OnePlus 3T will receive Android 7.0 Nougat Update in December

Info! The phone will not be included in the beta program though
Great news for those who plan on buying the OnePlus 3T, as the Chinese company recently confirmed the smartphone will receive the highly-anticipated update by the end of the year.

OnePlus 3 owners will be getting a taste of what's to come in November, but the final build will be released in December. Basically, Android 7.0 Nougat will be rolled out to both OnePlus 3 and OnePlus 3T in December, hopefully, around the same time.
However, the OnePlus 3T will not be included in the beta program, which means those who purchase the smartphone won't be getting any community builds like OnePlus 3 users will receive in the coming weeks.

Furthermore, OnePlus confirmed for Android Authority that both its high-end smartphones will share the same update schedule beginning December. So, regardless of which of the two you own, you should be getting updates at the same time (if nothing wrong happens).

OnePlus' pledge to continue to support the OnePlus 3 at the same level as the newly announced OnePlus 3 is gratifying, but let's hope that's going to last until both phones reach end of life status.
One more thing that's worth mentioning is the fact that the OnePlus 3 won't be sold in Europe and the United States going forward.

The Chinese company announced that it will stop production for this particular smartphone, so once the stocks in these regions are depleted they won't be replenished anymore.

If you consider purchasing the OnePlus 3T, then you should know the smartphone will go on sale in the United States on November 22 for $439 (64GB) and $479 (128GB), respectively.

On the other hand, the OnePlus 3T will begin selling in the UK on November 28 for no less than £417.99 ($522 / €487) and £456 ($570 / €532), respectively, via O2 carrier.

If you live in the UK you might be able to get it slightly cheaper directly through OnePlus, which sells it for £399 ($499 /€465) or £439 ($549 / €511).
