Recently Samsung launched a security update for the Galaxy S10 family which included the March backup to the mobile phone. Boring information has now been received.
It seems that the latest update does much of it. After Samsung started sending the latest update, many Galaxy S10 owners have heard that their phones have overheated. The problem seems to apply to Galaxy S10e and S10 but not S10 +.
It's still to see what Samsung is doing to the problem.
