As we expect the Samsung S8 and even the Samsung Galaxy S9, there is a phone launched by Samsung that we need to take a look at, so we can decide who is King among the Samsung trio. Although, as at now, the Samsung Galaxy C8 price and availability details have not been officially announced yet- but details would be released soon.Samsung galaxy C8 Launch

Ahead of the launch, The Galaxy C8 is being subjected to several leaks and rumours, which suggested that the phone would come with two cameras at the rear and would feature a facial-recognition security measure. I noticed that the Galaxy C8 is the third samsung smartphone to arrive with a dual camera setup at its rear. The first one is the Galaxy Note 8 and the second one is the Galaxy J7+. Black, Pink and Gold are the three colors of the phone that we should all expect, according to the leaks we have.

Samsung has already announced the Galaxy Note 8 in its home market South Korea. The Note 8 was launched on August 23. It is a high-end phone with premium hardware and features. In India Samsung is expected to launch the Galaxy Note 8 with a price of nearly 60,000 in India.

Ahead of the launch, Samsung is asking people who will like to buy the phone to register themselves at a special website that the company has created for the Galaxy Note 8. People who register now will get the phone early, and there are massive purchase orders already.

The Samsung Galaxy C8 comes with dual camera setup (already said). The primary camera comes with a 13-megapixel sensor which is paired with an f/1.7 aperture lens. Samsung galaxy c8The secondary camera uses a 5-megapixel sensor along with an f/1.9 aperture lens. On the front, the new Samsung Galaxy C8 comes with a 16-megapixel sensor which is further paired with an f/1.9 aperture. The dual-camera system of the Galaxy C8 comes with Dual Photo mode. In other words, similar to what is there inside the Galaxy Note 8, this camera mode lets users adjust the focus of the picture even after capturing the image.

Also, the facial recognition technology added to this wonderful phone allows users to unlock the phone with their face. The Galaxy C8 also comes with a fingerprint scanner which is embedded in the home button at the front, right below the display. The Galaxy C8 also comes with an always-on display. On the connectivity front, the smartphone comes with range of options like — 4G connectivity, Bluetooth 4.2, Wi-Fi 802.11 b/g/n, 3.5mm headphone jack, and micro-USB port. The phone also comes with Bixby support. Did I forget to add that the Galaxy C8 houses a 3000mAh battery? no. The battery capacity is 3000mAh.

By recent observations, the popular gone-down phone maker Nokia, is soon going to launch three distinct Android handsets, but all three of them are mid-range devices at best by this year’s mobile standards. But what I have been seeing,the Nokia 9 supposed to be the flagship that will rival the Galaxy S8 and iPhone 8 this year. We’ve seen leaks that suggested the Nokia 9 will have specs that might be even better than the Galaxy S8’s. You don’t agree? Continue reading and perhaps, you’ll change your mind!

nokia 9 vs samsung s8

Nokia had some many customers about eight years ago, then the wave of androids made them go down in the phone market. But with the phones they are making, especially the Nokia 9 that is beating the samsung s8, Nokia carefully planned a massive come-back.

Nokia 9 might indeed sport an edge-to-edge all-screen design. The home button and its fingerprint sensor seem to be relocated to the back beneath a dual lens dual flash camera setup. That rear design looks a lot better than Samsung’s camera and fingerprint combo on the Galaxy S8.

Also, from the recent rumors of a Nokia 8, this latest speculation shows HMD Global is serious. Now whether that’s serious concerning stirring the pot, or actually developing and releasing these handsets is yet to be seen. However, is giving the dormant giant brand some traction on social media and various tech forums.

As for where the rumors were first brought to the attention of the public. That comes from a tip received by NokiaPowerUser, on April 1. Could this be a fools joke, it’s possible, although, we will take it as a tip-off nothing more.nokia 9

Before I go further, these are the rumoured specifications of the Nokia 9 that would make any respective samsung s8 user have a rethink:

  • 5.5-inch QHD OLED Display
  • Snapdragon 835, Adreno 540
  • 22 MP Dual-Lens Carl-Zeiss Rear Camera
  • 6 GB RAM
  • 64 GB / 128 GB storage
  • 12 MP FFC
  • 3800 mAH Battery
  • Qualcomm Quick-Charge 4
  • Iris Scanner
  • Finger-Print Scanner
  • Nokia OZO Audio Enhancements
  • IP68 certification
  • Android 7.1.2 Nougat

Y’all know the rumours I spread here tend to be eventually true, but let me make this an exception, as this is not from any of my trusted sources, so we urge to take it with a pinch of salt (even though I can assure you that there is a trend too and seems we can really expect a Dual-Lens Carl-Zeiss camera).

