The idea of using your phone as your wallet is a great one, but Google Wallet is proving to be a bit of a security nightmare. It looks as though Google has thrown up their hands on rooted devices, at least for now, and put a warning in the Google Wallet app of unsupported devices. The problem is the ability to perform a brute force hack on rooted phones, where a thief could crack the pin code on Google Wallet and proceed to use your phone to make purchases with your credit cards.
Google had issued a statement encouraging rooted users to seriously reconsider using Google Wallet. To make sure everyone received the message, Google has also decided to make this information into a warning message at the top of the app. If you tap the link, you’ll see an explanation of the unsupported device policy, which basically comes down to: “Don’t use this if your phone is rooted”.
While the capability to root your phone is one of the great things about Android, it does take away the control and therefore the responsibility from the carrier, the manufacturer, and Google. We hope that Google is still working on a way to secure Google Wallet on rooted phones, although that is a huge task given that they have no control over a ROM they did not produce.
Let us know in the comments if you’ve received this warning message, and if it has changed your ability to use Google Wallet.
