I never had a Pixel 6, that phone is indeed plagued with more issues, also because it’s the first chipset developed by Google. I did have the pleasure of using the Pixel 6a for a while, couldn’t find anything wrong with it, except for the fingerprint sensor. Friends that are not tech savvy can point out the flaws of my FP4 in minutes as well. I remember these discussions with you, but that was when I returned my first FP4 due to persisting issues and asked if those issues were solved. That was not in my initial questionnaire about the phone. Back then the phone could shoot rainbows and was flawless, as some still insist it is.
Now don’t get me wrong. I can get rid of this phone any minute. The reason I underscore these issues is because for some reason people want to make this phone sound better than it is. I really don’t like seeing that. Let’s just describe the phone as it is, not as you want it to be, or why you feel good about it. For now I’ll still put up with the flaws because I do see the value in the mission of FP. But as time progresses and bugs don’t get resolved, it does wear down on me.
I may try it one day, when it’s possible to go back to the native FP version without bricking it. That seems like an issue. I expect the next hurdle with a custom ROM will be the apps. I suppose they need Play Security enabled as well. Since this is my only phone and use it for work, I don’t really feel like messing around.
There is effectivly no other choice than stock FPOS if one needs fully supported real Play Services, nobody ships GApps by default and flashing it afterwards will not let you lock the bootloader (and is a method always prone to failure).
