Ntel phones are better of than Nokia. Their Nova brands are superb. I didn't say Itel. Read again.

You said what

Over the years in Nigeria, Samsung has been one of those brands that build devices for premium users. Their flagship devices in the S series and Note series are highly rated among users in the Nigerian Android community. Considering the specifications their flagship smartphones come with, I wouldn't actually blame them for putting the devices at price range they usually sell it.



This year Samsung released about 5-6 premium devices - Samsung Galaxy S 10, Samsung Galaxy S 10 Plus, Samsung Galaxy S10e (This is the smallest and cheapest version of the Samsung Galaxy Series), Samsung Galaxy S10 5G (The 5G variant of the S Series devices), Samsung Galaxy Note 10 and the Samsung Galaxy Note 10 Plus.

All these devices cost between N100,000- N350,000 depending on the variant you choose to buy. If Samsung had decided to stick with the usual yearly line up they would still make money, they're a big company and it's quite easy for them to make huge sales. However, Samsung decided to enter the mid-range smartphone segment that has been dominated by the Transsion boys for a while (By Transsion boys - I mean Tecno, Infinix and Itel) . This move has disrupted the market massively.



Transsion Holdings business model is quite easy to notice if you are very observant - Itel devices handle the entry-level smartphones for the lower class of the economy, while Tecno and Infinix build devices for the middle class.

The purchasing power of the middle-class all together trumps the ones of both the elites and low-class part of the economy, giving Transsion a lot of customers to push their products to and the business model worked extremely well for them till Samsung, Xiaomi and Nokia came into the picture.

Samsung, Xiaomi and Nokia are dragging the community away from Tecno and Infinix because of two main reasons

1.Tecno and Infinix suck at sending updates : There's nothing customers love more than constant updates, even if it's not a full OS upgrade, minor software updates gives users a very subtle impression that the brand still knows their device exists and is working to improve it. The Transsion boys really suck at this.



2.Tecno and Infinix aren't totally innovative: When it comes to design aesthetics you would agree with me that there hasn't been any mind-blowing design from these two brands. All they do is take cues from other brands and add minor design changes.

The difference between the brands are quite obvious. I know you're judging me for comparing the transsion boys to global brands but I believe they can do better. For example only the Tecno Spark 3 Pro was confirmed to receive Android 10 and it's still in beta - You can access that on Tecno's page by googling "Tecno Spark 3 Pro Android Q beta program". That's one device out of over 20 other recent ones out there they confirmed is getting the update and like I always say -That sucks.



Samsung on the other hand is taking advantage of the fact that they are more popular to stay ahead of Xiaomi and Nokia. I was talking to a friend about this some days ago and he made some very interesting points.

1.Most people are skeptical of using Xiaomi because of the "Chinko" factor

2.Nokia on the other hand just came back to the market after their failed partnership with Microsoft and only extreme loyalists would go back to them. However, Nokia would sell more in Nigeria than Xiaomi because of their previous reputation.

On my own part I feel the "Chinko" factor is a misconception. Xiaomi devices are awesome, the Android OS running on MIUI is amazing and it's one of the best I've seen so far. However, Xiaomi would have to battle that while Samsung would be on a cruise in the market.

Samsung's A Series is their response to the mid-range segment and boy are they working wonders. The smallest device in the lineup the Galaxy A10 has 2GB RAM , an Exynos Processor and 32GB of internal storage and the device costs less than N40,000.



Samsung has literally a device on every price range from 36,000 - 120,000 naira. Here's a list of devices on their lineup.

Samsung Galaxy A10 & A10s

Samsung Galaxy A20 & A20s

Samsung Galaxy A30 & A30s

Samsung Galaxy A50 & A50s

Samsung Galaxy A70 & A70s

Samsung Galaxy A80

Samsung Galaxy A90

Samsung released 12 phones covering literally every reasonable price range in a space of one year and the phones have been a hit. I use a Samsung device and I've received updates more than 4 times in less than 4 months.

Updates lets users enjoy their phones for as long as they want and only upgrade when they want to, Transsion's business model of refusing to push constant updates so customers would buy new phones isn't acceptable and if care isn't taken, they'll lose a lot of customers to Samsung and the new boys in the Nigerian smartphone market.

