I also read that Samsung actually knew the risk but decided to "push it". They paid for it dearly if that is true.
In any case, I returned my device long ago because there is no chance I would pay that much money for a possibly compromised device with many disadvantages. For the future, I hope Samsung wises up, starts making safe phones again and explains the situation, otherwise I can't buy from them anymore.

This isn't new "news", but having a major article highlight what we have pretty much known was the issue is nice. Hopefully Samsung sheds some official light on the subject, but they are probably hoping it just fades away so they won't bring attention to it. I really hope they don't lower the Display to body ratio on they next phones - one of the nicest things about the N7 is the high display to body size ratio. They were able to get a very high display to body ratio in the S7, with a bigger battery than the N7 even, without problems, so they can do it. Yes the N7 has the S Pen which takes up space, but there has to be a way to get a 3600 size battery (or bigger) into the next Note phone without having this issue. Maybe if they go with a slightly bigger display (5.8 to 5.9) that will allow more room to work with. Same high display to body ratio but slightly bigger display and internal room to work with. Very interested to see what the S8 has in store, as that will likely give us an idea on what the N8 will be looking like.

I just can't quite understand why making the size of the phone so thin is of such overriding importance, especially considering that most people want a phone with a decent sized battery that will last for a decent amount of time. Seriously, what is the difference if they put a 4 or 5k sized battery and the phone is .5mm thicker.

This is a bull**** article written by hacks who have zero journalistic or scientific credentials, or even skills. None of it is true.
The original batteries did indeed caught on fire ( not exploded) because of a manufacturing defect by Samsung SDI, which was fixed after the first recall by switching to a different manufacturer.
To get at the truth one only needs to look at the, GASP - FACTS.
There were five "explosions" after the first recall, and ZERO after the second.

complete bs and samsung knows it.

Agreed. The people saying it was an aggressive design are idiots. Other phones use the same aggressive design and even higher mAH batteries. We wont know the truth until samsung releases their findings.

We were promised official results before the end of the year. Let's hope that holds true.

Why do people feel so threatened by the possibility that this is actually true? It is obvious it wasn't batteries alone, since they x-rayed every single battery yet the still went pop. It is still obiously a rare problem and whoever wants may still keep their phone regardless??

We want the results from SAMSUNG themselves. Honestly, considering the very small amount of failures out of the number of devices sold....

This does look pretty amazing although you would want to be a wealthy enough man to purchase this at €199 it's not even on sale yet but i can see this doing well with people who spend a lot of time outdoors away from electricity like explorers,etc.
Something like this would be great at a festival or if you were just out and about for a period of time and your phone died and nowhere near electricity and you needed it charged up.
What do people think to this?
I think hydrogen is harder to find than sunlight.
Seeing as they Don't even say how it works under the section "how it works" and seeing as hydrogen or Cole fusion is not invented yet to a point of usefulness (and would not be invented just by some company just to power USB devices...).
I'm going to go with it a Battery on one side and a tank that holds water and dose nothing on the other side till proven other wise... Also wouldn't that vary easily become a Boom, a vary big boom?
I Call Shenanigans!
I don't know about the ins and outs folks i just seen this website and had a look and it does look like a superb invention.
Cool piece of tech, it's just a mini fuel cell but to be honest I think practically you're better off with a big battery. I have a usb one with a 5000 mAh capacity and it's smaller than my phone and it was only cheap. Gives me 4 whole charges of my phone and I'm never not near a wall socket for any longer.

looks a bit more affordable for sure,please report back and let us know how this is.
This is the one I got:
http://www.ebay.co.uk/itm/PortaPow-Premium-USB-Battery-Pack-5000mAh-Dual-Sockets-/220639367439
It's thicker than the SGS2, about the same width and a bit shorter. It's good, holds it charge well and does seem to hold up to the 5000 mAh spec quite well

