Soon after announcing the global rollout of Marshmallow for the Galaxy S6 and the Galaxy S6 edge Samsung released the Android 6.0.1 Marshmallow update for the Galaxy Note 5. The update was initially made available to users in Cambodia (SM-N920C) through Samsung Smart Switch but from the looks of it the update isn't without a few issues.
Many of our readers have pointed out that the battery is draining way too fast after the update is installed. Battery drain appears to be an issue that most people who updated to Marshmallow are facing. Others are facing issues with the Gear VR as it's no longer working with the handset after it has been updated. Minor bugs have also been reported. It appears that Samsung still needs time to polish this update so that users no longer face these issues, it hasn't halted the rollout yet so perhaps it might address these issues in an incremental update later. If you've been thinking about flashing this firmware on your Galaxy Note 5 you might want to hold off on that for now.
