Samsung has started pushing out the February security update to some of its Galaxy J series handsets. Specifically, the Galaxy J1 2016, Galaxy J3 2016, and Galaxy J1 Ace Neo are getting the latest security patch.
The update arrives as build number J120FNXXU1AQB1, J320MUBU0AQB1, and J111MUBU0AQB2 for these handsets, respectively.