Like my friend says

Nonsense write up

If others can do it even south Africa, why cant we?

Before 2022..we I'll be already on 5g and nothing your negative mindset can do about it

There is no AFRICAN COUNTRY with functional 5G at the moment

5G technology. Everyone is hyped up about 5G technology and the crazy data speeds it would come with, even the NCC Nigerian Communications Commission (NCC) approved tests for the 5G spectrum in Nigeria but the question is this – Is Nigeria Ready For 5G technology





I know all the paid marketing platforms has been heating up considerably over the past few weeks, pushing out different spectacular theories on how 5G is going to change the way we work, live, and copulate.(Again, at least one of those items is my own nonsensical creation, but I’d argue that all of them are equally absurd.)

I’ll tell you this, you can safely ignore all these regardless of who or what is saying anything about it. So as an ardent lover of tech. I strongly advise you observe from a distance with a hot cup of cappuccino and box of chocolates for now without investing an ounce of your own money or mobile tech energy in the effort.


Let’s get to the reasons


5G Technology Is A Short Range Network Spectrum And Very Limited



If you remember clearly 4G only started functioning in Nigeria around 2015-2016 when it was available in other parts of the world for years. It was like a dream come true before it dawned on us that we have one of the slowest 4G speeds in the world. Globacom even had to put their bandwidth on one that isn’t available on most devices to make sure their 4G doesn’t slow down as much as their 2G masked as 3G.

No matter how much our network providers might hype it, 5G is going to be extraordinarily limited in real-world application in Nigeria right now in 2019 unless it’s limitations are actually fixed before launch in Nigeria

Unlike 4G that signals can be received from over 30 miles, 5G cannot go more than a mile and if you’re in a building it’s very likely the speeds would drop drastically. For 5G to work in Nigeria their needs to be multiple network towers and the only logical way to have that is to fix them on electricity poles just like Verizon is doing in the United States but this is Nigeria, there’s an adept lack of maintenance culture.

I can’t count the number of things that could go horribly wrong here if those towers are mounted on electric poles, be my guest and help out with a list.



Also the nature of these new 5G towers is raising fresh concerns over cancer risks, We don’t have a functional health care system here. So until there’s assurance from network providers and it is verified that it’s safe for use, those towers shouldn’t be mounted 3m close to anybody’s house



5G Network is Horribly Expensive

You know how data finishes extremely quickly on 4G especially on MTN, on 5G you can finish your data bundle within 30 seconds, ignoring all the limitations.



Network providers are willing to do anything to make more money, who wouldn’t anyway… 5G technology just happens to be a perfect way to charge customers more money something I know won’t go down well with many Nigerians.

The phones that support 5G don’t come cheap either. Samsung’s 5G S10 variant costs almost $1000. Keeping 5G services a premium service that’s not going to be available for everyone unless we end up getting affordable phones from brands like Xiaomi that support 5G.



Possible Lack Of Cross Carrier Compatibility

I’m talking about this with information based on countries that already have 5G being tested. Now unlike 3G or 4G that have bands supported by a wide range of smartphones. 5G isn’t going to give us that luxury. We know our network providers go mad once in a while and we can easily switch to another SIM easily but 5G might just make us change that. Carriers in the United States are adopting their own personal 5G standards and I believe other networks in the world might do the same.

Unless there’s a certain 5G standard each network provider here would use. You would end up stuck with a device that supports only one network’s 5G band.

shame !!! you basically copy everything word to word

Word to word indeed. I wrote this post like 2 days after watching this video and a couple of other videos so please kindly explain how this is the same as what dave2d said. I might have used similar examples but the post is different. Like I mentioned this is not a transcript

kingxsamz:
Most android phones look alike. And so? wetin dem wan resemble before.
Mr man, the difference is in the taste.

Taste in what part?

yusfatedeeprof:
How i feel you copied this from a YouTuber "dave2d"

You basically typed out everything he said in his video, talking about pixel 3a

Lol. I wish but this clearly isn't a transcript. Might be similar but definitely not the same. I watch a lot of tech videos so I can't say if there's any similarity to the particular dave2d video you're referring to

In this post I’ll be looking at a something that has been bothering me for a while – How Android Smartphones Are Slowly Turning Into Commodities.

