Also waiting for Note 8 successor
I am also waiting..
I bought a Tab S 8.4" for my daughter for her studies overseas, the size is perfect, & you can hold with one hand. The screen is no-horse-run and with 3Gb and octa-core, it is incredibly fast. I even surrender my Belkin mobile keyboard for her. It works perfectly fine with the Tab S.
So, can we expect a Galaxy Note S 8.4"? Age is catching up, even my current Note 3 screen is a little hard to see clearly nowadays. I use the S-pen very often (started with Note 1).
With a Note S 8.4" LTE, I can carry around and perhaps buy a Galaxy K-zoom to complete my mobile possession!
