S7 – Samsung Rethinks Galaxy

Filed under: News — csadm @ 11:04 am

“It’s not just a new phone. It brings a new way of thinking about what a phone can do. You defined the possibilities and we redefined the phone. The Galaxy S7 and S7 edge. Rethink what a phone can do.”

That’s the official line from Samsung on the latest evolution of its smartphone.

It was only a year ago we saw the S6, so it is not surprising that the S7 has retained many of the design traits from last year’s model. The S7 is more about evolution, not revolution. The end result is a sleek, better-performing and more sensible phone. The result of Samsung’s process of “rethinking” is obvious.

The S7 and its big sister S7 Edge retain the metal and glass chassis, but there are some refinements such as a flatter home button, and a thinner protrusion for the camera. The rear of the phone has been rounded, giving the device a completely different feel to its predecessor.

However the most remarkable new features are an IP certification for water and dust resistance, as well as expandable storage. They certainly represent improvements on the S6. Some of the “new” features have appeared in previous models, although Samsung claim that their reappearance are because the technology has been refined.

The dropped waterproofing, with an IP68 rating is a handy feature. It means the phone can be immersed in 1.5 meters of water for 30 minutes before you need to panic. That’s plenty of time to take a deep breath and reach into the toilet bowl to retrieve your camera.

Samsung says that they have also worked out how to completely seal off the inside components whilst keeping micro USB ports, earphone jacks open, so you won’t have to fiddle with extra caps or covers.


The camera itself is now much improved, despite the drop in megapixel rating from 16MP to 12MP, designed to help improve low light capabilities.

While it sounds like a downgrade, in reality it’s a big change for the better, thanks to the fact that the lower pixel rating actually lets in more light – 25% more, thanks to the 56% large pixels being used.

According to Samsung, “some of our most precious memories happen after dark”. Now that’s an interesting observation. This is the first smartphone camera to have a professional-grade Dual Pixel Sensor with which you’ll now be able to take crisp, clear photos in the dark. With Galaxy S7 edge and S7, you own the night.

It also means that the front-facing “selfie” 5MP camera is much-improved especially in low-light situations.


Another “scaling down” has seen the Galaxy S7 only available in a 32GB model. Considering that Samsung offered 64GB and 128GB variants in the past, that doesn’t seem like much of an offer.

But in reality it’s a common sense move that improves the marketability of the phone. Rather than put prospective owners through the pain of understanding and deciding on memory capability, Samsung has simply added a microSD card slot in the SIM tray – something Samsung fans have been crying out for over the last 12 months.

The inclusion of expandable memory is a giant leap for the Galaxy, and it does not slow down performance of the phone.


The 5.1-inch screen is as pin-sharp as ever. Bigger and sharper in the Edge with its 5.5 inch screen. The high-res screen makes web browsing and watching video an impressive experience. The Super AMOLED technology used inside still offers huge benefits in terms of color reproduction and contrast, so everything looks stark and clear. It’s still the best looking screen in the market.


Samsung seems to have put a lot more effort into the battery pack with the Galaxy S7 – boosting it up from 2550mAh in the S6 to 3000mAh. The battery is non-removable and has an endurance rating of 80 hours.


The Galaxy S7 is one of the first Samsung phones to jump to Android 6, which comes pre-installed on the handset. That’s running on top of two different chipsets: the Qualcomm 820 CPU and Samsung’s own Exynos unit plus 4GB of RAM.

Both engines offer a huge amount of power and graphical grunt to make the stuff on the phone’s display shine.


The other big feature is the Game Launcher, a sandboxed area where you can store the latest gaming titles you’ve downloaded, and access a suite of tools to improve your gaming experience.

Game Launcher is the ultimate control center for games. All your games in one convenient place with new downloads added automatically. Before playing, you can mute and hide alerts and adjust game settings to save power.

You can also activate the Game Launcher set of tools to trigger some quick actions, like recording the screen or minimizing your game so you can do something else.


The two have everything in common except for the S7 Edge’s larger battery and screen size, and the S7’s conventional display versus the Edge’s curved screen (plus “edge” software navigation bar). Ask someone that has the S6 Edge and they will extol the virtues of the side navigation bar. Screen size of the S7 Edge is 5.5 inches versus S7 5.1 inches. Besides that it really is a matter of taste and budget.

Solar Power & Our Children’s Future

Filed under: News — csadm @ 12:00 am

Energy poverty is widespread across the Pacific Islands region, including Papua New Guinea where it is estimated that over 70 percent do not have access to electricity.

For the other 30 percent, including those living in the capital of Port Moresby, the power supply is unpredictable at the best of times.

That means your child’s studies are most likely being affected. If you care, D.Light solar power is the solution.

It seems strange in a country blessed with so much sun that solar has been overlooked as a primary source of power.

The sun is staring us in our face and it is free. At relatively low cost and little effort the sun’s life-giving energy is there for the taking.

Most of the planet is switching on to the benefits of solar power and there is a company that has led the way throughout Africa and Asia, providing households with affordable solar-powered solutions.

The name of the company is d.light and it sees itself as a global social enterprise providing solar-powered solutions for the two billion people in the developing world without access to reliable energy.

Through 10 field offices and four hubs in Africa, China, South Asia and the United States, d.light has sold over ten million solar light and power products in 62 countries, improving the lives of over 50 million people. d.light is dedicated to providing the most reliable, affordable and accessible solar lighting and power systems for the developing world and reaching 100 million people by 2020.

d.light was an initiative that dawned in 2004, when Peace Corps volunteer Sam Goldman’s fifteen-year-old neighbor was badly burned in a kerosene accident in Benin, Africa. Sam knew there had to be better, safer ways to power homes and businesses in the developing world. After returning to North America from the Peace Corps, Sam enrolled in Stanford’s Entrepreneurial Design for Extreme Affordability class, where he met co-founder Ned Tozun. In 2006, Ned and Sam founded d.light, developing the initial prototype solar lantern and an ambitious plan to bring safe, bright, clean lighting and power to people around the globe. d.light’s first commercial solar product made its debut in the marketplace in 2008.

CEO and Co-founder Ned Tozun said that the move towards solar power is empowering people all over the world.

“When we first pitched the business to investors, we were told that what we were trying to do as impossible. Our customers, employees and partners have proven that our business model of providing high quality solar products to off-grid families is not only possible, but it is serving a true market need across the globe.”

More than one billion people lack access to electricity in the developing world, with another billion reliant on power that is sporadic at best. Without a viable alternative, families are forced to turn to kerosene for lighting – a fuel that is expensive, inefficient and hazardous to health. Over a million people die each year from kerosene burns and indoor air pollution, and many families lose their possessions and homes to fires. Solar lighting provides an affordable alternative to kerosene, providing clean, safe, renewable energy that is replenished each day by the sun. To date, 50 million people in the developing world have been empowered by d.light products, allowing them to save money traditionally spent on energy and to increase productive time for working and studying, all while reducing the health and safety risks associated with kerosene and other forms of power.

d.light have products ranging from individual rechargeable solar lanterns to grid systems designed for the home and small business.