Starting from the end of 2016 till date Android smartphone design aesthetics have moved from being a bit bulky to being almost bezelless.



I appreciate that fact but every good thing comes with a little bad side and unfortunately the bad side of this issue might actually wreck the entire Android ecosystem if companies don’t come up with good enough designs to make people see reasons to actually get a new smartphone.

If you’re wondering what I mean by Android smartphones becoming commodities, well take a close look at this image below.



Can you tell the difference?




Forget about the specs for a while and take a closer look. You know how we all see printers like mere products with different prices, we would see smartphones that way soon. Apart from that the user experience on every Android smartphone is very similar so it’s still basically the same product built on different hardware with an identical design. Doesn’t that remind you of a digital printer or any other computer peripheral?



Even smartphone companies are aware of this hard truth, they want us to buy new phones but with everything in their lineup looking the same it’s harder to sell new flagship device.

So far only Huawei and Vivo aren’t experiencing problems in selling their flagship devices, the rest of the companies , Apple , Google and Samsung are finding it hard to sell their new smartphones and they are responding to this in different ways.



Google announced the Pixel 3A a few days ago, a smaller version of the Pixel 3 , Samsung and Apple have reduced the price of some of their devices (Apple’s price cut only affected China).

Sometime ago, Apple even had to reduce the speed for their older iPhones just to sell the newer ones.

I still give Samsung and Huawei a thumbs up for pulling off the design on the foldable smartphone. However they’re both still very expensive and not something average users would want to spend money on. Irrespective of the mishap that happened on the Galaxy Fold , I still think we can look towards foldable phones to bail the Android OS out. Hopefuly the next version of the Galaxy Fold won’t be a complete mishap.

Apple might actually survive the whole issue since they have total control over their OS, Android on other hand might not. Android Manufacturers should look beyond specs and give us something that would give us reasons to actually get a new phone apart from specs.

Credits to Oppo and Vivo that are pulling ahead in terms of smartphone innovation, coming up with new designs that are usually copied by other brands. The Samsung A80 for example still uses the pop up camera module but in a different way. So users basicaly get a camera that can flip.

Oppo is also planning to launch a phone with the camera beneath the screen this year as well. It seems Android brands need to take a cue from Oppo and Vivo if they want to keep selling their products

In this post I’m going to be looking at the Top 10 Smartphones With The Best Camera globally at the moment. These rankings are based on their DXOMARK scores. Before we go into that I sincerely apologize for going MIA. I have a lot going on in school at the moment, Uniport is pretty stressful.



That said let’s get into what this post is about. Smartphone cameras have been improving over the years and this year smart phone brands are really pushing their phones to the limit and in a couple of years we might have no need for the DSLR Camera as we know it but who really is the king of smartphone cameras?

Let’s find out.

Top 10 Smartphones With The Best Camera In The World

9. Samsung Galaxy Note 9

The Samsung Galaxy Note 9 comes in 9th on the list of Smartphones With The Best Camera In The World with a DXOMARK score of 103. The Note 9 comes with a dual-camera setup, featuring a wide-angle camera with 12MP sensor, f/1.5-2.4 dual-aperture lens, and dual-pixel autofocus. The second camera offers a 12MP sensor with a 2x “telephoto” lens and f/2.4 aperture. Both lenses are optically stabilized.



Besides being equipped with dual cameras, the Note 9 features AI-assisted camera operation, with the company calling it their most intelligent camera yet. For example, the system can identify key elements in an image and optimize shooting settings and image processing based on one of 20 separate categories.

Video enthusiasts can capture 4K footage at 30/60fps. Other high-end features include a large 6.4-inch Super AMOLED (2960×1440) display, AKG-tuned speakers, and depending on region, a Qualcomm Snapdragon 845 or an Exynos 9810 Octa chipset.

