iPhone user here:
I’m sorry if this is a really controversial question, but I really enjoy the system-wide transparency and glassUI of iOS. I want to migrate to Android, but the big manufacturers (Samsung, Google, OnePlus, etc) all have a flat UI design by contrast. In my research, the closest I could find is MIUI, but the phones that run MIUI don’t support all the carrier bands in the USA. Does android really not have the option of a glassy transparent UI?
The short answer is no. Android does not use the glassy look. It has a design standard called Material You. The emphasis is on colour. When you change your wallpaper the phone automatically changes the colours in the system and in apps to match.
It’s fantastic because it’s feels like a new phone everytime.
I’d recommend you buy a cheap Android like the Pixel 7a and try it out alongside iPhone and see how you like it.
You can always sell either phone if you choose the other.
