About ProRes and Macro features are limited to iPhone 13 Pro and 13 Pro Max only, and other device models are not. If you like to shoot and take pictures, it is recommended that you upgrade.
Regarding the bug of special symbol cancellation, it still exists in the official version of iOS 15.1 and has not been fixed.