Key camera specifications:

Dual cameras
Primary: 12MP (1/2.55-inch sensor, dual-pixel PDAF, f/1.5-2.4 variable-aperture lens)
Secondary: 12 MP (f/2.4 lens, 1/3.6-inch sensor, AF)
OIS on both cameras
Single LED flash
4K video at 30/60 fps


8. HTC U12 Plus

HTC might be struggling in the mobile sector but they managed to give us one of the best smartphone cameras so far. Coming in 8th in the list of Smartphones With The Best Camera In The World is the HTC U12+ with a DXOMARK score of 103.



HTC U12+ comes with a 12Mp sensor and wide-angle (27mm-equivalent) f/1.75 lens with OIS for the primary camera, together with a secondary 16Mp sensor and telephoto (54mm-equivalent) f/2.6 lens for 2x optical zoom. Running Qualcomm’s latest Snapdragon 845 chipset, there’s plenty of power for imaging tasks, along with a “Pro” photography mode for greater manual control and RAW-format file support.

HTC’s Ultraspeed Autofocus 2 system offers phase detection and laser-assisted autofocus; there’s a bokeh simulation mode for artificially blurring the background in portraits; and a dual-tone LED flash unit. For video enthusiasts, the HTC U12+ can capture movies at 4K resolution up to 60fps.

Key camera specifications

Dual camera setup
12Mp main camera with 1/2.55″ sensor (1.4µm pixel size), f/1.75 lens and OIS
16Mp secondary camera (1.0µm pixel size) with f/2.6 2x telephoto lens
Phase detection and laser-assisted autofocus
Dual-LED flash
4K video at 60fps

7. Apple iPhone XS Max

Seven they say, is a lucky number and it’s not really surprising to see the Apple iPhone Xs Max comes in 7th in the list of Smartphones With The Best Camera In The World with a DXOMARK score of 105.



Although the camera specs on the surface look pretty much identical to the iPhone X. A closer look reveals important changes. For example, the 12MP sensor in the dual-camera setup’s wide-angle module is now larger than before, featuring 1.4 µm pixels compared to 1.22 µm on the iPhone X. But like the previous version, the new lens channels light onto the sensor through a 6-element lens with an f/1.8 aperture, and as before, the 2x tele-camera comes with 1.0µm pixels and an f/2.4 aperture in a six-element lens. Both lenses are optically stabilized.



On the software and image processing side of things, the improvements are more obvious. During still image capture, the camera continuously captures a multi-frame buffer at different exposures, allowing for simultaneous zero shutter lag and HDR processing, something that is unique to the new iPhone at this point. This also means the iPhone XS Max is capable of displaying HDR images in real-time in the preview image, so what you see is what you get.

In video mode, the iPhone XS Max can shoot 4K video at 60 frames per second and 1080p Full-HD at up to 240fps. The faster sensor readout allows for better video stabilization and a reduced jello effect. In addition, the camera can shoot footage with expanded dynamic range when the frame rate is limited to 30 fps

Key camera specifications:

Dual-camera setup
12Mp main camera with 1/2.55″ sensor (1.4µm pixels) and six-element f/1.8-aperture lens, 26mm equivalent focal length
12Mp secondary 2x tele-camera with 1/3.4″ sensor (1.0µm pixels) and six-element f/2.4-aperture lens, 52mm equivalent focal length

6. Xiaomi Mi 9

The Xiaomi Mi 9 holds the sixth spot in the list of Smartphones With The Best Camera In The World with a DXOMARK score of 107. This is Xiaomi;s first device with a triple-camera setup. The main module captures image information on a 1/2″ 48Mp sensor that produces 12Mp output images. In addition, there’s a 12Mp 2x tele-module for zoom shots and a 16Mp super-wide-angle with a 117-degree field of view. The autofocus system uses a mix of PDAF, laser, and contrast detection.



Users can view, edit, and compose images on an AMOLED display with Full HD+ resolution, and the device is powered by Qualcomm’s latest top-end Snapdragon 855 chipset.

