6 Best Android Firewall Apps to Block Harmful Viruses

These days a lot of hacking groups are active and our personal data is at stake. Thankfully, Android comes with some of the best security features there are. If that is not enough, you can easily download and install one of the best firewall apps for Android to keep your device safe from any person that wants to attack your phone.

Chances are, you won’t need a firewall app if you are using the apps from Google Play store because they are already verified by Google. In case that you want to install an APK or apps that are not available on the Google Play store, from an external source, one of the benefits of a firewall app is that it allows you to see if those apps want to communicate without you knowing it.

  1. Billa, Kinda new to this Android OS on my new RCA 11 Maven Pro Tablet w/detachable keyboard. How familiar are you with majicJack and their “app?” for use on an android os? Also, i am told that the Tablet is merely a larger version of an i-phone, like Samsung, etc. I have had neither and now I have this tablet. What about anti-v, firewall, etc. for it? And of course, the manual has almost nothing to say about these matters. Can I use it to make and receive phone calls, texting, skype, etc. How easy are these to “hack” into and/or peep and intrude? Just let me know but please, not too technical of terminology. Thanks. Will.Harrison.Jr.

    1. Hi, Will! Welcome to Android! Our writers typically just focus on creating content, but I’m Megan, editor here at Joy of Android, and I’m happy to help you out. You obviously have a lot of questions, which is great because it will help you learn faster. Instead of answering your questions individually, I’m going to link you to some Joy of Android posts that will provide you with far more information than I could in a single comment and will probably provide you with information about things you didn’t even know about in the first place!

      First things first, here are a couple posts with more general information for Android beginners:
      Things a New Android User Might Be Afraid to Ask, but Needs to Know
      5 Great Android Apps for Absolute Beginners. Now let’s look at some of your specific questions.

      I personally used Magic Jack for the first time several years ago as a way to make calls online when I didn’t have a smart phone and I was in a country where Skype is blocked. I also know people who use Magic Jack as their exclusive phone provider, and others who use it for an inexpensive second or temporary phone line. All I’ve heard is glowing reviews. As for their Android app, you can find some information about Magic Jack, as well as some similar services, through this guide: How To Make Free International Calls On Android to Chat All Day.

      It is more or less accurate to say that a tablet is more or less a larger version of a smart phone. Online calling and messaging apps allow for use of these services as long as you have an internet connection. That will need to be through a wifi connection unless you have a data plan for your tablet. If you don’t have a data plan for your tablet and want one, your cell service provider should be able to help you set one up. The apps in the link on international calling above should all work for online calling, and here’s a guide to apps that you can use for messaging: 5 Best Internet Texting Apps for Android. And yes, you can absolutely use Skype, too!

      Last, let’s talk about security. Since you’ve commented on our post about firewall apps, it seems pretty safe to assume that this is a pretty big concern for you, and it should be! It’s important to take your security seriously, but it’s also not too difficult. The most important thing to know is that your data is much more likely to be compromised because someone gets their hands on your device, not because someone hacks it, so be sure to never leave your tablet unattended where someone else could access it, and be sure to use a secure lock screen just in case.

      Hacking is more commonly a problem when someone who has your sensitive information, like your insurance company, bank, or credit card company, has a breach in security, which there’s not really anything you can do to prevent, but it can also be a problem if you accidentally download something unsafe onto your phone. Fortunately, there’s plenty you can do to prevent this. It sounds like you’re going to be a pretty casual Android user, so there’s probably no reason for you to download apps from anywhere but the Google Play Store. Google takes a lot of care to keep dangerous downloads out of the Play Store, while third party app stores can be full of dangerous malware disguised as apps. Just in case, you’ll also want to have at least an anti-virus app, though a firewall app, like any of the ones listed above, is also helpful. Here’s a round up of some of the leading anti-virus apps: Make Your Choice for the Best Antivirus App for Android to Keep Your Personal Data Safe. We also have individual reviews on a lot of the anti-virus apps, so be sure to use our search bar to find other posts about any that you’re interested in. You may also want to take a look at these anti-malware apps: Anti-Malware Apps for Android. Finally, always be careful when you download anything onto your mobile device. This guide can help you download safely: How to Keep Your Android Safe While Downloading Files (7 Tips) and this device can keep you safe while opening downloads, just in case something bad slipped through: 3 Easy Ways To Safely Open Downloads on Android.

      Now, I know that was a lot of information, so please feel free to ask if you need some more explanation, or if you just think of more questions! Thanks for using Joy of Android as your source for Android related information and, once again, welcome to Android!
