I’m using an iPhone XR on landscape when I read my comics and I often use my left hand to hold my device.
There are times where I slide my finger to turn pages and I notice that it leads me to the bottom portion of the comic strip. Tapping on the right side of the screen perfectly turns it to the next page while leading me to the top portion but I have to use my other finger in order to do that. It’s not really a big deal but It would be better if I could tap with my left finger to switch pages.
I’m sure lots of people would find this handy because many people find it more comfortable to read with their device on their left hand.
