Google's latest version of Android, 5.0 Lollipop, has slowly been making its rounds across some top-tier Android devices, but Samsung's popular Galaxy lineup has yet to receive even a lick. Recent leaks, however, indicate that Samsung is doing its best to bring Lollipop to its flagships as soon as possible.

Recent images leaked onto Twitter (courtesy of @DDDorresteijn) show Samsung's latest powerhouse release in the mobile market, the Galaxy Note 4 phablet, running Android 5.0 Lollipop. The images do little more than show the lock screen and notifications, and while it's almost impossible to determine the veracity of the pictures, they look in line with Samsung's style. Other than that, there's not much else on the Galaxy Note 4 front.

As far as the Samsung Galaxy S5 goes, there's a little more. Thanks to the ever-hardworking Android community over at XDA Developers, a beta firmware is now available for download for the Sprint Galaxy S5 model SM-G900P. The update is a test build, so expect some bugs to reveal their glaring heads. It seems that calls, SMS and other phone functions work, but the poster does state that he has not tested everything just yet. The firmware is also a full restore, meaning it will wipe all of the data off the phone (make sure to back up!), something that will not happen with the final release. As usual, it's best to wait for an official rollout if you haven't flashed Android devices before.

Samsung-centric SamMobile seems to have gotten their hands on a Galaxy S5 Android 5.0 Lollipop build, and while the website isn't releasing it to the public due to its infant nature, they do state that the build improves performance across the board -- something widely expected. SamMobile is also in the midst of testing out Lollipop for the Galaxy S4 Google Play edition and has reported that Samsung is also hammering out Lollipop for the Galaxy Note 3.

Other smartphone manufacturers like Motorola, LG and HTC are all aggressively pushing out Android 5.0 to their flagships, and Samsung has been suffering a slump, making Samsung's Android 5.0 rollouts crucial to customer satisfaction. The general volume of evidence points to Samsung working hard at making sure it isn't looked at as the lumbering, aging giant, so expect a release in the coming months. Some in the technosphere believe the firmwares could begin hitting the airwaves before 2015 is over, but as usual, it's best not to get hopes too high. Android updates have taken months to land on Samsung devices due to catering them to the TouchWiz interface underneath.
