原標題：Google Publishes End-of-Life Dates for Guaranteed Nexus Support
來源：http://goo.gl/Y8xCN2
One of the major reasons why Android enthusiasts opt to purchase a Nexus device
are the guaranteed updates. At its Google I/O conference way back in 2011,
Google initially tried to get its partners to provide software updates for
their devices for at least 18 months.
為什麼 Android 愛好者選擇購買 Nexus 裝置，其中一個主要的原因是它的保證升級。
回到 2011 的 Google I/O 會議，Google 原先嘗試使它的夥伴提供它們的裝置至少 18
個月的軟體升級。
While many devices unfortunately received the cold shoulder when it came to
the latest flavor of Android, for the most part Google kept its own promise
and provided quick software updates for most Nexus devices (we’re pretending
that the Verizon Galaxy Nexus never happened). Over time, Google has refined
its update policy to be more transparent to the end user starting with the
introduction of the Nexus Security Bulletin (now known as the Android
Security Bulletin) last year. With this announcement, Google began rolling
out monthly security patches to all of its Nexus devices that are promised to
continue for the longer of 3 years or 18 months after the device is delisted
from the Play Store. Additionally, Google promised to provide major Android
version OTA updates for 2 years after the device’s initial launch.
然而許多裝置不幸地受到了冷淡的對待，當它們來到了最新的 Android，大部分 Google
遵守它的承諾並且對大部分的 Nexus 裝置提供快速的軟體更新(我們裝作 Verizon
Galaxy Nexus 從未出現)。隨著時間推移，去年 Google 對於終端使用者從加入 Nexus
Security Bulletin(現在作為 Android Security Bulletin 所知)開始已經提供它的升級
政策更加透明化。隨著這個公告，Google對於那些被承諾持續長達 3 年或是 18 個月的
所有 Nexus 裝置開始推出每個月的安全修補，隨後這些裝置將在 Play Store 中剔除。
另外，Google 承諾提供在裝置最初推出後兩年的主要 Android 版本 OTA 更新。
While the security bulletin was a major step forward in encouraging Android
OEMs to provide software support for their devices, one major issue remained:
when exactly will software support end for a device? For those of us who
would prefer a more exact timeline, Google has just published a table
indicating the end-of-life date for certain Nexus devices. Oddly enough, the
table is missing entries for the Nexus 4 or Nexus 6, though in the Nexus 4’s
case the device is long past its end-of-life date and for the Nexus 6 its
support will end in about 5 months.
當安全公告成為主要的步驟來鼓勵 Android OEMs 提供這些裝置軟體支援，一個重要的議
題被留下：何時對於裝置準確地提供軟體支援完畢？對於我們這些篇好準時的人，Google
已經公布表格指出對於確定 Nexus 裝置終止。奇怪的是，這個表格完全缺少了 Nexus 4
或是 Nexus 6，雖然 Nexus 4 這個裝置已經在過去結束生命週期並且對於 Nexus 6 它的
支援在 5 個月後結束。

This is the final date after which your device is no longer guaranteed to
receive a major Android software update. If you’re looking to taste whatever
the latest flavor of Android is poised to be released after your device has
reached the end of official Google support, you’ll have to head over to our
forums and flash a custom ROM. Remember though that you will still be
receiving monthly security updates for your devices so long as you’re still
within the eligible time-frame, and maybe a regular update or two if history
is to repeat itself. We’re hoping that Google will provide official
end-of-life dates for when they will no longer provide security updates as
well. Finally, and this one is a long-shot, here’s to hoping that OEMs will
follow Google’s suit in providing us with a roadmap of when their devices
will be left in the dust.
這是最終日期，在此之後你的裝置將不再保證收到主要的 Android 軟體更新。如果你已
經到了 Google 官方支援的終點卻希望嚐到最新 Android，你將勢必前往我們的論壇並
刷客製 ROM。記得你的裝置只要仍然在符合條件的時間內將持續收到每個月的安全更新，
如果歷史重演，可能會有一兩個一般的更新。我們也希望 Google對於那些不再提供安全
更新的裝置提供官方的終止更新日期。最後，這個希望渺茫的是，希望那些 OEMs 會跟緊
Google 適當提供那些不見別人車尾燈的裝置一個路線圖。
心得：
對於Android的升級很重視的人，相信會盡量選擇Nexus或是對於軟體更新相當重視的OEMs，
像是HTC或是LG?其實SONY也不差，我手上這隻老Z還吃得到SONY官方的5.1.1，已經覺得
SONY無愧於這隻老旗艦，只是可能等待時間需要久一點。
另外我沒有非常關注以往Nexus裝置Google最終終止更新的時間，據說似乎都比18個月還
來得長?不過以台灣來說，會選擇Nexus的應該都是喜歡乾淨流暢的Android系統，甚至不
少人還會在產品生命週期結束後去尋找其他資源來更新自己的手機。
另外，如果有看內文應該也會覺得奇怪，怎麼Verzion Galaxy Nexus會被排除在外XDD
難道是Google爸爸的私生子嗎XDD不知道是不是OEMs的問題還是其他問題?照理來說掛上
Nexus的標誌應該都是Google爸爸包辦的。
最後也希望各個OEMs能夠讓消費者準時享受到新口味的Android。
