If you're an active mobile phone user, you will notice that your phone can actually make emergency calls without any SIM. I know you must be wondering how this is possible since there's no mobile number. Let me explain how your SIM works. SIM as you ought to know stands for Subscriber Identification Module and it helps to identify the cell service subscriber that is trying to connect to the network. Every user has their own SIM, so network providers can direct calls to that specific phone and track usage (and charges) individually. The identifying number of a SIM card is called an ICCID.

The IMEI is like the DNA of a phone; all phones can be identified just with their IMEI. This is a logical example of what happens when you call your friend with a SIM card:
Michael’s phone to cell tower : My IMEI is 123 and my ICCID is 456. I want to call +234-123–456–7890, please!

Cell tower: IMEI is 123, ICCID is 456; 456 is Michael’s account. I’m from Michael’s cell phone carrier and provide him with service, Michael has 100 minutes left in account, connecting call.

Michael : Thanks!



Now This is what happens when you try to call a friend without a SIM card:

Ade’s phone to nearby cell towers: My IMEI is 123 and I don’t have any SIM card. Please let me call +234-123–456–7890, please!

Cell Tower: Who's this one again ? Are you normal? You didn't even subscribe to any services, or even my own network ; why should I give them to you for free? Gerrarahia Mehnn!

Ade : Chai!

That sounds quite interesting, right? In the first instance, the cell tower allowed Michael to place the call because it knew who he was and that he was paying for it, but in the second, Ade was unsuccessful in placing the call because the tower had no idea who it was and didn’t want him using the service for free. It's like allowing a total stranger into your home.

Now what if the person on the other side of the door was involved in a terrible accident , on fire, or getting robbed ? What would the cell tower do?


Musa calling 911 or 112 with SIM card:

Musa’s phone to cell tower: Help Musa is dying! My IMEI is 123, my ICCID is 456, my latest location is 123 Musa’s Place, please connect to emergency services!

Cell tower: I can see Musa’s info with ICCID #456 and your latitude and longitude coordinates, connecting to Emergency Number!

Musa : Help, I’m on fire!

As you can see, 911 was able to receive information about Musa thanks to his ICCID and GPS coordinates.

Rochas calling 911 without a SIM card:

Rochas' phone to all nearby cell towers: Hello, please anybody around , help! Rochas is on fire!

Nearby cell tower: I’ll take the call! I really don’t care who you are, but I’m willing to help! Your IMEI is 123, meaning that you’re a Black variant of the Tecno Phantom 8, and your location is 123 Rochas’ Place! Connecting to Emergency number because I’m nice and I don’t want you to die yet !

Rochas : Help oh ! Rochas still got the help he needed, even with no SIM card. The emergency services would’ve been unable to receive much detailed personal information on John, but they knew his location and would be able to get there quick.


To round it up, cell phone towers are a lot more like paranoid kids staying at home for the first time. They won’t let you in if you don’t know their “secret password” lol, but are kindhearted enough to accept your pleas to help no matter who you are. So next time you’re in an emergency, don’t let “no service” fool you.

A couple of days ago I was using a friend's phone in his living room, a few minutes later someone called me so I dropped the phone and went outside. On my way back to the living room, I heard some funny sounds and I could swear his junior bro (a 14 year old kid) downloaded & was watching p0rn on the phone. I observed his brother from the door for a few minutes before walking in and before I could get to where he was he cleared everything immediately . Of course I asked him what he was doing and he lied that he was watching soccer highlights.I just opened the notification logs to check what he was doing before I came in...and that was actually the 5th video he downloaded.

Notification Logs can come in handy when you or someone clears your previous notification from the notification bar or you can't remember the notifications you missed. Here's How to get access to the notification log



Step 1. First of all, long-press on a home screen of your Android device.

https://i.imgur.com/ImUaytI.jpg

Step 2. Now select widget option there and then swipe to left until you find “Settings” widgets. Tap on it and drop it on your home screen.


Step 3. Now option will appear to set the shortcut of any of settings, scroll down and select “notification log” there.

I just mailed you.

I Trust Nigerians. They'll want to help you do it without explaining what it involves. I'll advice you if it's a blog that's less than 6 months old or without reasonable backlinks you can move but If it's above 6 months and has a number of backlinks just do it carefully. I tried moving to wordpress it affected my SEO badly, thankfully i moved back before things got worse. All the same wordpress is very good and better than blogger if you start your blog with it but get ready to contact your host in case you have issues. If you need a life free of downtime and worries about hosts remain where you are but if you have the cash and time to spend on wordpress you can move.

