Other I watched a video about testing smartphones

[bj097]

I watched a video about testing smartphones by workers in a factory before it is officially put into box and packed. I found that when the worker was quickly and massively testing and swiping 8 phones at the same time, there was one phone which obviously showed lag or not responded as quickly as other phones among a few swipes. I am wondering when all phones are made in the same factory by the same way why there could be a few exceptions. Is it usually due to human error when the phone is assembled? Do you think Apple will have their guidelines for their factories to put away those problematic phones for further testing or will they just let them go into the market and let warranty handle the problem?

I would assume that products which fail testing aren't shipped.

Such manual work is only one of last checks that the phone is working. Lagging and responsiveness is SW related and tested much much earlier. Same as for the displays.

Isn’t all erroneous human construct/failure human error?

I would assume everything is sent out to the consumer. They are the ones that have to deal with the issues afterwards.

Really? It’s the company that incurs the cost of warranty services and reputational damage from shipping faulty product.

That would surprise me. I was loaned to a Quality Control team for a few weeks. We verified manufacturing and software conditions. If a unit was out of spec, it was flagged and returned to the manufacturer. Even down to missing or misplaced stickers, etc.
