LG’s new V30 smartphone is justifiably one of the most exciting Android devices on the near horizon, checking off practically every desirable feature and spec from a modern flagship-tier phone. Among its many attributes is a new breakthrough in camera aperture (a measure of the amount of light that the lens array lets in) for smartphones with a value of f/1.6. For the vast majority of people, the difference between f/1.6 and f/1.7 is not something to be especially fussed about, but for companies like LG, which fight for every possible spec edge that they can get, it’s a treasured advantage.

In past times, obsessive fans have been able to dig up information on the Google Nexus via EXIF data on pictures posted to Google+ by incautious Google employees. LG itself has fallen afoul of similar premature revelations with the Nexus 4 that it built for Google. So now the company is being extra circumspect.
