Samsung, like most other Android OEMs, stops rolling out regular security patch updates to its smartphones after a certain period of time. Since the Galaxy S7 and Galaxy S7 Edge have now been on the market for over three years, the company has decided to stop pushing monthly security patches to the two phones.
The three-year-old Galaxy flagship smartphones will continue to receive security patches but they will be rolled out only once every three months. Samsung Galaxy S7 Active, which came out a few months after the Galaxy S7 and Galaxy S7 Edge, will continue to receive monthly security patch updates for some more time.
In addition to moving the Galaxy S7 and Galaxy S7 Edge to a quarterly schedule, Samsung has confirmed that its latest Galaxy S10 series smartphones will receive Android security patch updates every month. The only two mid-range Galaxy smartphones that will receive monthly security updates are the Galaxy A5 (2017) and Galaxy A8 (2018).
All the new Galaxy A-series and Galaxy M-series models released this year will also receive just one security update every three months. The same goes for the recently launched Galaxy Tab S5e, Galaxy Tab A Plus 8 (2019), and Galaxy Tab A 10.1 (2019) Android tablets.
