Key doesn't work on Android 4.2.2

Tess

Hi, I have Key Premium subscription and I installed it (from Google Play) to my Alcatel android 4.2.2. phone, but Key is not working. When I enter the master password, it either says "invalid password" (even if correct) or it blocks - doesn't move at tall. I have reinstallt it couple of times already.

Key works perfectly on all other devices.

Thanks for your help!
