I installed wallet back in May and I used it many times without issue. Then in the last couple of weeks I've noticed that when I go to use it, I turn the screen on and then nothing. It won't recognize the reader. If I fire up the wallet app then the transaction goes through perfectly fine. This has happened several times in a row at different locations without one incident of successful recognition of the reader. I was planning to to do an uninstall/re-install but I figured I'd check to see if anyone else has experienced this problem and knows a sure solution to it.
