Last night Microsoft announced the updates to Samsung phones are resuming:
Starting today, we plan to resume rolling out the February update to Samsung phones. Meanwhile, we’re continuing to dispatch the update to other Windows Phone models. As has been the case, the software patch is being sent out on a rolling schedule. You’ll see a message on your phone when it’s available.
During the past week the engineering team has pinpointed and fixed problems that were preventing a small percentage of Windows Phones from installing the February software patch. We apologize again for the delay and continue looking for ways to improve the update process.
