Samsung's Note phones usually have generously sized displays to accommodate the S Pen stylus and stand out as a productivity machine. Rumors report that the newest iteration could have the biggest screen yet at 6.66 inches, according to tech blog site igeekphone. Compare that to the Note 9, which has a 6.4-inch screen.

This doesn't necessarily mean the overall footprint of the phone will get bigger though. As bezels get thinner and phone-makers are getting more resourceful about relocating the front-facing camera, the Note 10 could as well be the same physical size as the Note 9, but still have a bigger display.
