HOPE THEY GET NOTICED BY SONY'S TECH TEAM AND OFFERED A FIX (for some of these)
1 (MAJOR)
-everytime i connected my device to pc in mtp mode, many of the files on sd card are either absent or shown with 0kb size rendering my files completely useless
-reinstalling drivers did not help since the phone is detected right
-the only solution i could find is to erase data of external storage and media storage in apps and then restart
but the problem appears again when i connect it again in a couple of times
2
it has a great camera but it cannot focus when the object is near to lens (like taking a shot of 4x4 photograph)
the camera had to be taken far from the photo in order to get it focused (too far for me in terms of near focus); so whats the use of it then, the objects looks too small if taken away in order to get them focused
it doesnt focus even even u click on the object several times
3
the double click to lock screen works fine every time BUT
the same with waking up the screen does not
sometimes it even takes about 5 tries to get it unlock by double tapping
occurs more when in stamina mode
4
3.5mm jack has very low audio output in earphones or headphones (very low in youtube app, even at full volume) as compared to others and also the volume of upper and lower front speakers is different which could be noticed very easily
5
the device gets heated very quickly while using camera app or charging and hence functions gets disabled most of the time due to device heating because of charging)
Also, battery deplets very quickly (especially from 100 to 70%) even when not in use
6
while playing music its back metal panel vibrates too strongly to cause vibrations in whole body
and too much dirt gets into the space of front speakers (makes the empty space of speakers white, like dirt and sand)
----so i guess sony needs to make structural changes in future models in order to make a sturdy built device----
