The pc companion will detect the smartphone...

Don't upgrade to 4.4.2 z1 kitkat...it drains u r battery a lot...even when u r phone is in idle it looses battery charge upto 20-30% battery charge in 1 hour...media server and media apps are running on the background and using upto 80% of the battery even in idle..phone is getting over heated..charging battery time increased from 2 hours to 4hrs...battery draining very fast...very bad update from Sony....hating my phone&sony
jack, 22 Feb 2014You need pc to upgrade your cp to 4.3U can download also by wifi the upgrade.
So it's confirmed yes the kitkat is out and running on my xperia z1 in india..but does it makes it too much as I am yet to find out a great advancement from the later version..Personally not a real gr8 fan of Sony but with this update feeling a bit more responsive..Jus only a bit but the phone still crashes which is still not a great sign..With hardly nominal usage the flagship fails shame shame shame!!!

Finally I got satisfied of this phone. Don’t worry to buy(got) this phone- its worth able. Every one told this phone has a overheating issue, but me too face that heating problem. First u can notice this one, this mobile is water proof, so mobile body will closed each and every side. The heat can’t came as much as do. And its also a steel body(I think now u understood). S3 and S4 also has a same heat issue. To comparing those phones Z1 has more advanced higher end phone-(like camera on low light, cpu on 2.2GHZ, 2 gp ram, 1080pixel, 16gp etc…………
Just got 4.4.2 update for Z1 in India. But there is no significant change. Atleast they should have added wake screen on tap feature they provided on Z2.
Few changes like automatic answering machine and emergency call are fine.
Its time android brings in some innovative features now.
