WhatsApp: Here are 5 Hidden Functions and Methods that Everyone Should Use

The world of WhatsApp is much bigger than you think. Here are some of the less known functions and methods that you should all use.

All the people who own a smartphone nowadays, know that there is a circle of apps to download almost obligatorily. To do this, each operating system makes available a market with lots of games and applications.

Among the various apps to download, the first ever is of course WhatsApp, application famous all over the world and of which everyone knows now the main functions. But certainly there are many users who do not know some of the most incredible hidden functions ever. Precisely for this reason we are here with the aim of illustrating 5 of them that could certainly serve you in the future.

1. Send messages to unsaved numbers in Address book you can, here’s how

To do this you will need a third party application that you can download from the Google Play Store. This is WhatsDirect – Tool for WhatsApp. Once downloaded, simply enter the telephone number of the unknown person, preceded by the national prefix. Then you write the message and you will see that the initiated conversation will appear in WhatsApp.

2. View the messages in chat without updating the display time

To do this will suffice a single and only really very simple passage but not everyone thinks. When you receive a message you need to read but don’t want to show others that you have just entered, the process is very easy.

Once you get the message you want to read before you do so, disconnect all internet connections. Then enter the app and read the message quietly. Then exit, and reactivate all connections. You will not have left any trace.

3. Deleting messages already sent in WhatsApp

This is a new feature recently arrived on the note app. If you have sent a message by mistake, or you may have regretted it, you can cancel it within 7 minutes of sending and as long as the recipient has not already read it.

Simply hold down the message and choose “Delete for all”. However, the recipient will be able to know that you have deleted a message by the wording in the sticker that says: “The user has deleted this message”.

4. Secure the most important conversations at the top

If you have favorite contacts with which you often message, do not let these scroll down in the chat list. them at the top simply by holding down on the chosen chat and choose the tack symbol at the top of the menu. From now on you will have that conversation always in the first place in the chat list.

5. Do you want to know the exact moment in which a contact enters online? Here’s how to do

To do this there is WhatDog, an application that will send you a notification when a contact you choose accesses WhatsApp. To allow all this, after installing the app from the Play Store, open it and choose the contact you want to know all the movements. You will see that there will be no access that you won’t know.

Samsung Claimed that LG is not a Valid Opponent

Samsung very much fears Apple, always. The two companies contend many primates and many are the disputes and clashes in court. LG, on the other hand, is underestimated by Samsung, indeed, is not minimally taken into account. This is the weak link.

Samsung no longer considers LG one of its competitors in the mobile industry, according to the comments of a company spokesman during the MWC 2018. He was explaining that the latest Samsung smartphones have less app preinstalled than LG. The same representative stated: “We do not see them as our competitors, but I meant Apple”.

Samsung and Apple have an interesting relationship. In some cases, they met in court, with legal action by the way, for patent infringement. While in other cases, promotional videos have been made public to minimize the products, features and services offered on the other. However, this is often seen as a clash between Android and IOS, it is not just a situation Samsung and Apple.

On the contrary, regarding the Android brand, it has always been speculated that Samsung was fighting to maintain its position as a dominant Android smartphone manufacturer. In this area, as time goes by, LG’s ability to compete with Samsung has diminished. The mobile division of the company struggles to keep up.

According to IDC’s data highlighted by the end of 2017, Samsung has occupied a global market share for smartphones of 21.6%, with Apple in second place with 14.7%. The data remained substantially unchanged from the previous year, with the two companies having a market share of 21.1% and 14.6%, respectively. This is contrary to LG which no longer registers itself as an independent entity in the IDC list since the figures of the South Korean writer are now buried within “others”.

With Samsung and Apple’s joint market share for 2017 (36.3%) only barely changing compared to 2016 (35.7%), the drop in LG in the market did not come from Samsung or Apple. Instead, it would seem that the biggest problem of LG is the rise of Chinese producers (such as Huawei, OPPO and Xiao). One aspect that LG itself has detected when it announced its financial results for 2017.

LG minimized by Samsung that does not fear it absolutely

LG in 2013, was recognized by the IDC as a direct competitor – with its 4.8% that placed the company in fourth place, behind Samsung, Apple and Huawei. For a further comparison, in the same year, Huawei’s market share stood at 4.9%, representing a 0.1% market share compared to LG. Even more revealing was the change that was taking effect up to that point. Since the figures for the market share of 2012 showed that Huawei recorded 4% and LG at 3.6%. Therefore, during the twelve months between 2012 and 2013, LG has actually closed the gap on Huawei by 0.4 percent up to only 0.1 percent.

