Megapixels count as well. I have used the first HTC One(2013). Though the photos taken looked good(not better than Samsung GS4 and Nokia Lumia 925 for example), once you zoom in the pic you have taken, details are lost. 4MP is non sense. The rest of the HTC One (M7) is amazing but not that camera. I'm using a NL1520 now and knows ultrapixels were a joke.
