This has absolutely nothing to do with that. This is a global supply issue impacting FAR more than just smartphones.
GM, Ford, Nissan, VW and others have all had to cut car production due to the global shortage. GM has stopped including fuel-saving features in some pickups because they can't get the required components due to this shortage.
It's not a smartphone issue, it's a global semiconductor issue.
It's not a semiconductor issue, global or otherwise.
I work for one of the the few semiconductor companies that makes its own chips, at least most of them. We have facilities in the US and overseas. And we also use foundries. Something like 30% or so of our business is automotive, a similar amount is industrial, a fair chunk in computing & data centers, and so on. We're active in almost every market you can name.
The trends in the use of various kinds of devices have been well observed for some time and investments in capability and capacity have been in place for some time to meet those projected needs.
What happened last year when Covid hit was that many of the large automotive manufacturers saw orders drop 80-90% overnight. And they passed that on to their supply chains just as quickly.
Spending by consumers shifted to other parts of the economy, driven by responding to changing needs driven in turn by covid - working from home, remote schooling, medical equipment, entertainment gear and so on.
Automotive demand came back quicker than anybody initially expected. Some automotive companies chose not to revise their reduced orders and to book ahead, for understandable reasons - despite being advised multiple times that capacity might become constrained quickly, as demand was looking to grow far quicker than new capacity could be brought on stream.
This situation hasn't been brought on by a reduction of capacity or poor planning by the semiconductor industry, but by an inability or a lack of desire by some major players to not order much and too far in advance, just in case. They forecast it wrong, which is so easily done.
The current demand is huge AND it's a bubble. Why would a semiconductor company spend $100s of millions or billions on new capacity that comes on stream about the time the bubble bursts?
