While Samsung has not said anything about its plans to make Android 5.0 Lollipop available for the Galaxy Note 4, a tweet from the company earlier this week fueled speculation that the latest version of the flagship phablet could receive the new firmware sooner than expected.

Other than tweeting about the Galaxy Note 4’s Quad HD display, Samsung added an image of lollipops on the device’s screen, which many believe to be hint that Android 5.0 Lollipop update for the Note 4 is on its way.

The Android 5.0 Lollipop, the latest version of Google’s mobile operating system, is also expected to be released for the Samsung Galaxy S5 sometime in December, SamMobile reported Friday, adding that the firmware update could take a month or so from its initial rollout to reaches all compatible devices worldwide.

Introduced at the Google I/O conference in June as Android L, the Android 5.0 Lollipop is the biggest update to the OS since Android 4.0 Ice Cream Sandwich. The update brings a new material design user interface and updated notification functions. Other key features of the firmware include lock screen notifications, multi-user support for phones, 64-bit processor support and file sharing through Android Beam to name a few.

Although the new Android version is still more than a month away, SamMobile recently posted a video, which showed a test build of Android 5.0 Lollipop running on a Galaxy S5.  Here’s the video:
