Hi Philip, Well done for highlighting this thorny issue, it's been the bane of my life when using Android since day one and unless your lucky enough to be able to upgrade your Android device on a regular basis and have Marshmallow as and OS we mere mortals will have to suffer the consequences of Google not giving a damn.
K9 is just one of the many apps that suffer from this, I have a paid for camera app (A Better Camera) which you would have thought would support external memory for storage of pictures and they also say it cant be done either even though the stock camera app does!! I used to think it was just sloppy and lazy developers but maybe it's just Google doing what Apple does to it's users (:-( -- Best Regards, Peter Mills Cut costs and help save a tree.
