Just got my Xperia Z5 on Friday! I love it! It does take quite a bit of time to boot up initially, and I don't find the touch screen to be as instantly responsive as I would have expected a brand new phone of this caliber to be, but still, I'm quite pleased with it! I saw a video online where a young woman reviewing it stated that the finger print scanner was not very good. I found it to be EXCELLENT! The same woman indicated that the sound out of the dual front faces speakers sounded muffled. She intimated that it might be a result of the water proofing technology, but I found the sound to be quite clear and pretty loud! I came to the Xperia Z5 from the HTC One M7. I had my M7 for 3 years and I became spoiled for the sound quality of their front facing stereo speakers. It's one of the reasons that the Xperia came onto my radar to begin with when I was looking for a new phone. I find the Xperia speakers to actually be louder and clearer than the ones on my old M7! Not so with when listening through headphones though. The sound quality boost that my M7 had with the factory installed "Beats by Dre "software is missed. Overall though, I love the phone!
