How do I set up & use hotspot?

Go to Settings > Network & Internet > Hotspot & tethering > Wi-Fi hotspot > Toggle to "On" position.

From this point, you will need to create a password and if you like, you can rename your hotspot network to locate it easier.

Once you have done that, and Hotspot is on, turn on "Wifi" on the other device you want to connect. Search for your Hotspot network, input your password, and you will be connected.
