Why would they make an Android phone? That seems like a huge burden without a reward. Also phones are not a place people buy premium games.
What was the last $90 iPhone game you bought?
It makes more sense to make cheap/free android and ios apps that drive people back to a dedicated gaming device that traditionally sells high cost games.
Texting images between android and ios is fundamentally broken. Images are compressed to potato quality and did mot always make it. When i had android i sent images in messenger and texted in sms to ios folks. Its a lot easier now were all on ios.
So I absolutely understand its simpler to just 100% use a different app.
