A lot of people can’t stand the dedicated Bixby button on Samsung phones because it is easy to accidentally press. And on the Galaxy Note 9, you can’t turn off Bixby. So Jerry from Jerry Rig Everything offers a warranty voiding solution — remove the button and fill the cavity with solid 14k gold, kind of like the way a dentist would fill a tooth cavity with gold. My cheapskate solution: use some black Sugru.
