The phone is beauty specially the Black I own,
However I would like to go for 5.5 inches version XZ Premium ( Yet to released)
This phone got a drastic price cut recently and due to this cut some felt cheated and latter buyers feel cheer !
Con:
Battery is something you need to recharge in 8/10 hrs of heavy use else works fine for 18 hrs 100~ 30 % . This is biggest let down
specially when all the phones are used for Internet and Multimedia.
EDIT: Battery improved a lot after use of Repair option of Xperia Companion. It wiped phone fully. Now after full day average use battery remains above 50~ 60% which is safisfactory.
Camera I found bit slow on focus and not better than my superb Nokia 808pv, Infact no phone able to beat Nokia 808pv in this yet.
Hybrid Sim slot is another point specially if user wants to use Two Sim and then a swapable MC.
No FM Radio is another foolish decision many flagship phone makers are making
Heats a lot specialty Video recording and gaming But this a problem all Android phones have in common
Sun visibility is bad specially when auto brightness function diabled, Here I miss MOLED screen of my BlackBerry Z30 & 808pv
Pro:
Good looking, Its beauty.
Great screen
Near to stock android
Always updated
Good audio quality specially by earphone
Water n Dust proof up to a extent
