Android Lollipop is the latest version of Android from Google which was released a few months ago but unfortunately, Google had to batter multiple bugs after the initial release of the OS. Nonetheless, Android Lollipop is the most desired OS this year (and a part of last year) and I hope everyone out there is eagerly waiting for a Lollipop build to roll out to their device.

While most OEMs are struggling to roll out the Lollipop devices to their flagship models, Samsung is successfully pushing Lollipop builds to its old and new devices. We’ve seen many Samsung device to get the Lollipop update and now it’s turning for the Galaxy S4 LTE-A users to taste the awesome Lollipop OS on their device. However, the S4 LTE-A users might feel a little left out while most of its siblings got the Lollipop love a week ago. But, we say it’s better late than never.
