F(x) Technology is working on 6-inch handset with a slide-out keyboard design
Back at CES 2018, Motorola unveiled a few very interesting mods for the Moto Z lineup. One of these accessories was the Livermorium Slider Keyboard Moto Mod, a keyboard mod that attaches to the back of the handset and provides the full range of features usually delivered by a QWERTY physical keyboard. That mod never made it beyond the prototype stage, so its makers simply decided to turn it into a new phone instead.
Livermorium is now known as F(x) Technology and the "high-end, landscape slider smartphone" that seems to be called RealFx, Real F(x) or something along these lines is supposed to hit the market by the end of Q1 2019. Unfortunately, not much is known about the handset yet, so it would not be surprising to see it delayed once again since it was first supposed to hit the market in the final months of last year.
The upcoming F(x) Technology handset will run Android Pie and will have a slide-out keyboard, most likely identical to the one shown last year at CES as a mod for the Moto Z series. The keyboard is backlit and features Ctrl, Shift, and Fn keys on both sides for an improved typing experience in landscape mode. The only technical detail confirmed so far is the 6-inch AMOLED display with a 2:1 ratio. As for the processor, memory, and storage, we can expect at least premium mid-range specs, but it seems that nothing is set in stone yet.
Finally, it is also worth mentioning that F(x) Technology promises support for "other independent, community-driven OSes beyond Android," so those missing the legendary Nokia Communicator might be able to get a new piece of similar hardware and a degree of freedom in the software department that not many devices can provide nowadays.
