GitHub - Mercurygram/Mercurygram: Unofficial, FOSS-friendly fork of the original Telegram client for Android
Yes this is a Telegram client and yes it will break the Lemmy's downvote world record but I still find this one very nice and "actively" maintained. There are not many good Telegram FOSS forks without Google integrations and similar stuff out there.
