未來更新OS的釋出時間會提早或是能多更新幾版就是了..。

※ 引述《powerdavid (hatano yee)》之銘言：
: We're ending the year with an O! #MiA1 users, stay tuned as we're rolling out your long-awaited update in batches but make sure you're already on the latest December update (7.12.19) to receive Android O!
: 總之就是A1升級Oreo了 剛好趕在2017最後一天 距離Oreo推出大概過了半年 手上有A1的用戶可以去更新了歐
