very grateful to the US companies, they’ve grown with us for the past 30 years and made a lot of selfless contributions, they taught us how to walk. Most of my consulting enterprises are in the US for example IBM and many others, Secondly we have received great support from these companies and it reflects
the conscience of the US Firms in this crisis”

“2 or 3 days ago I received a call saying that the US companies are working to solve the crisis by reaching out
to the US Government regarding the ban on Huawei. There a re 4 types of regulations. We are not seasonal control, we received entity control this means whatever US companies are selling to Chinese Companies need to get permission. ”

“Even though the entity control is there the inside of the company would not be affected.
The US is a country with an adequate legal system so US Companies have to abide by the law and so does the entity list. So this affects both US companies as well.”

“We are not quite prepared for our low-end products because we think they will die out soon so those might be affected but our high end products won’t be affected at least 5G won’t be affected. Other companies won’t be able to catch up with us in the next 2-3 years”

“If Google cuts off the support to Huawei it would affect Huawei significantly even though Google is still a good company and we’re working on it to find a solution as soon as possible.”

How The Huawei Ban Would Affect Huawei

Now this ban would actually affect Huawei in two major ways and unfortunately these are the major parts of their company as a tech company – The software part and the hardware part.

Huawei Ban In The US - The Domino Effect And What Is Really Going On 18

The Huawei Ban Software Problem

Google has already revoked their Android License so Huawei can’t use any of their products on future devices. No Gmail, Youtube, Playstore and others. Now these apps are already part of a core Android users mobile experience and you can hardly find a good replacement for that apart from users within China who don’t depend on it.

Huawei Ban In The US - The Domino Effect And What Is Really Going On 19

So basically that on it’s own poses a major challenge for the mobile division of Huawei. Although Huawei has two options in this part to use AOSP (Android Open Source Project) without Google Services or simply create their own OS.

Huawei has already been rumored to be working on their own OS for smartphones , HongMeng OS and according to one of their executives the OS was supposed to be launched this year. If you can recall one of the Huawei GT smartwatches didn’t run on Android Wear but was still a great smartwatch.

Was that actually HongMeng OS?

Well I can’t say for sure but I have a feeling it might be.

In the PC division, there’s the Windows issue, Huawei makes Matebooks which all run on windows. Windows is a Microsoft Product (A US company). So Huawei would still have to chose an OS for their new laptops as well.

The Huawei Ban Hardware Problem

Although Huawei probably has the ability to make a few of the hardware they buy from other companies, if not all but it would still affect them badly. Corning, Intel, Nvidia, Synaptics and Snapdragon are all US Companies and they can’t do business with Huawei immediately after the 90 day period when the ban goes into the effect .

Huawei Ban In The US - The Domino Effect And What Is Really Going On 20

These companies all contribute to Huawei’s products in one way or the other. Huawei has confirmed that they have 3 Months worth of supply stored in their company from each company they buy from, which means Huawei actually prepared ahead of time.

Huawei Ban In The US - The Domino Effect And What Is Really Going On 21

I was confident Huawei would be able to make their own chipsets for their smartphones since they already made it -the Kirin Chipset. Now ARM, a UK based company that makes the components for most of the smartphone processors have also pulled out of supporting Huawei because their production plants are based in Houston Texas. So this still poses a major threat to the development of Kirin Processors.

What lies Ahead for Huawei – HongMeng OS  Or AOSP ?

Huawei Ban In The US - The Domino Effect And What Is Really Going On 22

Huawei as basically two options, to use AOSP without Google apps or use a brand new OS – HongMeng OS that is said to make Android apps 60% faster . Hauwei is a big company and has the capability of making the OS a major competitor in the tech market and with so many restrictions  at the moment the future seems to point towards HongMeng Os and even though I want the restrictions to be removed , I can’t wait to see the new OS.

Infinix Smart 3 Plus Launched In Nigeria – Full Specifications



Infinix Smart 3 Plus Launched In Nigeria - Full Specifications 23

The Infinix Smart 3 Plus is a new device launched by Infinix Mobile and it comes with decent specifications. It’s a device I would say is a mid-range budget device so don’t expect much power from this phone.


I still feel with Xiaomi around in Nigeria now Infinix would have stepped up their game but it seems they’re just recycling designs ever since they released the first device with a tear drop notch.

Infinix Smart 3 Plus Features

The triple rear camera is quite interesting as well.  In terms of design you get a plastic unibody with glass-finish at the back. The glass-finish adds a premium finish to the phone but unfortunately makes it a fingerprint magnet.

Infinix Smart 3 Plus Launched In Nigeria - Full Specifications 24

There’s also a microUSB port, the 3.5mm headphone jack and a microphone just right below the device. The front of the phone shows the teardrop notch, the selfie camera and the earpiece. Sound quality is not that bad however, The Smart 3 Plus has a downward firing mono speaker which isn’t too loud and you’ll actually prefer using your headphones. I still wonder why Infinix didn’t use the Dirac Speakers in this device.

Infinix Smart 3 Plus Launched In Nigeria - Full Specifications 25

It has a HD+ resolution display with a 2.5D glass for a premium feel. But I’m a bit disappointed with the 720p resolution and the large display doesn’t actually show what we all expected. It’s a bit low but I’m guessing it’s a sacrifice to put the phone in the budget range.

The back of the phone houses the triple-camera setup .The primary sensor is a 13-megapixel camera with a 2-megapixel depth sensor and a low-light QVGA sensor.

Let’s take a look at the quick specifications of the device
