Listen, I'm a huge Apple fan. Own a Macbook Pro, iPad, multiple iPhones throughout the years.
I just bought a Samsung S6 as a secondary phone last month and first time using Android .... and I'm shocked by a few things.
* Samsung's OLED display and resolution blows even the 6S/6S Plus out of the water ... out of the galaxy for that matter. Why is Apple behind and offering low resolution outdated screens compared to the best Samsung/Android phones. Please don't bring up battery life.
I would die to have an iPhone running iOS with the super crisp Samsung S6 screen. Even photos I take on the S6 and view on the 6/6S look terrible on the 6/6S screen.
* Why isn't Apple catching up with camera capabilities ? They finally upgraded to 12 Megapixels from 8, but kept the same aperture. The S6 camera is simply fantastic and makes the iPhone 6S/6S+ camera look amateur in comparison. I'm aware if Apple tried to match the S6 camera they'd need a bigger sensor and camera would get bigger, so maybe that's the reason.
Only con I have with the S6 is the battery life. But at hundreds cheaper than the 6S/6S+ and beating it in every category except battery life, I'm kinda perplexed at Apple keeping their phones outdated.
