Does mycellium and coinomi for android support bech32 addresses for segwit? If they don't would it throw an error if you tried to send it there?
Mycelium doesn't support segwit at all right now. I don't know about Coinomi but it looks like they support Segwit (at least receiving from a segwit address) but not BIP 0173. Since neither support this format, there's no way to generate bc1~ address within the wallet, so no way to send any bitcoin to them using this format.
