SamMobile claims to be privy to exclusive information that points to a quad-camera set-up for the upcoming addition to the Samsung Galaxy Note line. This is the same number of rear-panel sensors found in the Galaxy S10's 5G variant. In addition, it is possible that the OEM may change its phablet's naming scheme this year.

I certainly hope none of this is true, the fourth camera is a useless ToF and the crucial main module wasn't upgraded. Samsung's putting themselves in a very risky situation stalling the upgrades when even HMD (Foxconn) could bring something groundbreaking (12.4 stops DR in a phone) into the scene.
