Samsung made history back in 2011 when it unveiled the Galaxy Note — a huge (well, at the time) 5.3" phone with an S Pen stylus included.
According to these sources, Samsung has no current plans to develop a new version of the Note for 2021.
Apple, Google, and even Samsung itself have solid options that retail for hundreds of dollars less than the Note, making the phablet a hard sell no matter how fab it is.
