most people think that Sony Ericsson is short for Sony Ericsson, but Sony Ericsson is actually a Guangdong mobile phone company, so Sony Ericsson does not necessarily represent Sony Ericsson. Sony Ericsson is a joint-venture mobile phone company established by merging the mobile phone departments of Ericsson in Sweden and Sony in Japan, headquartered in the UK. Now Sony has acquired all the shares of Sony Ericsson, and Sony Ericsson has become a wholly-owned subsidiary of Sony.
