Force back camera use in bank app

[ElectricJozin]

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

Those permissions are part of the banking app which cannot be changed.
That's a security feature that can't be hacked.

i would take your question over to XDA. AF frowns upon discussion on how to hack or crack apps like what you want to do.

plus if those banking apps were that easy to manipulate, i would not want that app on my device handling my finances.

If it could use a picture from the gallery then anyone who got hold of the phone would have access. That would be a very bad idea.
