Each new iPhone needs a hardcoded DPI value. Thats why its broken. New DPI values: https://useyourloaf.com/blog/iphone-13-screen-sizes/ See this issue if you need that hotfixed asap https://github.com/googlevr/cardboard/issues/144

Thanks @MusemoDeveloper for reporting this issue. As @johnfriedrich pointed out, new DPI values are required so as to support the new iPhones. A fix for this has been already submitted and it will be included in the next release. In case you cannot wait until v1.9.0 is out, you can apply the required changes by yourself. In order to do so, you just need to add the correct DPIs for 2021 iPhone models in this file, by applying the following patch:
