Sony has announced their latest interchangeable lens camera, the Sony A9. The company is claiming it to be the most technologically advanced and innovative digital camera they have ever created.

Sony A9

The camera supports continuous shooting at 20 frames-per-second (up to 241 RAW images). Moreover, the electronic viewfinder will not be blacked-out, enabling the user to see what exactly is being captured. It boasts of a maximum shutter speed of 1/32,000 second. The sensor used is a full-frame 24.2 MP Exmor RS CMOS. It is paired with an upgraded BIONZ X processing engine.

The shutter used is electronic and is thus free from any vibration or noise. The battery used is a Z battery, with double the capacity of a W battery. There are two slots for extending the storage via SD cards, along with an Ethernet port. If required, same data can simultaneously be recorded to both cards.

The camera is equipped with a five-axis image stabilization system. Focus can be set via the joystick fitted at the rear of the camera, or by touching the LCD.

Sony A9 can record 4K (3840x2160p) videos. The raw footage is collected at 6K resolution, which is then over-sampled to produce a high-quality 4K video. FHD recording is done at 120 fps, which can then be edited to create 4x or 5x slow motion videos.

We are well aware of what heat does to an electronic device, and how different devices use various cooling mechanisms (fan, water, and so forth) to prevent them from overheating or shutting down altogether. However, can the same dreaded heat be used as an alternative source of energy to power up those devices? Engineers at the University of Nebraska-Lincoln seem to think so!

A thermal diode

They have developed a thermal diode to achieve the same. As the name suggests, it runs on heat (as opposed to the traditional ones that use electricity). For the uninitiated, a diode is a logic component in electronic circuits that allows electricity to flow freely in one direction while blocking it from flowing the opposite way.

“If you think about it, whatever you do with electricity you should (also) be able to do with heat because they are similar in many ways,” said Sidy Ndao, co-author of the study. “In principle, they are both energy carriers. If you could control heat, you could use it to do computing and avoid the problem of overheating.”

In the paper published by the team, they have claimed that the diodes are working as expected for temperatures up to 630 degrees Fahrenheit (332 degrees Celsius approx.). They expect it to work at temperatures as extreme as 1300 degrees F (704 degrees C), which can then be deployed in computers that can operate in extreme heat conditions.

“We are basically creating a thermal computer,” Ndao said. “It could be used in space exploration, for exploring the core of the earth, for oil drilling, (for) many applications. It could allow us to do calculations and process data in real time in places where we haven’t been able to do so before.”

If all goes well, this will result in improved energy efficiency as the heat energy that gets lost now can then be reused to power the device.

“It is said now that nearly 60 percent of the energy produced for consumption in the United States is wasted in heat,” Ndao said. “If you could harness this heat and use it for energy in these devices, you could obviously cut down on waste and the cost of energy.”

“If we can achieve high efficiency, show that we can do computations and run a logic system experimentally, then we can have a proof-of-concept,” said Mahmoud Elzouka, co-author of the study. “(That) is when we can think about the future.”

Since diodes are not the only component present in an electronic device, this can be considered as the first step towards achieving a thermal computer. Scientists need to find ways for other elements to operate at higher levels of mercury.
Gionee S10, the alleged successor to last year’s S9, has been spotted at the Chinese certification website TENAA.

Gionee S10 front and rear

The device is expected to feature a metal unibody design, just like its predecessor. It will sport a 5.5-inch FHD display, with a resolution of 1920x1080 pixels.

The rear camera on the device will be a dual lens setup, with each lens being 13 MP. The secondary camera will be a 16 MP shooter, apparently hinting at another selfie-focused smartphone after the recently launched A1.

Gionee S10 sides

Gionee S10 will run on an octa-core chipset clocked at 2 GHz. It is safe to assume it will be the MediaTek Helio P20 since P10 was the one used in Gionee S9. The smartphone will feature 4 GB RAM with 64 GB internal storage, which will be expandable up to 128 GB via microSD.

The battery capacity will be 3,700 mAh. The fingerprint sensor will be embedded in the Home button in the front, just like its predecessor. The device supports 4G LTE and VoLTE. It will run on Android 7.0 Nougat out-of-the-box.

LG's latest flagship of the famous G series, the LG G6, was recently launched at the Mobile World Congress. LG V20, another flagship phablet from the brand, was also announced recently. How do the two devices from the same manufacturer stand against each other? We try to find out.

