Hello, I would like to hear the experience and information of others who have experience with listening to a mobile phone. What form can the interception be traced to ... Are there any warning signals? I've been watching a call drop out for some time, mostly still with one person. The first few minutes of the call are fine, and after a while they start to lose the other person and the call seems to be partially interrupted and there is definitely a "sneer" that makes the call impossible. .
