Hi @breversa, just seen your message after upgrading a Samsung Galaxy A3 to the Q build and I got the same warning pop-up which keeps reappearing on every restart. However, like you, I just ignore it and apparently the phone works normally.
Was yours a new install or an upgrade? As I pointed out, there is a problem with the official upgrade instructions which seem to be similar for Samsung devices as they seem to require installing the e.zip file on a device already running Android 10. If I’m correct, as for the A3, the A5 has no stock image running a version of Android 10. Samsung in its usual way abandons older phones and has no upgrades. So my impression is that the message we have both seen is simply a Google reminder to get users to complain about not having the latest version of Android.
It would be interesting to have confirmation from /e/ developers if this is the case.
