Android 系统由 Android 10 开始就有 System-wise Dark Mode，不过 Apps 还是逐个逐个改进，Google 旗下的 Apps 亦陆续加设 Dark Mode，稍后三个办公应用 Apps Google Docs, Sheets 和 Slides 亦会有 Dark Mode。
根据 9to5Google 拆解新新版本的 APK 档案，发现内里有新增数个关于 Dark Mode 字串，这些新增字串都是介绍 Dark Mode 的，例如 Welcome to，似乎 Dark Mode 已经差不多完成准备推出。其实在之前版本的 APK 档案内，亦已加添了一些相关的 Dark Assets 资源档案。
<string name=”dark_doclist_promo_title”>Notice anything different?</string>

另外，Twitter Alessandro Paluzzi @alex193a 亦贴出了数张 Google Docs Dark Mode 截图。可以看到深灰色背景衬白色文字，用家亦可以自行开关 Dark Mode 又或跟随系统设定。
