Google’s Elliott Hughes has confirmed that tapping the “Check for Update” button on Android actually working now. It means if a user will be tapping the option to check for a new update once the rollout has started, he will actually get it instead of the old and frustrating message that the device is updated.
This is definitely good news as previously, no matter how many times a user would tap the “Check for Update” button, he would not get it unless he has been selected among the first batch of users (about 1% of all users). The story remained for the second batch (about 25%) which means the button was technically of no use. But with this new announcement, a user will get the update as soon as he taps the button even if he is not included in the initial batch of selected users.
In the announcement post, Hughes said,
“If you’re running a current Google Play Services, you shouldn’t need to sideload an OTA or flash a system image just because you’re impatient. When a device checks in because you’ve specifically asked it to, we flag that this is user-initiated and so you’re not subject to the usual limitations. So even if we’re at 1% rollout and 1% of users already have the update, if you manually check you’ll still be offered it, even though a background check at the same time wouldn’t.”
While he did not mention specifically, this new change is more likely to be applicable to Google devices (Pixel and Nexus series). We are not sure about Android One devices but it should become clear in coming days. As for users of Android devices from other OEMs, it looks like you will not be getting the benefit of this change as updates on your devices are handled by those OEMs, not Google.
