I have used mycelium for a long time, I used to really like it, more and more I think it's crap.
I am looking into electrum for long term storage but would be interested to hear any other recommendations for mobile wallets, preferably ones that let YOU hold the private keys and don't rely on any 3rd parties to function...

What happened was, I deposited approx. $400 into my mycelium wallet,
I saw it arrive and confirm.
Then I sent out $145, again this arrived and confirmed.
But then when I sent $500 back to my mycelium wallet, the change or remainder from the the original $400 deposit disappeared. (approx $200 just gone)

I have reloaded the account multiple times. I have even restored the account using the seed words on a separate device, (android phone) nothing.

What is strange is that, now when I look back at transactions, the initial $400 deposit shows up in the history, but the sending out of the $145 does not.

If anyone has any insight into this issue it would be appreciated. I can see the change wallet where the ~$200 ended up. It's still there. I am using mycelium on an android device. I only used a QR code to send out that initial withdrawal of $145.

EDIT: I don't know if it's pertinent but I should add that I can see in the transaction history all the recent deposits and withdrawals and my balance does not add up. This all occurred a number of hours ago and I pay high transaction fees on mycelium so all transactions have been confirmed.
