VCX always uses an objective approach based on measurements only and tries to stay up to date with its test method. The actual method used will always provide a good overview of the performance and quality of the camera, but it may never cover every single feature in a specific device. The VCX-score should be treated more like guidance and not an absolute as humans tend to have unique preferences.
The simple answer is No. The not so simple answer would be that, subjectivity does play a part in the initial part of the research and analysis during blind and psychoanalytical tests. Our researchers strive to find what and why exactly users have a certain preference and what parameters influence the same. those parameters and preferences are codified in the formulae and weighting and applied uniformly across mobile phones.
