South Korean Team Develops Material That Makes Your Smartphone Screen Unbreakable



South Korean Team Develops Material That Makes Your Smartphone Screen Unbreakable 1
This isn’t the first time we’re hearing of a self-healing
material for smartphones. Late last year, a team of Scientist at University of California Riverside invented a phone screen material that can heal itself. 

Prior to this, if you drop your phone and the
screen shatters, you usually have two options: Get it repaired or replace the
phone entirely. But with this latest discovery, it shattered your two options and
present you with a third option…self-heal itself.

Phone screen scratches without solution may soon be a thing
of the past as a team of Korean researchers have developed a new
self-healing material called “Elastomer,” which can restore dents and cracks
within 30 minutes. Elastomer is high molecular substance that is able to
stretch and shrink.
During the cause of this research, the new material was able
to recover 80% of its tensile strength in just two hours during a test that
carried out cutting and rejoining. After six hours of the test, it even showed
tensile strength that was able to lift a 5kg dumbbell.

The team also disclosed that the new material can be used as a protective layer
on mobile devices and it automatically restore any outside cracks within 30
minutes. No matter the degree of scratches on the screen of your device, it
wills self-heal itself.

However, the use of self-healing materials for smartphone
screen maybe a long term project before it comes to reality.

Vulnerability in RCS messaging could compromise your bank details




German security company SRLabs has recently discovered a serious security breach that could replace SMS. According to their findings, the RCS protocol has a vulnerability that allows your data to be intercepted.

Hackers could exploit this vulnerability locally or remotely. Among the information they can intercept, we have unique codes that are sent by message in two-factor authentication systems.

One of the applications of these unique codes is in the authorization of bank transactions. This means that in extreme cases your bank details could be compromised due to this vulnerability.


Android messaging should improve your domain verification system

As SRLabs points out, the most popular application supporting RCS technology is currently Android Messaging. According to its findings, this application does not properly verify domains.

This means that miscreants can spoof caller ID or DNS. Something that could mislead users and provide information they shouldn’t.

Coincidentally or not, Google revealed this week that it will accredit message senders in your app. The idea is for companies to register their contact numbers with Google so that they can validate them when communicating with users. A measure that will certainly reduce the impact of this vulnerability.

What is RCS and its differences from SMS

The acronym RCS stands for Rich Communication Service. Briefly, this protocol allows messages to be sent over the internet. The SMS protocol uses cellular networks to send messages.

Vivo S5 will have a very peculiar triple rear camera, reveals official image



Vivo S5 will have a very peculiar triple rear camera, reveals official image 13

We are just a week from the official presentation of Vivo S5, the next mid-range smartphone to be launched by the brand. Now, an official image published on the Chinese social network Weibo, has confirmed several details about the design of this smartphone.

According to the picture, the Vivo S5 will come with a rear ‘quad-chamber’, centred on the rear panel with a diamond shaped module. In addition, it will come with a small punch-hole in its screen, where the front camera will be embedded.


Vivo S5 has confirmed design on the official poster

In the diamond-shaped module, three of its four cameras are integrated, and the LED flash. The fourth chamber is positioned immediately below the ‘protrusion’.

In the front panel, we can confirm that you will not have a notch on the screen by choosing a small punch-hole in the upper right corner, where your front camera will be embedded.

Although visible, their margins appear to be quite thin, ensuring an immersive user experience. In addition, an AMOLED screen is confirmed as an on-screen fingerprint reader is present.

Alleged Vivo S5 Specifications

Although not officially confirmed by the manufacturer, certification of the smartphone at TENAA agency eventually revealed the main details about its hardware.

  • 6.44 “inch AMOLED display with Full HD + resolution
  • Qualcomm Snapdragon 712 Processor
  • Up to 8GB of RAM
  • Up to 256GB of internal memory
  • Four rear cameras: 48MP + 8MP (ultra wide-angle) + 5MP (depth) + 2MP (macro)
  • 32-megapixel front camera
  • 4,010mAh battery
  • Android 9 (not confirmed)

Regarding its price, there is no information yet. Still, it is expected to arrive at a competitive price, which could possibly be around € 250.