Telephoto: 12Mp sensor with 1.0µm pixels and 52mm-equivalent, f/2.4 aperture lens, PDAF, OIS
2160p/60fps (1080p/30fps at default settings)

4. Huawei P20 Pro

The Hauwei P20 Pro takes the 4th place in the list of Smartphones With The Best Camera In The World with a DXOMARK score of 109.The P20 Pro is the first smartphone to feature a triple camera setup. However, Huawei hasn’t simply slapped a third sensor and lens onto its current dual-camera system. The new model stands out among its peers in several ways:



At 1/1.78″, the main camera’s sensor is unusually large—approximately twice the size of the Samsung Galaxy S9’s 1/2.55″ chip. Despite a slightly slower f/1.8-aperture lens, the RGB main camera sensor of the P20 Pro captures approximately 20 percent more light than the smaller sensors used in most competing models. As with previous high-end Huawei smartphones, the main sensor is supported by a secondary monochrome sensor which helps further increase photon capture.

The main camera sensor uses a Quad Bayer structure with a total pixel count of 40Mp. It outputs data binned in 2 × 2 pixel units, resulting in 10Mp image output.With an equivalent focal length of 80mm, the P20 Pro’s optically-stabilized tele-camera offers a significantly longer reach than the 2x tele-modules in the latest iPhone or Samsung Galaxy devices.



This is possible because the main camera in combination with the 20Mp monochrome secondary sensor is already capable of delivering decent zoom detail at a 2x zoom factor. As a consequence, the engineers have been able to focus on squeezing a longer reach out of the P20 Pro’s tele-lens. The Tele also outputs 10Mp image.

The monochrome sensor in the camera setup serves several purposes: it helps with depth estimation for the simulated bokeh effect, and the fine detail and low noise levels of the monochrome sensor improve image quality when zooming and in low light.

Key camera specifications:

Triple camera setup
Main camera: 40Mp, 1/1.73″ RGB sensor with Quad Bayer structure, f/1.8-aperture lens with 27mm equivalent focal length
Secondary camera: 20Mp, 1/2.78″ monochrome sensor, f/1.6-aperture lens with 27mm equivalent focal length
Tele-camera: 8Mp, 1/4.4″ RGB sensor, f/2.4-aperture lens with 80mm equivalent focal length, and optical image stabilization
Aperture mode default eq. focal length: 55mm
PDAF on main sensor
4K video (not default mode)
960 fps slow-motion video at 720p
6.1″ display, 2240 x 1080 resolution
Kirin 970 chipset


3. Huawei Mate 20 Pro

The Huawei Mate 20 Pro takes the 3rd place in the list of Smartphones With The Best Camera In The World with a DXOMARK Score of 109. Building on the P20 Pro’s camera technology, the Mate 20 Pro comes with a Leica-branded triple-camera setup, but swaps its stable-mate’s monochrome camera for a super-wide-angle module, offering a 35mm-equivalent focal length range from 16 to 80mm—the widest of all current smartphone cameras.



Other components housed in the IP68-rated glass and metal body are all worthy of a premium device as well. Processing and other tasks are powered by Huawei’s new Kirin 980 chipset, and users can compose and view images on a large 6.39-inch HDR OLED display with 1440 x 3120 pixel resolution.

Key camera specifications

Triple camera
40Mp main camera with 1/1.7″ sensor; f/1.8-aperture, 27mm-equivalent lens
20Mp super-wide-angle with f/2.2-aperture, 16mm-equivalent lens
8MP tele with f/2.4 aperture, OIS, 80mm-equivalent lens
PDAF + laser AF
Dual-tone LED flash
4K video at 30fps (1080p/30fps at default settings)


2. Samsung Galaxy S10 5G

The 5G variant of the Galaxy S10 comes in second in the list of Smartphones With The Best Camera In The World with a DXOMARK score of 112. It comes with 8GB of RAM, along with a 6.7-inch, 3040×1440 pixel, HDR10+ -certified AMOLED display. It’s loaded with either 256GB or 512GB of memory, which is helpful, since there is no microSD slot.



The main camera system combines a primary 12Mp camera and variable-aperture lens with a 16Mp ultra-wide-angle module and a 12Mp 2x telephoto module. Compared to the standard S10 model, the 5G model also adds a Time of Flight (TOF) sensor to assist with bokeh when shooting video as well as with augmented reality applications.

