5 Reasons Why Not To Use Smartphone While Charging

Is that safe?

Is it harming your Smartphone’s battery in some way?

Could it create serious problems in future in your Smartphone?

There’s one simple answer for all the above questions, “Yes”.

Now you wish to know that why am I saying so? You wish to get one appropriate reason for not doing such a thing again?

Heating

Yes heating, that’s the first thing which will happen to your device in case you are using it while plugged in charging. So is it that you think, the heating of your Smartphone doesn’t requires much attention. Well you are wrong, if you are practicing this very often, kindly end it as soon as possible. Getting your Smartphone heated for a prolonged duration will lease to over-heating and you could simply compare and imagine as of what over-heating does to your car in a Layman’s terms. Some of these could probably happen to you:

Lead to leakage of the harmful chemicals in the battery.

Lead to explosion of your Smartphone’s battery.

Could probably stop your phone from turning “ON”.

Bulge in the size of your smartphone’s battery

Charging your phone while using it creates yet another problem, that’s enhancing the size of your phone’s battery. Some of you might have noticed it happening in earlier feature phone/Candy-bar devices. And if you have noticed it then you must be well, aware of what happens next when your Smartphone’s Battery bulges in size. Let me tell you some issues you could face after your phone’s battery swollen:

It might burst, get flammable and so on (i.e. in short – it might hurt you).

It would in-take less charging than before.

With persistent usage, your phone might even stop turning “ON”.

Decrease your smartphone’s total charge capacity

The simplest of all effects would be leading to a decrease in the total battery charge capacity of your Smartphone. Earlier if after a full-charge your Smartphone gave you around 15-18 hours of average playback/usage time, then after the issue created by using your phone while charging; now it might give an average usage time of around 7-8 hours or even below. Leading to which it might decrease to 3-4 hours of average play-back time or even worse if you persist doing this.

Create issue in the smartphone’s battery-charger

Using your phone while charging might even create a pressure on your phone’s Charger, leading to its heat up or total mis-functionality later on. You might even need to buy a new charger afterwards. Well, that initially might not seem a serious issue, but thinking over it you might realize :-

A poor charger will charge your Smartphone slowly and in-efficiently.

Buying a new charger of the same brand and handset wouldn’t be very much economical.

Buying an anonymous local charger afterwards could be even disastrous.

Could end up harming yourself

Well, let’s forget everything written above. You are a rich and have multi-millions in your bank account and could easily dump one Smartphone and buy another one if anything such happens. But wait, could your money bring back you?

If due to any of the above, there’s a mishap with you, Then?

Don’t you believe anything as such could happen? I thought so, that’s why i brought you some of the incidents which you could easily verify on Google.

This Phishing Kit Can Bypass Multi

Security researchers have discovered a wide-reaching phishing campaign that attempts to phish for Microsoft email credentials in order to compromise business accounts. Even worse, it can bypass Multi-Factor Authentication (MFA).

Whilst password managers can be used to create passwords long enough to withstand brute-forcing attacks, MFA-busting techniques are starting to become increasingly common.

The threat actor, in this case, is still on the loose and creating malicious domains at a “relentless” pace.

Phishing for a Catch

Researchers from security firm Zscaler noticed a sharp uptick in the number of phishing attempts taking place across specific industries.

All the phishing attacks, according to the security team, began with an email sent to the victim. Some of the malicious links were located in the email copy, whereas others were loaded into a HTML file.

The attackers have set up a number of new domains, many of which use a classic technique from phishing campaigns called typo-squatting (creating a phishing domain that is a legitimate domain name spelled slightly incorrectly). These attacks are targeting end users in Enterprise-level companies.

Once the malicious code gets to work and a given business account is compromised, that same account is then used to send further phishing emails to other business accounts.

Sectors affected include lending, insurance, accounting, and federal credit unions in the US, Australia, UK and New Zealand.

This threat was ongoing when Zscaler published its report less than 48 hours ago. They tracked the threat actor registering domains.

How Is the Threat Actor Bypassing MFA?

MFA can thwart a lot of phishing campaigns because even if the threat actor manages to obtain a person’s account credentials, they can’t get past the MFA barrier.

The threat actors are using what is called an “Adversary in the Middle” (AiTM) technique to bypass MFA, a function of the phishing kits being used here.

The security community is aware of popular AiTM kits that do the rounds, but Zscaler’s team thinks this is a custom kit.

The kits allow the threat actor to operate a proxy in between the person’s device (or the “client) and the mail server they’re sending requests to (hence “in the middle”).

The proxy means the threat actor can relay all the information between the client and the server.

MFA Weaknesses Reinforce Need for Strong Passwords

Multifactor authentication methods, unfortunately, aren’t as secure as they used to be. Hackers and scammers have developed new techniques that are becoming increasingly common to bypass it.

