Since the new Android 7.0 Nougat is not ready yet, Samsung had to release their Samsung Galaxy Note 7 with the Android 6.0 Marshmallow but the Note 7 users won’t have to worry about it because Samsung has now given them a timeframe as to when the Android 7.0 Nougat update will arrive.
According to Samsung, the Android 7.0 Nougat update will be arriving within the next two to three months. They also added that they will be beta testing the update first before releasing it to their users.
The reason they needed that much time was to make sure the final software is stable. They added that they needed to time to do some extra testing on the software before they roll it out to their users.
Two to three months is really not that long of a wait and their users probably won’t mind waiting for it as long as it does not come with new glitches and bugs.
