Thanks for reporting this issue. A fix for this has just been submitted and it will be included in the next release. In case you cannot wait until v1.4.0 is out, you can apply the required changes by yourself. In order to do so, you just need to add the correct DPIs for 2020 iPhone models in this file, by applying the following patch:

What do you have to do if you are using the unity package? (How do you do this in the plugin?, I've tried doing it in xcode after unity export, but it didn't work)

UPDATE: I’ve managed to solve this for testing purposes by modifieing it in xcode after unity export, works while waiting for the next version of google vr.

This was fixed in v1.4.0.

@Excubitor @jballoffet Do you know where to find the file "screen_params.mm" or "screen_params.h" in Xcode? I am using the Cardboard XR plugin for Unity.

@chaosemer I tried v1.4.0 still getting this issue on iPhone 12
