Samsung used to be know for their timely update but now they update security patch and fix bugs quarterly. Releasing 1 update in 4 month. Thats look like the work of third class brand.
As per your query, we want to inform you that in some cases regular OS upgrades may cause delays to planned security updates. However, you can rest assured the OS upgrades will include up-to-date security patches when delivered.
We are doing our best to deliver the security patches, the delivery time of security patches may vary depending on the regions and models.
