What do you mean iphone doesn't spy on you? 
Both android and iphone are globalist deep state spy devices. 
iphone bent over to the communist Chinese government. It modified it's OS to allow the Chinese government to have control over all iphones in Chinese. 
Your think this type of company is not spying on their users? 
I only find android buggy when you use the default rom. It's preloaded with junk and I believe from evidence in the past the modify the OS is slow down over time so you buy a new phone.
Didn't apple get caught doing this too? 

I always modify my phone with custom roms and use lineageOS or other custom roms and then my Android phone is not buggy. It's extremely fast. I love it.

I have 2 phones with lineageOS. One with google services and without. 

The one without google services is fast but not all apps work. The one with google services is fast and works great. 

Frankly. I don't like google or apple. Both globalist companies who are against freedom and need to be dismantled. They are the problem in this world.
