h2. Notes for iOS
unity-freeze-ios.zip is recommended for testing on iOS. It is recommended that the test device is kept very cold to improve the reproduction rate; place the device on an ice pack to ensure it stays in Nominal Thermal State. An overheating device reproduces this issue much slower.
Build and deploy the app to iPhone 16 Pro / Pro Max, press the green button and wait for the app to hang.
