I have been an android user since the start. Did use an iphone 4s for sometime and that's about it. Now, I have a strong urge to switch to iphone.
Why?
Apple is the trend setter in smartphone world, the good and the bad trends are all copied by other brands, even if it's not pro-consumer such as notch, removal of chargers/headphone jack etc. Samsung always mocks them and then copy them later. Chinese smartphones have become somewhat of an ios clone.
Android phones now lacks originality. Their updates are slow, and custom ROMs are less and less appealing (brands making hard to unlock bootloaders is one of the reason).
The only thing still keeping me from switching to iOS is price and the ability to sideload apps. And I might just switch soon if an opportunity comes.
Ps : Only attractive android phones for me is Pixel.
