Note that Apple and Samsung each lost market share by about 2 points. The real wiiners are Oppo, Huawei and Vivo.
Yes... Apple's and Samsung's "share" went down a little bit from Q42015 to Q42016.
But those two companies together still represent 34% of the market. Over 1/3 of all smartphones sold last quarter were made by Apple and Samsung.
Does that really make them "losers" because of a couple percentage points?
The smartphone market is 438 million units in a quarter and almost 1.5 billion units in a year.
A little change in market share for a company in either direction doesn't really mean a lot.
I see what you're saying... and you're absolutely right about Apple's and Samsung's smaller share this year versus last year.
But it's kinda insignificant in the grand scheme of things.
