In December 2016 Lenovo demonstrated two foldable device prototypes. One of these devices is the CPlus, a smartphone that can be turned into a smartwatch. A few days ago Lenovo demonstrated the CPlus again, saying that such devices could be on the market within 2-3 years.

The CPlus device demonstrated now is similar to the the original one shown in 2016 - but the display size has been slightly increased (to 4.35" from 4.26"). CPlus runs on a customized Android version, includes an embedded SIM card and has a camera that can be motion triggered so it can be used in the wearable mode.
