Android setting "Lock after" not honored
There is a setting "Lock after" in the KEY Android app. Even if I set it to something very high, for example 10 hours, I need to re-enter my master password after a short while (maybe five minutes, at any rate much earlier than after ten hours).
Is this a bug in KEY, or do I have to change some setting in Android to treat the KEY app in some special way?
I am using version 4.5.5 on Android Nougat (had the same behaviour on Marshmallow).
Idea with no actual evidence: can this have something to do with the fix for the vulnerability where the master key was stored in a less secure way? (https://team-sik.org/sik-2016-027/)
