There seems to b something odd going on with the Google Wallet app. After a the app’s recent update, it seems to be requesting for root access. The initial report says that nothing has changed with the Google Wallet that would need root access.
Some suggested that Google is doing this to check if a phone is rooted or not, so that they can deny access. However, the app has worked for some users. whether they grant access to it or not.
Another odd thing is that, other users were not able to use Google Wallet after allowing it root access, but were able to use it once they disallowed it. Nothing in the changelog suggests that Google has made this change.
