Sure, doesn't really matter. I just have to demonstrate that your "local competition" theory in pre-Xi era doesn't hold water and the real world data don't bear that out, which I already have.
Whether Samsung China's sudden sales collapse came 1 day, or 1 year after Xi? not very relevant. That being said, in Apple's case, the Chinese media's coordinated attack started on Consumer Day in March 2013, just a day after Xi became president, but because of Apple's quick response and bold risky bet, suffered no damage. Samsung China's first sales decline since 2009 on the other hand became evident in Q1 2014 and after, or some 3 quarters after Xi. Or roughly equal to a 50% drop in market share and unit sales for the entire year 2014 and more significant drops in subsequent years. So we are talking 4+ years to go from 20% to less than 1%, so there goes your timeline arg out the window, too -- it's plenty time to implement informal anti-market policies and destroy a foreign competitor completely.
Again, this dramatic drop was not seen elsewhere, but in only China, indicating that the problem wasn't inherent to Samsung's product offering, competitiveness, or market. In open markets, such as EU, Samsung maintained a steady ~32+% market share post-Xi and wasn't affected at all by the rise or fall of Huawei, before or after the ban. Samsung EU's market share dipped below 30% in 2021 for the first time in 8+ years, after Huawei's ban which further undermines the narrative that Samsung somehow benefited from it.
