Only yesterday, there was a report talking about Samsung phasing out the Galaxy Note 21 series and allowing the Galaxy S21 Ultra to support the company’s S Pen accessory. While we appreciate a member of the Galaxy S family supporting a stylus, it would put a massive dent in Samsung’s overall shipments for the entire calendar year of 2021. Fortunately, the tipster Ice Universe has come forth, implying that such a thing won’t be possible.

While Samsung has been rumored to merge the Galaxy S and Galaxy Note series before, Ice Universe believes the addition of the S Pen for the Galaxy S21 Ultra won’t make Samsung get rid of the Galaxy Note 21 series. He further states that the price and output of the Galaxy Z Fold 3 won’t be enough to cover up the revenue and sales that the Galaxy Note 21 series could potentially bring in, assuming Samsung does get rid of the series.
