Since this is my first iPhone, how does the quality control compared to the last model, was it built better (i.e. no scratches, dents etc...)
They are all mass-produced in China. Take that for what it is...
That means nothing as the build quality varies widely between iterations of iPhones. When the 3G/3GS with its crappy build quality first debuted, people were worried we were stuck with the inevitable as it was now a mass-produced device on a much wider availability on contract. That changed with the 4/4S with the best build quality of all iPhones to date.
Original iPhone - very good build quality/fit and finish
3G/3GS - bad build quality and poor fit and finish due to plastic (cars with plastic body panels like Saturn have this same problem)
4/4S - excellent build quality and fit and finish
5 - Too early to say conclusively until they fix the QC issues
My iP5 has flawless metal housing but a bit poor fit and finish where the glass strips meet the aluminum body. My mother's iP5 has excellent fit and finish where the glass strips meet the aluminum body but arrived nicked and scuffed out of the box in three places. However, except for the factory damaged nicks, the build quality itself is significantly better than the 3G/3GS and might be comparable to the 4/4S.
Don't confuse weight with build quality because it has nothing to do with it. Rather, it's how the material is pieced together as the final product.
I had both the 3G and 3GS and BOTH were flawless as far as quality and build goes. Didn't really know anyone else that had an issue with them either.
The 4 and 4S on the other hand...
Fit and finish is also part of build quality. Did you consider that? All the 3G/3GS I've handled was worse in that respect simply because of the plastic (no different from how cars with plastic body parts are notorious for poor fit and finish). The 4/4S may or may not have more internal problems but is definitely better when it comes to fit and finish.
Just because the 3G/3GS were made of plastic on the back does not mean they were bad fit and finish/build quality.
Fit and finish is regarding things being flush and symmetrical and nice and tight. I really struggled to find a 4S that had good fit and finish. Having a nice combination of glass and stainless steel doesn't mean much if the other components and hardware are not up to snuff.
The only reason I think the 4 has better build quality than the 5 is because of thick steel vs. thin aluminum. I will never run caseless in fear of it bending. The 5 has better, more responsive, consistent buttons though.
Right, because $2 of plastic will keep the iPhone from bending![]()
