Samsung recently made some changes to the list of devices for monthly security updates. 4 mobile phones released in 2017 were deleted from the support list.
They are Galaxy J3 Pop, Galaxy A3 2017, Galaxy A5. 2017, Galaxy A7 2017. Pointed, that Samsung also deleted the Galaxy Fold 5G, but it should have been deleted by mistake, and it has now been added back.
Samsung has moved the Galaxy A8 2018 from the monthly update plan to the quarterly update list; Galaxy A8s has been moved to the other regular’ patch list.
If there is no security update, then the possibility of discovering vulnerabilities in the OS version running on the device will increase.
The 4 mobile phones that Samsung deleted this time have all been discontinued, and their holdings are not high, so Samsung made the decision to close supporting them.
