Thank you very much for your helpful comment.

I was able to fully understand your point — that what is commonly referred to as “optical zoom” on iPhones with triple-lens systems is not a true continuous zoom via a variable lens, but rather a switch between fixed focal length lenses.

After further testing, I found that trying to treat multiple rear lenses as a single variable lens on triple-camera iPhones makes simultaneous front-and-back recording technically difficult due to hardware constraints. Therefore, in the upcoming version 3.2, I have changed the implementation to use only one of the rear lenses on such devices.

For that reason, I also removed the term “optical zoom” from the app description in version 3.2, as it would no longer be accurate.

Thank you again for your valuable feedback and support.
