I went through an unintended restore of an iPhone and lost a jailbreak tweak I know exist.
What it did was basically enhancing the original functions of the “Portrait Orientation Lock” control center button for iPhones, and added the function to also lock in landscape. (This is something iPads are supposed to be able to do, but iPhones normally aren’t.)
Very simple jailbreak tweak, and worked better than any other predictive work around sto achieve the same.
It worked on iOS 14.3, but may have been developed earlier, and never officially tested for this version of iOS. Therefore, any tweaks that do this marked for earlier versions of the OS would be welcome.
This feature is available on all iPads, and many, if not all, Max-size iPhones (for e.g., iPhone X(S) Max, iPhone 13 Pro Max etc.); however, it has been OEM blocked from iOS to support non-Max-size iPhones.
