f-secure mobile security hangs after input of new license key
Problem NOT solved.
Same problem with 1-Month Abo-Key from Google Play-Store.
(First Key was from German Official F-Secure-Dealer "EDV-Buchversand" for 2 Years)
F-Secure Mobile Security App deinstalled and newly installed from Google Play Store,
License-Key Activation successfull ! (Key from Google Play Store, has to be activated on 2. May again with the 2-Year Key. Hope, that it works then.)