Key camera specifications:

Quad-camera setup, including a dedicated TOF sensor
Primary: 12Mp sensor with 1.4µm pixels and 26mm-equivalent, f/1.5–2.4 aperture lens, dual-pixel AF, OIS
Ultra-wide: 16Mp sensor 1.0µm pixels and 13mm-equivalent, f/2.2-aperture lens
Telephoto: 12Mp sensor with 1.0µm pixels and 52mm-equivalent, f/2.4 aperture lens, PDAF, OIS
2160p/60fps, shoots 4K video at 30fps by default


1.Huawei P30 Pro

The Huawei P30 takes the throne as the King of Smartphone Cameras at the moment with a DXOMARK scroe of 112 .



The P30 pro comes with a triple-camera setup (quad-camera, if you count the time-of-flight sensor) that offers a plethora of improvements over both the P20 Pro and the Mate 20 Pro (launched in October 2018).

The primary camera comes with a 1/1.7 40Mp quad sensor that produces 10Mp image output. The 27mm-equivalent lens comes with an f/1.6 aperture and is optically stabilized—a first for this sensor size in a smartphone. Thanks to a minimum focus distance of 25mm, the 20Mp super-wide-angle (16mm-equivalent) camera is capable of capturing macro shots, but the arguably most exciting innovation is the stabilized tele-camera that uses folded optics to achieve a 5x optical zoom factor (125mm equivalent).

5x optical zoom with folded optics

The laws of physics make it difficult to fit a longer zoom lens into a thin smartphone body. Even using smaller-than-usual image sensors and clever lens design, manufacturers have only managed so far to achieve 2 or 3x optical zoom factors in conventional high-end smartphones.

For the P30 Pro, Huawei uses folded optics to overcome this limitation. The image sensor is placed vertically within the phone and aimed at a lens with an optical axis that runs along the body of the phone, and a mirror is used to reflect incoming light into the lens and onto the sensor. This allows for a much longer equivalent focal length than would be possible with a camera oriented in the usual fashion—that is, one constrained by the phone’s thickness.

Field-of-view fusion zoom

The P30 Pro doesn’t rely just on hardware alone for zooming, however. Software is just as important, and the P30 Pro uses a system Huawei calls field-of-view fusion, a combination of optical and algorithm-powered digital zooming that adapts to the chosen magnification factor. Up to 3x magnification, the tele-lens remains unused; instead, the camera performs all zooming with the help of a super-resolution algorithm—a concept similar to what we saw on the Google Pixel 3, one in which the camera merges several RAW frames into one high-resolution frame that it then crops for zooming.

Key camera specifications:

Triple-camera setup
Primary: 40Mp, 1/1.7-inch quad RYYB sensor; f/1.6-aperture lens, OIS, 27mm-equivalent focal length
Tele: 8Mp sensor, folded optics with f/3.4 aperture lens, OIS, 125mm-equivalent focal length
20Mp super-wide-angle with f/2.2-aperture, 16mm-equivalent lens
PDAF/Time-of-flight (ToF) autofocus
LED flash

So there you have it the TOP 10 list of Smartphones With The Best Camera In The World. I still wonder why the Google Pixel 3 Didn’t make the cut. Well, keep an eye on this page for updates.

In this post I’ll be showing you how to make your data subscription last longer We all dread getting that notification from our ISP or telco that our data subscription is about to finish and it can be annoying and really disappointing.



Although, I’m pretty sure we can always blame our ISP’s for coming up with different data zapping techniques, especially MTN. Nevertheless here’s a way to keep your data from running out too quickly.

There are 2 ways to do this – Turn off background data or set a data limit within your social media apps.

How To Turn Off Background Data

2019 is the year of multiple cameras and many if not all smartphone brands have released phones with multiple cameras. You’ve probably seen the Nokia 9 Pureview with 5 cameras and the Huawei P30 Pro that comes with 4 cameras (40MP + 20MP +12MP +TOF Camera) and 50x optical zoom.



Huawei P30 Pro



Nokia 9 Pureview

These two devices come with crazy specifications but I won’t go into that right now, maybe in another post. However, have you ever tried covering the main camera of your device with a dual camera? If you haven’t, try doing that right now.

You’ll notice you are actually blocking the whole camera. That leaves the question – What do the secondary cameras do and how do they work.




