Samsung phone fires not caused by batteries after all

A supplier in China has reported that a joint probe pointed to “outside factors” as the cause of the Galaxy Note 7 problems.

The Samsung phone fires in the Galaxy Note 7 have made their way to China. Videos of the exploding mobile devices went viral last weekend. Some stores in the country pulled them from the shelves while some new owners sought to return them.

However, the South Korean electronics company released a statement following device test results.

So far, the Samsung phone fires don’t appear to be caused by faulty batteries, as had been suspected. At least, that is what the company has been saying following the results of tests conducted on the devices. At least one of the exploding Galaxy Note 7 phones was heated from the outside, not internally, said Samsung.

There have been battery issues in versions of the device launched in other countries. The company is currently dealing with the recall of 2.5 million units in the United States and 9 other countries.

China is the largest smartphone market in the world, but it has not been impacted by the Samsung phone fires recall.

That said, it isn’t yet clear whether or not the statement from Samsung will be enough to assuage the concerns of consumers and merchants. The world has already watched the company cope with the massive recall of the first wave of fire-prone batteries in the smartphones. For a device that already retails for over $800, this could cause people – and stores – to think twice.

The widespread news of the exploding phones in China could be very problematic to the company, regardless of whether or not they are to blame. The fact that this is occurring in the largest phone market in the world must be causing some sweat to break out.

The tests were conducted by the battery supplier for the Chinese market phones, Amperex Technology Ltd. It conducted the tests jointly with Samsung using one of the devices that were part of the Samsung phone fires in China. The examination revealed that the battery hadn’t been the source of the problems.

Unbreakable phone screen may finally have been invented

Scientists have come up with a new technology that may make dropping your smartphone far less upsetting.

Scientists in the United Kingdom have announced that they have come up with a technology for an unbreakable phone screen. The tech involves the use of a special form of electrode. It would be possible to use it in mobile devices such as smartphones and tablets, or even in larger electronics such as TVs.

The team of scientists has predicted that the unbreakable screens could be available as soon as 2018.

The electrode for the unbreakable phone screen technology conducts electricity throughout the glass. A traditional form of electrode is made of indium tin oxide (ITO), which is an expensive type of metal. In fact, it is prohibitively expensive and has stopped that method from being used for more durable mobile phone screens until now. However, the UK scientist have made a new type of electrode by mixing graphene and silver nanowires.

These two materials were the key to being able to create the unbreakable phone screen display.

The thinness of these materials has made it possible for an exceptionally flexible conductor which is far more resistant to breaking and cracking than the current standard glass screens.

When taking into consideration the number of people who break their smartphone screens, this is very good news. After all, a cracked screen isn’t just an inconvenience. In fact, inconvenience is only the beginning. Touchscreens as a standard on nearly all smartphones have meant that cracked screens can limit the use of the device or can render it unusable.

The unbreakable phone screen technology was created by a team of University of Sussex physicists who were working with an Oxford microelectrics firm. They developed these unique hybrid electrodes and published their findings in the Nanoscale journal. According to that publication, this is also an important discovery because the graphene and silver nanowire combination is actually better at conducting electricity than the older electrodes made out of the expensive ITO metal.
