I like this kind of input because it displays use cases and problems that I haven’t thought of which is exactly why I made the post, so thanks for saying all this and taking the time for that.
That being said, I’m not trying to fight but I’ll give my perspective of how I feel about the issues you raised as an average user just to provide some context in case anyone is concerned about this stuff.
The keyboard is absolutely something that, if android keyboards are a must for you, you might be upset by. I have yet to customize my keyboard at all so I’m trying the default layout for now. I don’t mind the app bar because it isn’t any worse than the few keyboards I used on android. Swipe to text works fine for me but autocorrect does occasionally get words wrong. Not any worse than my android keyboards though (I’ve tried all the major ones out there too). However, I’m fine with my typing pace on iOS, so that doesn’t bother me. I have a couple UX complaints with it but nothing to make me ditch the phone. Might just take time for me to get comfy.
As for messaging, I noted a lot of what you said in the previous post I made. Not having RCS is their fault, it sucks, but if the EU gets it figured out it may tempt me back to Android. I don’t mind the messaging app so far because it does provide a lot of functionality for socializing that Googles alternatives just don’t have or are done poorly. Not everyone will use the entire messaging app but a lot of the complaints are niche to me. Ive never even heard of AMR files. Also I believe searching for messages is being added but I agree that its absence is rather odd.
Connectivity does suck. Hopefully it will improve on newer models but again, I hardly ever have a reason to connect my phone directly to my PC. I back up all of my photos over wifi so I have no need. In fact, my previous phone was used only a handful of times for file transfer. So it isn’t important to me and I don’t think its important to average users, but its a good note and I hope a switch to USB-C will improve that.
Also your situation with PDFs is odd. I’ve had the opposite experience as I actually took a short vacation the past week with my device. It brought up and stored the event emails, tickets (in the wallet) and maps that I needed for the event pretty easily. I definitely had to open a couple of PDFs but maybe it used my connection. So I’ll say that I’m not sure what thats about but I’d bet an app can solve that problem.
Your last point is a mixed bag. Community support is hard to find but if you’ve ever looked at forums asking google how to fix something its pretty much the exact same thing. Only difference is that a workaround is usually possible but requires a bit more effort. Like uninstalling their default apps for instance. Or changing the per-app notification sound (may be fixed now idk). When I tried to search for those things, all the google responses just said “pound sand, we’ll add it to our totally real feature request list”. Still, adaptability is more an Android thing for sure.
