I am hearing/reading about these issues from all manner of people offline and online, and there are many more I neglected to mention. Doesn’t take more than a cursory glance through the iOS 17 forum to see that. But sure let’s just minimize all of that and pretend that iOS 17 is flawless.
Who said it was flawless? Certainly not me.
Everything you say may be true in your world. But anecdotal evidence is essentially worthless.
Of course you’re going to see complaints in the forums. That’s what people come here to do. Who wants to read 100s of people saying “my phone is fine”? Sensible people realize that and don’t post that or don’t ever come to the forums in the first place. That’s why I don’t rely heavily on Amazon reviews, for example. Happy customers don’t post reviews as frequently.
There might be a million people out there with any particular problem. But that’s 1/10th of 1% of the user base. No company is going to use precious resources to deal with that small a universe of affected users.
And, as I noted above, many of these problems may be due to the unique setups of the user. Corrupt backups being used following upgrades, prior jailbreaking, hardware issues, unusual app configurations, you name it, they can all cause problems unrelated to the base software integrity.
