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 smartphones 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.

Sony Mobile Communications Inc. was a multinational telecommunications company founded on October 1, 2001, as a joint venture between Sony Corporation and Ericsson. It was originally incorporated as Sony Ericsson Mobile Communications, and headquartered in London, England, until Sony acquired Ericsson's share in the venture on February 16, 2012. On April 1, 2021, Sony integrated its electronics businesses including Sony Mobile into one company called Sony Corporation.
