Device: iPhone 17 Pro iOS Version: iOS 27 beta Problem Description I am experiencing the following issues on iOS 27 Beta: Bluetooth randomly turns off and on automatically • Bluetooth occasionally turns off by itself for a few seconds and then turns back on. • The issue is especially severe when connected to AirPods Pro 2 (latest beta firmware), but it also occurs even without AirPods connected. • It usually only starts happening frequently after the iPhone has been powered on for a long time. Restarting the device temporarily resolves it. 2. Network Connection Issues • Network frequently experiences lag and slow speeds. • The problem becomes particularly noticeable when cellular data is throttled to 1 Mbps. • Even when multiple strong Wi-Fi signals are available, the device often ignores them and continues using or automatically switches back to cellular data (relatively frequent intermittent issue). 3. Feedback Assistant completely broken • Trying to submit feedback through the Feedback Assistant app delay fails with the following error: 开始反馈时出错 请稍后再试。

com.apple.WebKit.WebContent process is being killed by the kernel’s memorystatus jetsam mechanism when it exceeds the ActiveHard 2048 MB limit, even though the iPhone has 12 GB physical RAM and hundreds of thousands of free pages available. This causes the exact same WebProcess → GPUProcess crash that was reported in thread 822200, but now the root cause is clearly visible in the kernel log. The crash only occurs on iPhones, never on iPads (even older ones). Environment Failing devices: iPhone 17 Pro (12 GB RAM) x 2 — iOS 26.3, 26.4, 26.4.1 Working devices (same page, same iOS): iPad Pro 2018 — iOS 26.1 (stable) iPad Pro 2025 — iOS 26.4 (completely stable) Reproduces in Safari and in WKWebView (Capacitor/Ionic app) Actual Logs (kernel + WebKit) `logApr 15 21:23:33 iPhone kernel[0] : memorystatus: com.apple.WebKit.WebContent [1596] exceeded mem limit: ActiveHard 2048 MB (fatal) Apr 15 21:23:33 iPhone kernel[0] : memorystatus: killing process 1596 [com.apple.WebKit.WebContent] in high band FOREGROUND (100) - memorystatus_available_pages: 196999 0x1110ec640 - [PID=4689] WebProcessProxy::didClose: (web process 0 crash) 0x1110ec640 - [PID=4689] WebProcessProxy::processDidTerminateOrFailedToLaunch: reason=Crash 0x117048018 - [pageProxyID=7, webPageID=8, PID=4689] WebPageProxy::processDidTerminate: (pid 4689), reason=Crash 0x1130e8640 - [PID=0] WebProcessProxy::gpuProcessExited: reason=IdleExit ... (multiple RBSRequestErrorDomain Code=4 "Target process has a higher termination resistance..." errors)` Expected Behavior With 12 GB RAM and ~197k free pages, the WebContent process should not be killed at only 2 GB. The same heavy animation page runs stably on iPad (which apparently has a higher ActiveHard limit for WebKit). Additional Notes This is not a leak in the web page itself — the crash happens even when total system memory is plentiful. The 2048 MB ActiveHard limit appears to be applied specifically to iPhone device class, while iPad gets a more generous budget. The issue has existed since at least iOS 26.3 and affects both Safari and embedded WKWebView. This seems like an overly aggressive jetsam policy for WebKit on iPhone compared to the available hardware. Could the WebContent process’s memory limit be increased for modern iPhones (12 GB+ models)? Increased Memory Limit not worked for com.apple.WebKit.WebContent. I can only add this to my app. Thank you!
