In my OP I remarked that the vendor gave me a new device in exchange but
I hope that possibly someone could easily give me a good plausible
on what I described, noting that the phenomenon seems to be quite
I don't err, since googling with e.g. "mobile phones making calls by
itself" results in
fairly sizable numbers of similar cases.
It is my suspicion that hacking could be a very probable cause. As
layman I have had
namely the experience (three times!) of my PCs being hacked. But the
occurrence of hacking on mobile phones (almost with the purchase of a
and a new SIM card) very much surprised me.
BTW, in the meantime I think I have found a good literature that seems
to indicate that the
communications over the cellular networks are indeed very highly
vulnerable to intrusions
by hackers. In the section of electronics of a public library I saw by
pure chance a paper:
R. Devi et al., Implementation of Intrusion Detection System using
System for 5G Wireless Communication Network, Int. J. Electronics and
Vol. 74 (2017) pp.94-106. I don't have knowledge to understand the
content of that paper.
However I believe that its title alone seems to solidly support my
of the very high vulnerability of mobile phones with respect to hacking.
kindly correct me, in case I am wrong with this thought of mine.