Sim-swapping — the process of impersonating a victim whilst on the phone to their telephone carrier to essentially swap their number to a SIM to your phone, and thus receive their two-factor authentication text — has been one method that hackers have used to steal cryptocurrency.

MFA’s fragility places a renewed importance on two things: firstly, training all staff in your organization to be able to spot the telltale signs of a phishing campaign and protect themselves, and secondly, having a sufficiently strong first line of defense: long, unique, diverse passwords.

The best way to ensure everyone in your organization has a strong password is with a password manager. Password managers facilitate the creation of not just sufficiently long, but also completely unique passwords for every site your staff have an account on.

Multi-factor authentication methods are not the silver bullet in the world of account security that many thought they once were. So, make sure to use all the resources at your disposal — it’s better to be safe than sorry.

Beginner’s Guide To Universal Approximation Theorem

Introduction

This article puts forth one explanation – the universal approximation theorem.

Let’s start with defining what it is. In simple words, the universal approximation theorem says that neural networks can approximate any function. Now, this is powerful. Because, what this means is that any task that can be thought of as a function computation, can be performed/computed by the neural networks. And almost any task that neural network does today is a function computation – be it language translation, caption generation, speech to text, etc. If you ask, how many layers will be required for any function computation? The answer is only 1.

In this article, we will try and understand why the theorem is true.

WORD OF CAUTION

There are two important facts to be noted.

1. It is important to realize that the word used is approximate. This means that the function computed is not exact. However, this approximation can be improved as the number of computation units i.e. neurons are increased in the layer and it can be fit to the desired accuracy.

2. The function we compute this way are continuous functions. The generality does not hold for discontinuous functions. However, more often than not, continuous functions prove to be a good enough substitute for discontinuous functions, and therefore, the neural networks can work.

Therefore, let’s go ahead and understand this very important theorem. Before jumping to the visual proof though, let us have a look at a perceptron – the basic unit of computation.

PERCEPTRON

A perceptron can be understood as the basic computation unit of neural networks.

 

In the above diagram, inputs xi through xn is multiplied with their respective weights wi through wn . This is what forms the weighted inputs which are then summed up (Σ wi xi). Next, this sum passes through a threshold/activation function which functions as an on/off switch. It allows the neuron to fire if the value of the sum is greater than a certain threshold otherwise the input is inhibited. This is the final value that constitutes the output. Activation functions are also the magical ingredient of non-linearity without which, a perceptron and eventually, the neural network would just be a linear combination of inputs. We will use the activation function sigmoid to understand the basics.

CONVERTING SIGMOID TO STEP FUNCTION

We intend to output 1 for inputs greater than a threshold and 0 for inputs less than the threshold. A sigmoid function does exactly that.

But, there’s a problem- the slope of the sigmoid function. In the output layer, we intend to add up outputs of hidden layer neurons. It will be easier to work with adding integers directly than adding the real numbered outputs of the sigmoid function. Therefore, we will need a step function. Turns out, when applied enough weight, the sigmoid function can be tuned to behave just like a step function. So, to make our lives easier, we will do just that.

The weight 1000 seems a good choice. Adding the bias will help shift the curve to the value of x we intend. Since, we have confirmed for ourselves, from here on in the article, we will treat the outputs from individual neurons in the hidden layer as if by a step function.

USING PERCEPTRON FOR UNDERSTANDING THE PROOF

Let’s start computing functions with a single perceptron in the hidden layer ( hidden layers are the layers except for the input and output layers ).

Let us plot a boolean AND function just to try (it is not related to proof). Both the domain and range of this function are the boolean values {0,1}. In the output ( the bigger circle) the inputs are getting added. This neuron will fire only if both the inputs it receives are 1 otherwise it won’t. By firing, we mean the output is 1, and by not firing we mean, the output is 0.

So, we know how to plot a function. Moving on, let us plot a function using perceptron which outputs 1 on the input being greater than a threshold value T1 and 0 on being less than that. As described in the cases of the previous section, we will have to assign a high weight value and a bias T1 to get the following graph.

Since we have brushed up the basics, let’s move on to understanding the visual proof of the universal approximation theorem. This proof follows closely the visual proof provided by Michael Nilson in his textbook on Neural networks, the link to which is provided in the references section.

What if we want to plot the function wherein 1 is output only when the input value lies between T1 and T2 and in all other cases, the value that is output is 0? For accomplishing this, we will need two perceptrons accepting the same input but with different thresholds as shown here. The network of 2 perceptrons forms an MLP – multi-layer perceptron. Note that the output layer has additive activation yet.

This graph seems like a rectangle. In the face of a continuous function, many rectangles like this can be combined of varying heights to suit the boundary of the function. In terms of architecture, several perceptrons can be stacked together to achieve this function.

This is the approximation of the function we were talking about.

