Hello Dicedicexd,
Thank you for reaching out to Apple Support Communities.
These steps may help:
"Wi-Fi
On the device that you want to connect to, go to Settings > Cellular > Personal Hotspot or Settings > Personal Hotspot and make sure that it's on. Then verify the Wi-Fi password and name of the phone. Stay on this screen until you’ve connected your other device to the Wi-Fi network.
On the device that you want to connect, go to Settings > Wi-Fi and look for your iPhone or iPad in the list. Then tap the Wi-Fi network to join. If asked, enter the password for your Personal Hotspot.
Bluetooth
To make sure that your iPhone or iPad is discoverable, go to Settings > Bluetooth and stay on that screen. Then on your Mac, follow the manufacturer directions to set up a Bluetooth connection. Learn more about using Personal Hotspot with Bluetooth.
Personal Hotspot supports Bluetooth connections with Mac and other third-party devices. To connect another iOS device, use Bluetooth."

If the issue persists, can you provide a few more details? Is your Samsung able to connect to any other devices? Are you seeing any errors or alerts? Also, has this ever worked previously?
Cheers!
