Phone camera app that switches to/from 4:3 and 16:9, depending if vertical or horizontal pic?

16:9 vs 4:3 - Which Aspect Ratio Should You Use?

Before you capture a photo or video, you need to decide on aspect ratio. This post breaks down the important differences between 16:9 and 4:3

The site says best aspect ratio:
Horizontal 16:9
Vertical 4:3

I have a Samsung s7 using the default camera app that came with the phone.

Is there a camera app that auto-switches between the 2 aspect ratios depending on how i hold my phone to take the pic?

I don't understand, doesn't aspect ratio depend on the sensor?

*shrug*

my phone app offers both 16:9 and 4:3 options.

i have it set to 4:3 but would like an app that auto switches depending on whether it's a portrait or horizontal pic
