Don't know hype about iPhone?

I recently switch from Huawei PRO 20 which is supported by Android to the iPhone XS. Everyone brags iPhone up. So when my Huawei broke(long story) I phoned my cell phone provider and requested an iPhone. I requested!! I am completely lost with this phone. I never used Apple products before. It holds a lot of data and a lot of good features. They want you pay for a loy of apos. I had a subscription on Google Play for photo app for year. I assumed it would be usable if download Google Play and app. Nope didn't activate it. Miss my Android
