You may be already aware that the Nokia Smartphone Security Maintenance Release Summary page lists Build number and details like whether it is just a security patch or firmware update + security patch for a particular device. But now, Nokia Mobile has enhanced the details provided for each Nokia smartphone on the page. It has added new columns for “Security Patch Cadence” and “No guaranteed Security Patch updates after”.

The cadence tells us whether the smartphone is getting monthly or quarterly security updates. No guaranteed security patch update column mentions the time when smartphone’s 3-year promised security update period ends.

In case the security update is not yet available for your Nokia smartphone, you should check the build number of your smartphone and confirm it with the information provided on the page. If the build number for a particular device is mentioned in the list then only it gets the update.
