Learn something new every day! I finally found specs for my phone camera that list more than just the megapixels and sure enough, it's 4:3. Then I searched for and found the setting that changes the aspect ratio, because mine was set by default to 16:9.

Thanks!

You are welcome! I too was misunderstanding this. I had set my phone to 16:9 specifically thinking that was the native resolution. Egg on my face when I realized it was wrong.

Here's yet another person who needs to check his phone sensor's specs...

... native 4:3 and was already set correctly.

I feel like we just the tip of the iceberg and many other phone shooters are scrambling to check but keeping mum about the results.

They should all speak up here. Gets us closer to the K-1ii giveaway!

My LG G5 gives 16:9, 4:3, and 1:1 aspect ratio controls.

How to View & Take Photos in Widescreen (16:9) on iPhone

I checked your third link to read about my iPhone 8 plus and it's 4032 x 3024 (4:3). Printing at 300 dpi, that would be a native 13.44 x 10.08-inch print. I do not find any store offering a mat opening that's 13" x 10". 12" x 9" mat openings factors into the aspect ratio for a setting of 336 dpi. Who on earth prints at 336 dpi? (Okay, I just set myself up for someone to say "I do!") Epson's incremental dpi setting is based upon 360 dpi, which is what I use. (Incremental meaning print driver settings of 360, 1440, 2880 dpi.)

It's just a strange mathematical world!

There's no rule requiring you to print at an even DPI value. If you don't scale the image yourself the printer driver will generally do it for you.

Indeed . . . but for my art prints I have been following some guidelines set out by Jeff Schewe in his book, The Digital Print. I try to stick to the printer's native printing resolution for my art prints. For other prints I don't worry about it. Schewe wrote,

The Finest Detail option is unique to Epson (although Canon pro printers also have a high-resolution reporting option as well). Normally, the Epson printer’s reported resolution is 360 dots per inch, and the Epson Pro printers actually have 360 nozzles per inch on the printhead. When you select Finest Detail, the driver reports to the print pipeline that the printer is a 720-dots-per-inch device. This is a critical thing to understand. If you were printing a textural fine-detailed image and the native resolution, uninterpolated, is above 360 pixels per inch, you’d want to upsample to 720 and select Finest Detail" [page 186]. He notes later in the book that if a image scaled for printing has a resolution higher than 360 dpi (his example has a print resolution of 424 dpi), he sets the Print Resolution in the Print Job panel in Lightroom to 720 dpi and sets the Output Resolution to 2880 dpi to create the best possible print [page 248].
