There are ways to help you find out that your smartphone has become the object of surveillance and eavesdropping.
An Android smartphone can be eavesdropped through malicious programs. Therefore, experts never tire of emphasizing that you should never install unofficial, suspicious applications.
In order to protect your Android smartphone from eavesdropping, you should not open suspicious emails, messages, SMS. In no case should you go to a hyper-link that causes suspicion.
Otherwise, the risks of installing malicious software on a smartphone increase.
Another way to listen to a smartphone – call interception due to a vulnerability in the global telecommunications protocol SS7.
There are some clear signs that a smartphone is being tapped. So, for example, you can notice that the gadget began to discharge too quickly. This can be caused by an app running in the background and potentially tracking your activities.
Clicks, beeps, and other interference during phone calls can also indicate that the conversation is being intercepted or recorded by third parties.
It is also necessary to be alert if the Android smartphone heats up even when it is not being used or it is not on the charger.
Frequent reboots or turning off the smartphone – this may indicate the operation of malicious software.
In order to check whether your Android is not being eavesdropped, you can use special codes.
The code #21# will help you find out if calls are being forwarded and text messages to another number. The code #62# will allow you to find out to which number calls and text messages are forwarded when there is no connection.
Another code ##002# will allow you to disable the forwarding of calls and text messages.
