A component of Android responsible for generating secure random numbers contains critical weaknesses, that render all Android wallets generated to date vulnerable to theft. Because the problem lies with Android itself, this problem will affect you if you have a wallet generated by any Android app, developers wrote in a Bitcoin.org blog post.
Get rid of this:
If you want to get rid of this, key rotation is necessary. This involves generating a new address with a repaired random number generator and then sending all the money in your wallet back to yourself.
“If you use an Android wallet then we strongly recommend you to upgrade to the latest version available in the Play Store as soon as one becomes available.”
“Once your wallet is rotated, you will need to contact anyone who has stored addresses generated by your phone and give them a new one.”
Updates are being generated by the developers for this.
