1) Camera is nice, but need to get used to it. Some tweaks here and there, not as simple as point and shoot.
2) Speaker quality... dual front facing speaker. The volume is low, but sufficient. The surround sound is good.
3) The DSEE HX does a very good job in earphone.
4) Warm, not hot. Running antutu is just ~60C. Usual usage is around 43C only. 

Sony treated the processor like SD 808. The maximum simultaneous is just 4xA53 and 2xA57, but the one of the A57 will go offline very quickly, maybe active for 1 or 2 seconds only.

Looks good. Yeah. One thing that I noticed, if u feel iso is high, you may adjust the brightness in SA mode, it will keep iso lower and longer the shutter speed a bit.

depend on situation.. in SA mode, software tend to pull ISO higher to get faster shutter speed, so in result u will feel picture looks grainy.. smartphone camera sensor was 1/2.3 inch, compare with 1" sensor in DSLR/camera, totally different case.. the light absorb in sensor was more than half difference.

so if smartphone can adjust shutter speed is the best.. but in our Sony software, try to use manual mode to get lower ISO and good shutter speed or there are 1 mode called ISO sensitivity, high ISO, but also can make shutter speed longer a bit.

I attached 1 photo sample with ISO sensitivity, ISO 3200, 1/8s, hold by my hand only, flash off. this photo is captured in night situation, but i want to test the camera of Z5p, so try to capture the things inside my bag with other phone like Note 4, Iphone 6.. only Sony able to capture the things inside clearly..

although Sony said our camera sensor can go up to 12800 ISO, only limited in Superior Auto, but im not sure when will trigger ISO 12800 photos, never get this before.. I do try got once ISO 6400 photo.. and quality is almost like attached.. we can see what we want to see, better than our eyes..

camera quality is very not predictive, however, when it is working correctly it is delivering gorgeous shots (if you know what you're doing, that is). no raw format output, no much thing to do in manual mode tho.
heat problem... from what i read it is a common problem for smartphone sporting snapdragon 810, but sony definitely did some things to help the heating problem, very much usable most of the time without burning my hands (but then i am using a ringke case so....)

Woah my z5p just suddenly got that sudden death thing happened, idk what happen im not playing game, it's after i use whatsapp like usual and put it down, then when i pick it up again to like 2mins it's not responding. so i press long on the power button for sometime it still did not respond, then i put it down and googled it to check what's happening when it suddenly starting to boot up. anyone else had this problem? bought it on chor 3 only already got problem?

i have only tested it with downloaded songs, not sure about streaming, but so far works for me wor
