Hi BitcoinZ Community!

I start to mine the Btcz couple days ago. I really like the coin, the projects and the community. I'm using the Btcz Wallet (Android) to receive payments from the mining pool. It works fine for receiving funds.
But, looks like there is some ISSUE when I SEND funds to other wallets.

Today, I donate 1000 btcz to our community wallet address t1fHHnAXxoPWGY77sG5Zw2sFfGUTpW6BcSZ, here is txid: 3d44daa4e715579381492da6b07af9adc892f8b4ee00faf198bc1b864496467c
when I check the detail I see 1000 btcz was sent to the above address as expected, at mean time, 7 btcz was sent to another wallet. It's very weird. So, I check other two small 'send' I have done before from the same Android wallet, and here is what I found:

1. 6bf1674c445bf0acce327b73b506d4278e0804720ce3056df129a429171418aa during first or second day of mining, I want to test the send function of the wallet and donate 100 btcz to the above community wallet,
turns out 208 btcz was sent to another wallet in that transaction.

2. 341c1fc1de83068e9e0dfec9dbcf88bbf79f275d727aa18f50fe0f5042559720     I want to test my new paper wallet and sent 100 btcz, turns out 72 btcz was sent to another wallet in that transaction.

So, each SEND transaction from the Btcz Wallet (Android) generated another send action I don't know. Hope someone from DEV team can take a look. Reliable wallet is the key for our success.

BTCZ Rocks!
