iOS 13.3 set up hot corners

Seems it is something new that is similar to what is used on the Mac. You set it up in Accessibility for accessing certain shortcuts to ease your workload. Don't worry, I had to Google it too!

I'm sorry, but your question doesn't make much sense to me. What is a hot corner? Do you mean a Hot Spot, where you can use your iPhone's cellular service to provide a Wifi connection to another device?

Edit. I guess I should have googled Hot Corner, which appears to be a sports thing. I'm clueless here.

Thanks. Still not sure I get it though? But in reading the link you posted, it says for iPad. Do you know if this is even available for iPhone? iPad OS 13 as you and I know is not the same as iOS 13 on iPhone.