Real Cause of The Galaxy Nexus turning itself off at random

I posted this to reddit before here, but it will probably get more exposure on this board. Basically:
I seem to have stumbled upon a manufacturing flaw in the Galaxy Nexus's motherboard battery. Because I couldn't get a free exchange, I was free to open my Galaxy Nexus.
It was my hunch that battery pulling the motherboard's battery [which is basically like a CMOS pull in a PC conceptually] to reset it and get the device to boot.
Before that, the voltage on the battery was checked and it was already down to 2.4 for a device purchased in March. There are but a few months left on this battery and would have to replace it inevitably.
After searching the internet, this has appeared to happen to many people, but has never been addressed in this manner. So, this may be a real issue where poor sets of batteries have gone onto the GNex motherboard.
Unfortunately, I did this repair on the fly late last night, so I have no pictorial evidence. My next step is to identify the battery used on the device, purchase it, and do the solder job required to install it. Of course while taking proper documentation for evidence.

Any luck with this? Mine just happened to die on me after a couple of months of ownership. After I had it looked at, the tech informed me that I'm getting some sort of short on the motherboard. This is really a damn shame since coming from an iPhone, I really enjoyed this phone for the short period of time.
Trying to resurrect the ole' Gnex that silently slipped into blackness. Did you ever find a source for these little CMOS batteries?

Samsung will reveal the cause of the Galaxy Note 7’s exploding battery this Sunday

The Verge is reporting that; "Samsung will reveal the cause of the Galaxy Note 7’s exploding battery this Sunday"
Moment of Truth?
Can't wait. So we can finally move on and they can finally make a good phone for us again.

Hoping this is a simplistic assumption. There has to be a bigger/broader explanation. Apple, LG, Sony, etc. (put in the same position) wouldn't sacrifice billions and loose a whole product line over "just battery issues". They would recall the device, blame the battery manufacturer and replace the battery with a more reliable one. I could even see a scenario in which the replacement battery has a slight spec bump for "goodwill and PR purposes".
No, there has to be more at play here like an inherent design flaw. Perhaps one that only allow for limited high capacity battery options given the allotment of space in the device as has been reported elsewhere.
Lets just hope they are truthful, yes?
it's seeming likely what some have guessed of there not being enough expansion room for the battery being the second battery issue, as if that was the problem they would need to totally redesign either the battery to be smaller or reengineer the frame and everything else in the phone to free up space for the battery expansion, this is the only way I could it see it being an issue that is unfixable in a reasonable time frame.
but really until we see what they release everything is just guess work, just have to hope the release a bit more detail other than just "battery issues"
I doubt we will get the whole, complete truth. Just enough to regain confidence of consumers and investors.

What difference does it make? The reason the Note7 was killed wasn't just because of a mysterious overheating issue. There's no question that with time Samsung could have figured it out and corrected it. Once the Note7 became a global laughing stock and lightning rod for negative hits on Samsung's reputation the choice was allow the Note7 to flounder in the public eye while they tried to fix it or kill it.
Here's the S7 Edge and Note7 overlaid. They are virtually the same size. Note the similar width.

Look at the internals.
The silo for the S Pen takes up almost half an inch vertically running parallel to the battery. To keep the Note7's battery capacity and physical size comparable to the S7 Edge Samsung crammed ten pounds of sh!t in to a five pound bag. To "fix" the Note7 would have required a new smaller capacity battery and/or a complete retooling of its internals. The latter would have taken months which Samsung didn't have. The cost of a fix probably wouldn't have been much cheaper than pulling the plug. So they did. Simple as that. It was a business decision that killed the Note7. The issue leading up to its death was both a technical and ego drive one in that Samsung tried to deliver too much in the packaging they chose and pushed the technology available beyond its limits. A future case study for business majors.

WTF?
This is what they gonna share? This is even less BS than the first guess anyone made when the first battery exploded!!!
This is as retarded as saying "the Battery exploded because of fire inside the phone, because we made bad phones".
xD
http://www.gizmodo.com.au/2017/01/live-samsung-talks-about-the-exploding-galaxy-note7/
Interesting, but not surprising. Most interesting is two different issues in both sets of battery production. Basically the way the battery was manufactured to meet the specs of the phone size (and the SPen added less room to fit the battery so now we know why the N7 had a slightly smaller battery than the S7) meant building a battery that was just too tight for Lithium battery chemicals. But still two different issues in both different productions of the batteries (original run, and 2nd run after the first recall).
I can't help but notice they said failures happened early in the life of devices. So maybe holdbacks were right all along and why are they now pushing to get the last few percent back? I am NOT saying people should keep them, I don't know what this means. If someone can clarify if they know more about these things...
I thought one of the presenters said battery B's is problem is more likely to occur later in life.

