The official site listing, which has since been pulled down, featured the yet-to-be-announced Xperia Z1s with an image and was accompanied by a tagline that said, "The best of Sony for the best of you." However, Xperia Blog claims that the listing's link led to nowhere and was taken down immediately.
Unfortunately, there is no official word from Sony on the listing. Also, nothing much can be concluded on the overall design from the thumb image of the Sony Xperia Z1s.
Sony launched the Xperia Z1 f a mini-variant of the flagship smartphone, the Xperia Z1, in October under Japanese operator NTT DoCoMo's winter smartphone line-up. The smartphone is expected to be released in late December 2013.
The Sony Xperia Z1 f (SO-02F) features a 4.3-inch TRILUMINOS HD (720x1280) display with X-Reality for Mobiles. It is powered by a 2.2GHz quad-core Qualcomm MSM8974 processor along with 2GB of RAM, much like its elder sibling. The Xperia Z1 f runs Android 4.2.2 Jelly Bean out of the box and is manufactured by a single aluminium frame with tampered glass on back and front panel. It comes with 16GB of inbuilt storage which is further expandable up to 64GB with the help of microSD card.
The highlight of the Xperia Z1 f is again the 20.7-megapixel Exmor RS sensor alongside BIONZ image processor engine and pulsed LED flash, as seen in Xperia Z1. It also includes a 2.2-megapixel front-facing camera. Connectivity options on the device include Bluetooth, Wi-Fi, GPS/ GLONASS and NFC. The Xperia Z1 f packs a 2300mAh battery with STAMINA mode and is waterproof and dust-proof smartphone, like other high-end Xperia smartphones.