According to BGR,

[the_ad id=”2428″]

The Nokia 8, as the name suggests, will be a cheaper version of the Nokia 9. The render indicates the Nokia 8 will have bigger top and bottom bezels than the Nokia 9, and the home button will be placed on the back. The rear will still incorporate what appears to be a dual lens camera, although it has a different flash design.

It’s unclear at this point when Nokia will unveil new devices. The company should launch the Nokia 6, Nokia 5, and Nokia 3 in multiple markets around the globe by the end of the second quarter. Whether any of these Nokia 9 and Nokia 8 are accurate or not, the fact remains that Nokia isn’t done unveiling new hardware, and flagship handsets are only to be expected. What’s exciting about all of Nokia’s phones is that they’ll run a nearly pure version of Android, or at least that’s what HMD Global keeps promising.”

Final Notes:

The striking Differences Include:


To many, the 12MP rear camera, and 8MP front cameras found on the Galaxy S8 and S8 Plus are a letdown. Yes, Samsung has included a tweak here and there, but, fundamentally, they are the same that appeared on the S7 and S7 Edge. Meaning that Android smartphone users are still craving for some next-generation camera goodness, could the Nokia 9 provide this?

According to the report, that’s a yes, as it could feature a 22MP rear dual-lens camera and 12MP front camera. Both of which come from the long time Nokia collaborative partner Carl Zeiss. However, where the real fun comes into play is with the dual-lens. Apparently, it will offer, true optical zoom, something which neither S8 can supply.


It’s thought the Nokia 9 will also feature the Qualcomm chip. And while this isn’t exactly worth bragging about (in terms of this comparison) it is the most powerful Android based chip around. Making the Galaxy S8 and the Nokia 9, two smartphones that could be classed as the fastest.

However, while Samsung has chosen to back up the chip with 4GB of RAM, users wanted 6GB. It seems as though, HMD Global has been listening, as it will supposedly support the Snapdragon with a minimum of 6GB. Meaning, it should out-perform the S8’s. Additionally, an option to choose from either 64GB or 128GB storage options is also superior to the single 64GB on offer from Samsung.


It has been widely noted that 2016 was a terrible year for Samsung what with the Note 7’s battery issues. However, Samsung has improved its power management software, a reason why users will see improvements in battery life.

As for the difference in capacities between them and the Nokia 9, it is rumored to be getting a 3800mAh battery. While the S8 has a 3000mAh and the S8 Plus a 35000mAh power unit, which will come out on top? You would expect the larger capacity of the Nokia too; however, Samsungs promise of improvements may negate that. [the_ad id=”2430″]

The South Korean popular smartphone giant, Samsung, has  confirmed that it will bring the Galaxy Note 7 as a refurbished smartphone in some markets depending on regulatory approvals and local demands. The announcement appears to walk back on what Samsung initially pledged last fall, when it said it would dispose of the Note 7 and had no plans to repair or refurbish them. After announcing last year that it would simply “safely dispose of the phones,” the company today addressed plans to offer them back to the public in a newer, safer form. The move is an attempt to address vocal environmental concerns over its initial plans to trash a whole bunch of handsets all at once, no matter how safe it insisted the process would be.

Additionally, in an official blogpost, Samsung has announced that it has established three principles to ensure that all the Galaxy Note 7 units are recycled and processed in an environment-friendly way. First, the smartphone will be considered to be used as a refurbished or rental phone wherever applicable.

Second, reusable components and parts of the device would be detached for reuse. Third, valuable metals and other such parts shall be extracted using environment-friendly methods. This appears to be a walk back from the company’s plan to not bring back those units to the market.

Regarding the use of the Galaxy Note 7 as a refurbished or a rental device, the company will consult with local regulatory authorities, carriers, and local demand before releasing it in any market. The company will announce the release date of these refurbished units accordingly. For the remaining Galaxy Note 7 units, components such as processors and camera sensors would be detached by firms that specialize in this area, and those components would be used for testing and sample production purposes. The device is also rumored to be coming with a smaller capacity battery, so as to avoid the mistakes that got the company in hot water with two separate recalls during the seemingly endless saga, though Samsung is also apparently still working on those spec specifics.

As we all know the 7th generation of the Samsung Note did not live up to the of expectations Korean manufacturers.Tech enthusiasts all around the world suspect the cause of the explosion to the batteries.

