Firewall for android: Many apps are connected to the Internet unless you know it. Send data, advertising loaded, updated. All that without any notice to you. But you can block them.
The sending and receiving of data in the background is a common thing in Android apps. (Best android firewall without root) They do this to communicate with the authors so that they are equipped with useful data in order to improve the application. This sending data, however, has two major drawbacks: spend resources (data connection and battery) and is endangering your privacy, since the data sent can be captured by third parties.
“There is no problem,” say you, “this data sending is disabled and ready“. It sounds good, but most apps do not allow you to disable the sending of data in the background, since there are no options for this within the application. Some, in fact, not even assumes the use of a connection, but it is used anyway. It is the case of Angry Birds, which loads advertising and send usage statistics without saying anything.
An effective way to isolate an app in the world outside – and thus prevent the connection you use to send or receive data – is to block it with a firewall, which is an app that acts as a wall anti. Android there are many firewalls, but most require root, that is, special administrator permissions. It is not the case of Mobiwol, a firewall that works without root. Let’s see how it works. How to block apps from accessing the internet on Android OS
1. install Mobiwol: NoRoot Firewall: How to block apps from accessing the internet on Android OS
Mobiwol: NoRoot Firewall is a clever application that allows you to block connections from apps without having Android rooted. This is because it acts as a virtual (VPN) connection.
In simple words, Mobiwol is passed through a secure connection, but all filtering made it within your phone. It is as if “catch” the traffic of data until you exit the mobile.
The installation of Mobiwol is fast and secure, and does not require root. Once installed Mobiwol, give the Blue Shield icon to open the firewall settings screen.
2. active Mobiwol: NoRoot Firewall
Press the switch that appears as a first option, and will be shown an Android box asking you if you want to authorize Mobiwol to create a VPN connection. Checkbox and accepts: only in this way the firewall may come into action.
Once activated, you will see appearing a series of notices: mean that Mobiwol is already analyzing traffic and enabling all applications that use the network by default (in other words, already not could browse or receive messages).
3 open the apps list and establishes the basic rules: Best android firewall without root
Control which apps can be connected and which does not carry out from the section of rules (Rules) of Mobiwol. To block a PPP connection is enough to click on the icons of mobile network (four bars) and WiFi connection (the four waves).
Turn off the mobile network for some apps is very useful if you want to force that only they can connect from WiFi networks, an option rarely offered in the options of the apps. Do the reverse (which only use the mobile network) doesn’t make much sense, but you can do it also.
System applications are marked in red, and can be filtered from the top menu. Initially it you are interested in blocking them. From this menu you can also apply two practical shortcuts: disable all wifi connections and mobile connections. Best android firewall without root
4 choose which apps can connect only when you open: Best android firewall without root
One of the most interesting options of Mobiwol is the filter “No background”, which prevents a connection to send data if you are not using it. For example, you can activate this mode for that single WhatsApp to send and receive messages when you have the app open.
Mode “Foreground only” or “No background” is activated by sliding to the right one of the apps in the list of rules. Slip is performed by touching the icon and moving it to the right with a move fast. You will see then that “No background” illuminates.
To undo this mode simply move the application to the left.
5 configure the General options of the firewall: Best android firewall without root
Before leaving Mobiwol to do its work, it should be that you set up some of the same options. The fourth option of Mobiwol, “Settings”, contains some useful options, such as automatic start of the firewall, the acceptance by default of new apps and recording events in the log (log) of the app.
Events are consulted from the third option, “Logs”, and show a lot of interesting information such as the server that connected the app by last time, your IP number and time, as well as the network used (WiFi or mobile) and mode (background or foreground). You can delete individual events by sliding it to the right. Best android firewall without root
Full control of the connection without root! Best android firewall without root: How to block apps from accessing the internet on Android OS
It is already. These are the basic steps that allow you to take full control of the connection from your Android phone to avoid wastes and holes in your privacy. And all this with a free application and without advertising.
For a very similar alternative, I recommend NoRoot Firewall. On the other hand, if you prefer a classic firewall, will have to root your first Android, CyanogenMod Installer procedure that has become very simple.
