precisely which android client was he using? (and can he submit a bug report from it?)

My guess is that you were trying to do new-style verification, which requires RiotX, which is shortly going to replace the old Riot Android client.

I think he was using the old client, yes. I will ask him to file a report, I tried RiotX and it seems to work well.
