Here is how I got #citrine to work as both a local relay and as an exposed onion service as outbox relay on my phone. Thanks to nostr:npub1m64hnkh6rs47fd9x6wk2zdtmdj4qkazt734d22d94ery9zzhne5qw9uaks for the idea!

Download Citrine and start as local relay

Open Orbot

Tap more

Tap onion hosted services

Tap user services

Tap +

Add any name to service

Add 4869 to both ports

Hit save

Exit from orbot

Restart orbot by closing out or force close

Restart orbot and connect orbot vpn again

Tap hosted services and copy new onion url

Open #Amethyst and go to relays

Add ws://yournewonionaddress. onion:4869 to outbox relay

Remove any other outbox relay

Hit save
