I know you only support tablets, but when the app briefly worked on my phone it seemed to run with no problems (since the update it is no longer available). Given that there is a bit of a blur between tablets and phones these days (screen sizes are getting bigger and even if it's a small screen most higher end phones these days run at 1920x1080) I'm just wondering what the likelihood is of you making the APK available for users to download and install directly - obviously with the proviso that it's not officially supported. The only issue really is that when you did a new build you'd ideally need to make an updated version of the APK available - it could easily be a sticky up on here, or just made available in the mentors forum if you prefer to restrict it.
