Network May be Monitored by an Unknown Third Party Android

Android is one of the most used and popular mobile operating systems in the world. It is full of features. However, there are some features that might make you confused. One of them, the ‘network may be monitored’ warning is not a familiar one for all android users out there.


So what is the reason behind this warning? It is a good sign or bad? In this post we will review the message and what it means and if you need to do something about it. 

Reason Behind the ‘Network may be monitored’ notification

  • User installed certificate issue – More common with older versions 
  • Using proxy or VPN – This is a valid reason to get the warning and should be ok
  • You can prevent this by NOT using a VPN ( easy enough )
  • Or by removing your user-installed certificates

First of all, we will talk about the root cause of this warning. There are a number of possibilities here. So we will describe each of them separately for you.

Reason 1. User-installed Certificate Issue

The number one and the most possible root cause of this warning could be a user-installed certificate. If your phone has one or more user-installed certificates, then your phone would show this warning. Now, what is a user-installed certificate?

Normally, some of the apps you are using on your phone install these certificates in the background. Those certificates allow the apps to track your data usage and send them to those apps. That way they can monitor the encrypted network traffic on your phone.


So whenever some apps have installed such certificates, your phone will notify you about that with that warning. Google has incorporated this warning with the release of the Android KitKat (4.4) version.

If you are using an older Android version, then you will not receive this warning. Now is it bad if some apps monitor your encrypted network data?

Normally, it could actually be bad if your phone’s encrypted data is being monitored. That means some of the apps are in fact malware or virus. And those apps are collecting all the data from your phone. So this is actually a good warning which is used to save you from malware or virus.

Reason 2. Using Proxy or VPN

There are many reasons why you might need to use a VPN service or app. Nowadays, you will find thousands of free VPN apps on the Play Store. However, you might have used proxy settings instead of VPNs back in the day.

A VPN (Virtual Private Network) is used to bypass any network restrictions or to change the location of the user virtually. Let’s say, your country has blocked YouTube. So if you are using your internet connection as usual, you will not be able to visit YouTube.

In this case, you have to use a VPN or proxy service to bypass that block. After you are using a VPN service, you will be able to visit the blocked websites from your location.

Another use of the VPN service or proxy is to bypass geo-restriction on any websites or apps. For example, Netflix doesn’t offer all of its shows worldwide. They have different catalogs for different countries.

Let’s say you want to watch Friends on Netflix. Now, after checking Netflix, you have seen that the show is not available in your location. In this instance, you can use a VPN app to change your location virtually to a country where Friends is available from Netflix. After that, you will be able to watch Friends from your own location without any issues.

When you are using a VPN or proxy service, that particular service or app is actually monitoring and controlling your network traffic. In this case, this is not a harmful thing. Because that app is actually helping you bypass the block or restriction.

However, as it is still monitoring your network, you will receive the warning nevertheless as a safety feature from your android phone. In short, using a VPN or proxy service would also allow your phone to prompt the warning notification. In this case, you should not be alarmed because it is a safety feature.
