After releasing the Android Marshmallow to marquee phones Galaxy S6 series and Note 5, Samsung has deployed the new OS update to the former flagship phablet, Galaxy Note 4, in India.

Android 6.0.1 Marshmallow update is around 1.41GB in size and has been made available through OTA (Over-The-Air), SamMobile reported.

Since the firmware is more than 1GB, Galaxy Note 4 owners are advised to download it via Wi-Fi for smooth installation.
