I thought Mycelium was meant to be a good mobile wallet. Why do you think it's a piece of junk?
I made the mistake of trying Mycelium's iOS wallet. Horror story. I sent bitcoins and it was showing "sending" below the bitcoin amount for nearly 2 hours. There was a transaction ID on the app but it didn't exist on the blockchain. When I tried to derive the raw transaction, I was getting errors. I tried everything. Even used the recovery phrase on another wallet to try to salvage the coins.
The transaction finally went through after 2 hours. It was probably queued on their server. Or they probably send the bitcoins in batches. Never again. I uninstalled it.
