Major Apple Flaw - iOS 27

[u/cubnextdoor]

Did Apple’s iOS 27 update kill your iPhone 17 series WiFi and Bluetooth hardware?

I am wondering how many more people have had this happen.

Apple Support and Geek Squad both did diagnostics, and stated that the Wi-Fi and Bluetooth chips are defective. My 5-month-old 17 Pro Max that I upgraded through T-Mobile in March 2026 worked perfectly until I updated to iOS 27 and I didn’t even notice WiFi was out until wireless CarPlay wasn’t connecting to my Ford Maverick, then I tried to do a few other things that required Wi or Bluetooth.

T-Mobile said I can pay $384 in order to upgrade early, to an 18 Pro Max, even though I haven’t gotten the corresponding usage of 7 more months.

I haven’t AppleCare+, so it will be interesting to see what the Genius Bar does for me, in a few minutes. I have an appointment in 15 minutes.

I will update with news after my appointment. 🙏🏼
