***FAQS***

Why does Mobiwol No Root Firewall show as if using a VPN connection?

This is superficial. We've used technology available to us from within the VPN packaging module offered by Android to be able to gain visibility to your applications' network activities and apply firewall rules without having to ask for root permissions like other Android Firewall apps. However, no actual VPN connection is being made, no data is being sent externally by our application, and we do not tamper with the security of your personal data, so you can continue using your apps with peace of mind, and confidence that you will not end up with a higher than usual data bill at the end of the month.

———————-

Why Can't I accept the VPN Prompt?

You will need to select the checkbox first and then the button becomes enabled. If you are having problems selecting the checkbox, it is likely that you have another app that creates an overlay on the active screen that is preventing you from selecting the checkbox.

These two threads explain the problem further and give some examples of apps that do this-

———————-

Why does Mobiwol top the data usage chart?

It’s an illusion. Mobiwol uses your device’s VPN package to create a firewall. As every data packet sent or received by your apps passes through the VPN, all the incoming and outgoing data traffic gets attributed to Mobiwol.

The good part, however, is that Mobiwol now comes with its own Data Usage feature which allows you to check data usage for each app. To view the usage, choose Data Usage from the home screen.

How does it improve my internet connection?
If you have a high-speed Internet connection but notice that your web browsing speed isn’t all that it’s cracked up to be, then your problem may lie in the DNS. By optimizing your device's DNS records, you can find the fastest routes for your data packets to take when traveling the Internet. It won’t boost to your download/upload speed, but in some cases it can result in quite a noticeable improvement in web browsing time.

At times, you may experience slow hiccups while trying to use the internet from your device. Sometimes, these problems can be attributed to your provider's DNS settings because your ISP may not always have the best DNS server speeds.

Your default DNS server directly affects how fast you’ll be able to connect to a website. So choosing the fastest server according to your location will help speed up browsing.

With DNS Changer, you can find the fastest DNS server and connect to it with just one touch!

“Karma Firewall app lets you take control back of your phone and block internet traffic to and from specific apps. This is a simple yet powerful firewall with an easy to use intuitive GUI which allows you to protect your sensitive data.

Ever wondered why lots of apps that have no need for Internet access require Internet Permissions? Its usually either to display adverts or send your sensitive data back to servers in USA, China or Russia. Karma Firewall can block this traffic and protect your personal data. You do not need any technical skills to use, no complicated IP Addressing, Ports, Packet Filtering etc. Simply select the apps you want to block, and you are protected.

Karma FW app requires no internet permissions! No data or information about you or your phone will ever be sent back to servers in China, Russia or the USA. In fact the app only requires the start on boot permission. This is fully configurable. If you tell the app not to start on boot, it will not start on boot. No other firewall on the market requires so few permissions. No Internet permissions means our Karma FW itself cannot communicate anywhere. Karma FW does NOT require root. Karma FW is the safest, most trusted Firewall on the Google Play App Store.”
