A new patent reportedly accepted by an Indian authority may kick off speculation about the Note 10's successor. It shows a case design with a cut-out that matches the usual placement of an S Pen, and that suggests a rear-camera module similar to that of the Note 10 Lite. However, it has no scope for a 3.5mm jack, which is a feature of the new mid-ranger.

Unfortunate, but that patent also shows either lack of the Bixby button, or lack of a power button... but lack of the Bixby button seems more likely.
