At our site we frequently remember the importance of always keeping up to date. Leaving notifications of pending updates can be very counterproductive, especially when we are facing security patches. Samsung has a strict policy so that its terminals are protected , although not all models receive the same flow of these types of updates.

We see very frequently how security breaches are common. Mobile phones are a frequent target of cybercriminals who can exploit any of these breaches for malicious purposes. For this reason, you will see that your Samsung mobile frequently receives updates, whose only detail in the change report is a security update.
Messages and quarterly updates
To avoid all these problems, Samsung releases monthly and quarterly security updates on many terminals in its catalog. These updates include patches for security issues related to the Android operating system published by Google, as well as patches for specific Samsung security issues . In addition, within each security patch, Samsung can resolve dozens of different vulnerabilities detected, both by its own tools and by external collaborations. Samsung classifies all security vulnerabilities as Critical, High or Moderate, depending on the danger that each one of them may pose.

To consider
As detailed by Samsung itself, it should be borne in mind that in some cases, regular operating system updates can cause delays in the security update plan . However, operating system updates will include updated security patches when they are released. Likewise, security patches also depend on specific regions and models.
At other times, it is the chip vendor that offers specific patches, which may not be included in the monthly security update package, but will be integrated by Samsung in subsequent update packages. Likewise, the company has been publishing the registry of security patches month by month for years. In them, you can see all the vulnerabilities found and their level.
