Thanks BurtW for the explanation. I really thought that having a backup of the private keys would be enough whatever the transactions, and as you confirm it is the fact.
However, you're right about the hypothesis of the problem: I used two different addresses, and I only took a backup of private keys for the older one.
So that is my mistake :-(
Topic: Android Bitcoin Wallet Backup missing some bitcoins (Read 2320 times)
Well, what i understand is that if you do a backup, it’s on the coins in the wallet (at that time). So you will not be able to get back the coins that you got after the backup, that’s why you need to do backups all the time.
Kind of, well sort of...The question is: did you create any new addresses that you used to receive the BTC after you did the backup? A backup is the backup of your private keys. All transactions using the private keys in your backup will be there. However, if you:
1) Create a few Bitcoin addresses
2) Backup the private keys for those adddresses
3) Make some more Bitcoin addresses
4) Fail to backup the new private keys
5) Lose the phone
Then you will have all the BTC that were sent to the addresses you created before the backup but you will lose forever the BTC sent to the addresses you created after the backup - since you failed to back up the private keys.
In the future use a deterministic wallet such as Wallet32 for Android. You only have to backup the seed used for the wallet once, then you never have to worry about backups every again since every Bitcoin address and every change address used is calculated from the one seed that you back up when you create the wallet.

I tried the reset blockchain function. however it didn't bring my bitcoins back.
Looks like every transaction that happened after the backup got lost.

If you see your coins which you have bought in March you should also see others.
Try "reset blockchain" function from the "options" menu.
I had similar problem and it does help.
It will take a while (xx min).. and after that you should see your coins .
For example if you will make a wallet backup today it will generate keys for +100 transactions. (Correct me if I am wrong) If you made more than 100 transactions your coins might get lost. This is why on the bottom of the main screen of Bitcoin Wallet for Android there is info about "you need to backup your wallet".

Hi,
I started using Android bitcoin wallet in march.
Back then I made some transactions (bough some bitcoins) and did a backup, that I put on a separate drive.
Later, this summer I bought more bitcoins that added up to the ones bough in march.
And then I has a phone crash and had to do a factory reset.
Then I reinstall Bitcoin Wallet and imported the backup I made in march.
Problem: It only contains the bitcoins I bought in march, the bitcoins bought in June are missing.
Did I need to run a new backup after each time I bough some bitcoin?
More importantly, is there any way to recover the bitcoins I bough in June??
Thanks, I hope someone can help!
