First with Retina display, first with desktop grade storage controller, first with 3D-touch, first with reversible connector , first with truedepth, first with those image and video compression codecs, etc.
How many of the competition’s innovations have survived and proven to be not gimmicks?
Now you're playing into Dolby's marketing hype for the iPhone. You believe the bullsh*t.
It was not first in ANY of those... besides Face-ID.
Retina display - Just a marketing term for pixel density. Retina display has no meaning outside of Apple talk. Apple had tiny displays, so they crammed more pixels into a smaller space. HTC and Samsung were the first to bring HD (1280x720) displays to the market, and the first with high-resolution QHD etc.
Desktop grade storage controller - Samsung was the first to introduce desktop grade UFS2.0 storage to their Galaxy S6 line in 2015. Also Apple is STILL using USB2.0 for the lightning port in 2022!
3D-Touch - Marketing gimmick - it was just haptic feedback with a physical pressure point that was quickly ditched by Apple.
Truedepth? WTF is that? You mean Face-ID? Yeah Apple pretty much has that nailed - I'll definitely give them that. Also there is no other phone that comes close to Apples Face-ID security.
Image and video codecs - Apple was the LAST to implement HEVC and HD video recording. Samsung beat Apple by 4 years introducing HEVC support with their Galaxy S4 in 2013, with Apple only introducing it in 2017.
My point being - they take their time to test and implement technology to the point where it's pretty much indestructible and robust to be reliable and give consistent results. In doing so, they will keep the same technology active for years, until they can reliably replace an existing technology with the new, and ensure it works just as reliably.
One thing that they are always first in though, is the performance of their A-Bionic processors. There they are leagues ahead of the competition, but no doubt that's due to the extremely controlled closed-loop system of hardware and software development thrown into only one device. Efficiency.
