Samsung began rolling out the Android 5.0.1 Lollipop update last week for the LTE-A version of the Galaxy S4 with the model number GT-I9506. Although the new firmware may not be available for all respective regions at the same time, third-party firmware databases already have the update for download and manual installation.

The new Android 5.0.1 Lollipop firmware, which carries the build number “I9506XXUDOA6,” includes new features and enhancements to the Galaxy S4, such as improved battery life, updated TouchWiz with material design and multi-user profiles.
