What is DNS and how does it work?

DNS stands for Domain Name System. It is a system
that allows you to assign readable names to the IP addresses of devices connected to the Internet. In this way, users can access websites, online services, or network resources using easy-to-remember names, such as www.bing.com, rather than long and complex numbers, such as 204.79.197.200.

The way DNS works is based on a hierarchy of servers distributed around the world. They store and update information about names and associated IP addresses. When a user enters a domain name in his browser, the DNS system looks up the server that contains the information about that domain and returns the IP address. Thus, the browser can then establish a connection to the server hosting the requested website and display its content to the user.

How to use AdGuard’s DNS service on your Android phone

The AdGuard DNS is an alternative service to the one offered by our Internet provider or our router. In addition to performing the basic function of resolving domain names, it also filters the requests that are made to advertising and tracking servers. Preventing them from being loaded on our device. Thus, we can surf the Internet without seeing ads or being tracked by third parties.

Follow the steps below to use the AdGuard DNS service:

First step

Go to the Settings application on your Android phone.

Second step

Then go to Network & Internet>Advanced>Private DNS. You can get to this option easier and faster by typing “Private DNS” in the search box of the Settings app.

Third step

After that, once you have selected Private DNS, tap on “Private DNS provider hostname”.

Fourth step

Now, you have to enter the AdGuard DNS address:

dns.adguard.com (to block advertising and tracking).

Fifth step

Finally, click on Save and that’s it!

With these steps, you will have already activated AdGuard DNS on your Android device. And you can enjoy cleaner and safer browsing. Of course, keep in mind that this method only works if you have Android 9 or higher, and that it may not be compatible with some public or private WiFi networks that require specific configuration.

Alternatively, you can activate this DNS from a more intuitive interface with the AdGuard app that you can download from Google Play.

Google Play | AdGuard for Android

Is it safe to use the AdGuard DNS service?

The dns.adguard.com is a public DNS service that protects against tracking, phishing, and malware. According to its website, dns.adguard.com uses encryption and does not keep any logs of user queries. However, as with any DNS service, there is a risk of bugs, unwanted failures, delays, or crashes. It is therefore recommended to
use dns.adguard.com with caution and verify its reliability and performance before relying on it for browsing. Thank you for reading us. Goodbye!

What are multiple users for?

Multiple users are used to give third parties access to your Android device. Perfect if you want to limit the access that these people have to it. In this case, the second user will not be able to access all settings. As long as some of the spaces on the device are restricted by the administrator.

In this way, it is possible to separate the information from the regular user and protect it at all times. At the same time, the second user can use the phone with basic functions. Necessary if you need to make a call, send an e-mail, and do other things that can be done by the account created by the owner of the phone.

The limitation always starts from basic aspects, you will see a more limited desktop, having only a few applications. These include the phone, messages, and email (you need to log in to this service). Depending on what the administrator has configured, you may or may not be limited to other tasks.

How to create multiple users in Android 14

This process may vary slightly depending on the level of customization each phone has. However, it is essentially always the same. It depends on the manufacturer and model of the phone. That is what matters in the end.

Finally, enter a name for the new user and tap the “Done” button. Remember that you can also grant permission to make calls and send SMS. This option is disabled by default.

From this point, you can tap the “switch to new user” button to enter the second space.

How to create a guest account

Another option that Android 14 gives you is the ability to create a guest account. This is the same as a multi-user account, with the only difference being that when the guest finishes his session, the second space is deleted and neither his data nor the applications he has installed are saved. This option is ideal if you want to lend your phone to a third person for a short period and do not want to create a permanent account. It does not take up any space on your device.

To activate the guest account, follow the steps below:

First step

Go to Settings>System>Multiple users.

What is a VPN and what is it for?

Let’s start with a brief review of what a VPN is, for all those people who are not very clear about this concept. VPN stands for Virtual Private Network, which, in simple terms, is a space created with an extension of your local connection that hides your real location and encrypts your data.

In other words, a VPN is a security tool that hides your data from any software that wants to access it. It also alters your IP to make it look like you are connected from somewhere else. The intention is to keep your data safe from any malicious website or person. Opera offers its users a completely free VPN that is already included in its browser.

VPNs have many advantages, however, they are not perfect and there are some not-so-beneficial aspects of using VPNs. We invite you to read on to learn more about these private networks.

How to activate Opera VPN on Android?

The VPN button is within easy reach and you just have to press it to activate it every time you want an extra touch of security in your browsing.

To activate Opera VPN on an Android phone, follow the steps below:

First step

Download and install Opera browser by following the link below:

Google Play | Opera browser with AI

Second step

Then log in to the Opera browser and click on your profile icon in the lower right corner.

