That 120 Hz screen refreshes so much faster, but comes off about the same speed as before (slowly and painfully).

Comparing this to the Note10+ display, there's no obvious indication that this one has the faster refresh rate. It does look a bit more streamlined though—Samsung managed to consolidate down to a single ribbon cable, simplifying repairs a bit.

On-board silicon includes:

Qualcomm QBT2000 3D Sonic Sensor controller

Samsung S6SY79AX Touchscreen Controller

Winbond W25Q80EWUXIE 8 Mb Serial NOR Flash

Appropriately, the codename for this "space zoom" phone is.... Hubble. As we all know, the Hubble space telescope worked perfectly at launch, never needing a single repair.
