Add me to the list of people screwed over by this update. I went from 2 bars in my house to 0. Installed an LTE network extender and still get no cellular signal at all -- literally 0 bars and it's 2 feet from me. No big deal, I'll use Wifi calling, which on average lasts 5 seconds to 1 minute before "call failure". My wife and daughter (iPhone 8 and iPhone SE respectively) are on 13.x and have no issues. After seeing my phone turn into a literal paperweight, I'm ensuring they don't install the update. Device: iPhone X I've tried: Airplane Mode Hard reset Network Settings Reset Factory Reset iTunes Reimaging with 14.0.1 LTE Network Extender added to my network 2 feet from me Wifi calling, no airplane mode (call never goes through, just hangs forever) Wifi calling, airplane mode (call lasts 5 seconds to a minute before call failure and dropped) VolTE on/off 3G on/off (LTE Network Extender doesn't help and 3G signal in my basement is non-existent so dead on arrival) At this point I have my phone forwarded to a google voice number so that I can actually receive phone calls, albeit while strapped to my computer. This is beyond infuriating, especially as someone who has been a loyal customer of Apple for most of a decade. If this isn't fixed soon I'm going to go to Android. The entire point of having a cell phone is being available to people. At this point if I were dying on the road screaming out my window for help would be more useful than having my phone on me.

I'm dumb and couldn't figure out how to edit my last reply so just going to post a full update of things I've tried, with new additions: Device: iPhone X I've tried: Airplane Mode Hard reset Network Settings Reset Factory Reset iTunes Reimaging with 14.0.1 LTE Network Extender purchased and added to my network 2 feet from me Wifi calling, no airplane mode (call never goes through, just hangs forever) Wifi calling, airplane mode (call lasts 5 seconds to a minute before call failure and dropped) VoLTE on/off 3G on/off (LTE Network Extender doesn't help and 3G signal in my basement is non-existent so dead on arrival) Upgrading to the 14.2 beta iOS DFU restore to 14.0.1 As of today my phone is useless even in areas I used to have strong signal outside my house. Driving to the store where I used to have 4 bars of LTE, my strongest signal, even after a hard reboot, was a single bar of 1x -- not even strong enough to make a call or send a text. I refuse to have my solution be upgrading to a new iPhone when my phone has never been dropped or damaged in any way. If this isn't resolved soon I'm just going to get an Android. At least then when there are issues I can roll back to an old version of the OS and have a functional phone.
