iOS 14.5.1 ruined my iPhone 7 Plus

Ever since the update, my microphone doesn’t work. Siri won’t activate, video doesn’t record sound, Facetime will not accept or make calls, Voice Memo doesn’t work, keyboard dictation doesn’t work, and worst of all I can’t make or receive phone calls.

If I plug earbuds or an AUX cable into my phone, there is no sound. My AirPods do connect via Bluetooth, but the microphone is buggy and only works half the time. On top of this my camera is lagging and network connection is buggy.

I’ve tried every type of reset and in the settings; resetting and erasing everything and all network settings, rebooting countless times.

This update needs fixing now. What good is a phone that doesn’t function as a phone?
