But from an Android phones perspective it is the iPhone users that have low quality images and compatibility. Whenever someone sends me an image or video from an iPhone it seems like their phone must be terrible.

These systems could work together if Apple wanted them to. Google / Android isn't the part that is preventing interoperability. So ultimately it really is an iPhone being bad problem. They've marketed the problem well to make it seem like it is the other way around in order to make iPhones more desirable.