LG G6 vs. LG V20

Battery capacity

LG G6 boasts of a 3,300 mAh battery, while the LG V20 has a 3,200 mAh battery. Thus, the G6 has around 3% larger battery capacity.

Battery type

G6 comes with a non-removable battery, while the LG V20's battery can be removed.

Color options

G6 offers black, platinum, and white variants, while the V20 comes in gray, pink and silver.


G6 boasts of an aluminum frame along with glass panels at the front and rear, while the V20 comes with an aluminum unibody design.


LG G6 is 148.9 mm in height, 71.9 mm in width and 7.9 mm in depth. LG V20 is 159.5 mm in height, 78 mm in width and 7.6 mm in depth. Thus, V20 is around 7% taller and 9% wider, while the G6 is 4% thicker in comparison.

Display aspect ratio

LG G6 comes with an unusual aspect ratio of 18:9, while the LG V20 features the usual 16:9 aspect ratio.

Display pixel density

G6 boasts of a pixel density of 565 ppi, while V20 has only 513 ppi. Thus, G6 has 10% higher pixel density.

Display resolution

G6's screen has a resolution of 2880x1440 pixels. V20 features a QHD display, with a resolution of 2560x1440 pixels.

Dual screen

G6 has only one screen, while the V20 features a second smaller screen above the main display to house shortcuts and notifications without interrupting the primary display.

Internal storage

G6 offers 32 GB memory, while V20 has doubled the built-in storage.


LG G6's pricing is yet to be revealed. LG V20 is available at an average price of approximately $682.

Primary camera

LG G6 comes with a 13 MP standard lens, along with 13 MP wide-angle lens. The LG V20 boasts of a 16 MP standard lens along with a 8 MP wide-angle lens.


G6 runs on the latest Qualcomm Snapdragon 821 quad-core chipset clocked at 2.35 GHz. V20 runs on Qualcomm Snapdragon 820 quad-core processor clocked at 2.15 GHz.

Water resistance

G6 comes with IP68 certification, while the V20 does not have any such feature.


LG G6 weighs 163 g, while the V20 weighs 174 g. Thus, LG V20 is almost 7% heavier.

Wireless charging

LG G6 models available in the US support wireless charging, but the V20 has no such feature.

Other common features

  • 5.7-inch IPS display
  • 5 MP secondary camera
  • f/1.8 primary camera aperture size
  • Optical Image Stabilization (OIS) supported
  • Qualcomm Quick Charge 3.0 supported
  • 4 GB RAM
  • Memory can be expanded up to 2 TB via microSD
  • Headphone jack available
  • Fingerprint sensor at the rear
  • NFC supported
  • Android 7.0 Nougat with LG's skin on top


Since the LG G6 is not yet available, it is tough to declare a winner by just the specifications. However, if you are an audiophile who prefers phablets, there is no point waiting for the G6, and LG V20 is the choice you must make. Otherwise, it is worth waiting for the price at which the LG G6 will be offered. One downgrade in the G series from the Korean giant is their moving away from the modular approach applied in LG G5.
If you were born in the 90s, you must remember the popular 'brick' phone by Nokia. If not, you might know of your parents owning one. Yes, I am talking about the Nokia 3310. That was the time when phones were meant to break the floor they fall on, and not to get smashed to pieces themselves (this is not true, but I am sure you understand what I mean). HMD Global, the team that now uses the Nokia brand name, has relaunched the iconic feature phone at the ongoing Mobile World Congress. Nokia 6, Nokia 5 and Nokia 3 are also announced.

Nokia 3310

The device comes with a 2.4-inch QVGA(320×240 pixels) display. It is an upgrade to the original model which featured a monochromatic screen. It comes in single and dual-SIM variants. The newer model is flatter and rounder in comparison to its predecessor.

16 MB internal storage powers the Nokia 3310. It is expandable up to 32 GB via microSD card slot, which is a first when it comes to feature phones.

The primary camera is a 2 MP lens with LED flash, yet another first for feature phones. We do not expect a secondary camera, and there is none.

The phone is packed with 1,200 mAh battery. If the company claims are to be believed, the expected standby time is 31 days (one full month!) while the talk time is 22 hours. The device runs on Nokia Series 30+ operating system. The famous Snake game has also made its way back and is available on this phone by default.

Nokia 3310 comes in red and yellow color variants with a glossy finish and blue and gray with the matte finish

Nokia 3310 comes in red and yellow color variants with a glossy finish and blue and gray with the matte finish. It is priced at €49 ($52/₹3,500 approx.). It will be available second quarter onwards later this year.
