Leading smartphone maker Samsung has reportedly rolled out the new Android Marshmallow to the flagship Galaxy Note 4 in Europe.

Technology blog NapiDroid has confirmed that the new Android Marshmallow (build number: N910FXXU1DOL3X) has been released to Galaxy Note 4 (SM-N910F) in Hungary.

Though the news brings joy to Samsung fans, it is a bit strange considering the fact that the company is yet to deploy the new update to current flagship models -- Galaxy S6 and Galaxy Note 5 series.

There is no official word on why the software release process got delayed for the marquee phones but there is a possibility that Samsung engineers might have found bugs during the test-run of the new software. Earlier this year, Samsung faced similar dilemma and released Android 5.0 Lollipop to Note 3 ahead of Note 4 owing to glitch found in the firmware's source code.
