At the 2007 Asian Telecommunications Exhibition, LG launched a slider smartphone called KS10 based on the Symbian S60 system. This phone is essentially the same as the LG JOY that was released at the Symbian Smartphone Show 2006 in the UK, except for some differences in the keys. The built-in system and hardware configuration are exactly the same. Therefore, the KS10 can be considered as an improved version of the JOY.
