The Marshmallow update rollout for the Galaxy Note Edge has begun for all 3 major carriers in Korea. We’re seeing the Marshmallow builds for model no. SM-N915K (KT Corporation), SM-N915L (LG Plus) and SM-N915S (SK Telecom), each having build no. of N915KKTU2DPE2, N915LKLU2DPD8 and N915SKSU2DPD8 respectively.
The international Galaxy Note Edge had already received the Marshmallow update, though the US variants of the Note Edge are yet to be granted the Android 6.0 wishes.
To download the Marshmallow OTA update on your Galaxy Note Edge in Korea, go to Settings, About device, and then check for it under the system updates section.
BTW, it could take 3-4 weeks for the OTA to appear on your device as the whole update process is carried out in phases, but if you want the update now, be sure to check out our firmware page provided below.
The above page is updated with latest firmwares as and when they become available, making it easy for you to update or fix your device easily.
We don’t have the full changelog with us right now, but because it’s Marshmallow, we’d totally recommend you to install it.
