HTC and Sony seem to have some things in common as far as smartphones go. Both have put out strong looking 2016 flagships that, on paper, looked commendable. Both, however, seem to have problems backing that up with solid sales numbers. On a positive note, both also happen to be at the very top of DxOMark's smartphone camera list. The digital photography benchmark site has given the Xperia X Performance a glowing score of 88, so far the highest in the list, rubbing shoulders with the HTC 10 and the Samsung Galaxy S7 edge.
