I have a similar problem as @awioa007 does, but I had It from pretty much the beginning of using this app.
Starting from a complete restart of my tablet:
I launch Facer app and I need to log in (I do it), then I minimize it and after some time open it via unclosed apps menu and I need to log in (I do it), then I minimize it again and after some time open it via icon (shortcut) on my screen and I need to log in again (I do it).
Not to mention, that I also need to log in every time I manually terminate Facer app from unclosed apps manu, or when I restart my tablet.
I had this problem from 3.1.3 public version (but I belive I had it before as well): http://community.facer.io/t/facer-android-3-1-3-released/3575/10?u=mellin
I thought it was becouse of my RAM usage but I recently checked that option and it's not the case.
