camera resolution

[ankitvaluepitch]

at the point when I found an image from the camera of MLKIT , it's resolution is 7681024 . but when I click the picture from my device native camera it gives me an 8 MP , i.e. 32642448 resolution image. so somehow I want to use this greater resolution image In MLKIT, which my device can capture as it's full capacity.so how can I increase MLKIT camera picture quality?

because when I get the face from the MLKIT camera picture, it also has low picture quality and I get lost my accuracy.One more thing here I am using the front camera for all.

if possible I can get the accuracy for the face more reliable.
