No Nostr client on Android hasn't supported NIP-09 Event Deletion yet, AFAIK.

Yes, maybe they need to polish and handle many other things.
Also, imho, probably due to issue of guarantee of event deletion itself. Some relay maybe can ignore the request of event deletion (pretending that event was deleted but only mark it as 'deleted' in database). 😅
Marking a note as deleted is probably good enough since it can communicate the author's intention.
Seems about right. I haven't trued Nozzle but I know amtheyst and nostros dont . well I presume the latter doesn't have jt
