Right now, there are numerous trials across Europe (and other places too, of course) based in large part on the fallout of the EncoChat hack. https://en.wikipedia.org/wiki/EncroChat
At least in Sweden (where I can follow the discussions easily) the defence are raising questions about the legality and to some extent, the validity of the evidence from EncroChat. So far it seems seems the courts are accepting the evidence.
Also, it is quite amusing to read the EncroChat logs from some of these trials. The user names selected and the messages sent sometimes shows very bad opsec.
