It looks like Galaxy Note 3 owners on T-Mobile are about to get a sweet treat. According to Samsung's support FAQ for the device, Android 5.0 Lollipop should be rolling out to devices starting today.
In case you've somehow managed to ignore Lollipop and what it brings to the table for the last several months, users should expect to notice some changes to how notifications are handled on the lock screen, a new card UI for the multitasking window, and loads of Material Design cues around the entire device.
In addition to the numerous changes that Lollipop brings, Samsung also notes that the update should bring some improvements to Wi-Fi calling.
It's unclear how wide the rollout is right now, so if your device hasn't received the update yet, just sit tight and it should hit your Note 3 at some point over the next several days.
