The Google Camera port now works on LG smartphones with a wide-angle lens
The Google Camera port for non-Pixel and Nexus devices came out in August 2017. The application worked well, but not at all. For example, on some dual-camera devices, it did not even start. And this is logical, because Google does not have a smartphone with a dual module. But one participant in the XDA forum solved this problem.
Manufacturers install the second camera module for different purposes. LG decided to make it wide-angle. Therefore, the user with the nickname cstark27 set out to update the Google Camera port for LG smartphones. And he succeeded. Now the application runs on G5, G6, V20 and V30. While there is no information, will this version work on smartphones from other manufacturers with similar modules. But it's easy to check.
