Nokia Camera App needs optimization for switching from 1x to 2x optical zoom. As of now there's no optimization in Nokia Camera App while switching from 1x to 2x optical zoom while pointing at far objects.
While pointing at far objects, there's no smoothness while switching from 1x to 2x optical zoom using Nokia Camera App. Camera is getting little bit struggle while switching from 1x to 2x optical zoom.
In my Nokia 7 plus the TELEPHOTO lens is not working. It just does a digital zoom. I'm on Android Pie Developer Preview. Even when I cover the telephoto lens completely with my finger I can still see the image.
Once again cover rear bottom camera with your finger in 2x zoom in outdoor sunlight conditions. If it's still showing image, then rollback your device to Android Oreo 8.1. I think it's a bug in Android Pie developer preview.
Yes it is definitely problem with Developer Preview. The app is just not compatible with that. I also tried to have motion photos, the app instantly crashed. Thank you so much for your help. Will roll back to Oreo.
