Since the iPhone X-series models have no Home button, new users sometimes struggle with how to exit apps and get back to the Home screen. The Home indicator line at the bottom of the screen is the key to doing this. However, it is important to realize that this line is at the bottom of the screen in any orientation. So it won't appear on the right when you are playing a game in horizontal mode, but at the bottom of the screen under the game or sometimes over the graphics at the bottom of the game.

You can take RAW photos with your iPhone, you just can't do it with the default Camera app. Apple does allow third-party apps to access the hardware and software needed to take RAW photos, so you can use one of the many options to do it. RAW photos provide a lot more flexibility than HEIC or JPEG photos, but with a much larger file size. Using a third-party app means you can keep using the Camera app for regular photos and use the other app when you want to take RAW.
