If you've updated to iOS 14, there's a bunch of new settings you might want to take a look at. The following video shows 17 settings you might consider. Whew! You'll either be quite pleased or dismayed at all the settings. Your iPhone or iPad is becoming quite a complex device, as you'll see if you watch the video. Well, OK, maybe it has been complex for some time, but it is not backing off.
I found the tips to be quite helpful, and maybe you will too.
