The family-run conglomerate is still reeling from last year's Galaxy Note 7 recall, its patriarch is on his death bed, and prosecutors yesterday sought the arrest of his son and heir on charges of bribery, embezzlement and perjury.

Samsung, whose turnover is equivalent to a fifth of South Korea's GDP, is one of several sprawling conglomerates, known as "chaebols", that dominate the country's economic landscape.
The chaebols are credited with powering Seoul's state-directed growth in the 1970s and 80s, pulling the war-ravaged nation out of poverty.
But critics say their founding families run them less as global firms and more as private fiefdoms that enjoy deep-rooted ties to the government.
"Street rallies of unprecedented magnitude apparently convinced lawmakers and prosecutors that they could no longer ignore the public anger over corporate corruption," Shim told AFP.
Lee, vice chairman of flagship subsidiary Samsung Electronics, was hauled in over accusations he bribed Park's secret confidante Choi Soon-Sil with nearly $40 million to seek policy favours.
If convicted he could been sentenced to several years in prison, but powerful businessmen have previously met lenient fates in South Korean courts.
He was given a suspended jail term, but received a presidential pardon a year later.
Lee senior was convicted of tax evasion and breach of duty in 2008 for creating secret slush funds worth billions of dollars -- again receiving a suspended jail term and another presidential pardon.
The Lee family directly own only five percent of Samsung shares but control the group via a complex web of cross-shareholdings between group subsidiaries.
