Fair review, not everyone mentions about audio in their reviews.
"The HTC U11 was given a DxO score of 90, the highest of any smartphone. Though, we know that this may not mean much since not all smartphones are actually rated by DxO."
Bad argument. The main reason is that the dxomark is useless. Dxo cooperates with several smartphone companies and sells camera products, they also got the U11 from HTC before it was released. Therefore there is a conflict of interest. Moreover the Dxomark has a very bad reputation as the HTC 10 or Xperia Z5 were rated as the best smartphone camera. Furthermore the Dxomark is scientifically unfounded as it does not make sense to combine ratings for autofocus, image quality, video quality, etc which are totally different things. There is even neither a detailed scientific explanation how they calculate the smartphone ratings nor a detailed data set of their measurements.
