over in the "Sony Xperia XZs Goes On Sale April 5" discussion:
Cool features not available in US market?
No Battery Care and no fingerprint sensor for phones sold in USA market? Makes no sense. Looks like a really good phone LTE-band wise (LTE (Bands 1,2,3,4,5,7,8,12,13,17,19,20,26,28,29,32,38,3 9,40,41) and the crazy megapixeled cameras. Also don't see any documentation about it being a dual-SIM phone - even though it says so on their website, nothing in their White Paper or User Manual confirms. Typical Sony confusion.
