Are you using wired or wireless CarPlay?

I am positive it is not my cable, I am using the same cable I used when my phone was on iOS 26, however I did actually have a cable go bad on my recently, it was one of the Beats USB-A --> USB-C cables that was recommended for CarPlay, it worked perfect for like 6 months but I would drape the cable around my phone holder in the car and I think over time it caused a kink in the cable that would cause it to disconnect by moving the phone.

I got rid of that cable and went with an Anker one (also designed for CarPlay) and it worked perfect on iOS 26, this issue only started on 27 PB. And I haven't had the Anker cable but about a month or so.

Actually, it looks like after all my CarPlay issues were caused by some intermittent issues with the Anker USB A to USB C cable. Yesterday I was driving another car fitted with the same cable, which (the cable) was bought later and used much less, and had zero dropouts during a long drive. So today I plugged this “good” cable into my usual car (which used to have disconnects) and drove for about three hours with zero dropouts. What is strange, however, is that the “bad” cable had no issues working in my car with an iPhone 15 running iOS 26.5.2, yet would be having lots of dropouts with my iPhone 17 and DB4. Is it possible that iOS 27 feeds more data so my “bad” USB 2.0 cable gets “overloaded” and drops the connection, whereas its younger twin manages to handle it? Anyway, I have now ordered a UGREEN USB 3.0 cable, so it should resolve it.

Cable end contacts wear and get dirty..

Fair enough, but in my case the same cable in the same car works with iPhone 15 running 26.5.2 without any hiccups. So either iPhone 17 or iOS 27 betas have a lower signal noise tolerance, I guess. My Apple feedback on the issue has more than 10 similar submissions, but I will still be getting a new cable tomorrow.
 
So I don’t know if this a beta 4 thing or if it’s been there, but I just saw it. I may be oblivious, but I just found this. How long has this been a thing?

As of today, what are biggest bugs with this release? I use CarPlay wired and currently with 26.6 I have no issues. Use lots of bluetooth AirPods and other headphones, don't want issues with those. And I actually make phone calls too. Still too risky to try the Public or Dev betas?

iP17 + B4 for my daily driver, no any issues with CarPlay, AirPods and other headphones (Bose, JBL)

This is the worst 27 beta so far for the battery life and heat management alone. Tomorrow is dev beta 5. I’d wait for the next public beta to consider jumping in if you have already waited this long.
 
Anyone here using the GMail-App? Are you able to search in your inbox?
Nothing happening here after typing the query and hit the search button… ☹️

Issue on iPhone 11: Camera is blacking out constantly after taking a few pictures and sometimes very slow and laggy, not capturing photos. Once my device froze completely when I was scanning a QR code.
 
My wired CarPlay disconnection issues have now been resolved simply by replacing the Anker USB 2.0 cable with the UGREEN USB 3.0 cable. It appears that iOS 27 betas on iPhone 17 are less forgiving of signal interferences than iOS 26.6 on iPhone 15.
 
Anyone else have an issue on iOS 27 (this could also be a 26 issue, I didn’t use 26) where using the notification centre whilst watching YouTube, returning to the video causes it to freeze for about half a second? Apple feedback marked it as intentional behaviour, but this didn’t happen on 18 and why would you intentionally want a video to freeze? Lol

Have the same on my phone. Could imagine that it is some kind of battery saving behaviour? Not sure. It doesn’t look that nice. Let’s see how it turns out over the upcoming betas.
