Recap on Why Android 5.0 Lollipop update got delayed for Galaxy Note 4:

Usually Samsung releases new OS updates to current flagship phones and later to older models, but to everyone's surprise, it released v5.0 Lollipop OS first to 2013 model - Galaxy Note 3 instead of the new Note 4 in late January. This apparently raised a lot of questions and became fodder for rumour mills to churn out numerous speculations.

Later it was learnt that the delay in Lollipop release for Galaxy Note 4 was due to Oculus VR, who had hit road-block while tweaking the Android OS source kernel to make the flagship Samsung phablet compatible with the company's Gear Virtual Reality (VR) device.

[For the uninitiated, Gear VR is a wireless virtual reality head-set developed by Samsung in collaboration with Oculus Rift. It was launched along with Galaxy Note 4 in September last year. More information, HERE]

Last month, the company finally fixed the issue and began rolling out the update to Galaxy Note 4 in Poland. Soon, Samsung is expected to expand the Android Lollipop OS release programme to other major hubs including India soon.
