Google announced that it will also include the December security patch in the January patch for some Pixel 3 users who did not receive the December security patch.

Google Pixel smartphones get monthly security updates first in the first week of each month. However, some users of the Pixel 3 series have not been patched until December.

The Google Pixel support community has been posting posts of complaints from Google Fi users and T-Mobile users alleging that they haven’t received updates since November.

Google announced on its official MadeMedGoogle account (@MadebyGoogle) that users who did not receive the December update will receive the December update as well as the January update.

Google did not comment on the reason for the update delay.
