Seems strange to be concerned about smartphone sales during an epidemic but okay
World keeps spinning.
Smartphone sales are big business for China. A huge part of their, and the world economy.
Either this epidemic will burn itself out, or we all end up dead. Sooner or later, money changes hands, and business is business.
To not be concerned with smartphone sales during an ongoing epidemic could be suicide for some companies.
Even in the worst of times, and the face of certain death, someone's gotta run things. Those people need information to make decisions that are based on the best information when the troubles pass.
A lot of lives, jobs, and futures are ties to smartphone sales, so yeah, it's important to track it even during an epidemic....
