So back in the day on my Galaxy S5, I think, the default camera app had a setting where you could take a photo with both the front AND rear Facing camera at the same time. Has anyone seen this setting or maybe come across an app that offers this? Didn't use it a ton but do miss the option.
That was a feature that was removed with our newer updates. There are definitely some apps you could check out in your play store. I'd suggest checking out "Smart Front back Dual Camera"
