The Note 7 comes with Android Marshmallow out of the box with new features and hardware upgrades including the Iris Scanner, which enable users to unlock the phone by just starring at the phone.

Now, another good news for Note 7 users. The Android 7 (nougat) will be available for Note 7 sooner (in 2-3 months) as hinted by Samsung.

Galaxy S7 and S7 edge might also get the Android 7 at similar time.
