The Samsung Galaxy Note9 earns a 4 out of 10 on our repairability scale (10 is the easiest to repair):

This Note's components are more modular than ever, thanks to subtle changes to the USB-C hardware, headphone jack, and the S Pen dock's flex cable.

The only screws used are standard Phillips screws.

You can replace the battery if you're determined—two extremely stubborn glue barriers make it unnecessarily difficult.

To service any component you must first painstakingly un-glue (and later re-glue) the glass rear panel.

All-too-common display repairs require replacing the entire chassis or tediously separating the gluey cracked glass.
