Yes, I think the dogfood stage before the beta release should be more thorough. For the record, I was also adamant about this while I still worked at Google. Google, especially Android, is way too eager to release to beta. You should not release to beta until you have stopped generating new defect reports in dogfood. If you do, you just annoy the beta testers and get a huge number of duplicate reports. That is exactly what happened this year with the lockscreen bug. If anyone in dogfood had even touched the phone once the problem and its severity would have been obvious. And breaking Wallet generated 13000 duplicate reports, breaking a core use case for beta users.