Third step

After that, select the option that says VPN.

Fourth step

Once you have activated the VPN for the first time, you can check the settings to make sure they are correct. The next time you want to access these settings, you can press and hold the VPN icon.

Fifth step

Finally, you can choose the virtual location, which defaults to America. You can also set the VPN to be active only for incognito windows. And that’s it!

Just like that, the free VPN of the Opera app on Android will be activated. It’s important to mention that this VPN doesn’t have a lot of customization options, however, it does the main job, that is, protecting your data.

Is it possible to activate a free VPN in Opera GX and Opera Mini?

Opera has several versions of its browsers, each version has a different mission and has different functions, depending on what its users are looking to achieve. The other versions of Opera are Opera GX and Opera Mini, both of which are very good alternatives, but neither has a free VPN integrated. So if you want to be able to have a VPN while using some of these other two versions of Opera, you will have to resort to a third-party VPN. But don’t worry, there are many other free VPNs for Android, you just have to find the one that works best for you. Thanks for reading. Goodbye!

The best option is to delete the Telegram cache using the app itself

The cache is a part of the phone’s internal storage in which certain files are stored. Of a temporary nature generally, they serve to optimize the performance of the apps. However, they can end up being counterproductive if they take up too much space. That is why freeing this memory is key on many occasions, especially in the case of apps that consume as much space as Telegram.

As standard, we know a generic method to clear the cache memory of apps on Android, which is to go to the phone settings. However, Telegram is one of the exceptions in that it is also allowed to empty from the app and more effectively. And the latter is not a saying, since, as you can see, you can delete much more data than from the phone settings.

So that you can achieve your task and delete your Telegram cache, you just have to follow the following steps:

First step

In Telegram, open the drop-down menu on the left. Then enter the “Settings” section.

Second step

After that, go to the “Data and Storage” section.

Third step

Next, now click on “Storage usage”.

Fourth step

Finally, press the “Clear cache” button.

Don’t forget to set limits for Telegram

After you already know how to clear the cache manually in Telegram. Perhaps it is also interesting to set a limit so that it does not occupy more than a certain amount of space. So you will not have to be constantly aware of the memory occupied by the application.

To achieve this, you must return to the same menu as before (Data and storage). But instead of just hitting the “Clear Cache” button. You should slide down and until you see the “Maximum cache size” option. The convenient thing to do would be to move the bar and set it to 5 GB, which is the minimum you can set. Another setting that may benefit you is to disable the automatic downloading of media files. This way, when you receive a lot of files they will not be downloaded automatically. And you can manually choose which files you want to download. This setting can also be found in the “Data and Storage” section.

Once you have followed the steps in this article. It is advisable to keep checking the cache space occupied by Telegram from time to time and you can delete it if you see it necessary. However, you can now rest easy knowing that it will not get out of control. At most, it will take up 5 GB, which is already quite a lot in itself. Thanks for reading. Goodbye!

Blocking the permanent mobile data connection

Wireless connections are an essential part of smartphones, especially after the progressive popularization of apps connected at all times. Android searches for a tower to connect to, tries to locate known WiFi networks and, on top of that, performs both tasks constantly and by default. Restricting this operation will have positive effects on battery saving without wasting more than a few minutes each day.

Increasing battery life is possible with two hidden settings on your Android that will help you.

In the Developer Options, several settings allow you to get some more autonomy. And two of these options are practical: “Mobile data always active” and “Wi-Fi scan throttling”. Both are intended to reduce the time away from an active Internet connection, but they can be switched off without reducing the usage experience too much. We find this highly recommended.

Here’s how to disable both network features from Developer Options:

First step

To begin with, it is essential to enable the “Developer options”. To do this, go to the settings of your Android. Then find the “About phone” section. Next, locate the “Build number” and press that option 7 times until you see a message saying “You are now a developer”. This activates the “Developer options”. There is a possibility that you will have to authorize unlocking your phone.

Second step

Then go back to the main “Settings” menu and go to the “System” section to locate the new “Developer options”. For each brand of phone, this may vary: they are usually located under “System”.

Third step

After that, swipe down in the Developer Options menu until you find the “Wi-Fi scan throttling” setting and enable it.

Fourth step

Finally, just look for the “Mobile data always active” option and turn it off. And that’s it!

Conclusion

By configuring these two functions of WiFi and mobile connectivity in the background your Android device will stop searching for networks constantly and, when connected to a known WiFi, it will disable mobile data so as not to waste resources when they are unnecessary (you can also completely disconnect the WiFi and activate it only when you are under your known networks). In return, it may take a few seconds longer than usual for your phone to connect to the Internet when you leave the WiFi coverage, nothing that would be problematic. Remember to try these options and let us know your experience in the comments. Thanks for reading us. Goodbye!

