no WiFi after update to iOS 16.4.1

I have been working on my MBP to make enough space to do a backup of my iPhone so that I can clear the ‘other’ stuff. However, earlier today, I noticed doing app updates wasn’t asking for permissions to install over cell tower. Then, I noticed the Wi-Fi icon in the top right corner. So I checked a few things. It seems that there’s no more glitching in messages & other apps, and Wi-Fi is picking up routers, etc. The only thing that I can think of that was done differently was that I allowed a new iMac to use my Apple ID. How could that have cleared the glitches?

Some things that I forgot to include.

1. After the update, when a call came in, I might be able to answer it, but not by AirPod Pro 2 command. If I answered by iPhone 12, the AppleWatch8 keeps ringing. Answering by AppleWatch doesn’t seem to be working correctly. I don’t remember how this reacted to outgoing calls. I was having issues there, also.
2. For the first couple of days, I could not get the call screen to appear after answering. I could see the green phone icon in the top left corner. However, nothing happened when I tapped it.
3. Sometimes, when listening to voicemail, the sound would not go to speaker even after the speaker icon turned blue.
4. I still have issues with text msgs. When one comes in, it usually cannot be opened directly. I try opening the messages app a few times until it doesn’t crash, actually opens, doesn’t freeze on the menu item for that sender, & actually lets me into those messages. Even then, it may not allow me to reply or just freeze & crash or need to be hard closed & reopened, again.

Okay. I was going to do that. Backing it up needed to have been accomplished, anyway. However, I need to clear lots of space on my MBP to do it, which is taking lots of work.

In the meantime, I allowed iTunes to update iPhone to 16.5, but that couldn’t happen due to the lack of space for backup. Eventually, I decided to just do the update through cellular to 16.5 hoping that would fix some settings or something. After the update, I got excited, because the Wi-Fi icon was showing in the top right corner of the Welcome screen. However, when I tried to unlock it, the next screen was all white with the Wi-Fi & other symbols at the top. It would, eventually return to the Welcome screen & repeat issue. I rebooted iPhone & was able to get in to configure after update. After getting in, the Wi-Fi symbol was gone & I have the same problems with menu items freezing & needing to close & reopen things (msgs., etc.) a few times to get them to work.

During this process, I deleted some PodCasts that were taking up several GBs. Previously, I had ~45GBs free on this 256GB iPhone. Now, I have ~95GBs free.

So, I am wondering what’s the purpose of clearing the “other” category. If it’s just to clear space, I should have plenty.

Thanks for the suggestion & link. I’ve reported it & linked this thread.
