Feature request:
If the wallet has multiple keys (addresses) and they have labels then please show the label of the receiving address in the transaction history instead of the sending address. The sending addresses are pretty much meaningless (to me at least and I guess to most other people too), I would rather like to see which of my own addresses has just received a payment. Currently there is no way to determine that information easily, even if I select the transaction details from the menu it won't show me the label, it will only show me the address (which I can't remember, that's why I have given them names in the first place).
Schildbach wallet suffers from the same problem (it has address labels but doesn't actually use them for anything and its author doesn't seem to be interested in fixing it), that's why I moved 5 Keys from Schildbach to Mycelium today, hoping it would work as expected but now I'm a little bit disappointed to see the exact same problem here :-(

There is still the private key export function in the menu of the keys view. Thus exported keys are not encrypted. There is also the reverse function, key import, activated by the new key icon.
if you like to view the private key directly (without the 2-factor pdf) one of the best ways to secure the key is to take a photo with a old-fashioned (digital) camera and print it. if you like analog, you need to develop it yourself though ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) I wonder if you could get light sensitive paper and lay the phone upside-down on top of it for a few minutes ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) I have printed the backup directly from the phone before.

Bug report: When attempting to send from this address: https://blockchain.info/address/1K3bMZ7SvkzoGZTYD5EpYPKbN8PPQKqidGwhich currently contains 2.48345024 BTC and hitting the "max" button to send everything it will only allow me to send 1.91515024 BTC Any attempt to enter any larger amount will be denied with "insufficient funds to pay fee". This address contains only a dozen outputs and a fee of 0.5683 BTC (over 400 Euro!) seems a bit high to me. Edit: is it maybe the unusual pay-to-pubkey format of some of the unspent outputs? These were generated by Schildbach when It moved coins internally between 2 addresses (this is a key that was formerly used in my Schildbach wallet and was imported into Mycelium). If this is the case then you need to fix it so that it can use these types of outputs as transaction inputs. You will need a different type of signature script for these inputs, only the signature and not the pubkey because the pubkey will come from the output script, see wiki: https://en.bitcoin.it/wiki/Script#Standard_Generation_Transaction_.28pay-to-pubkey.29Edit2: This will most likely happen more often when people start importing keys from Schildbach. These pay-to-pubkey transactions are generated by Schildbach when it does its emergency transactions, when funds are sent to an old address that was flagged as insecure (due to the Android bug) it will immediately sweep the funds into a new secure address and it will use pay-to-pubkey for it. All these pay-to-pubkey transactions you can see arriving in my above address result from this.

Can you ask how blockchain.info does it?
piuk very seldomly responds. My guess is that they go for a happy-go-lucky approach. If you search for stuck transactions and blockchain.info you get quite a few hits.

Mycelium does not support using pubkey outputs. It was never a priority as next to nobody is using it these days. So what you see in the UI is the maximum you can send from the address while paying a normal sizes fee. The rest will be left untouched. This does not mean that the rest will be the fee, but I agree that it is a bit unclear. If you click OK (without Send) you will see the fee that it calculates. All this said, we probably should support pubkey outputs. In 2 1/5 years of BitcoinSpinner / Mycelium pubkey outputs have never been requested.

Hi, newbie mycelium question: I have two identical, ultra cheap chinese phones running 4.X. Factory reset, no sim and wifi turned off. Only added app is mycelium. I want to use them as (identical) dedicated offline cold storage devices and send one to my brother as backup. I'm just running tests at the moment.
When I start mycelium up, I have the option to backup and export/share my private key as an encrypted PDF. But if I don't want to go online, how can I get that PDF from the phone to a printer? I would prefer to save the PDF directly to the SD card (after writing down the password) and then take the SD card to my laptop and print the PDF. And then import the key into the second phone. Is that possible? I only see online options for sharing. I don't really want to expose the private key and take a photo.
Sorry if I've missed this in another discussion. Note that I'm also in china right now with no vpn so I can't watch the instruction videos on youtube.

we will be adding features to support this. meanwhile, you can - either install a "share to sd card" app
- or take a photo of the private key using a plain old digicam.
- or create a private key using any other means offline and scan it.

If those ultra cheap phones does have it, you could share the PDF via bluetooth to another device (the other phone, for example) without going online or installing any app.

Good suggestion. And they do have BT. I just walked into a China mobile store and the phones were on special for $27. Dual SIM, 4" screen, and as it turns out BT too. I've never used a Bluetooth point to point connection before but I'll try it tomorrow. To be honest I think Bluetooth may be the shittiest protocol ever developed so I generally avoid it, but for this purpose it should be fine.

I was having same problem. I just exported key and imported it to blockchain.info and sent from there. Edit: No, my problem was different. I had sent payment, it showed but didn't actually send it.

one of the server nodes got stuck at block 280136 due to a corrupt bitcoind database (36 blocks behind), catching up now, so when you read this everything should be synchronized

Is something stuck again? Got a tx in Mycelium with 0 confirmations after an hour. Blockchain.info shows 3 confirmations.
