Google Hangouts 服务已定于今年内退役，并会分成 Hangout Meet 和 Hangout Chat 两个 Apps，并以商业用家为对像。
最新 Hangouts App 亦不会再在 Wear OS 装置上提供。Google 表示 Wear OS 用家已不可 Google Play Store 下载 Hangouts。
用家的 Wear OS 手表本身已安装了 Hangouts App，可以继续检视讯息列, 收发讯息, 接收通知。若果用家将 Hangouts 解除安装，又或将手表 Factory Reset 就不可再有 Hangouts 了。用家若想继续用，就谨记不要 Uninstall。
Hangouts on Wear OS by Google devices will no longer be available for download from the Google Play Store.
If you already have the Hangouts app installed on your watch, you will still be able to view message lists, send and receive messages, get notifications.
