Samsung is still the world’s largest smartphone manufacturer by volume of shipments. Although in the past its customized layer on top of Android has been strongly criticized, the company has made an effort in recent years and its new interface named One UI based on Android Pie is the best we’ve seen.
Both smartphones have received the security patch of March and from now on they will do it every three months (instead of once a month as it has been until now).
On the other hand, the Galaxy S10+ / S10 / S10e, Galaxy S7 Active, Galaxy S8 / S8 + / S8 Active, Galaxy S9 / S9 +, Galaxy Note8, Galaxy Note 9, Galaxy A5 (2017) and Galaxy A8 (2018) will continue to receive monthly updates .
Samsung has excluded the Galaxy S7 / S7 edge from the list of devices that will receive Android Pie but, at least, it will continue to receive security updates for longer.
