Google Engineer Details How Updates Are Rolled Out To Nexus Devices
谷歌工程师解释NEXUS装置的升级流程是如何被安排的



Have you ever wondered how Google rolls out its updates to its Nexus devices?
Well for those unfamiliar, updates are typically rolled out in phases, but thanks to a thread that has been answered by Google engineer, Dan Morrill, he has shed some light on how the rollout process works, which hopefully will let you have a better understanding of updates done OTA and why sometimes you have to be patient and just wait it out, instead of mashing the “Check for updates” button, which he claims will do absolutely nothing in terms of bringing you the update faster.

是否好奇谷歌是如何安排NEXUS装置升级流程？
对于那些不明白的用户，升级都是分阶段 / 批来进行。
感谢谷歌工程师在某论坛的回答，他把安排升级的流程向我们揭秘。
他也希望我们明白升级所有NEXUS装置是如何完成的。
还有就是，与其一直SPAM装置上的"CHECK FOR UPDATE"按钮，用户还是必须耐心等待，因为那个行为不会加速你的NEXUS装置的升级。

According to Morrill, the first 24-48 hours of a rollout are typically reserved for 1% of devices and Google will wait to see if there are any reports, which if there are, the update will presumably be halted temporarily until Google fixes it. However assuming nothing goes wrong, what happens next is that the update will then be pushed to 25% of devices, 50%, and finally 100% over the course of one or two weeks. This is a surprisingly long process but like we said, now that you know, don’t worry if your friends got the update ahead of you  because it will arrive for your device eventually.

根据工程师的解释，首24-48个小时的升级是保留给1%的NEXUS装置，之后谷歌会等待看看是否有任何问题的呈报。
若有此类的报告，谷歌会暂停装置升级（伺服器的升级文件不会再发送给用户），一直到谷歌把问题解决。
若一切正常，接下来会发生的事——把升级的范围扩大，达致25%的NEXUS装置，接下来是50%，到最后100%，这阶段会在一至两个星期完成。
这是一个冗长的过程。别担心，若你的朋友已经接收到升级，而你却还没有接搜到，那项升级最终还是会临到你的装置上。

Interestingly enough according to Morrill, it seems that this is done on random, and that when your device “checks in”, there is a chance of it being offered the update, but assuming it doesn’t get the offer, you will then have to wait for the next batch. For example if you missed out on being in the 25% batch, you’d have to wait for the 50% batch, and etc. Pretty interesting stuff, isn’t it?

根据工程师的解答，有趣的是这项升级流程像是随意安排的。
当你的装置在伺服器上CHECK IN的时候，它将有机会被安排升级。
假设你没接收到，那么就得等下一阶段 / 批。
这很有趣，不是吗？

过了18个月的周期就列为旧产品，淘汰了，所以就不升级了。。。
不然厂商哪里来赚呢？厂商就是看见大家爱慕虚荣，喜欢SHOW OFF的心态，出了一大堆不必要的装置，大家一致努力买，把钱花光为国争光，导致厂商随便出什么，都有人去买，不担心亏损。
