A lot of recent devices will never even get past 4.3, so make it for all 4.x
Except for the high end or brand new devices, a lot of recent Android phones will never be updated to 4.4 (or 5), so please make the app compatible with all devices starting from 4.x (or at least 4.2)

Indeed. I wonder why it is that support for everything office 365 is available, with the exception of OWA. It just seems counterproductive.