I've been doing this for a while now and its lucrative and I thought I'd share with you guys.

It's a free info jare

So, I'm just a young girl that started blogging at age 15. I created a serious anonymous blog at march.

I'm a good writer and write awesome contents on my blog.

After 4 months, I still haven't made the type of money I want, just pennies because the only way a blog can earn you good money is the traffic.

And if you don't invest on your blog to get that traffic, you'll get frustrated after some years and quit!

That's why majority of bloggers don't make money yet, no traffic.

I came up with a plan on how to increase my blog traffic, but I needed extra money like N150k to execute it.

After some time, I got an idea and had several thoughts on it.

The idea was, since Im a professional blogger already, and I can design and create any kinda website, what stops me from making a banner, goto the printing press and have them print it to my choice.

I went ahead and organized everything and made the banner, in the morning, I went out in search of a good area where my banner can fit.

I found a busy and good place, the next day, I went out at 8am, and with the help of my brother we placed the banner at a junction, the one I surveyed.

The first person to contact me was a lady whose shop is opposite the banner (across the road) to come and create an e-commerce website for her.

On the banner, it was simple, I listed the kinda websites I specialize, told them the price and my contact details.

So, my dear friends, that was how I started making money, like good money creating these websites for people.

And my pricing starts from N50k and above.

I was able to do the investment on my anonymous blog, and built my blog traffic and starting making money too.

You can create a banner of your own and offer different services too, I know there is something you're good at.

Just give it a try, it works!
(I now have the banner in 3 places).

Nice.. I'm impressed. Keep up the good work. What's your email address

I love naijatechguy. Awesome write up. Facial recognition won't still ace up. Fingerprints in screen is a Wow. Snapdragon chipsets will finally conquer in 2018.

...yeah certainly

lol..note that not all Nigerian blogs are unprofessional. Mine definitely isn't.

and besides only long boring posts are not read.

Generalkorex:
Cool features. Still waiting for the time we will start downloading food from our phones

lol . you can actually. but not from your phone. MacDonalds has a food ATM . it's not yet available in Nigeria though. so I'm imagining hungry Nigerians queuing up to withdraw food .-https://www.eater.com/2017/1/26/14400334/big-mac-atm-mcdonalds

abumeinben:
Cool



Especially these.

What do you mean by "even Xiaomi"?

considering the fact they prefer a highly customized MIUI interface, however a few of their devices actually came with stock Android with very minimal traces of MIUI

Mynd44:
1. No money is petty as long as it is worked for.
2. 15K is not the problem, the thought that you are entitled to anybody's money is just hilarious and an insult to feminism and independence

Mynd44 please could you talk to seun about this spambot..and please unban me as well and my thread. if i try modifying it after being unbanned it may ban me again.

Thanks

2017 came with a lot of improvements in smartphones as we know it. In the smartphone sector, we all witnessed a shift towards full view displays and dual cameras, and other significant evolutionary upgrades for the better.

The performance and battery backup of affordable phones has never been better, thanks to powerful and power-efficient chipsets like Snapdragon 625 and 835 Chipsets. Nevertheless I'll say we still don’t have a perfect Android (or iOS) flagship, but at least we have, what certainly feels like, a perfect camera phone.

Let me quickly recap the major smartphone trends of 2017 before I tell you what I think we should expect in 2018.

1.Full-view displays took the world storm.
2.Dual cameras
3.4GB RAM and 64GB storage are now available on affordable phones.
4.Face Unlock gains some traction.
5.Stock Android is no longer a rarity (Nokia, Billion, Tenor, Moto, HTC, and even Xiaomi).
6.Snapdragon 625 consolidated Qualcomm’s position in affordable and mid-tier phones.
7.In general, battery backup on phones has improved a lot.


So, that brings me to the next question. What’s in store for us next year? Well, there are quite a few interesting upgrades you should expect.

In-display fingerprint sensors

[img]http://3.bp..com/-a7CxCU4va6w/WkS_XyDhNaI/AAAAAAAAAY0/G5Bu8jCBU-s6OpTIbm5avy8lJlUDIJbbQCLcBGAs/s640/under-display-fingerprint-sensor-image.jpg[/img]
Do you know why Samsung's Note 8's fingerprint scanner is an awkward position?, It's because it was actualy meant to be under the screen but Samsung couldn't meet up and had to place it beside the camera. However Vivo have already made a prototype with the Finger Print Scanner under the screen.
The biggest casualty of 18:9 displays have been the front fingerprint sensors. The Face Unlock isn’t as good a replacement which is why manufacturers have been working on under-display fingerprint sensor for a while.