The result is a year-over-year variation for LG and despite Huawei sees a year-over-year increase in market share of almost 1%. While LG was relegated to the “other” field, Huawei managed to maintain its third position with a market share of 10.4%. A little over a year and at the end of 2014, the image was very different for LG. The company was no longer recognized among the top 5 vendors with Lenovo and Xiao’s that completed the list. Since then, he has struggled to regain the traction of the market he saw until 2014. Although the market has become more accessible, with Samsung and Apple they have seen their market share diminish.

Developed a Laser Technique to Detect Hidden Objects

A Stanford University team (United States) has developed an extremely sensitive laser system for producing hidden object images. It reveals a study published in the journal Nature.

Experts focus on developing applications for self-employed vehicles – which do not require a driver – some of which already have similar systems based on laser technology capable of detecting objects around the car. Other possible utilities include the ability to see through the foliage or to provide rescue units with the ability to find people whose position is inhibited by sight.

The Associate Professor Gordon Wetzstein, from the same American university, and one of the research authors, stated that, even if that kind of technology “sounds like Magic”, it’s “really doable.”

Apparently, the Stanford research group is not the only one in developing laser technology methods to capture images of objects. However, where it achieves considerable progress in this field is the creation of an extremely efficient and effective algorithm for processing the final image of that object.
“A substantial challenge”

David Lindell, co-author of the study, noted that “a substantial challenge” in these techniques is to “find an efficient way to recover the three-dimensional structure of the hidden object.”

During their experiments, scientists installed a laser near a highly sensitive proton detector, which could also record a single particle of light. They aimed at a wall with laser light impulses – invisible to the human eye – bouncing on objects that were hidden behind a corner to bounce in the wall and in the detector.

According to Nature, this process currently lasts from two minutes to an hour, depending on the conditions such as illumination and reflectivity of the hidden object. Based on how well the algorithm works, it is believed that it could be accelerated to make the process almost instantaneous.

But before the system is completely ready, scientists must make it work better with daylight and moving objects, like a bouncing ball or a child running, since until now it works particularly well when they detect Reflective objects, such as road signs.

If this technology was now used in a vehicle, it could easily capture images of objects such as road signs or road signs, but could encounter difficulties in detecting people wearing non-reflective clothing. Wetzstein considered that the study represents “a big step forward” in this field which, he ventured, “I hope that benefit all.”

The Smartphone’s Day: Futuristic Technologies are Knocking at the Door

Smartphones have the days counted. In a short time they will be obsolete and will be replaced by revolutionary technologies. According to the media, although for the next ten years people will not be able to give up the use of his favorite gadgets, one day the smartphone “will die”, just as the fax is already a thing of a distant past.

Entrepreneurs and technology companies such as Elon Musk, Microsoft, Facebook, Amazon and several ambitious start-ups have already started to lay the groundwork for what has been called “the ultimate destruction of smartphones”. And innovations that could replace our iPhone, Samsung and Nokia will be very similar to science-fiction technologies.
Virtual Assistants

Personal assistants like Bixby, already allow us to control all the functions with the voice. The company south has positioned itself as a pioneer of technologies and devices that can be managed with words. According to experts, the next devices will be completely new concepts of human interaction with the technological world.

IPhone X has focused on the introduction of augmented reality in our daily lives. It is not a distant future: all these global changes, more and more perfected, will arrive in the next two years. Because Amazon Echo, Sony PlayStation VR and Apple Watch have a fair success, experts expect these devices to combine together into one interconnected technology ecosystem.

Augmented reality

Microsoft, Facebook, Google are developing augmented reality series. These new technologies will be able to project detailed 3d images directly to our eyes. According to some rumors, even the giant of Cupertino would be working on this same product.

Digital Vision

In the near future, augmented reality will replace the smartphone, television and all other devices with a single screen. And this seems more than logical: Why do we need a device in my pocket if all calls, chats, movies and games can be projected directly into our eyes without distorting reality?


Devices like Amazon Echo and Apple’s AirPods are becoming increasingly popular and necessary in the modern world. In this way, since intelligent artificial systems such as Siri (Apple), Alexa (Amazon), Bixby (Samsung) and Corta (Microsoft) will become even more intelligent, users will use audio data, integrated with video projected over the eyes.


Recently, Elon Musk has inaugurated its new company Neuralink, which will be responsible for the development of a ‘ neural interface ‘, through which users can exchange opinions. The device, according to Musk, will be ready in ten years.
