T-Mobile has started seeding the November security patch for the Samsung Galaxy Note 4. The update comes two weeks after we heard the same thing happening for the carrier version of the Galaxy Note5.

While the report covers the Note 4 in particular, the Note Edge does tend to walk hand in hand, so it may be getting it as well. Mind you, the T-Mobile support pages...
