Need OpenCV Expert for deblurring QR code

I have one application using OpenCV to detect QR code.
Btw, it is not working on Android devices (Samsung Galaxy s7, Samsung Galaxy s7 edge etc).
The main reason is that we need to use Front camera to detect QR code.
Android devices support only Fixed mode for front camera, not supporting AUTO_FOCUS and camera resolution is also poor than rear camera.
So the qr image from camera frame is out of focus and blurred.
So we do deblurred and defocused using OpenCV and then use Zxing for QR detection.
deblurred and defocused module is working on iPhone, but not working on Android.
Samsung's front camera has better quality than iPhone6, but The deblurred and defocused module is working well on iPhone6 but not working on Samsung's android devices.
It can be related with camera aperture, as you can see in below list, Samsung's device : f/1.7, iPhone: f/2.2
Here are front camera info lists.
- Samsung Galaxy s7
5MP f/1.7
- Samsung Galaxy s7 edge
5MP f/1.7
- Samsung Galaxy s8
8MP f/1.7
- iPhone 6
1.2MP f/2.2
- iPhone 7
7MP f/2.2
The deblurred and defocused module was implemented using OpenCV, C for iPhone, Java for Android.
*) QR code is small and it has fixed size (1.1 cm * 1.1 cm). Need to use front camera.
