according to Wikipedia
The Xperia Play is a smartphone with elements of a handheld game console produced by Sony Ericsson. With the marketshare for dedicated handheld game consoles diminishing into the 2010s due to the rapid expansion of mobile phones with cheap downloadable games, Sony attempted to tackle the issue with two separate devices; a dedicated video game console with elements of a smartphone, called the PlayStation Vita, and a smartphone with elements of a handheld console, the Xperia Play. Originally rumored to be a "PlayStation Phone", the device shed the "PlayStation" branding in favor of the Xperia brand, running on the Android operating system.
