上星期初 WhatsApp 為 iOS 版本更新，加設 Call Waiting 來電待接功能，現在亦為 Android 版本推出相同功能。
在 WhatsApp for Android v2.19.357 版本，加設了 Call Waiting 功能，形式就如平使用電話的 Call Waiting 一樣。當在 WhatsApp 使用語音通話時，若有來電時就可以選擇是否接聽來電。
What’s new
– New privacy settings allow you to control who can add you to groups. Go to Settings > Account > Privacy > Groups to get started.
– Added call waiting support so you can choose to accept an incoming WhatsApp call while you’re already on another call.
– You can now require a fingerprint to unlock WhatsApp. Tap Settings > Account > Privacy > Fingerprint lock and enable Unlock with fingerprint.
– Fixed an issue which caused fast battery drain on some devices.
新版本已經在 Play Store 推出，但應該是分階段推送，所以可能要再等一些時間才會有更新。
