There are apps that can do this but they are not exactly Bothie. The app allows the user to first take a picture from rear camera and then from the front camera (but not simultaneously). Nokia first came up with this idea in 2017.
More about Bothie
I am just wondering if this is a hardware feature or software. I can handle the software issue(with root) i think. And if this is not possible then can you please explain why and how it works?
Thanks a ton in advance : )