According to battery expert Dr. Donald R. Sadoway, the John F. Elliott Professor of Materials Chemistry at the Massachusetts Institute of Technology (and onetime TIME Most Influential Person) to explain how batteries work, he decided to a little bit of battery chemistry.

He explained that :

[Lithium-ion batteries] are a classical battery in the sense that they have two electrodes separated by an electrolyte. In this case, the negative electrode is typically some kind of a carbon, like a graphite, and the positive electrode is a metal oxide, something like lithium cobalt oxide or lithium manganese oxide. The electrolyte, because it’s shuttling lithium, it has to be non-aqueous. They can’t use an acid or an alkaline solution, they have to use something that’s not water, and that’s part of the problem. It’s an organic liquid and so therefore it’s volatile and flammable. But it does dissolve lithium salt and it allows lithium to shuttle back and forth between the negative electrode and the positive electrode.

Let’s [talk about] the battery at full state of charge. At full state of charge, all of the lithium is up inside the negative electrode. It’s sitting inside the graphite. On discharge, the lithium wants to go from the graphite over to the cobalt oxide. So it takes a swim through the electrolyte and enters the cobalt oxide, and electrons go through the external circuit and power your devices. That’s what generates the current and so on.

In short Donald said,

What happened there was, somehow during the manufacturing process, very tiny particles of metal had ended up in the electrolyte . . . under the action of electric current, these metal fragments aligned, and they eventually formed an unbroken chain of metal from one electrode to another. So then you’ve got the current shorting through this filamentary wire, if you will, so you’ve turned the inner electrode gap into a toaster oven. That causes all of the current to short, and generates a lot of heat, and that causes the electrolyte to bloat, and then the next thing you know, it explodes.

If the temperature gets high enough . . . at some point, if you get up to about 400-500 degrees Centigrade, the metal oxide in the negative electrode actually starts liberating oxygen. And that’s really dangerous, because now, instead of having a fire . . . getting its oxygen from the air surrounding it, it’s getting its oxygen from inside the battery itself. The term of art is, this has now become a bomb. You’ve got fuel and oxygen in the same place at the same time.

Right now, it’s hard to tell exactly what’s causing Samsung’s problems. But Sadoway has some theories:

It’s either a statistical fluke in the manufacturing process where there are some local hotspots or there are perhaps some metal shavings, some kind of a shorting. But it seems as though, from what I’ve been able to read, the fires occurred when the owners are charging the phone. That means that while they’re forcing current through it, somehow there is a side reaction that is very different from just recharging the battery. And that starts charging the battery, and then the thing goes into thermal runaway.

So what are lithium batteries, this is a type of rechargeable battery  in which lithium ions  move from the negative electrode to the positive electrode during discharge and back when charging. lithium batteries are common in home electronics, smart phones, e.t.c.

lithium batteries are the best in the market, they are one of most popular types of rechargeable batteries in the market because of their high density, tiny memory effect, and low self charge.

Like I said earlier,leaving all the nerd stuff behind,samsung has decided to carry out an investigation to reveal cause of the Note 7 problem before the end of the year and it seem they are making headway with their investigation

According to gsmarena, Samsung conducted an internal investigation which as been completed and the results have been sent to the Korea Testing Laboratory and UL (an American safety organization), among others. The report is, however, yet to be released to the general public (us included).

Meanwhile, Instrumental suggested that extremely tight internal margins were the reason for the exploding batteries, but that remains to be confirmed by Samsung’s own analysis.

The Samsung Galaxy Note 7 lost its popularity,
shortly after its launch in August this year when reports emerged of phones overheating, setting on fire, and even exploding.

Even though there were only 35 incidents out of more than a million phones sold, Samsung issued a full recall-and-replace order… until the replacements started exploding, too. Samsung has since issued a full recall on all remaining Galaxy Note 7 devices and even suspended production.

But the Galaxy Note 7 is not the first device to be recalled for this reason, and it probably won’t be the last. In 2011, Apple recalled a batch of its first-generation iPod Nano devices. In 2007, Nokia recalled 46 million phone batteries, and there have been more than forty other such recalls since 2002.
Here as usual,, we’ll explore just what the heck is going on and whether or not you need to worry about this with your own smartphone.

Why Do We Use Batteries That Explode?

All of our portable electronic devices (i.e. phones, tablets, laptops) use Lithium-ion batteries. Pound for pound, Lithium-ion batteries provide far more energy than other types of batteries — around twice as much as Nickel Metal Hydride (NiMH) batteries and around six-times as much as the lead-acid batteries used in cars.
This is important in an industry where weight (or lack thereof) is a huge selling point.