Hmm interesting. Wonder if thats going to happen. Im so fed up with my G3 LG by now and its only been a month or so with it. Miss my N7, still waiting to get some good news on reactivating the thing.
On another note, where all the smart asses who kept telling me it was the battery fit that caused the fires??
This is how Samsung plans to prevent future phones from catching fire

They did but they didn't say at what point in the tests the ones with manufacturing defects failed nor did they say how many of the 200k phones and 30k batteries failed.

Anyone else had their display loosen at the top?

I've noticed this on my phone, and my Nan's. Both 3's, not 3T's. Both have loose screens at the top. - I can lift it up a lot. See photos.

Wonder if this is a more widespread problem, I've bought a Tudia case as it wraps over the edges of the display and holds it together, preventing it from worsening and falling apart.
Yep, i have the same issue on the top right side of the phone.

This sucks. I run LineageOS with a Locked BL, my friends and family also do with the 3 & 3T.
That sucks. If spontaneous and not from damage... it's a manufacturing defect.

It could be a battery failure although that battery is in the lower quadrant I think.
Especially after a year old keep an eye open for signs of swelling.
Any battery swelling is a battery failure, replace immediately.

Been an easy fix... that really sucks☹
On some phones it bulges and/or pushes out the display, on others the rear cover*.
At that point it may have already damaged the display or more.
This type of battery failure is fairly common.
Replace degraded Li's once they reach 80% on their original capacity.
Degraded Li's are more likely to fail.
Failures include thermal runaways...
*I had a failure on my 10+ recently and was luckily it didn't damage the display. The battery wasn't quit 1.5 years old.
Erratic fast charging is another sign of a failed Li.

Correct. I always charge at 2A and use Accubattery for monitoring. Unless I am in a rush, then I fast charge.
And yes, it is an easy fix, when it isn't the battery. But the displays are weak on the OP3 & 3T - and as a result, its easy to fek this up.
I once had a HTC One X bulge so badly it pulled the screen up about 2cm and broke the entire phone. Since then I've always taken care of batteries.

Question Pixel watch 2022, thoughts.

Since they dropped almost every new device because of the chip shortage, I wouldn't get my hopes too high. I remember 9to5 making a lot of news about the Pixel Fold, only to have other Tech sites 3 weeks later claim that it's a dead product for now.

I think they might go for it considering the amount of pixels they are selling atm it only makes sense for them to now have an eco system for it, they already have there own operating system for it wearos, so I hope they do

1) I run google free. The presence of the "assistant" was the part of the google spyware system that finally convinced me that it was time to get rid of it all. You should be very cautious about allowing anyone to spy on you. Read some George Orwell -- what they are ACTUALLY doing now was at that time seen as an unbelievable overstep.
2) I stopped wearing watches when I got my first cell phone. Why do I need to carry two things that do the same thing? The phone is a lot more convenient since it has a much bigger screen.
The whole idea of a "smart watch" is a gimmick. Don't fall into it.
Google might get into the smart watch game to compete with Apple and Samsung. I mean, it is logical. It is a good move to get into that market. I wouldn't be surprised if Apple starts making electric cars.
Oh good...another half baked device.
As long as I can sideload the Google Assistant to my Galaxy Watch 4 Classic I'd be happy
Maybe find an app that can rebind my HW Keys to replace Bixby too

That would be very frightening. They are not good at things that are complicated. If it happens, I'll be trying to come up with some means of detecting them (i.e. 360 degree visual) and alerting me when one is getting close so I can keep well clear of it.

I wish people could figure out that electric cars are not as "environmentally responsible" as they're made out to be. The reason Musk makes them comes down exclusively to the fact that you can't run an internal combustion engine on Mars. Tesla is a hell of an R&D lab for that.
