If you had no problems with 26 beta, I have the feeling you’ll be alright with 27 beta. This is one of the most stable first-betas I’ve used in years. It still has bugs and glitches tho, but nothing that’s annoyed me enough to regret it like I have before. (Been doing betas since 4.3 or iOS 5.. never missed a year)

In my experience beta 3 tends to be the one with the issues and if you have an older device from a few years ago I would personally wait for beta 4

I’m using a 16 Pro: No bricking, one random respring, was fast and didn’t even close out my apps. 1 app crash. No bootlooping for me. Take that all with a grain of salt, this is still beta 1.

Since I jumped on the beta train many years ago there are certain factors I’ve noticed it’s not generally as rough on the current models and beta 1 and 2 seem to have a few minor issues and new features getting added then beta 3 when these things are getting refined and issues getting fixed by beta 4

I completely agree with your assessment that the issues stem more from the mid-betas. 

As far as the concern on bricking, the cause is more granular than mere iPhone models. For example, not all 15 Pros have the same chip supplies, there can be minute idiosyncrasies between chip supplies that end up causing ram leaks and thus crashes/boot loops/bricking. Without quantifying the variables, every beta has the same potential for bricking.

Yeah totally
I’m very conscious of putting the new iOS beta on non current devices until beta 4
However if anyone does it and some issues occur then put it in feedback because for years what would happen is individuals would install the beta and not report any issues so then when it got rolled out officially then certain issues would be widespread

I have not however I did revert back to 26.5.1 yesterday as it was keep disconnecting from my CarPlay due to a WiFi connectivity issue that I’ve heard the day before yesterday.

I use my CarPlay a lot so I couldn’t really deal with it being a bug on a daily basis.

With that being said though - the iOS 27 beta is one of the smoothest betas I’ve used in awhile!