How to tell if your Android phone was infected with Spyware

Now that you know what Spyware is and why it can be so harmful. We can now explain how you can tell if your Android phone was infected by Spyware. The good news is that it’s not a difficult thing to do. It’s all a matter of knowing the signs that your phone is infected:

• Your phone gets very hot.
• The apps you use every day run slower than normal and so does the operating system.
• Your battery and mobile data last less than usual.
• You get a lot of pop-up messages.
• You have installed apps that you do not remember installed. Pay special attention to apps with the following names: mSpy, XNSPY, CocoSpy, or Hoverwatch.

The last condition does not necessarily have to be met because this type of malware can disappear from the main screen to run in the background. Also, it does not necessarily have to have those particular names.

How to remove Spyware on Android

In case you have the signs that we have mentioned to you, your mobile is likely infected with spyware. In that case, you should do the following:

First step

Press the power button on your phone until you get the menu to turn it off or restart it.

Second step

Then press and hold on the screen the option to turn off your smartphone until you see the “Safe mode” option. When you do that your phone will reboot.

On Xiaomi devices, the process is a bit different. Just turn off your device, Once it has turned on before the MIUI logo appears, press the volume down button.

Third step

After that, the next thing is to go to the “Settings” section and then enter “Applications”. If you see any apps that you don’t remember installing, don’t hesitate to delete them. When you are done, restart your mobile to exit Safe Mode.

Remove administrator privileges from unknown apps

Sometimes, Spyware can be installed on your smartphone with administrator privileges. In this way, it has access to the operating system settings and even to the deletion of data. If you want to find out if you have Spyware with administrator privileges and also stop it from running, here’s what you need to do:

• Go to the “Settings” section, then to “Security & Privacy” and then to “Other security settings”.
• There you will see several options, but the one you should enter is one called “Administrator Apps”.
• The last thing is to disable administrator privileges for any unknown app.

If there is any app that you have doubts about, search Google for information about that application to confirm if it is a system app or Spyware. We also recommend that you put your phone back into Safe Mode to try to remove that application. Remember to keep your phone updated with the latest version of the operating system. Which usually include security patches. Thanks for reading. Goodbye!

Types of folders on your Android device

Possibly, you are used to seeing only one type of folder, but this only happens on the computer. On the phone, there are several types, but we will focus on two main ones, the ones that contain files and the ones that appear in your menus to organize the apps. Folders or directories are used in computing to organize the data contained within the computer. A good example of this would be the disorder that would exist if they did not exist, imagine having all your photos along with the boot files of your computer. This methodology also allows for optimized operation when running processes. In general, there is only one folder, however, due to their functionality, location, and environment, they are classified separately. Another reason to separate them is the procedure necessary for their creation, which I detail below.

Create folders for your apps

If you are one of those who can’t conceive of clutter in your apps, then this method is for you. The idea is to structure folders according to the type of applications they will contain. For example, you can add all your social networks in one folder, payment options in another, and messaging systems in a separate one.

The steps to achieve this type of folder are very simple. But just in case, I show you step-by-step how to achieve it.

First step

Enter the area where the apps are located, usually on the home screen or in the application drawer, if you have it enabled.

Second step

Then to create the folder, it is necessary to start with two apps. Later we can add more apps. Simply hold down on the first app and drag it to the second app.

Third step

After that, we will simply drop it. Automatically, the two apps will appear together in a folder. The default name is “Folder”.

Create folders for files

In case you want to have a series of folders to organize your files. It is also possible to do this. To do this, we will need a file manager, these come pre-installed on various phone models. And in other cases, we can simply download it directly from Google Play.

In this opportunity, I will assume that you have one installed on your phone and there is no need to look for a new one. The steps you must follow are as follows:

First step

Access the file manager of your Android phone. There will be no major change between one app and another, you can change the interface a little bit.

Second step

Then go to the internal storage section. Thanks to this, you will be able to decide where to place your new directory.

Third step

After that, click on the three vertically aligned dots in the upper right corner. Among the menu of options that will appear, you should click on “Create folder”.

Fourth step

Next, you must enter the name of the folder you want to create. The new folder will appear and you will only need to enter the content you want. You can even configure some apps to save their files in this folder.

In case you want to delete a folder, hold your finger on the folder for a few seconds until a series of icons appear at the bottom of the screen. You must click on “Delete”. As you can see, creating a folder is a simple process, and ideal knowledge for new users. Also useful for those more advanced users who want to have more order in the storage of their device. Thanks for reading. Goodbye!