How Multiple Cameras Work

Now I want you to understand this. Most OEMs have other uses of their secondary camera other than the ones I’m going to mention below. These are just the basic functions of the secondary camera.

The secondary camera improves the overall clarity of the image with the help of a “Monochrome” feature. The secondary camera only records the black and white version of the image. With the help of the Monochrome sensor, the primary camera measures how much light is coming from the point of focus.

Previously (with the exception of the Google Pixel 3), the primary camera in smartphones normally handled the measurement so there was a very high possibility of losing some detail while measuring light intensity since it would still need to work on the color filtering.

So this extra burden is handled by the second camera which takes care of that area. Combining the monochrome image which has detailed information about the light and sharpness with the colored image that was captured by the primary camera will produce a rich and detailed image.

In some phones, the secondary camera acts as the zoom lens. Huawei uses their cameras on the P30 Pro a bit differently but going into the entire details might end up making this post a bit lengthy and a bit boring for people who aren’t hardcore techies so I’d try to keep this balanced. However, if you’d like to see that in another post do let me know in the comments.

So that’s basically how multiple cameras work on smartphones

The official whatsapp app leaks data of it's users as well.. so what are they saying?

They should stop been hypocritical jere.

How?.. I'm pretty sure you have the right to sue whatsapp if your data is leaked but if someone using a 3rd party app has his data leaked do you think Whatsapp would care. The only thing is that the news headlines would say its whatsapp data that was leaked. Which brand would want that

I can remember making a post about the dangers of using clone apps like GB Whatsapp and the rest now Whatsapp has released an official statement concerning users of these apps and you will have no Alternative but to switch to the regular app or else.



Using third-party Whatsapp applications like GB Whatsapp has become quite popular because of the features they offer. For example, you can disable the blue tick/secondary tick and even hide the fact that you are viewing other people’s Whatsapp stories, giving you the ability to stay anonymous on Whatsapp.



However, the dangers they pose are often ignored by a lot. For example, these platforms could secretly store your data and that doesn’t even cover everything!

WhatsApp has issued a warning against the continued use of clone apps like WhatsApp Plus and GB WhatsApp, citing security concerns as the primary reason. The Facebook-owned app will ban user accounts created in those clone platforms.

According to new reports, Whatsapp is set to ban accounts of users who have been using these third-party platforms.

Even though this is a temporary ban, Whatsapp didn’t specify how long the ban is going to last. However, reports claim that users would be advised to switch back to the supported Whatsapp version to lift the ban.

According to Whatsapp:

“If you received an in-app message stating your account is ‘Temporarily banned’ this means that you’re likely using an unsupported version of WhatsApp instead of the official app. You must download the official app to continue using WhatsApp.”

Can you make a comparison between a country's mobile data cost and average income?

I.e. Percentage of income used for say 1GB, 10GB, 100GB.

Use this thread for average monthly income: https://www.nairaland.com/3835124/average-salary-monthly-wages-around#57103053

Sure.. Will do

Normally when it comes to cheap data plans I always tell people that Nigeria is one of the countries with the cheapest data plans in the world and I haven’t been too far from the truth. Take a look at at this graph from Statista.




Nigeria ranks 4th in the list of selected countries with the cheapest data plans.

While a gigabyte of data would set Italian smartphone users back $1.73, the same amount would cost $2.22 in Nigeria, $2.99 in France, $6.66 in the United Kingdom and $6.96 in Germany. Costs are even higher in North America where they average $12.02 in Canada and $12.38 in the United States.

So should we give our Network Providers some accolades for giving us the cheapest data plans in the world?




Nope. Definitely not worth a standing ovation especially if you check the fact that we have one of the slowest 4G speeds in the world.




Nigeria’s top 4G speed is placed between 9.5Mbps and 16.2Mbps, while Algeria’s slowest speed of 2.6Mbps is the worst in the world.

However here’s the plot twist, the country with the slowest 4G speed – Algeria’s top download speed of 16.4Mbps still beat the fastest speeds in Thailand (11.7Mbps), India (14.6Mbps) and Nigeria (16.2Mbps).

Now I feel they only deserve the accolades for constantly zapping our data. Nevertheless I feel ISP’s in Nigeria can definitely do better than this.