But wait, whatever we have seen till now is only the combination of weighted inputs. We never passed it through the sigmoid function of the final neuron (In the above image, the bigger circle has addition as its function and is never followed by sigmoid). So? It’s easy. Assuming the bias of the final output neuron is 0, we need this hidden layer to calculate σ -1 of the original function. The inverse of a function gives the original value for which the function gave an output. Or in other words, the important property of inverses is:

f(g(x)) = g(f(x)) = x where f(x) is inverse of g(x) ( also denoted by g-1(x) ).

Therefore, σ -1( σ(y) ) = σ ( σ-1(y) ) = y where y is the original function we intend to compute.

So the hidden layers instead compute the inverted function and the final activation inverts it back to the original. The inverted function is still a function and can be approximated using the idea of rectangles described above.

For any continuous function, this approach can be adopted. All the stacked perceptrons form, however, only a single layer in the neural network. The purpose is achieved!

Thus, we establish a visual proof to the universal approximation theorem in two dimensions. This proof stands true for the higher dimensions too, wherein visualization becomes difficult but the concept remains the same.

7 Best Ways To Fix Samsung Galaxy Buds Not Charging Issue

3.4K

Samsung’s Galaxy Buds line of wireless earphones has had plenty of success in the TWS market thanks to their premium design, excellent sound quality, and impressive battery life. But sadly, all of these features matter little if your Galaxy Buds are not even charging. While the reason behind the issue could be many, in this guide, we’ve put together a list of a few troubleshooting tips that should help fix the issue. So, let’s get right to it.

Before We Begin

First, let’s get the basics out of the way. In order to charge your Galaxy buds, you need to be using the included USB cable and a Samsung-approved wall adapter. Additionally, you’ll also need to ensure that the charging cable isn’t damaged in any way.

Next, you can try restarting your Galaxy Buds to see if that works. To do so, place the earbuds into the charging case, and then close the lid. Wait for at least 7 seconds or more, before removing the earbuds from the case. Now try putting them back in again to see if they charge.

If the problem persists even after this, then you can work your way through the troubleshooting tips below to resolve the issue.

1. Ensure That Buds Are Placed Correctly in Case

This may sound simple but it happens to the best of us. If you haven’t placed your earbuds correctly, then the charging pins in the case won’t connect with the earbuds and your Galaxy Buds won’t charge. So, make sure to seat the earbuds in their corresponding slots.

2. Check the Charging Status

If the earbuds are placed correctly, then the battery indicator light located inside the charging case should turn red or green. This indicates that your earbuds are charging correctly. 

But if the charging indicator flashes red, then it means that the charging is blocked due to abnormal temperatures. Now, this can happen due to several reasons. If you’ve been using your earbuds outdoors for an extended period of time or if your case was in direct sunlight for a few hours, then you might see a red LED flashing. Likewise, the charging indicator may also flash red if you’ve accidentally washed your galaxy buds in the washing machine or used them in the rain and the charging pins are still wet.

If that seems to be the case, it’s nothing to worry about. You just have to let your earbuds and charging case cool down (or dry out) for a while before charging them again. 

Similarly, the battery indicator on the front of the charging case will also start blinking red and block the charging if it detects any abnormal temperatures. 

3. Clean Earbuds and Charging Case

One of the most common reasons why your Galaxy Buds will stop charging is if the earbuds’ charging contacts are dirty and can’t connect with the case correctly. To avoid this, you should regularly clean your earbuds and the inside of your charging case with a microfiber cloth.

4. Charge the Case Separately

If the problem persists, then you can try charging your case separately. This should help verify if the issue is with the case or the earbuds themselves.

Use a Samsung-approved wall adapter to charge your case fully. Once charged, place your earbuds inside the charging case to see if they charge.

5. Switch to a Different Charging Method 

If the buds or the case is still not charging, then you can turn to alternative charging methods. Apart from using a USB cable, you can also charge your Galaxy Buds with a wireless charger or a phone that functions as a wireless charger. 

6. Reset Earbuds

If the Galaxy buds not charging issues are limited to one of the earbuds or if you’re facing this issue occasionally, then you can try resetting the earbuds and start afresh. 

Note: Factory resetting the Gear IconX deletes all music stored in the earbuds.

1. Open up the Galaxy Wearable app on your phone and head over to Earbuds settings.

2. Scroll down to tap on Reset. Select Reset when prompted.

7. Inspect Buds and Case for Damages

Lastly, you can check your Galaxy Buds and the charging case for any visual damages. If either of them is damaged in any way, then your Galaxy Buds will not charge. 

If your Galaxy Buds or the charging case is damaged, then you’ll have to visit the nearest Samsung service center to get them fixed or replaced.

Charging Ahead

Probably the last thing you’d want is to face issues while using your favorite Galaxy buds. Hopefully, the above-mentioned solutions have fixed any charging issue you might have been facing with your Galaxy buds and you’re back at jamming to your favorite tunes.
