The Android 5.0 Lollipop update is gaining momentum across the globe, but many eager users in the U.S. are getting impatient waiting for their specific device to receive an OTA notification telling them they're about to get their Lollipop. Here's the latest.

As we indicated last week, a document supposedly leaked from Sprint had several devices on the list for an update rolling out at near-future release date. This included the LG G3 and HTC One M8. Unfortunately, according to Business Insider, there haven't been any clear confirmations of LG devices getting updates on Sprint yet, but there's some good news as well.

The news site reports that HTC One M8 owners are getting the Android 5.0 Lollipop update on Sprint -- and also HTC One M8's on T-Mobile. Meanwhile, LG G3 owners using AT&T as their wireless carrier of choice will rejoice, as Android L is hitting their devices this week as well.

Meanwhile, we know the Samsung Galaxy S5 had an early release date for the Android 5.0 update, and it seems to be confirmed that Verizon is the first to launch it in the U.S.

But in addition, according to GottaBeMobile, Samsung Galaxy Note 4 owners should (finally) begin to anticipate a release date for Lollipop in the U.S. as well, as the Android update is quickly sweeping through international models and Poland.

If the Galaxy Note 4's OTA update follows the same pattern as Samsung's Android 5.0 rollout for the Galaxy S5, a fresh download of Android 5.0.1 with an upgraded TouchWiz could be coming to Galaxy Note 4 devices in the U.S. right soon after it's spotted in in the wild in Korea, Spain and a few other regions.

However, any Android 5.0 Lollipop update rollout's release date is dependent on U.S. carriers finishing their respective testing and approval process. And if Android Lollipop's pitiful 1.6 percent global adoption rate three months in -- plus the near-Sasquatch sighting-level rarity of any OTA Lollipop update releases for brand new flagship smartphones in the U.S. being spotted in the wild -- tells us anything, it's that Android L is a particularly cumbersome update to roll out.

And the big four wireless carriers are certainly taking their time.
