I am from Russia, and Russian words are typically longer (and sometimes much longer) than English, so when I am on quick unlock screen, the "Lock database" and "Quick unlock" texts do not fit in one line. When the keyboard is active,
I do not see the input field at all (see the screen to get an idea of what I am talking about).
There are several workarounds for this (most preferable go first)
1) Use icons instead of texts
2) Enable language select in the app settings - then I can set English for this app
3) Use shortened texts
