Force app to use back camera

[Adam Labus]

I am trying to use a bank app, which wants to scan my face but only uses the selfie camera with no option to use a picture from the gallery - but my selfie camera has too bad of a image quality even under perfect conditions. I have a rooted device with lineagos.

Is there any way to: 1. Change the android kernel so as to use the back camera? 2. Use a hack/app that would hijack the JavaAPI somehow? 3. Disallow permissions for the selfie camera to provoke the usage of the back one?

I have never really worked in the android java API so I really dont know what can be done without for example knowing if the selfie and back camera have a seperate API call

Which device and banking app?

I'm going to guess that since this is a banking app, there won't be any legit way to do this -- after all, would you want your banking app to be easily hackable?
