Android's "Check for updates" button not doing anything for you? Yeah, it'll be fixed next year

You know that "Check for update" button, hidden in the Android settings? The one that you vigorously tap every time you hear there's a new update for your phone... only for nothing to happen?

Yeah, turns out it's not working as intended. See, the idea is that, if there's a new update for your device, which still hasn't been automatically pushed to it, you should be able to manually start the process. But the Check for update button just doesn't work.

It was supposed to be fixed back in September, as per Google's promise, but it still isn't. Apparently, Google didn't lie — it was working at first, but an update to Play Services, which was aired shortly after, broke the feature yet again.

The bug has been solved and the "Check for update" button will work again... next year. This has been made clear by Googler Elliott Hughes, who posted on the issue. According to him, the issue was spotted and fixed way too late for a hotfix, so we'll have to wait for the next Play Services update, which will be coming (probably early) in 2018.
