I have a force close when i try to buy a application :/
"Error purchasing: lab result: Null data in IAB result (reponse -1002: Bad reponse received)"
I can buy nothing ...
That's a known issue of the fingerprint app. It will be solved in a later update. Until that, you can avoid this problem by deleting all fingerprint samples. After you finished your purchase, you can set your fingerprints again.