In-display fingerprint sensors have now entered mass production. In fact, the first mainstream in-display fingerprint sensor phone from Vivo is set to arrive as early as CES 2018 (January 09-12).

Snapdragon 660, Snapdragon 630 For Mid-Range Smartphones

[img]http://4.bp..com/-EpZSS5Ur2gE/WkS_ex-30fI/AAAAAAAAAY4/RUTPd3RU_0YlP_kKWLpPoUhlhGotiyf2wCLcBGAs/s1600/oppo-r11s.jpeg[/img]
The success of Snapdragon 625 and Snapdragon 430 helped Qualcomm infiltrate MediaTek’s stronghold last year. To further strengthen its grip, the dominant chipset maker will be pushing a lot more muscle in its mid-tier (series-600) mobile platform.

The Snapdragon 660 will be the first mid-range chipset to include Kyro cores and the Snapdragon 630 will add iterative refinements to Snapdragon 625. Both these chipsets will be formed on the power-efficient 14nm FinFET process and we will be hearing a lot about them next year.

Of course, the Snapdragon 845 will dominate tier-1 flagships.

Foldable Display Phones


[img]http://4.bp..com/-VuNdcgIbkDs/WkS_iq3ZsAI/AAAAAAAAAY8/Z_lR-boCZ-IDmIIpB-3HptoyCrcb0XiOwCLcBGAs/s640/foldable-phone.jpg[/img]
Many smartphone manufacturers have been filing patents for foldable display phones for many years now. Samsung actually showcased a foldable smartphone prototype way back in 2011. Also, Microsoft put some weight behind the tech and also filed a patent for what looks like the future ‘Surface Phone’.


This is naturally being viewed as the next revolution in displays and a means for adding an even bigger size screen without bloating the size.

I don’t expect foldable-displays to go mainstream the same way as 18:9 full-view screens anytime soon but I'm quite optimistic that the world will have witnessed a fordable display gadget by the end of next year.

Better 2X Zoom and Software based portrait mode

Dual cameras became quite popular this year however most premium phones use the extra sensor for 2X zoom and in low light, the zoom is still digital and reliant on the main sensor.

Next year,I expect more OEMs relying on software for Portrait mode and flagships will strive towards perfecting their Zoom capabilities. Chinese OEM Oppo is already working on a periscope-like lens assembly for 5X optical zoom without any camera hump and other OEMs are expected to innovate on similar lines.

Augmented Reality,

What actually is Augmented Reality? In a layman's understanding I would define it as the ability to see evil spirits from your phone's camera.(Welcome to Africa lol). However, if you're familiar with Pokemon Go , it should give you a little idea of how AR works. Google and Apple put their approval stamps on AR with ARKit and ARCore SDKs and the same should yield something more meaningful than AR Stickers by the next year.

[/img]
The iPhone X and Google Pixel 2 duo have the necessary hardware for the promised AR push and developers are already working on leveraging the technology for future updates

Artificial intelligence

Apart from AR, Artificial Intelligence should play a bigger role in enhancing smartphone experience next year. We already have phones marketing AI-based software (and assistants) across different budgets. Siri, Cortana, Alexa And Google Assistant should get a boost next year

Phones like Pixel 2 exemplify the power of software in overcoming hardware constraints. The phone integrates AI based refinements to improve numerous aspects including camera performance.

Google isn’t alone, though. Huawei’s Kirin 970 chipset uses the separate neural processing engine for AI-based resource allocation to avoid inadvertent lag that creeps up in Android phones over a period of usage. Even Oppo is marketing an AI-based beautify mode in its new set of selfie experts.

Next year, the scope and reliance on AI and machine learning in smartphones is expected to broaden.


Apart from the changes mentioned , you might finally get the promised high-density batteries or get to experience one of the many battery revolutions under works. A lot is happening right now and it’s still not crystal clear what 2018 might or might not have in store, but things look really good for now.

Virtual Reality would also improve next year.

Bro, which phone do you think is Ideal to buy between Infinix Hot 5 and Tecno Spark K9

Apart from the battery and price

Get the Spark K9

My friend...Oukitel is on Gsm Arena

I was referring to infinix not oukitel, My stats are actually based on specs and global sales, oukitel and Xiaomi are very good devices but i'd say they didn't make the cut for me. Although I acknowledge I skipped the Mi Mix 2 but I'll definitely add it on my next post

Frequency Compatibility issues.
