Motorola started pushing out the Android 4.4 Kit Kat update for the Motorola Droid Ultra and Droid Maxx back in December, although the update was paused after a number of users reported issues with the release.
Motorola did not officially confirm that the update had been pulled at the time, and now it would appear that it has started rolling out to the Droid Ultra and Droid Maxx Again.
Hopefully this release of Android 4.4 Kit Kat for the Motorola Droid Ultra and Droid Maxx will have fixed the issues that a number of owners of the handsets had been having.
You can check to see if the update is available for your Droid Maxx or Droid Ultra by going to Settings > about Phone > Software update.
If you receive the Android 4.4 Kit Kat update on your Motorola Droid Ultra or Motorola Droid Maxx, leave a comment and let us know if it has fixed the previous issues.
