Z1s comes with a great spec and awesome design and display clarity .It has also a water proof. I am recommending you to don't upgrade it to 5.0.2.
If u do may leads to heating problem also a noticeable battery draining problems. Also I don't know, I am facing a camera hanging problems.
I didn't face such a problem with any other Sony mobiles. Also making a delay to connect via WiFi. Sometimes touchscreen is not responding to my action.
The Good Part: waterproof design, fast Processor, Best Camera, sound quality. The Ugly Part: Slippery, ES File explorer can't use. An impressive phone that eve looked. With Stunning sound and camera. With This product comes under the fastest mobile processor make me so cool and do daily database work more fast and stable.
Comes to the Design, well built and really loving it. Z1S loaded with outstanding performance and getting best in battery back up and with lots of packed offer that make impressive on camera, handy features of phone, waterproof design.
A must product for geek. Best and clear call clarity. Till now this device give me the fastest browsing experience on mobile data. till now no problem with touchscreen.With Z1S an easy use smart phone, better that Iphone 5. Z1S come with 32GB memory and extend upto 64 GB . Sonly Built Z1S Design based on OmniBalance.
