10 Common Smartphone Mistakes That Expose You To Security Risks

10 Common Smartphone Mistakes That Expose You To Security Risks 1

Smartphones have unarguably evolved into an irreplaceable part of our daily lives . Think of  how many times do you use your phone  in a day? Quite a lot times I guess . With such an important device that’s a vital part of our daily lives, I must say I’m quite shocked and surprised by the mistakes and errors people make on smartphones and unnecessarily expose themselves to security risks.

Here’s a quick list of the most common mistakes people make

1.Not Locking Your Phone

It may seem like stress to type in your screen lock password or draw your unlock pattern any time you want to use your phone but this is one  the easiest ways to prevent unauthorized access and/or use of your phone.

Hackers can crack any screen lock security with some given time, but this step gives you  a basic form of first level security that will prevent most people from accessing your phone.

The best type of security code for smartphones are  PINs or  more preferably passwords .

Screen patterns  can easily be hacked. Set your
phone to lock the screen after one minute of being idle.

2.Not Turning On The AntiTheft Feature On Your Phone On

Not all smartphones come with this but with this option, the phone has a second layer of security. I once sold a Tecno H3 to one of my friends, I forgot that I set the AntiTheft feature on. Even after he flashed the phone, the AntiTheft feature was still in place. He couldn’t use the phone until I unlocked it. One good thing about the anti theft feature is that once your SIM is removed, the app will anonymously send an SMS with the next sim card that’s slotted in the phone to the number that you selected as security numbers.

Once your phone gets stolen, you’ve got nothing to worry about. Except of course your pictures..

3.Joining Public Wi-Fi Networks

Some people are fond of doing this, joining any Wi-Fi network they see forgetting that this is also a major security risk. Information and data transmitted over public Wi-Fi networks are visible to anybody on the network if they know how to view it.

Hackers can easily steal your details  and remotely access your smartphone. If you have to connect to a public Wi-Fi network, make sure you’re using a VPN like Droid VPN or TUNNEL BEAR VPN . VPN stands for Virtual Private Network and is a method to connect to websites securely . Otherwise, use your mobile data network.

4.Not Having An Antivirus Installed

Some people will go to great lengths to make sure they have the latest and most up-to-date antivirus for their PC but the protection for their smartphone is Zero .  85% of  most smartphones do not have security or Antivirus apps pre-installed  . Only a number of smartphone users  install antivirus and other security software.

I recommend  Bitdefender , AVG and Avast to secure your Android phone .

By installing an antivirus on your smartphone, you also avoid transferring a virus to your computer via USB which is a common problem these days.

Some damaged memory cards may have the shortcut virus that replicates itself many times in a PC as shortcuts to programs but this can be fixed with Smadav PC Antivirus.

5.Forgetting or Refusing To Install  Updates

Most Smartphone manufacturers use software updates to improve functionality and to fix security gaps. In general, you should accept updates to your phone’s operating system as soon as you are notified. If you don’t have enough data try subscribing and updating your phone.

The same goes with applications on your phone. Make it a habit to regularly update the software running on your smartphone.

6.Not Verifying Your Apps Before Installing
Only few people verify applications before they download and install them. By verification , I mean  carrying out some basic research before installing an app.

Many smartphone users download and install applications that come packaged with malware that gives a remote hacker root access.

Most recently users have been hit with the Quadrooter and Gooligan Malwares.

Quadrooter constantly shows pop-up ads and installs apps without permission. All this can be avoided.

I think where the problem lies is mainly with Android phones because of  the relaxed rules required to host an app in the Play Store. iPhone users are safer due to Apple’s closed wall policy.

7.Clicking On Any Link You See
It’s generally more difficult to spot a fake login page on a smartphone than on a computer. Furthermore, shortened URLs make it extremely difficult to detect illegitimate addresses. The best way to stay secure is to avoid clicking on suspicious links sent via SMS or instant messaging apps.

8.Jailbreaking or Rooting
I know many  hard-core rooters and jailbreakers pe will probably bash me for this one. However, the fact remains  that non-rooted Android devices and non-jailbroken iPhones have a certain level of security that limits the amount of access a user has to vital parts of the phone’s operating system. Jailbreaking or rooting gives you access to hidden system settings that allows you to do much more with your phone.

Everything comes with a price and the price you pay for that is greater security risk.

I’m not saying you should avoid rooting your phone. All I am saying is that if you choose to do that, make sure you know what you are doing.

