Happy Flash Cards Update Release on Android

Version 1.6.0 has been released today with the following changes:

1. Added one more category of flash cards (i.e. Colors). We now have 5 categories and 50 flash cards in total.
2. Some users have reported that the "landscape mode not supported" error message is always showing. Probably an issue with how some phones are designed but we've fixed it anyway. Now even when the phone is in landscape orientation, the app will still show (in portrait orientation).

And the app is still absolutely free!
