A large part of why iOS has a perception of quality is their handling of the app store.

For a frankly shocking length of time, basic actions like installing a well-rated flashlight app from the Play Store result in your lockscreen being replaced with ads.

Apple on the other hand was pretty ruthless about rejections.

Technically AOSP ("bare Android") has no reliance on an app store, but having someone vetting apps and providing ancillary services through it (Google Play Services) is so valuable that manufacturers are willing to give up a lot of control.