9.Not Switching Off Bluetooth

You’ve probably not heard of the terms bluejacking , bluebugging or bluesnarfing. These are  situations where  hackers can gain access to your phone using your Bluetooth connection.

Using this method, the hacker only needs to be at just about 30 feet away from you and you’ll never  ever know what just hit you. Within a matter of seconds, a Bluesnarfer can steal details such as confidential information and even login data to various sites. So, unless you are transferring or receiving a file,  for God’s sake switch off your Bluetooth connection.

10.Storing Sensitive Data On Your Phone
I don’t  understood  people  store ATM card PINs, bank online passwords, sensitive images/videos and other such sensitive data on their phones. If your phone is stolen, it wouldn’t take a geek to know  that a four digit number stored as a phone contact is a PIN to one of your accounts. With more analysis , a clever crook can mess up your life.

Make sure you check yourself and make sure you’re not doing any of these things to save yourself from security risks.

Tecno Camon i4 – Full Specs And Cheapest Price

Published

on

Tecno Camon i4

Tecno just launched a new device into the Camon lineup the Tecno Camon i4 and the device comes with very impressive specifications and a very good price in this post I’ll be looking at the specs of the Tecno Camon i4.

Tecno Camon i4

The TECNO CAMON i4 ships with a mid-range MediaTek Helio A22 processor for the 2GB / 3GB RAM version and a MediaTek Helio P22 processor for the 4GB RAM version and 32GB / 64GB  of internal storage.

The Camon i4 runs on Android 9.0 with HiOS 4.6 on top, keeping the lights on is a 3500mAh battery with support for fast charging.

I do hope the fast charging isn’t the same as the Xcharge on the Tecno Spark 2 because that means it’s not actually fast charge. Tecno deserves this shirt on that note

Design And Display

I’m quite impressed with the fact that Tecno decided to go with the dewdrop notch on this device instead of that lousy Apple-like rectangular notch. This one is quite similar to the one on the Samsung M20 and I’d say it’s not bad at all considering the fact that they’ve been giving us phones with notches since the release of the Camon 11 Pro.

You basically get a 6.2-inch IPS Capacitive display with an 81.3% screen-to-body ratio. It’s not something you would call totally bezelless as there’s still as small chin below the device.

Camera 

The Camera is one of the selling points of this device as the smartphone’s triple camera has a 13MP, 8MP, and 2MP lens combination, which means you would get an impressive performance while taking photos and recording videos at 1080p. The secondary camera at the front is a 16-MP lens and great for selfies. You also get better quality when calling someone via video so cheers to the Snapchat and Instagram Slay Queens.

How Multiple Cameras Work On Android And iOS Smartphones 5

How multiple cameras work on smartphones have always been a question on the minds of most people and 2019 is the year of multiple cameras and many if not all smartphone brands have released phones with multiple cameras. You’ve probably seen the Nokia 9 Pureview with 5 cameras and the Huawei P30 Pro that comes with 4 cameras  (40MP + 20MP +12MP +TOF Camera) and 50x optical zoom.

How Multiple Cameras Work

These two devices come with crazy specifications but I won’t go into that right now, maybe in another post.

However, have you ever tried covering the main camera of your device with a dual camera?

If you haven’t, try doing that right now.

You’ll notice you are actually blocking the whole camera. That leaves the question – What do the secondary cameras do and how do they work.

How Multiple Cameras Work

Now I want you to understand this. Most OEMs have other uses of their secondary camera other than the ones I’m going to mention below. These are just the basic functions of the secondary camera.

The secondary camera improves the overall clarity of the image with the help of a “Monochrome” feature. The secondary camera only records the black and white version of the image. With the help of the Monochrome sensor, the primary camera measures how much light is coming from the point of focus.

Previously (with the exception of the Google Pixel 3), the primary camera in smartphones normally handled the measurement so there was a very high possibility of losing some detail while measuring light intensity since it would still need to work on the color filtering.

So this extra burden is handled by the second camera which takes care of that area. Combining the monochrome image which has detailed information about the light and sharpness with the colored image that was captured by the primary camera will produce a rich and detailed image.

In some phones, the secondary camera acts as the zoom lens. Huawei uses their cameras on the P30 Pro a bit differently but going into the entire details might end up making this post a bit lengthy and a bit boring for people who aren’t hardcore techies so I’d try to keep this balanced. However, if you’d like to see that in another post do let me know in the comments.

So that’s basically how multiple cameras work on smartphones
