Android 7.0 Nougat is now closer to the Samsung Galaxy S6: the smartphone with the new firmware on board has been approved by the Wi-Fi Alliance. That the flagship of 2015 was to receive the update to Android 7.0 Nougat was quite obvious, since Samsung had already published a list of devices that would receive the distribution; the biggest unknown is to know when. Even today we do not have precise information about it, but considering that the Galaxy S6 has passed the Wi-Fi Alliance certification with Android Nougat on board, we can say with certainty that the Samsung Galaxy S6 update is planned soon.
As you can see in the image, the document shows the model SM-G20V, ie the Samsung Galaxy S6 (connected to Verizon), but there is still no news on the Galaxy S6 Edge; that is, the model SM-925. You may receive the update slightly later than the normal version. But of course, we can not provide realistic deadlines for the arrival of Android 7.0 Nougat on the Galaxy S6, and less after what it is taking to reach the Galaxy S7, but we can say that we are one step closer, and if the deadlines are maintained, the wait can last for a few months (maybe two or three), and we can only arm ourselves with a little patience.
Therefore, if we do a review of all the news we have, we can deduce some things. The update of the Samsung Galaxy S6, S6 Edge and S6 Edge Plus to Android Nougat, for example, will arrive in the first half of 2017. From multiple sources of the past, it has also been said that by the end of the first quarter (ie, in March), but as the manufacturer is not very specific when it comes to giving dates, we can not do anything other than assumptions. As for the rest of smartphones launched in 2015, also Galaxy Note 5, Galaxy A3 and A8, Galaxy Tab A with S Pen and Galaxy Tab S2 (LTE).
