What is your point? That you’re perhaps an Apple fan. That perhaps you’re not a product designer or business leader. Any product can be criticized. People like you who come on here and state obvious things like “It’s a moving part! It could fail!” Any part can fail, but it doesn’t mean it will.
The One Plus Pro 7 is passing some significant stress tests on YouTube. And if a person is that concerned about the fitness of a device, get extended warranty. Further, there are consumer protection laws, and if something has a higher than acceptable failure rate on a product, an extended warranty may occur from the company. Additionally, people’s smartphone upgrade cycle is between 2 and 3 years. The camera as tested at 300,000 times is an average of 5 years of use. Doesn’t mean, also, it won’t last many years past that.
The reality though is that I’m not the popup camera guy. I would narrowly accept it over the notch because the popup camera solves more problems than the notch and provides for a better user experience, but the ideal solution is transparent cameras and sensors in the front or ones so small as to fit in the tiny bezel.
If Apple did a popup camera, it would be ultra fast, small, only popup a small amount, be polished metal, likely rounded to blend in with the device when popped up, etc.
A person can only laugh out loud about this (It’s not a moving part! It can fail!):
