It's definitely not just you, if you hop on social media (Twitter specifically) you'll see a lot of people talking about their camera quality since iOS 14 was released.
Agreed that it'll be tough to get off the Apple Ecosystem, even for me with less than a year of being on it will be tough for me as well. But the way this iOS release has gone has definitely shown me that things aren't the way that they once were with Apple. Yes I'm just now an iOS user, but have been a long time MBP user. And I appreciated what iOS was although it just wasn't for me, and it seems like it's still not going to be for me unless these issues are actually addressed. Even here on the forums I was trying to gather information from everybody in terms of what device they had, what was the native camera app looking like, etc. . . and just getting horrible responses. Not a good experience to say the least.
As you mentioned, the app crashes since iOS 14 have been wild, and I was going to mention it in my last reply but decided not to. Even on Android with some not so popular apps, I've never experienced this many app crashes as I have after the update. And looking on the Dev Forums, it looks like there's a lot of devs that are getting frustrated because they're using the latest software version to build their code to and still having these issues.
Some of the new features Apple has provided I think they could have done a better job with, but that's for another day. LOL
Overall like you mentioned I'm not seeing this discussed anywhere but here and Twitter and not by any influencers or reviewers. And I think it's really because it might depend on the phone model as well as most might not look at or care about it because the next new thing is out iPhone 12 and they can just move onto that. I've wanted to reach out to some reviewers that I watch and provide them with links of all the people talking about the quality to see if they could maybe bring it up to their followers sometime. But I have a feeling it'll just get lost in all their other messages.
I'm at a loss here though because it doesn't seem like Apple will ever fix the bugs or allow us to downgrade, but I've definitely been looking at the new Samsung devices so we'll see where I go from here.
