I feel happy that all our Nokia phones are part of Android One program and get regular monthly update.
But when such critical issue is fixed in update why HMD ensures the all Nokia will get the update under Pure-secure and up-to-date policy.
In addition, why HMD release Info-graphic (for critical patch only) so Nokia customers will able to know when their model will get secure from critical vulnerability. (Suggestion)
For model TA-1083, TA-1021 and TA-1032 this PNG bug will get fixed in February 2019 update? @HMD_Laura
