Same reason NFC payments on Android were super niche for years before Apple finally implemented it

I’m very interested in why you think that. Do you have numbers?

The concept of a mobile wallet was invented in Kenya in 2007 with no input from Apple. That then spread to East Asia where in China, not NFC payments but QR-code payments have been a thing since 2011 and they have barely caught on in the West. There are massive developments and usage of different technologies happening outside of Western countries of which the majority are now on Android simply due to price.

Or why so many apps don’t use Android features that would improve them because iOS doesn’t offer that feature

Which features are these?

Are you an Android user? And which continent are you on? I’m guessing your views are very much centered around a personal experience in a single country or even region, but I may be wrong.
