You're right, it's there and I didn't see it.  All's well.

Dear Mycelium devs, two questions / suggestions:

1. Any chance you can lower the default tx fee to 0.00001 BTC per 1000 bytes? This has actually been the default fee setting in Bitcoin Core already since v0.9. And the very commonly used Android Bitcoin Wallet by Andreas Schildbach has been using this fee setting as well for quite some time, always works fine (just very rarely, a tx might take two or three blocks to confirm, but never leads to any problems whatsoever).
The thing is, here in Europe, bank transfers are free. So when comparing Bitcoin to old fashioned banking, the 0.0001 BTC tx fee (approximately 0.03 euros) may actually seem quite expensive in comparison. Especially for microtransactions (e.g. a €1 donation) a 3% fee is relatively expensive. It would make a better case for Bitcoin usage if you apply the new default fee in Breadwallet too.

2. Dealing with crippled WiFi: in order to push transactions, do you actually connect to Bitcoin nodes directly (i.e. you need port 8333 access for most nodes) or can Mycelium also use a web stub that works through port 80? The problem is, we quite often experience problems with public WiFi networks that have been limited, e.g. only ports for http(s) and email being accessible. Or even worse, open WiFi networks (in stores or public places) that have no password, but require a one-time login page to accept terms before allowing full internet access. When this happens, people's phones *appear* to have internet access, but any http request will redirect them to a login page. Now when trying to send a Bitcoin payment it won't work (saying "Broadcasting transaction..." forever), thus giving the false impression that Bitcoin is having problems, rather than their WiFi / internet connection being crippled.
It would be great if you can 1. push txs through port 80 as well (through external API sites, there's plenty available) if you're not doing so already, and 2. perhaps check if Mycelium has a working connection, and if not, warn the user "Your internet connection seems to be restricted, perhaps you need to login to your WiFi network?" This may avoid a lot of unnecessary confusion.

Chances are that we will wipe and reset the score (star rating) when we switch, too, since, again, it doesn't really mean anything at this point.

Does that mean that every traders score will be reset?

Just the star ratings, not the trading information.

1. Any chance you can lower the default tx fee to 0.00001 BTC per 1000 bytes? This has actually been the default fee setting in Bitcoin Core already since v0.9.

Already implemented in beta of version 2.1. Should have been released already, but we keep adding little tweaks that people have been requesting, which kept pushing it back due to extra testing. If you want to join beta and try out all the new features, go here https://plus.google.com/u/0/communities/102264813364583686576 Just make sure you have a backup of your keys before using it. We haven't had any issues with beta wallets screwing up balances (since we use testnet first), but just in case.

It would be great if you can 1. push txs through port 80 as well (through external API sites, there's plenty available) if you're not doing so already, and 2. perhaps check if Mycelium has a working connection, and if not, warn the user "Your internet connection seems to be restricted, perhaps you need to login to your WiFi network?" This may avoid a lot of unnecessary confusion.

Since we use our own custom nodes, I think we use port 443 for connections, instead of the standard port 8333 that bitcoin nodes use. Since it's a custom node thing, I don't know if we would be able to push transactions to anywhere, but we'll look into it. As for internet connection, I think we already check for it when you try to sync your wallet balances, and it briefly pops up to let you know if your internet connection isn't working. What we REALLY need to do is implement BIP70 to be able to push signed transactions directly to the receiver, using either the internet, or other means like Bluetooth or NFC. But there are so many other things to add....

Good work! I'm very pleased.

On my iPhone 5s QR code (on receive screen) is covered with numpad.



Anyways, thank you very much for iOS version!

[trasla]

As far as I know, you can tap outside of the keyboard to hide it on iOS. Cannot check it, though, since I don't own an iPhone.

[minimalB]

Yes, you indeed can, but it's an unnecessary extra step. Minor UI improvement could easily solve this mini problem.

-Import watch-only bip32/bip44 public master keys

We don't even have that in our Android version yet. We're still deciding how to implement it, and will probably release it when we release support for HD wallets in Entropy.

-Export an encrypted backup to icloud, or dropbox or box.net

That probably won't happen, since we now support 12 word style seeds that must be written down. Encrypted backups have caused issues, with people losing their backups, or losing their passwords.

Good news on the iDevices release!

I don't have one to test, but it seems some functions like Local Trader are not supported yet. Is this a Apple T&C issue? Or just a delay?

Just a delay. The iOS devs haven't gotten to it yet

v2.1.0 has been released to https://github.com/mycelium-com/wallet , https://mycelium.com/bitcoinwallet , beta channel and very soon also staggered release to general channel.

Changenotes from 2.0 to 2.1:

*) Optimized output selector that omits dust from transactions and makes fees smaller on average
*) Fallback geocoder
*) New NFC function to push payment request
*) Show total amount of coins in accounts view
*) Customizable fees
*) Pin reset function with a 7 days enforced delay
*) Fix crash if you don't have a flash on your device
*) Preview of secret sharing import/cold storage - Compatibility for Mycelium Entropy
*) Ability to delete Mycelium Local Trader accounts and trade sessions
*) Bugfix for synchronizing single address accounts with a zero balance: now allows you to view the history
*) OKHttp - connection pooling for faster syncing (preparation for orchid integration)
*) Button for each account to manually resync (in case of possible malleabilty, or otherwise getting strange sync edge cases)
*) Removed permissions no longer needed due to version upgrades (account, SDcard)
*) Now requires Android 4.0 - 2.2 is explicitly no longer supported.

can you explain what you're planning there?

Preparing for fully integrated TOR support, with no more need for third party apps, and to have the mycelium app connect directly to hidden service servers.

Certainly works for me. Sync is down from ~17 seconds to about 3.

Also, thanks for the change in fees.

Sorry for letting you wait so long, glad your problem is finally resolved!

We had multiple crash reports from Nexus 6 devices, with out of memory.

Since we don't own any N6 yet, it would be great to hear how it is possible to reproduce a crash.

This morning, when I open my Mycelium.. it show that I have 0 BTC! It was shocking to know my 0.01 BTC went missing..
Phew, after sometime.. it become 0.01 BTC again.. Hmm.. what's wrong with it? I am afraid this happen another time and I make another backup..

When that happens, rescan.
Click on the account so the blue bar appears on top, click the three dots on the right, and hit rescan.
That will bring your account up to date.
Assuming you use the HD wallet then the only backup you need is your original 12 word list.