We all want our phones to be as light as possible yet still last at least a full day without recharging — and at the moment, Lithium-ion is the best technology we have that lets us do that.

But Lithium-ion batteries have a few disadvantages, too. TBut Lithium-ion batteries have a few disadvantages, too. They have a short shelf life, only lasting about 2–3 years from the date of manufacture, and that’s regardless of whether they’re actively used or not. If they fully discharge, they’ll never work again. And occasionally they explode.

To understand why this happens, it’s necessary to know a little about how Lithium-ion batteries work internally.
Like all modern batteries, they store and release energy through controlled chemical reactions. A current flows between two electrodes (an anode and a cathode) through chemicals called electrolytes. Lithium is highly reactive, which is what gives these batteries such a high energy density — but it also means that if something goes wrong, the results can be terrible.

So, What Can Go Wrong?

There are a few things that can go wrong with a Lithium-ion battery and they all involve overheating. If one part of the battery gets too hot, then it can lead to a chain reaction known as “thermal runaway” — the whole battery gets hotter and hotter until it ignites or explodes.
Because of this, Lithium-ion batteries have an on-board computer to ensure they don’t overheat. If this fails then overheating can occur, especially on a hot day or when the device is being heavily used. Overcharging can also lead to overheating, but again, the battery’s internal computer should prevent this. Unfortunately it may fail to do so, whether due to a manufacturing error or because the computer itself has sustained damage.

What Went Wrong for Samsung?

It’s not yet clear exactly what the issue was with the Galaxy Note 7. The company has blamed “a very rare manufacturing process error” which caused the anode and cathode to come into contact. Further investigations are underway. Samsung has stated that none of its other products are affected by this issue, and there have not been a significant number of incidents involving their other products.
Remarkably, some people have decided that the Galaxy Note 7 is such a good phone, they’re going to hold onto theirs despite the risk. This is, to say the least, a rather reckless approach, and while the risk is small, it’s unnecessary to take it. There are plenty of good alternatives on the market, including some of Samsung’s other products.

Should You Be Worried?

Although the consequences of an exploding battery can be catastrophic, it’s an extremely rare event.  You’re more likely to be struck by lightning  — which would probably also cause your phone to explode! But there are some steps you can take to reduce the odds even further:
  • =>Only use the original battery, or one from the manufacturer, or a reputable brand.
  • =>Don’t leave your device in hot areas, particularly while charging. Keep it out of direct sunlight, and make sure it can dissipate heat effectively.
  • =>Have a protective case for your phone to avoid puncture damage if you drop it. But take the case off if the phone gets too hot. The phone will almost certainly shut down before the battery gets hot enough to ignite, but the heat can still shorten the life of the battery.
  • =>Do not use a cracked or swollen battery.Remove it from any device and do not attempt to charge it.
  • =>Dispose of old or damaged batteries responsibly. Take them to a recycling center, or to a electronics retailer who will be able to dispose of them properly.

The manufacturer is trying to make up for the disaster, but the consumers are fed up with this year’s flagship because it’s simply not safe to use, and now they are looking forward to see the Galaxy S8 get launched in the first quarter of next year. The Galaxy S8 can wash the company’s image and the execs’ hopes are based on this. We’ve seen a few rumors regarding the upcoming device and if they are accurate, the smartphone looks pretty promising.

(adsbygoogle = window.adsbygoogle || []).push({});

ccording to a leaker who posted a spreadsheet on Weibo, the Galaxy S8 edge will have a 5.5-inch 4K Super AMOLED display — that’s 3840 x 2160 resolution and 506 ppi pixel density). Samsung is also putting a lot of work into curved screens, and a recent comment from Samsung Mobile President Dong-jin Koh claimed: “Samsung has considered that it would make the edge display the identity of the Galaxy S smartphone lineup.” Interestingly, the screen will supposedly account for 80% of the front side of the handset, which seems to imply that Samsung is going to ditch the home button next year.
The battery isnt mentioned.Furthermore, the phone is said to have either a Qualcomm Snapdragon 830 processor or an Exynos 8895 chip, which means in either case will will sport a 10nm chipset. Finally, the leaker says the phone will have either 6GB or 8GB of RAM, which is impressiveNo matter how exciting all that sounds, this is still just a rumor so treat it accordingly.

After all, there’s no telling how the Galaxy Note 7 mess will affect Galaxy S8 production, especially given that the phone is expected to introduce a brand new design.

This phone is expected to be around $850 and £775
