Camera rendering on Android is subjected to software. 

Even with comparable cameras on Instagram, I used to get post processed to fuck making every high quality image look 240p or less. 

Imo it felt like it was engineered this way by the developers, preferring and testing iPhones rather than Android. (But Android has more variety so, ) 

QR should work in the camera app without the need for any additional apps  

 I need to readout WireGuard config so it is not a small QR 🤔 

 Maybe it works reading the QR data with another app and pasting it into WireGuard?
In the end every QR is just a string  

 Btw this was like in 2016. 

I don't use legacy media anymore.
