There had been chatter for years that LG would quit the smartphone business. It was once the world’s third-bestselling mobile brand. These days the loss-making business doesn’t even make the global smartphone top 10 list. Market research firm IDC places it 11th. But its decision to finally give up marks a significant moment. Not only because it might be the catalyst for other struggling companies, such as Sony, to make the same decision. But also because LG had distinguished itself by trying to offer something different to the rest of the market. It was only in January that it teased what had been intended to be its next innovation: a handset whose screen would have expanded in size by rolling out more of its flexible display when required.
