CEO Steve Ballmer had initially said the update would be hitting smartphones the first week of March.
Spokesman Eric Hautala, the leader of the team behind the updates, says that the update will now be headed to smartphones in the last week of March, but possibly a bit earlier.
For the February update, Microsoft acknowledged that up to 10 percent of customers had issues with the update, especially those with Samsung devices.
This time around, the company will “take some extra time to ensure the update process meets our standards, your standards, and the standards of our partners.”
The March update will add copy/paste, CDMA support, and Marketplace search.
