@AppleSupport
I have a problem connecting to a wifi network, where it is always disconnected, I was on ios 12.1.1, and the update will help you to 12.1.4 but it did not happen. Any advice how to fix this?

iOS 12.1.4 災情：Wi-Fi 與行動網路出問題
這次 iOS 12.1.4 修補的是非常嚴重的「FaceTime 漏洞」，這個漏洞可以在你沒有接起電話時，對方也能聽到你的聲音，彷彿把 iPhone 變成隨身監聽工具一樣。雖然蘋果釋出的更新修好了這次漏洞，但根據富比世雜誌的報導，有不少網友出現「找不到 SIM 卡」、「行動網路沒有訊號」等等狀況。
在 Twitter 上可以看到大量 iOS 12.1.4 的災情：
裝置有時無法上網，但 4G、LTE 訊號顯示正常：

這次的 iOS 12.1.4 修復的是嚴重的安全性漏洞，因此若有使用 FaceTime 習慣的網友還是建議升級；如果擔心自己碰到 Wi-Fi、行動網路災情的話，可以先維持在舊版本，並到「設定」>「FaceTime」將其關閉即可。
